Background: Morbid obese patients with type 2 diabetes mellitus (T2DM) and a body mass index(BMI) >35
kg/m2 benefit greatly from Roux-en-Y gastric bypass surgery (RYGB). Whether the patients with T2DM anda body mass index (BMI)<35kg/m2 also profit from this surgical procedure is not known. In Asian Taiwanese,
the risks associated with T2DM and cardiovascular diseases occur at a relatively lower BMI levels. We
examined the safety and efficacy of RYGB in Asian Taiwanese patients with T2DM and a BMI of 22-35 kg/m2
in a referral medical center.Methods: A total 62 consecutive patients with T2DM and a BMI of 22-35kg/m2
underwent RYGB between 2003 and 2009. The data were prospectively collective before surgery and at 3,
6 and 12 months after operation. Results: Of the 62 patients, 15 were men and 47 were women (age 40.1
± 10.1 years). Their preoperative characteristics were BMI 30.2 ± 3.2 kg/m2, body weight 81.8 ± 11.8kg, waist circumference 100.6 ± 10.4 cm, and duration of T2DM 5.9 ± 6.0 years. There was no mortality,
major surgical morbidity, or excessive weight loss experienced. The BMI decreased postoperatively by
20%, from 30.2 ± 3.2 kg/m2 to 24.0 ± 2.8 kg/m2 (P <.001). The fasting blood glucose level decreased
from 194.7 ± 70.4 mg/dL to 99.8 ± 28.4 mg/dL (P <.001), and the hemoglobin A1c decreased from 9.1%
± 1.7% to 6.0% ± 0.9% (P <.001). The 10-year cerebral and cardiovascular disease risk was estimatedwith UKPDS risk engine before and after RYGB. The risk for fatal and nonfatal stroke and coronary heartdisease decreased essentially. Conclusion: RYGB safely and effectively remits T2DM in Asian Taiwanesewith a BMI <35 kg/m2. It also lessens the 10-year cardiovascular cerebral disease risks. More larger,
longer term, prospective and randomized studies are needed to confirm these effects.

Background:Non-alcoholic fatty liver disease (NAFLD) is increasingly being recognized to occur more commonly inthe obese with a clinicopathologic entity that extends beyond uncomplicated steatosis to steatohepatitis(NASH), advanced fibrosis, liver failure and hepatocellular carcinoma. In our previous report, we showedthat racial difference between Japanese and Western people in terms of NAFLD and related liver
dysfunction. There are few reports investigating the prevalence of NASH in morbidly obese Japanese.
Methods:
Twenty-eight consecutive morbidly obese Japanese who underwent bariatric surgery in Yotsuya Medical Cubefrom October 2009 to July 2010 were enrolled. There were 16 females and 12 males (mean age: 40.3±11.2).
Mean pre-operative weight was 114.4±22.3kg and mean BMI was 41.9±6.9kg/m2. A trucut liver biopsy was
performed from left lobe of the liver at the time of surgery and analysed by a single pathologist. The
liver biopsies were assessed by applying histopathological criteria that are accepted in the pathology
literature.
Results:
Eighty-nine percent (25 in 28) of the patients undergoing bariatric surgery were found to have steatosis.
And 71.4% (20 in 28) were found to have NASH. One patient was found to have established cirrhosis.
Conclusion:
Hepatic steatosis was very prevalent in our cohort of patients presenting for bariatric surgery. The
prevalence of NASH was much higher in Japanese morbidly obese patients than the reported prevalence of
NASH in Western individuals. These findings support that Asian are more prone to central obesity and,thus, have increased risk for obesity-related comorbidities.

Background: Single Incision Laparoscopic Surgery has been expanded to bariatric surgery. Laparoscopic
Roux-en-Y gastric bypass is already accepted as one of the most effective procedure for the treatmentof type 2 diabetes mellitus. Hereby, we described our experience using SILS Port to performed Roux-en-Y
gastric bypass in nine patients with type 2 diabetes mellitus patients.Methods: After getting approvalof E-Da Institutional Review Board, 9 cases with diagnosis of Type 2 Diabetes Mellitus patients withlow body mass index (BMIless than 30) underwent Roux-en-Y gastric bypass using the SILS Port from August2010 to November 2010. Standard Roux-en-Y gastric bypass was performed with 25ml of gastric pouch, 100cm
of alimentary and biliopancreatic limb. Results: Four female and five male patients with mean BMI 27.15
and average of diabetes history of 10.2 years, underwent SILS Port Roux-en-Y gastric bypass. Novel liversuspension technique was performed in all patients. Mean operation time was 135 min. And two patientsneeded additional trocars intra-operatively, related to the difficulty in the dissection of gastric pouchand gastrojejunostomy suture. There was no surgical complication or mortality. At the first month
postoperatively, mean AC sugar dropped from 198mg/dL to 116.1mg/dL, and mean HbA1c decreased from 9.71%
to 8.18%. Conclusion: Laparoscopic Roux-en-Y Gastric Bypass with SILS Port is feasible and reproducible,
but should be performed under strict indication and by an experienced surgeon. Even in low BMI patients,
it showed high technical skill demands, increased operation time and high conversion rate.

Introduction: Diabetes is considered a life style disease. 56% diabetic patients with BMI greater than
7 are at high risk of diabetes related complications. Bariatric surgery results in diabetes resolution
in over 84% patients. Based on hindgut hypothesis suggesting role of incretins like GLP-1, early trialsof ileal interposition surgery have displayed consistent HbA1c levels below 7 in over 80% patients withover 30 kg/m2 BMI. In developing countries majority of T2DM patients are not morbidly obese and surgicalprocedures are to be evaluated for their efficacy in this group. In this study we have assessed the efficacy
of ileal transposition with sleeve gastrectomy (SGIT) in 23 to 35 BMI T2DM patients.Method: Afterinstitutional

Background:The incidence of Obesity and related metabolic disorders including Carcinoma Stomach in India
is one of the highest in the world .Hence one requires a procedure that allows postoperative surveillanceof the stomach with the best outcomes in terms of weight control and resolution of comorbidities .Here
we compare one such procedure,Duodenojejunal bypass with Sleeve against the standard Roux-en Y gastricbypass.Methods:52 patients were randomized into 2 groups of Laparoscopic Duodenojejunal bypass with
Sleeve (DJB) and Laparoscopic Roux en Y gastric bypass (RYGB) of 26 patients each. Results:The mean BMI
at the end of 6 months and 1 year was 35.16, 29.25 in RYGB and 34.51, 28.10 in DJB. The %excess BMI loss
at 6 months and 1 year were 52% ±19 and 77% ±24 in RYGB and 58% ±14 and 82% ±19 in DJB, which was
not statistically significant.14/26 patients in the RYGB and 19/26 in the DJB group had Type II
Diabetes .In RYGB

12 had complete resolution and 2 had improvement and 16 patients in the DJB had complete

resolution and remaining 3 had improvement . There was 100% resolution of Dyslipidemias in both groups.
There was 1 patient in the DJB group who presented with internal herniation 1 month post-op was managed
surgically. Conclusion:Laparoscopic Duodeno-jejunal bypass with Sleeve, which combines the principles
and advantages of Sleeve Gastrectomy and RYGB is a safe and effective alternative to gastric bypass inweight reduction and resolution of comorbidities.Also, with the possibility that the procedure can bemade less restrictive by altering the size of the sleeve, it can be employed as a procedure to treat
Metabolic Syndrome even in the lower BMI group. But, a long term follow up is necessary to establish
it as a standard procedure.

Overview of Laparoscopic Sleeve Gastrectomy (LSG).

Michel Gagner, M.D. FRCSC, FACS, FASMBS, FICS, AFC(Hon.)
Sleeve gastrectomy (SG) has been a simpler bariatric operation, which shows goodresolution of co-morbidities and provides excellent weight loss. Laparoscopic SG was
initially performed for high-risk patients (in 2000) to enable increased safety forboth operations. However, indications for SG as a primary procedure have been
increasing. The Third International Consensus Summit for SG was held in New York City,
Dec 2-4, 2010, to evaluate techniques and results.
Methods: A questionnaire was filled out at the Second ICSSG March 19-22, 2009 in Miami
Beach and compared to the recent one in NYC in 2010.
Results: Findings are based on 106 questionnaires, representing a total of 14,776 SG.
In 86.3%, SG was intended as the sole operation and 81.9% of the surgeons reported noconversions from a laparoscopic to an open SG. Mean ± SD %EWL: 1 yr 60.7 ± 15.6, 2
yrs 64.7 ± 12.9, 3 yrs 61.7 ± 11.4, 4 yrs 64.6 ± 10.5, >4 yrs 48.5 ± 8.7. Bougie
size was median 34.0 Fr., (range 16-60). The dissection commenced 5.0 ± 1.4 cm(median 5.0, range 1-10) proximal to the pylorus.
Staple-line was reinforced in
65.1%; of these, 50.9% over-sew, 42.1% buttress and 7% do both. Post-op, a high leakoccurred in 1.5% and a lower leak in 0.5%, hemorrhage in 1.1%, splenic injury in 0.1%,
and later stenosis in 0.9%. Post-op GE reflux (~3 months) was reported in 6.5% (range
0-83%). Mortality was 0.2 ± 0.9% (total 30 deaths in 14,776 patients). This year, 5
years results showed a mean of 50% EWL, a higher result than with gastric banding, but
comparisons with gastric bypass are still pending. Conclusion: SG for morbid obesity
should be recognized as a primary operation.

Rise of Sleeve gastrectomy in Asia

Muffazal Lakdawala

Abstract
Bariatric surgery is an ever evolving field. There have been several discoveries that havechanged the way bariatric procedures are carried out. This has led to a lot of enthusiasm
within the surgical community. Many of the bariatric surgical procedures have not beenable to stand the test of time and have been replaced with newer, simpler and more effective
procedures rendering the older ones obsolete.
Sleeve gastrectomy is a relatively new procedure. What was initially started as the firststage of a duodenal switch surgery in super super obese patients has now come of age tohave its place as a standalone procedure in bariatric surgery.
in the surgical community about this procedure.

There is a lot of excitement

Its popularity can be attributed to its

favourable early results. Hence surgeons from across the world are now offering it to anincreasing number of patients. The benefits of sleeve gastrectomy seem to far outweighits risks. It is a technically easier procedure with a lower learning curve. There areless chances of developing nutritional deficiencies and the remnant stomach is always
accessible for examination which is of great significance for stomach cancer endemic
countries like Japan and Korea.. Asian studies have already suggested better results interms of weight loss and resolution of co-morbidities after a sleeve gastrectomy.
Increasing proficiency of Asian surgeons in Single Incision surgery has led to further
increase in the popularity of this procedure in Asia.
The only word for caution for complete adoption of LSG is that long term results are still
awaited and leaks from staple lines are difficult to treat.

Long term results of laparoscopic sleeve gastrectomy for Korean

Gangnam CHA medical center, CHA university, Seoul, Korea

Purpose: In Asia, its types and the main causes are different from than in thewestern society. Therefore, the treatment plan should be different, and the surgery
for morbid obesity should be carefully chosen. Long term results of the isolated
laparoscopic sleeve gastrectomy which was performed for the Korean are reported.
Methods: We retrospectively reviewed 168 patients who underwent LSG from January 2003
to January 2011. One hundred thirty nine of these patients had more than 6 months offollow-up, and they are subjects of this report. Sleeve gastrectomy was performed
laparoscopicaly using Endo-GIA stapler to create a lesser curve gastric tube over a
48-Fr bougie. The longest follow up time is 8 year.
Results: Preoperative Body Mass Index (BMI) is 36.7±5.4 (30.0-59.1). The percentageof excess weight loss (%EWL) in the postoperative first, third, fifth, and seventh
year was 71.4±22.1, 66.0±29.9, 67.8±27.6, and 60.4±29.3. The percentage of excess
BMI loss (%EBMIL) was 73.1±24.3, 67.8±31.0, 73.4±32.1, and 62.2±29.7. However,the follow up rate is decreased by postoperative time. The follow up rate in thirdyear is 62.5% and fifth year is 30.2%. There was no 30-day peri-operative mortality.
Three major complications (1 delayed bleeding, 2 leakage) occurred.
Conclusion: Isolated laparoscopic sleeve gastrectomy has been an effective weightloss operation in the most of the Korean patients. However, the more follow up rate
after LSG is needed.

Sleeve Gastrectomy in Banding country.

Consultant Bariatric Surgeon St George Hospital Sydney
Dr Ken Loi MBBS Bsc(med) FRACS

Laparoscopic gastric banding has been the dominant bariatric procedure in Australia forthe last 10 years. Most bariatric surgery are performed in private hospital and there isno database to allow us to examine adequately the trend of different operations. Overall
the numbers of bariatricprocedures increased from 500 per year to 15000 last year.

However, from medicare data documented by government, we are able to estimate there isa decline in numbers of lap band performed and increase in numbers of sleeve gastrectomy.
The presentation will examine the possible reasons behind it and illustrate the problems
that will be facing australian bariatric surgeons in the next 5 to 10 years.

Laparoscopic sleeve gastrectomy in Japan

Masayuki Ohta, MD, Seigo Kitano, MD
Department of Surgery I, Oita University Faculty of Medicine, Oita 879-5593, Japan

In Japan, laparoscopic bariatric surgery was introduced in 2000, and laparoscopic sleeve
gastrectomy(LSG)

has been performed since 2005. Since

gastric cancer is afrequently-occurred disease in Japan and the excluded distal stomach after laparoscopic
Roux-en-Y gastric bypass (LRYGB) cannot be checked by usual endoscopy, LRYGB is probably
not so suitable for Japanese patients. Therefore, a number of LSG is rapidly increasing.
Japan Research Society for Endoscopic and Laparoscopic Treatments of Obesity (JELTO) which
was organized 5 years ago carried out a nationwide survey on laparoscopic bariatric surgery
in 2010. From 2000 to 2009, total 340 laparoscopic bariatric operations were performedby 9 Japanese institutes, and 102 of the operations (30%) were LSG. In 2009, 70 morbidly
obese patients underwent laparoscopic bariatric surgery, and 50 of the 70 patients (71%)
did LSG. There was no mortality and the postoperative complication rate was 7.8% in the
102 cases. Major complications were staple-line leakage in 4 cases (3.9%) andintra-abdominal bleeding (reoperation required) in 3 (2.9%). Percent excess weight loss
after LSG was 66% at 12 months and 68 % at 24 months, respectively. According to the weight
loss, 91% of patients with type 2 diabetes achieved remission, hypertension were resolvedin 62% of patients, and dyslipidemia were resolved in 53%. This survey showed the safety
and effectiveness of LSG in Japanese morbidly obese patients. In addition, LSG has been
approved as a special advanced technique in some Japanese institutes by the Ministry of
Health, Labour and Welfare since this year, which is partly covered by the government healthinsurance. Now, LSG has been rapidly spread in Japan and will play an important role intreatments for morbid obesity.

Leon Cohen1,Jon Armstrong1,Harsha Chandraratnah1

Since 2004 we have performed over 850 sleeve gastrectomies. This is a heterogenous group that includes
770 primary cases and 80 revisional sleeves.

The first 107 sleeves were calibrated against a 50fr bougie

and the next 680 against a 40 Fr bougie. We are now using a 36 Fr bougie (63)in our largest series of 618,

in most cases. Results

40 Fr primary sleeves show an excess weight loss that peaks at 18 months

at 74% and is now at 61% out to 4 years. In the earlier 50 Fr
at 24 months and had fallen to 42 %by 60 months. So far inseries the weight loss peakedat 62 %

the earlier 50 fr series 12 of the patients

have been re sleeved with their EWL returning to an average of 55 % EWL at 24 months. Only one

40 frpatient has required resleeve so far.Impact of sleeve size , surgical technique, commencement BMI, age
and sexon outcomes will be discussed.

Conclusion:
We believe that sleeve gastrectomy produces robust weight loss in the medium term providing anappropriate size bougie is selected.( no more than 40Fr)

Late weight regain is in line with the natural

history of other bariatric approaches and can be adequately managed by resleeve gastrectomy.

Po-Huang Lee, MD††

BACKGROUND: Sleeve gastrectomy has been recently proposed as a sole bariatricprocedure because of the resulting considerable weight loss in Asian morbidly obese
patients. Traditionally, laparoscopic sleeve gastrectomy requires 5-6 skin incisions
to allow for placement of multiple trocars. With the progression of scarless concept,
multiple abdominal procedures have been performed using a single incision transumbilical (SITU) incision, with good cosmetic outcomes.
METHODS: We retrospectively reviewed our patients receiving sleeve gastrectomy from
November 2008 till September 2010 .A total of 27 consecutive patients underwent
laparoscopic sleeve gastrectomy with single incision and trans-umbilical approach.
Three trocars were inserted via the umbilical incision after pneumoperitoneum.
RESULTS: Of the 27 patients, 19 were women and 8 were men, with a mean age of 32 years(range, 20-46). The mean preoperative body mass index was 35.9 kg/m (range,32.4-42.3).
The mean operative time was 70 minutes (range, 30-170). Intra-operative novel liversuspension tape was used in all patients, and no perioperative or postoperativecomplications happened. No conversion or need for adding trocar during the procedure
was found.No mortality was noted.
CONCLUSIONS: SITU laparoscopic sleeve gastrectomy is safe, technically feasible, andreproducible. Intra-operative modification of liver retraction is the key element in
improving surgical field and decreasing operation time.

Possible mechanisms of rapid improvement of glucose tolerance and insulin secretion after
laparoscopic sleeve gastrectomy (LSG)

Hiroshi Yamamoto
Departments of Surgery, Shiga University of Medical Science【Objective】 LSG has been designed as the first of a two-stage procedure for the high-risk,
super-obese patient. Recently LSG has been applied as a single-stage procedure becauseof excellent weight loss and low incidence of complications. More recently, theaccumulating data suggested that LSG produces remission or cure of type 2 diabetes mellitus(DM). To investigate the mechanism which LSG improves glucose tolerance, oral glucose
tolerance test (OGTT) was performed at preoperative and 3 months after surgery.
【Methods】 We performed LSG on two diabetic patients, one patient with impaired glucose
tolerance (IGT) and two non-diabetic patients. Plasma glucose, insulin and Glucagon-like
peptide-1 (GLP-1) levels during OGTT were measured. Fasting ghrelin levels were alsomeasured. To assess gastro-intestinal motility during OGTT, we used cine MRI.
【Results】 Diabetic patients discontinued oral hypoglycemic agent or insulin immediately
after surgery. HbA1c was improved in diabetic patients. OGTT showed that great improvementof glucose tolerance with enhancement of insulin and GLP-1 secretion in diabetic patients.
Area under the curves (AUC) for insulin and GLP-1 were increased after LSG. Fasting ghrelinlevels were decreased in all patients. Cine MRI during OGTT revealed that gastro-intestinal
motility was remarkably induced after LSG.
【Conclusion】 These results suggest that LSG can lead to rapid improvement of glucose
tolerance and insulin secretion. Increased GLP-1 secretion and decreased fasting ghrelinlevels may play a role of improvement of glucose tolerance and insulin secretion after
LSG. Induced gastro-intestinal motility during OGTT may lead to increased GLP-1 secretion
after LSG.

Background: Laparoscopic sleeve gastrectomy (LSG) is a quick and relatively simple
type of bariatric surgery which shows good resolution of co-morbidities and goodweight loss. We report on complications after LSG as a single-stage bariatric surgery
and the results of a survey on LSGs conducted by the Japan Research Society for
Endoscopic and Laparoscopic Treatments of Obesity.
Methods: Data were collected on all patients undergoing bariatric surgery between
January 2005 and December 2009, which included 340 patients from nine hospitals inJapan. We evaluated short-term morbidity in 102 patients undergoing LSG and excluded
patients undergoing LSG with duodenojejunal bypass.
Results: A total of 102 LSGs were successfully performed without conversions to an
open surgery. In 2004, there were no LSGs reported. In 2009, the mostcommonly-performed procedures were LSG (50 patients), laparoscopic gastric bypass(8), LSG with duodenojejunal bypass (8), and laparoscopic adjustable gastric banding(4). Approximately 8% of patients had perioperative complications. The most common
complications were staple line leaks (4%). Reoperation occurred in seven patients (7%),
four with bleedings and three with staple line leaks. No mortalities occurred. In oureight LSG patients, late gastric leak occurred in one patient; and it was treated with anendoscopic mucosal closure after failed attempts to treat the percutaneous abdominal
drainage.
Conclusion: The frequency of serious complications among patients undergoing LSG
was relatively low. It is a safe single-stage bariatric surgery for Japanese morbid obesity.

Is LSG perfect for Asian?
Ruby Hall Clinic, Pune, Maharastra , India
Dr. Shashank Shah
Laparoscopic Sleeve Gastrectomy(LSG) was initially introduced as a primary stage insuper obese patients to optimize their medical / anaesthesiological fitness and also
to ease the surgical technique for the index bariatric operation at a later date.
With evolving technique it has become popular stand alone procedure with provenresults of an efficient Bariatric operation in terms of effective excess weight loss ,co morbidity evolution and improvement in the quality of life. Our center has
performed more than 700 LSG till date. The longitudinal data analysis of them ispresented
at multiple
International BariatricandMetabolicconferences.
With Asian peculiarities of high adiposity, prone for type 2 diabetes, highcarbohydrate diet ,these studies have highlighted LSG with a favorable effect on
hyperglycemia ,with difficulty to monitor or treat nutritional deficiencies. Before
we call it as an ideal Bariatric operation, some facets need to be thrown light on:
like longevity of the results, recidivism etc. Long term data with the large
population and comparative studies with the existent bariatric operations is awaited.

National report of treatment of obesity and metabolic disorder from (India).
Dr. Mahendra Narwaria, MS, FICS.
President, Obesity and Metabolic Surgery Society of India
Asian Indians exhibit unique features of obesity; excess body fat,abdominal adiposity, increased subcutaneous and intra-abdominal fat, anddeposition of fat in ectopic sites (liver, muscle, etc.). Obesity is a major driver for
the widely prevalent metabolic syndrome and type 2 diabetes mellitus (T2DM) in
Asian Indians in India and those residing in other countries. Based on
percentage body fat and morbidity data, limits of normal BMI are narrower andlower in Asian Indians than in white Caucasians. A consensus statement, waspublished for revised guidelines for diagnosis of obesity, abdominal obesity, themetabolic syndrome, physical activity, and drug therapy and bariatric surgery forobesity in Asian Indians after consultations with experts from various regions ofIndia belonging to the various medical disciplines representing reputed medical
institutions, hospitals, government funded research institutions, and policy
making bodies.
According to National Family and health Survey (NFHS), approximately
7.1% of Indian population is under obesity risk. Almost 65% of adult urban
Indian are –either over weight, obese or have abdominal obesity. The highest
incidence is observed in North western (Punjab) part of India (M: F- 30.3/37.5%),
followed by South (M: F-24.3/34%) and North east (M: F-17.3/21%).
With an estimated 50.8 million people living with diabetes, India has theworld’s largest diabetes population, followed by china with 43.2 million. The
prevalence of type II DM in adult population ranges from 9% to 16%, with 14.2 %of male and17.5 of female.
The Obesity and Metabolic Surgery Society of India was established in 2001.
The indication for surgery is generally in accordance with guidelines using the
WHO standard for obesity on Asia, i.e. BMI >37.5/32.5 with co-morbidities. There
are few no of bariatric and metabolic surgeries carried out outside the standard
guidelines for obesity surgery but they are mainly as part of some clinical trials.
There are about 80 surgeons (certified general, GI surgeons with training
and experience) performing bariatric surgery regularly in India, carrying out
2000 procedures per year.
There are 5 high volume centres and few of them applied for centre of
excellence (ICE) certification from ASMBS.OSSI is jointly working with SRC todevelop centre of excellence in India. Cost of bariatric treatment depends uponthe types and location of the operative procedure. We accept and operate theinternational patients.

Current status of Bariatric surgery in Korea
Dr. Lee’s Bariatric Surgery Center in Seoul, Korea(The Korean Metabolic and Bariatric Surgery Society)
Hongchan Lee, M.D., Ph.D

Obesity is not only a health problem in western countries, but also in Korea. According to2009 Korean National Health & Nutrition Examination Survey(KNHANES), prevalence of obesityin adults was 32.4% which is a big change over the last 10 yeas. More alarming is the
problem of children and adolescent. From 2003 to 2009, number of bariatric procedures wasincreased in 622%.
All surgeries were performed through laparoscopic procedures. 63.3% adjustable gastricbandings, 12.6% gastric sleeve resections, 5.9% VBGs(with or without sleeve resection)
were the restrictive operations performed. 12.0% Roux-en-Y gastric bypass, 12.6% Minigastric bypass, 2.6% Duodeno-jejunal Bypass were the malabsorptive(both restrictive)
procedures since 2003.
Based on the statistics, the surgeon were performed in most hospitals when the BMI wasover 35kg/m2 while more than 2 significant obesity related co-morbidities were found withBMI over 30kg/m2. Currently the bariatric surgery in Korea is still at a developing level,
and has not been performed very much compared with the number of patients who need it.
As the bariatric surgery will gain more important as the number of obesity people
increases every day, physicians need to make more efforts to help the public to havecorrect understanding about the bariatric surgery. Insurance coverage is another concern
in my country because bariatric surgery is not covered by National Health Insurance in
Korea. So, it became an expensive surgery, not accessible for everybody. As obese people
are often from middle to lower socioeconomic class, access to surgery is very limited. As
these people are in need, we have to raise our voice about reimbursement for bariatricpatients.

BARIATRIC & METABOLIC SURGERY in the Philippines
President, Philippine Society for Metabolic and Bariatric Surgery
Hildegardes C. Dineros, MD, FPCS FACS
Third world countries like the Philippines was not immune to the epidemic of Obesity,with a progressively rising prevalence, one in four being overweight and one out oftwenty is obese. Roughly, there are 4 million obese Filipinos and close to a million
are morbidly obese. Of about 90 million population, the extrapolated prevalence ofDiabetes is 5 million, more than 90% of which belong to Type 2 category.
The Philippine experience in Bariatric Surgery started in 2001 as VBG. The following
year, Open Gastric Bypass was performed and 5 years later, Laparoscopic techniques
were done for RYGBP, Gastric Banding, BPD-DS, and Sleeve Gastrectomy. Class II Obesity,
defined as BMI 30kg/m2 was the baseline criterion for weight loss surgery since atthis level, co-morbid conditions are already observed.
The Philippine Society for Metabolic and Bariatric Surgery was established in 2007,
composed of about 25 surgeon members, half of which are doing bariatric surgicalprocedures already, and majority doing mostly Gastric Banding. Certified General
Surgeons with training and experience in laparoscopic bariatric surgery, have up to
the present, performed close to 600 bariatric operations. Surgery for Non-obese Type 2
Diabetes was first done in 2008using LSG with Loop DJB.

National report from Hong Kong

Wilfred Mui
Hong Kong Bariatric and Metabolic Institute

Bariatric surgery is a new specialty in Hong Kong and it is growing from its infancy
stage. It was introduced in Hong Kong in 2001 and the development was very rapid in thepast ten years. Bariatric procedure in Hong Kong is evolving from a single surgicalprocedure (gastric banding) to the full package of both endoscopic and laparoscopic
surgeries. The primary procedures in Hong Kong at the moment are restrictive procedures(intragastric balloon, gastric banding, sleeve gastrectomy and sleeve plication),whereas malabsorptive procedures (mini-gastric bypass and sleeve gastrectomy with DJB)
are reserved as second-line therapy. Initially, we encountered difficulties in
persuading patients and even doctors in accepting such an invasive treatment for obesity.
Now, more and more physicians and patients understand the importance of weight control
in severe obesity and agree that the beneficial effect of surgery seems out-weighted
its risk in selective group of patients. We will report the development of this specialty
in Hong Kong.

National Report from Malaysia
Professor Dr Chin Kin Fah (Presenter), Dr Pok Eng Hong
Department of Surgery, Faculty of Medicine, University Malaya, Kuala Lumpur, Malaysia.
In Malaysia, a developing country, the increasing prevalence of obesity and associatedmetabolic syndrome has created major healthcare problem due to the adoption of morewesternized lifestyle and diet. Population surveys have found the prevalence of obesity has
rapidly increased 3 folds in recent decade. The National Health & Morbidity Study in 1996 and2006 revealed that the prevalence of overweight (BMI 25-30) rose from 16.6% to 29.1%. The
prevalence of obesity (BMI>30) increased from 4.4% to 14%. It was also showed our female
population, ethnicity of Indian & Malay and house wife tend to be obese. It was noted theprevalence of diabetes mellitus in this population also increased from 8.3% to 14.9% with
substantially portion of them undiagnosed. There is an estimated about 1.5 million diabetes
patient (5.7%) which is a significant healthcare burden in Malaysia with a small populationof about 26 million people in 2006. Although the bariatric surgery has been prove to be costeffective treatment of obesity and associated co-morbidity especially DM, the adoption ofthis advanced surgery is still slow in Malaysia. Currently, only hospitals with qualified andexperienced laparoscopic surgeon are routinely offering this procedure. The lack of surgicaltraining opportunity, public awareness and no insurance coverage for obesity might be thefactors that hinder the progress of this surgery. Lastly, we foresee, with the risingprevalence of T2DM affecting younger age group and the promising effectiveness of bariatricsurgery as a form of metabolic procedure, the most cost effective therapy for early obese
T2DM should be surgery, as a first line modality in future.

National Report on Bariatric Surgery from Japan

Department of Weight Loss Surgery, Yotsuya Medical Cube, Tokyo, Japan
Kazunori Kasama MD, FACS

Obesity among adults is defined as a BMI of 25 or higher in Japan. The obesity prevalence(BMI ≧ 25) has increased to 28.6% in male and 20.6% in female over the past decade. Obesity
prevalence (BMI ≧ 30) is 3.2%.
The prevalence of diabetes mellitus with HbA1c >6.5 or under treatment has increased from
6.9 million in 1997 to 8.9 million in 2007.
Recently, one of our bariatric societies (Japanese Society for Surgery of Obesity andMetabolic disorders) has announced a statement on BMI criteria for bariatric surgery inJapan. The criteria recommends bariatric surgery for people who have BMI ≧ 35 or BMI ≧32 with obesity-related comorbidities. But bariatric surgery for people with BMI between
32 to 35 remained to be positioned on a clinical trial.
From 2000 to 2009, totally, 340 laparoscopic bariatric procedures were performed in 9
institutes. The most popular procedure was laparoscopic Roux-en-Y gastric bypass (LRYGB,
n=147), then the second one was laparoscopic sleeve gastrectomy (LSG, n=102) and the third
one laparoscopic adjustable gastric banding (LAGB, n=55). However, the number of LRYGB
has decreased and in contrast, the number of LSG has rapidly increased.
The medical cost of bariatric surgery is approximately 10.000-20.000 dollars. It depends
on the types of procedures.
There are several problems to prevent and treat obesity. Modern lifestyle and foods areout of alignment with true health. Nation’s recognition of obesity is an obstacle tocivilization and enlightenment of bariatric surgery in Japan.
In conclusion, we are still ill-equipped to deal with the crisis of obesity and diabetes
mellitus. It is essential to establish the international network in APC for developmentin this field.

National report on surgical treatment of obesity and metabolic disorder in Singapore
KTP Hospital Singapore
Dr Anton Cheng
According to the Singapore National Health Survey 2004, obesity rate ( BMI > 30) in Singapore
was 7.3% in female and 6.4% in male. Among the three major racial groups in Singapore, 4.2%of Chinese, 19.3% of Malays and 13.4% if Indians are obese. In 2004, 8.2% of the population
was diabetic , with 8.9% of male and 7.6% of female. The latest unpublished data showedobesity rate has gone to 10.8% of the population in the 2010 National Health Survey, With the
Malay population showing 25% obesity. DM rate however, has not changed over the last 12
years.
The Obesity and Metabolic Surgery Society of Singapore is registered as of January 2011. A
national database is being set up. Indication for surgery is generally in accordance with theSingapore Ministry if Health guidelines using the WHO standard for obesity on Asia, i.e. BMI> 37.5 or BMI > 32.5 with obesity associated co-morbidities. There is no metabolic surgery
carried out outside the standard guidelines for obesity surgery.
There are about 10 surgeons performing bariatric surgery regularly in Singapore, carrying out
about 200 procedures per year. 80% of these, divided equally, are sleeve gastrectomies andgastric bands. There are smaller numbers of bypass and other procedures.
There is no certified center of excellence in Bariatric surgery in Singapore. Cost varies
according to where these procedures are carried out. A lot of those performed in government
hospitals are heavily subsidised.

Slide-1*Approximately 66% of whole Turkish population is under obesity risk.
*The incidence of obesity is 24% for males and 31% for females.
*The highest incidence is observed in Southeastern part of Turkey (61%), followed by
mid-Anatolia (55%), Northern west (50%), and West parts (15%)*The percentage of normal weight adults is 13.6% in females and 20% males.
*The incidence of overweight children is 24% for females and 31% for males.

prevalence reaches 30%.

Slide-3*We have a national bariatric and metabolic surgery society in Turkey.
*I perform both metabolic and bariatric surgery.
*For bariatric surgery purposes my indication is BMI over 40*For patients with T2 Diabetes or Metabolic Syndrome, BMI (unless over 20) is not alimitation in my surgical practice.

Slide-4*The annual number of bariatric operations is estimated to be around 500 cases.
*I performed 76 operations within 2 years on my own (7.6%).
Slide-5*There are no specified or certified bariatric surgeons in Turkey.

Slide-6*There is no nationwide database for sharing the pre- and post-operative data of bariatricsurgery.

Slide-7*The average cost for bariatric surgery in Turkey varies between 5000 and 20000 USD,
depending on the type and location of the operative procedure.
*The government only pays 30-40% of the bill if the patient obtains a multidisciplinary
council approval. (The council mainly consists of endocrinologists!)

Slide-8*For patients with T2DM, I operate on all patients with a BMI above 20, if they meet the
metabolic criteria for the operation.
*I did 4 revision bariatric surgeries. (1 anastomotic stricture, two band removals with
sleeve and one band removal with BIB).
*I work at a private university and its private hospitals in Istanbul. We accept and operate
on overseas patients.

Slide-9*The main problem, also affecting my country from obesity pandemic is the so called“Coca-colonization”, which refers to global standardization of refined or saccharified
food.
*From my (surgical) aspect, the main problem is internists and endocrinologists who aretrying to discover America once again.
*The main need is education and social awareness.

Slide-10*Protection is more important than treatment. I personally believe that we should worldwide
keep away from refined and saccharified food. However, these products are easy to keep,
suitable for overseas transport and unfortunately, they are tasty.

*Each government should establish their policy for nationwide food supplies andconsumption of childhood food products.
*Turkish people like to eat bread with spaghetti and/or rice. I think that we should atfirst educate people, than we should raise a social awareness about the global food industry,metabolic syndrome and the importance of physical exercise.
*For those with already settled metabolic syndrome, the importance and affectivity ofsurgical treatment should be emphasized, with particular notation on the advantages oflaparoscopic surgery.

Slide 11
*From bariatric point of view, the importance of a team work has always been emphasized.
I have recently moved to a new institute in Istanbul and am trying to settle my own team.
*From metabolic point of view, I operate on T2DM patients with end-organ damage. I haveoperated on 46 non-obese, overweight or type 1 obese (BMI=30-35) patients with T2DM. I
believe that we should also emphasize and try to produce a global awareness for surgicaltreatment of Diabetes.

National report
Bariatric surgery in Brazil: Current status
Joel Faintuch , Francisco Karkow,
Fernanda Pezzi (Sao Paulo University Medical
School and Fatima Faculty, Caxias do Sul)
Introduction
Obesity is a growing epidemic not only in industrialized countries but also inthe developing world. The main difference in places like Brazil is the phenomenon ofnutrition transition. Till the recent past undernutrition was the main problem. The
rapid shift toward excessive body weight resulted in the relatively frequentcoexistence, in the same family and in the same house, of examples of the two
derangements, namely undernourished children with obese parents, or the opposite
association.
Antiobesity procedures were started in this country in the 1970´s, in the formof jejunoileal bypass. Multiple modalities were tested along the years, especially in
Hospital das Clinicas, Sao Paulo, which was the pioneer institution, till thecreation of the Brazilian Society of Bariatric and Metabolic Society (BSBMS) in 1999,
by Artur Garrido Jr.
Yearly congresses have been organized since that time, and the Society counts
more than 900 members including surgeons as well as allied health professionals.
Current president is Ricardo Cohen. A Bulletin was created in 2000 by Joel Faintuch
and Artur Garrido Jr and converted into a quarterly Journal five years later. Now the
Journal has merged with the Brazilian Archives of Digestive Surgery, which also
appears every three months.
Acceptance of the specialty
Until the early 1990´s just a few dozen surgeons had interest in bariatric
operations and very few surgical residents had exposure to such the techniques.
However after the establishment of BSBMS growth has been exponential, notably after
government and private health providers accepted reimbursing the operations. At thismoment such procedures are very well established all over the country, and actively
sought by obese patients. Indeed, public hospital often suffer with long waiting
lines.
Surgical residents in large academic hospitals and also in certain private
ones have the chance of operating bariatric candidates during their rotations, and acouple of Centers of Excellence in Bariatric Surgery has been created in Sao Paulo,with a tendency to grow towards other cities as well.
Surgical procedures
The most practiced modality in the country is the Roux-en-Y gastric bypass(RYGB), which is the first intervention recognized and funded by the Federal Social
Security System. Approximately 75% of the candidates undergo this treatment, burmultiple other options are endorsed by BSBMS, namely vertical banded gastroplasty,
sleeve gastrectomy, gastric banding, Scopinaro procedure and duodenal switch, alongwith the endoscopically placed intragastric balloon.
Patient care and hospital facilities
A national consensus signed by six surgical and clinical professional societies
in 2007 established directives for most routines and indications concerning bariatricinterventions, from patient selection to hospital equipment and postoperative care.
Current statistics
Brazil has roughly 190 million inhabitants of which between 2 and 4 million are
morbidly obese, depending on the estimate. About 30 000 bariatric procedures are
conducted each year, of which 25-300 % are payed by the Federal Social Security
System, 60-70% by commercial Health Providers, and around 5 % privately financed.

Distribution of morbid obesity
A national survey under the initiative of BSBMS revealed that though morbid
obesity doesn´t spare any of the regions of Brazil, distribution is not homogeneous.
The two poorest areas, namely the North and Northeast, display the lowest proportion(2%). The rich Southeastern region, which includes Sao Paulo, wasn´t bad either with
2.5% prevalence. The highest rates corresponded to the Western region and to theSouth, both with 5% values.
As concerns the South there is a rather obvious explanation. This area is quite
affordable, there is strong immigrant influence especially from Italian and German
people, and the population appreciates hearty meals. The Western region was asurprise and no obvious explanation is available, though meat is particularly
abundant in that area because of vast cattle-raising farms.
Metabolic surgery
In the last five years several groups have engaged in standard bariatric or
tailor-made operations for non-morbidly-obese diabetics, with variable results.
Animal investigations were atarted
in a number of University laboratories, andMaster´s as well as PhD theses are going on . Some controversy occurred when acouple of teams started performing such interventions on a routine basis. A consensus
established in 2009 decided that these treatments are still experimental and should
be conducted under approval of an Ethical Committee, for the purposes of scientificinvestigation only.
