title: NECROTIZING PANCREATITIS: DESCRIPTION OF VIDEOSCOPIC ASSISTED RETROPERITONEAL DEBRIDEMENT (VARD) TECHNIQUE WITH COVERED METALLIC STENT

description: ABSTRACT Background : Acute pancreatitis is the third most common gastrointestinal disorder requiring hospitalization in the United States, with annual costs exceeding $2 billions. Severe necrotizing pancreatitis is a life-threatening complication developed in approximately 20% of patients. Its mortality rate range from 15% in patients with sterile necrosis to up 30% in case of infected one associated with multi-organ failure. Less invasive treatment techniques are increasingly being used. These techniques can be performed in a so-called step-up approach. Aim: To present the technique for videoscopic assisted retroperitoneal debridement (Vard technique) with covered metallic stent in necrotizing pancreatitis. Method: A guide wire was inserted through the previous catheter that was removed in the next step. Afterwards, the tract was dilated over the guide wire. Then, a partially covered metallic stent was deployed. A 30 degrees laparoscopic camera was inserted and the necrosis removed with forceps through the expanded stent under direct vision. Finally, the stent was removed and a new catheter left in place. Result : This technique was used in a 31-year-old man with acute pain in the upper abdomen and diagnosed as acute biliary pancreatitis with infected necrosis. He was treated with percutaneous drains at weeks 3, 6 and 8. Due to partial recovery, a left lateral VARD was performed (incomplete by fixed and adherent tissue) at 8th week. As the patient´s inflammatory response was reactivated, a second VARD attempt was performed in three weeks later. Afterwards, patient showed complete clinical and imaging resolution. Conclusions : Videoassisted retroperitoneal necrosectomy using partially covered metallic stent is a feasible technique for necrotizing pancreatitis.

title: POSTOPERATIVE CHANGES IN INTESTINAL MICROBIOTA AND USE OF PROBIOTICS IN ROUX-EN-Y GASTRIC BYPASS AND SLEEVE VERTICAL GASTRECTOMY: AN INTEGRATIVE REVIEW

description: ABSTRACT Introduction: Studies suggest that weight loss induced by bariatric surgery and the remission of some comorbidities may be related to changes in the microbiota profile of individuals undergoing this procedure. In addition, there is evidence that manipulation of the intestinal microbiota may prove to be a therapeutic approach against obesity and metabolic diseases. Objective: To verify the changes that occur in the intestinal microbiota of patients undergoing bariatric surgery, and the impact of the usage of probiotics in this population. Methods: Articles published between 2007 and 2017 were searched in Medline, Lilacs and Pubmed with the headings: bariatric surgery, microbiota, microbiome and probiotics, in Portuguese, English and Spanish. Of the 166 articles found, only those studies in adults subjected to either Roux-en-Y gastric bypass or sleeve vertical gastrectomy published in original articles were enrolled. In the end, five studies on the change of intestinal microbiota composition, four on the indirect effects of those changes and three on the probiotics administration on this population were enrolled and characterized. Conclusion: Bariatric surgery provides changes in intestinal microbiota, with a relative increase of the Bacteroidetes and Proteobacteria phyla and reduction of Firmicutes. This is possibly due to changes in the gastro-intestinal flux, coupled with a reduction in acidity, in addition to changes in eating habits. The usage of probiotics seems to reduce the gastro-intestinal symptoms in the post-surgery, favor the increase of vitamin B12 synthesis, as well as potentiate weight loss.

title: EARLY ORAL FEEDING POST-UPPER GASTROINTESTINAL TRACT RESECTION AND PRIMARY ANASTOMOSIS IN ONCOLOGY

description: ABSTRACT Background: The practice of starving patients in the immediate period after upper gastrointestinal surgery is widespread. Early oral intake has been shown to be feasible and may result in faster recovery and decrease length of hospital. Aim: To evaluate the feasibility and safety of oral nutrition on postoperative early feeding after upper gastrointestinal surgeries. Methods: Observational cohort design study with convenience retrospective data in both genders, over 18 years, undergoing to total gastrectomy and/or elective esophagectomy. They have received oral or enteral nutrition in less than 48 h after surgery, and among those who started with enteral nutrition, the oral feeding up to seven days. Results: The study was performed in 161 patients, 24 (14.9%) submitted to esophagectomy, 132 (82%) to total gastrectomy and five (3.1%) to esophagogastrectomy. Was observed good dietary acceptance and low percentage (29%) of gastrointestinal intolerances, more pronounced among those with enteral diet. Most of the patients did not present postoperative complications, 11 (6.8%) were reopened, five (3.1%) had fistulas, three (1.9%) wound dehiscence, three (1.9%) fistula more wound dehiscence and six (3.7%) other non-infectious complications. Conclusion: Early oral diet is safe and viable for patients undergoing upper gastrointestinal surgery.

title: THE CRITICAL VIEW OF SAFETY PREVENTS THE APPEARANCE OF BILIARY INJURIES? ANALYSIS OF A SURVEY

description: ABSTRACT Background: The risk of bile duct injury (BDI) during cholecystectomy remains a concern, despite efforts proposed for increasing safety. The Critical View of Safety (CVS) has been adopted promoting to reduce its risk. Aim: To perform a survey to assess the awareness of the CVS, estimating the proportion of surgeons that correctly identified its elements and its relationship with BDI. Methods: An anonymous online survey was sent to 2096 surgeons inquiring on their common practices during cholecystectomy and their knowledge of the CVS. Results: A total of 446 surgeons responded the survey (21%). The percentage of surgeons that correctly identified the elements of CVS was 21.8% and 24.8% among surgeons claiming to know the CVS. The percentage of surgeons that reported BDI was higher among those that incorrectly identified the elements of the CVS (p=0.03). In the multivariate analysis, career length was the most significant factor related to BDI (p=0.002). Conclusions: The percentage of surgeons that correctly identified the Critical View of Safety was low, even among those who claimed to know the CVS. The percentage of surgeons that reported BDI was higher among those that incorrectly identified the elements of the CVS.

title: SUBCUTANEOUS ONLAY LAPAROSCOPIC APPROACH (SCOLA) FOR VENTRAL HERNIA AND RECTUS ABDOMINIS DIASTASIS REPAIR: TECHNICAL DESCRIPTION AND INITIAL RESULTS

description: ABSTRACT Background: Diastasis of the rectus abdominis muscles (DMRA) is frequent and may be associated with abdominal wall hernias. For patients with redudant skin, dermolipectomy and plication of the diastasis is the most commonly used procedure. However, there is a significant group of patients who do not require skin resection or do not want large incisions. Aim: To describe a “new” technique (subcutaneous onlay laparoscopic approach - SCOLA) for the correction of ventral hernias combined with the DMRA plication and to report the initial results of a case series. Method: SCOLA was applied in 48 patients to correct ventral hernia concomitant to plication of DMRA by pre-aponeurotic endoscopic technique. Results: The mean operative time was 93.5 min. There were no intra-operative complications and no conversion. Seroma was the most frequent complication (n=13, 27%). Only one (2%) had surgical wound infection. After a median follow-up of eight months (2-19), only one (2%) patient presented recurrence of DMRA and one (2%) subcutaneous tissue retraction/fibrosis. Forty-five (93.7%) patients reported being satisfied with outcome. Conclusion: The SCOLA technique is a safe, reproducible and effective alternative for patients with abdominal wall hernia associated with DMRA.

title: INGUINAL REPAIR VIA ROBOTIC ASSISTED TECHNIQUE: LITERATURE REVIEW

description: ABSTRACT Introduction: Inguinal hernia is one of the most frequent surgical diseases. Currently, with the advantages of minimally invasive surgery, new questions arise: what will be the best approach for correction of inguinal hernia? Is there real benefit to the robotic approach? Objective: To compile results of the published studies that used the robot-assisted technique in the repair of inguinal hernia, analyzing its limitations, complications and comparing it with those of the pre-existing techniques. Method: The review was performed from the Medline database with the following descriptors: (inguinal hernia repair OR hernioplasty OR hernia) AND (robot OR robotic OR robotic assisted) being retrieved 391 articles. After verification of the titles and abstracts, we identified eight series of cases congruent with the objectives of this review. Three reviewers participated in the extraction and selection of results. Results: Comparative studies showed an increase in surgical time in relation to the open and videolaparoscopic approach. The complications present similar rates with the other repair routes. Conclusion: This technique has been shown to be effective for the correction of inguinal hernia, but the benefits of using robotic surgery are unclear. So, there is a need for randomized studies comparing laparoscopic to robotic repair

title: ANATOMICAL VARIATIONS OF THE CELIAC TRUNK: A SYSTEMATIC REVIEW

description: ABSTRACT Introduction: The celiac trunk (CT) is one of the abdominal portion branches of the aortic artery and, together with the superior mesenteric and inferior mesenteric arteries, participates in the abdominal viscera vascularization through a series of anastomoses. Absence of CT or variation in the number of terminal branches implies in varied abdominal arteries origins, which may have implication in surgical approaches. Objective: To analyze the anatomical variations of the celiac trunk and possible associated surgical clinical implications. Methods: It is a systematic review of articles indexed in the PubMed, Lilacs, SciELO, Springerlink, Scienc Direct and Latindex databases from August to September 2017. Original articles involving the anatomical variations of the celiac trunk in humans were included. The presence/absence of the celiac trunk, the number of terminal branches and the place of origin of its branches in variant cases of the normal anatomical pattern, were considered for this study. Results: At the end of the research, 12 articles were selected, characterized by sample, anatomical structure evaluation method and main results. The normal anatomical pattern was the most prevalent in most studies (75.0%). CT was absent in 41.7% of the findings. The most prevalent anatomical variation was the presence of CT with bifurcation (66.7%). It was also observed the origin of the common and splenic hepatic arteries from the mesenteric arteries (25.0%). The presence of only one branch (16.7%) and quadrifurcation (8.33%) were other findings. Conclusion: CT variations are not uncommon findings, with different anatomic variants being reported. Thus, the importance of knowing the possible variations of this structure is emphasized, which may have implications for surgical interventions and imaging studies related to the abdominal region.

title: IMPACT OF MELD SODIUM ON LIVER TRANSPLANTATION WAITING LIST

description: ABSTRACT Background: Serum sodium was incorporated to MELD score for the allocation of liver transplantation In the USA in 2016. Hyponatremia significantly increased the efficacy of the score to predict mortality on the waiting list. Such modification was not adopted in Brazil. Aim: To carry out a simulation using MELD-Na as waiting list ordering criteria in the state of Paraná and to compare to the list ordered according to MELD score. Methods: The study used data of 122 patients waiting for hepatic transplantation and listed at Parana´s Transplantation Central. Two classificatory lists were set up, one with MELD, the current qualifying criteria, and another with MELD-Na. We analyzed the changes on classification comparing these two lists. Results: Among all patients, 95.1% of the participants changed position, 30.3% showed improvement, 64.8% presented worsening and 4.9% maintained their position. There were 19 patients with hyponatremia, of whom 94.7% presented a change of position, and in all of them there was an improvement of position. One hundred and one patients presented sodium within the normal range and 95% of them presented a change of position: Improved placement was observed in 18.8%, and worsened placement in 76.2%. Two patients presented hypernatremia and changed their position, both worsening the placement. There was a significant different behavior on waiting list according to sodium serum level when MELD-Na was applied. Conclusion: The inclusion of serum sodium caused a great impact in the classification, bringing benefit to patients with hyponatremia.

title: LAPAROSCOPIC DISTAL PANCREATECTOMY WITH OR WITHOUT SPLEEN PRESERVATION: COMPARATIVE ANALYSIS OF SHORT AND LONG-TERM OUTCOMES

description: ABSTRACT Background: Laparoscopic distal pancreatectomy (LDP) is the preferred approach for resection of tumors in the distal pancreas because of its many advantages over the open approach. Aim: To analyse and compare short and long-term outcomes from LDP performed through two different techniques: with splenectomy vs. spleen preservation and splenic vessel preservation. Method: Fifty-eight patients were operated and subsequently divided between two groups: Group 1, LDP with splenectomy (LDPS); and Group 2, LDP with spleen preservation and preservation of splenic vessels (LDPSPPSV). Results: The epidemiological characteristics were statistically similar between the two groups (age, gender, BMI and lesion size). Both the mean of operative time (p=0.04) and the mean of intra-operative blood loss (p=0,03) were higher in Group 1. The mean of resected lymph nodes was also higher in Group 1 (p&lt;0.000). There were no statistic differences between the groups in relation to open conversion, morbidity or early postoperative mortality. The mean hospital stay was similar between groups. Pancreatic fistula (grade B and C) was similar between the groups. The mean of overall follow-up was 37.6 months (5-96). Late complications were similar between the groups. Conclusion: Both techniques were superimposable; however, LDPS presented, respectively, higher intra-operative bleeding, longer duration of the operation and higher number of lymph nodes resected. No differences were observed in the studied period in relation to the appearance of infections or neoplasm related to splenectomy during follow-up. Maintenance of the spleen avoided periodic immunizations in patients in LDPSPSV. It is indicated in small pancreatic lesions with indolent course.
