Bariatric surgery appears efficacious compared to st and ard care in reducing BMI .
Weight losses are greatest with diversionary procedures , intermediate with diversionary/restrictive procedures , and lowest with those that are purely restrictive .
Compared with Roux-en-Y gastric bypass , adjustable gastric b and ing has lower weight loss efficacy , but also leads to fewer serious adverse effects
A pilot study of long-term effects of a novel obesity treatment: omentectomy in connection with adjustable gastric banding
AIM : To determine whether visceral fat reduction in connection with bariatric surgery could improve weight loss and metabolic profile of obese subjects . PATIENTS AND METHODS : In a one-center , r and omized and controlled pilot trial we assigned 50 subjects with severe obesity ( body mass index > 35 kg/m2 ) to either adjustable gastric b and ing ( AGB ) alone ( 11 men and 14 women ) , or AGB plus surgical removal of the total greater omentum ( 11 men and 14 women ) . The patients were followed at regular intervals for 2 y and examined at 0 and 24 months with respect to body composition and metabolic profile . RESULTS : No significant differences between control and omentectomized patients were observed at baseline . The removed greater omentum constituted 0.8±0.4 % ( mean±s.d . ) of total body fat . At 2 y follow-up there was an expected decrease in body weight and an improvement in metabolic profile in both groups . Although omentectomized subjects tended to lose more weight than control subjects the difference was not statistically significant and changes in waist-to-hip ratio and saggital diameter did not differ between groups . However , the improvements in oral glucose tolerance , insulin sensitivity and fasting plasma glucose and insulin were 2–3 times greater in omentectomized as compared to control subjects ( P from 0.009 to 0.04 ) , which was statistically independent of the loss in body mass index . No differences in blood lipids between the groups were recorded . No adverse effects related to omentectomy were observed . CONCLUSIONS : Omentectomy , when performed together with AGB , has significant positive and long-term effects on the glucose and insulin metabolic profiles in obese subjects
