“…However, while intraoperative adverse events are known to increase the risk for postoperative complications (17,18), these intraoperative adverse events are by nature often addressed during the operation and no increase in postoperative complication rates was seen. The results of the present study supports the results of a previous study reporting that division of the omentum can be considered to be both feasible and safe during LRYGB (19).…”

“…LRYGB, regarded as the gold standard of bariatric surgery, was introduced into Taiwan in 2000 (13) and has subsequently proven to be a more effective but complicated bariatric surgery than LVBG (23). Recently, LRYGB has also been developed in Japan, Korea, the Philippines, Malaysia and China (13,(33)(34)(35)(36)(37). Another simplified gastric bypass, LMGB, first reported by Rutledge, was also introduced into Taiwan in 2001 (17).…”

Objective: Obesity surgery is the most effective treatment for morbid obesity and leads to dramatic improvement in related co-morbidities. The aim of this study was to present the long-term results of a prospective trial studying the efficacy of laparoscopic obesity surgery in a group of oriental patients. patients who underwent obesity surgery in a single bariatric center in Asia were recruited. Various procedures have been adopted so far, including laparoscopic vertical banded gastric partition in 652 patients (27.3%), laparoscopic gastric bypass (LGB) in 1228 patients (51.5%), laparoscopic adjustable gastric banding in 226 patients (9.5%), laparoscopic sleeve gastrectomy in 128 patients (5.4%), gastric balloon in 68 patients (2.8%) and laparoscopic revision surgery in 83 patients (3.5%). We evaluated the clinical data and effect of obesity surgery on different procedures. Results: Overall, the major complication rate and mortality were 1.5% and 0.12%. There was an increase of surgical risk in laparoscopic sleeve gastrectomy and laparoscopic revision surgery patients. The mean total weight loss for the population was 28.1%, 33.9%, 21.3% 18.7% and 17.4% at 1, 3, 5, 7 and 9 years after surgery, respectively. LGB had a better weight loss (30.1%) than that of the restrictive-type procedures (20.9%) at 5 years after surgery. After surgery, most of the obesity-associated co-morbidities were resolved or improved in these patients. Conclusion: Laparoscopic obesity surgery resulted in significant and sustained weight loss in morbidly obese Asian patients with resolution of associated comorbidities.LGB had a better result in weight reduction than other restrictive procedures.

“…Antecolic antegastric placement of the alimentary limb for the gastro-jejunal (GJ) anastomosis with RYGB has been advocated to reduce the rates of internal hernia and shorten operative time and has been the preferred technique by most [ 2 ]. One common technical step to facilitate antecolic antegastric placement of the alimentary limb and possibly reduce tension at the GJ is division of the greater omentum [ 3 ]. While it is a relatively easy maneuver, omental infarction and necrosis have been reported as a complication leading to the need for additional interventions and a protracted recovery.…”

Omental infarction is a rare phenomenon that can be idiopathic or secondary to a surgical intervention. Greater omentum division has been advocated to decrease tension at the gastro-jejunal anastomosis during laparoscopic Roux-en-Y gastric bypass (RYGB). We report a case of omental infraction complicated by liquefied infected necrosis presenting 3 weeks after antecolic antegastric RYGB. The patient underwent laparotomy and subtotal omentectomy with a protracted hospital course due to intra-abdominal abscesses, acute kidney injury and small bowel obstruction that were successfully managed non-operatively. We reviewed the available literature on omental infarction after RYGB, focusing on associated symptoms, possible etiology, timing of presentation, management and propose an alternative technique without omental division.
