Laparoscopic sleeve gastrectomy (LSG) is currently the most frequent primary bariatric procedure performed worldwide. LSG is safe and effective in terms of excess weight loss. It is a powerful metabolic operation that activates significant hormonal pathways that lead to changes in eating behaviour, glycemic control and intestinal functions. LSG is easier regarding its technical aspects and does not need any intestinal anastomosis, begin limited to the stomach. The most frequent and sometimes dangerous complications are leaking, haemorrhage, splenic injury, sleeve stenosis and gastroesophageal reflux. Despite its established efficacy and safety, controversy still exists on optimal operative technique for LSG: bougie size, the distance of resection margin from the pylorus, the shape of the section at the gastroesophageal junction, staple line reinforcement and intraoperative leak testing is among the most controversial issues 11. In literature, different authors have adopted a resection distance from the pylorus between 2 and 6-7 cm with various reasons 11. Resections more distant to the pylorus improve gastric emptying, prevent distal stenosis and reduce intraluminal pressure, potentially leading to a lower incidence of fistula and/or reflux. On the other hand, resections close to the pylorus would reduce gastric distensibility and increase intragastric pressure, potentially increasing satiety with less oral intake 11(11,12). The primary aim of this randomized monocentric study is to evaluate %EWL at 1 and 2 years follow-up after LSG in two Groups: Group A with a gastric resection starting from 2 cm from the pylorus with therefore a wide antrectomy and Group B with a gastric resection starting from 6 cm from the pylorus with therefore a small antrectomy.

Laparoscopic sleeve gastrectomy (LSG) restricts gastric volume to achieve weight loss. We aimed to compare the efficacy of LSG with and without antrectomy for achieving weight loss.
Bariatric surgery predisposes patients to cholelithiasis and therefore the need of a subsequent cholecystectomy; however, the incidence of cholecystectomy after bariatric surgery is debated.
Weight loss after bariatric surgery yields important health benefits. A multitude of observational studies have investigated the association of bariatric surgery for severe obesity with the risk of ca...
Outcomes after bariatric surgery are tied to surgical volume; however, this relationship is not clearly established for each procedure.
Although the number of weight loss procedures is increasing, bariatric surgery is not used equitably in the United States. As obesity is more prevalent in minorities, higher priorities are placed towa...
A surgical procedure which diverts pancreatobiliary secretions via the duodenum and the jejunum into the colon, the remaining small intestine being anastomosed to the stomach after antrectomy. The procedure produces less diarrhea than does jejunoileal bypass.
Surgical procedures aimed at producing major WEIGHT REDUCTION in patients with MORBID OBESITY.
Activities related to WEIGHT REDUCTION in patients with OBESITY. Treatment methods include DIET; EXERCISE; BEHAVIOR MODIFICATION; medications; and BARIATRIC SURGERY.
The discipline concerned with WEIGHT REDUCTION in patients with OBESITY.
Surgical procedures conducted with the aid of computers. This is most frequently used in orthopedic and laparoscopic surgery for implant placement and instrument guidance. Image-guided surgery interactively combines prior CT scans or MRI images with real-time video.
