The use of different bougie diameters had no impact on the volume of resected stomach, morbidity or short-term weight loss after LSG, although a trend was seen toward better weight loss with the smaller bougie. A longer-lasting follow-up will be necessary to further assess differences.

Our evidence suggests that hospital stays after LSG beyond 24 h are unnecessary in patients with no persistent vomiting or signs of bleeding or leaks; major complications generally present either within the first 24 h or after the fifth postoperative day.
