Obesity surgery

Anastomotic stricture after gastric bypass for morbid obesity has been reported as the most frequent complication after surgery. The objective of this study is to determine in a prospective and consecutive endoscopic evaluation the true incidence of this complication early and late after gastric bypass. ⋯ Stricture at the gastrojejunal anastomosis after gastric bypass is the commonest complication early after surgery. Near 60% present a mild stricture (with a diameter between 7 and 9 mm), being 28% asymptomatic. This complication is easily treated by endoscopic procedure if it is diagnosed early (3 to 4 weeks) after surgery. Routine endoscopy 1 month after surgery is the only objective scientific way to determine the real true incidence of this complication.
