title: Gastrojejunal anastomotic stenosis after laparoscopic gastric bypass. Experience in 280 cases in 8 years.
abstract: OBJECTIVE
  Gastrojejunal stricture (GYS), not only is a common complication after laparoscopic gastric bypass, but its frequency is about 15% according to bibliography. Our aim is to present our experience after 280 laparoscopic gastric bypass.
  
  
  METHODS
  From January 2004 to December 2012, 280 patients underwent a laparoscopic Roux en Y gastric bypass with creation of the gastrojejunal anastomosis is performed with circular stapler type CEAA No 21 in 265 patients and with a linear stapler in 15 patients. In all patients with persistent feeding intolerance were performed barium transit and/or gastroscopy. When gastrojejunal stricture showed proceeded to endoscopic pneumatic dilation.
  
  
  RESULTS
  Twenty cases (7.1%) developed a gastrojejunal stricture, in 4 of these cases the initial diagnosis was made by barium transit and all case were confirmed by endoscopy. Five patients had a history of digestive bleeding that required endoscopic sclerosis of the bleeding lesion. All cases were resolved by endoscopic dilatation. One patient suffered a perforation and a re-intervention. At follow-up has not been detected re-stricture.
  
  
  CONCLUSIONS
  Structure at the gastrojejunal anastomosis after gastric bypass is the commonest complication early after surgery. Endoscopic balloon dilatation is a safe and effective therapy.
