Gastrojejunal Anastomotic Stenosis After Laparoscopic Gastric Bypass. Experience in 300 Cases in 8 Years

Abstract

ObjectiveGastrojejunal stricture (GYS), is not only a common complication after laparoscopic gastric bypass, but its frequency is also about 15% according to bibliography. Our aim is to present our experience after 280 laparoscopic gastric bypass. Patients and methodFrom January 2004 to December 2012, 280 patients underwent a laparoscopic Roux en Y gastric bypass with creation of the gastrojejunal anastomosis, which was 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 barium transit and/or gastroscopy were performed. When gastrojejunal stricture showed proceeded to endoscopic pneumatic dilation. ResultsTwenty cases (7.1%) developed a gastrojejunal stricture; in 4 of these cases the initial diagnosis was made by barium transit and all cases 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 re-stricture has not been detected. ConclusionStricture at the gastrojejunal anastomosis after gastric bypass is the commonest complication early after surgery. Endoscopic balloon dilatation is a safe and effective therapy.
