Gastrojejunal anastomosis stricture after laparoscopic gastric bypass. Our experience with 62 patients.
OBJECTIVE
Gastrojejunal stricture (GYS), not only is a common complication after laparoscopic gastric bypass (LGBP), but its frequency is about 15% according to bibliography. Our aim is to present our experience after 62 LGBP.


METHODS
From January 2004 to September-2006, we performed 62 consecutive laparoscopic gastric bypass (Wittgrove's technique). The gastrojejunal anastomosis is performed with auto suture material type CEAA No 21 termino-lateral (ILS, Ethicon). In 4 cases (6.45%) was converted to laparotomy, perform the anastomosis in the same way. Monitoring has a range of 3-35 months, conducted in 61 patients because one patient died of pulmonary thromboembolism in the immediate postoperative period after reoperation, after two weeks of gastric bypass, by necrosis of a small fragment of the remnant gastric. In all patients with persistent feeding intolerance were performed barium transit and/or gastroscopy. When gastrojejunal stricture showed proceeded to endoscopic pneumatic dilation (recommending dilate the anastomosis to a maximum 1.5 cm).


RESULTS
Five cases (8.1%) developed a gastrojejunal stricture, in 4 of these cases the initial diagnosis was made by barium transit and in 1 case by endoscopy. Two patients had a history of digestive bleeding that required endoscopic sclerosis of the bleeding lesion (circumferentially sclerosis within 48 hours of surgery and sclerosis of bleeding points). All cases were resolved by endoscopic dilatation. At follow-up has not been detected re-stricture.


CONCLUSIONS
Clinically, gastrojejunal stricture results in a progressive oral intolerance, revealing stenosis between 1 and 3 months postoperatively. The situations of sclerosis of the bleeding lesions favor, especially in cases of extensive sclerosis. In cases of suspected barium transit offers us a high diagnostic yield. Endoscopic dilatation resolved, so far, all cases.
