Endoscopic findings and their clinical correlations in patients with symptoms after gastric bypass surgery - 31/08/11
Abstract |
Background |
The aim of this study was to describe the endoscopic findings in patients with upper GI symptoms after Roux-en-Y gastric bypass surgery and to correlate clinical features with endoscopic findings.
Methods |
Patients with symptoms after Roux-en-Y gastric bypass referred for endoscopy were studied. Endoscopy was performed in standard fashion with a 9.8-mm diameter endoscope.
Results |
Forty-nine patients underwent a total of 69 upper endoscopy procedures between January 2001 and February 2003. The most common endoscopic findings were the following: normal post-surgical anatomy (21 patients, 43%), marginal ulcer (13 patients, 27%), stomal stenosis (9 patients [19%], including 5 with a concomitant marginal ulcer), and staple-line dehiscence (8 patients [16%], including one with a marginal ulcer). Abdominal pain was the most common symptom (26 patients, 53%) and was more frequent among patients with a normal endoscopy compared with those with an abnormal endoscopy (p=0.04). Stomal stenosis was present in 39% of patients with nausea, vomiting, or dysphagia; it was not present in any patient without these symptoms (p=0.001). Fifteen percent of procedures performed within the first 6 postoperative months were normal, compared with 53% of those performed beyond 6 months (p=0.02). There was no complication of endoscopy.
Conclusions |
Among patients with symptoms after Roux-en-Y gastric bypass presenting for endoscopy, normal post-surgical anatomy was the most common finding. Marginal ulcer was the most common abnormality. Presentation with abdominal pain and performance of endoscopy beyond the 6th post-operative month were predictive of a normal endoscopy, and lack of nausea, vomiting, and dysphagia predicted the absence of stomal stenosis.
