Abstract BACKGROUND: Conflicting data have been published regarding whether Helicobacter pylori (HP) positivity is associated with increased complication rates in patients undergoing Roux-en-Y gastric bypass (RYGB). METHODS: We retrospectively examined the rate of complications in patients undergoing RYGB according to preoperative HP positivity and persistent post-treatment positivity to determine whether a correlation exists. RESULTS: A total of 228 patients underwent RYGB during a 2-year period (2009-2011). No patient had evidence of active ulcer disease on preoperative endoscopy. Of the 228 patients, 68 tested positive for HP on serum antigen screening and were treated with omeprazole, clarithromycin, and amoxillin. After treatment, 24 patients were persistently positive on repeat endoscopic biopsy. Of the 228 patients, 12 experienced a total of 13 complications (stomal stenosis in 8, marginal ulcer in 5, and none with anastomotic leak or gastrointestinal bleeding). Of the 68 patients with HP positivity preoperatively, 1 complication (2.3\%) developed in the 44 patients who had responded to triple therapy, and no complications occurred in the 24 patients who had remained positive after treatment (P = 1.00), showing no difference. Also, no significant difference was found in the rate of complications (P = .11) between patients who were HP negative preoperatively (11 of 160, 6.9\%) and those who were positive preoperatively (1 of 68, 1.5\%). CONCLUSION: HP status, whether positive preoperatively or persistently positive after treatment, had no effect on the marginal ulcer or stomal stenosis rates in patients undergoing RYGB in the present study.
