Revision Gastrojejunostomy Versus Suturing With and Without Omental Patch for Perforated Marginal Ulcer Treatment After Roux-en-Y Gastric Bypass.

Background: Ulceration at the gastrojejunostomy is a late bariatric surgery complication in 0.6-16% of Roux-en-Y gastric bypass (RYGB) patients. As there is no general consensus on management of acute ulcer perforations, we compare two methods of surgical repair: the most commonly performed procedure, suturing of ulcer with or without omental patch versus revision gastrojejunostomy (RG).

Methods: A retrospective chart review of cases at a single large, Midwestern US high-volume bariatric center from November 2, 2006 through March 11, 2021 identified 144 RYGB patients undergoing surgical repair for a perforated ulcer: 72 treated by SGP and 72 by RG. Outcomes, including length of stay, leaks, readmissions, and reoperations, were compared. Categorical variables were compared by Chi-square tests and continuous variables by ANOVA.

Results: Patients were primarily female (77.1%) and Caucasian (97.2%), 49.7 ± 12.5 years old, and 90.6 ± 26.6 kg. Most had laparoscopic RYGBs (98.6%). There were no demographic differences between groups. Of the RG patients, 11.4% experienced ulcer recurrence versus 41.7% of SGP patients (p < .001), and 2.8% of RG versus 11.1% of SGP patients required a reversal (p < .05). No significant differences between groups occurred in time to perforation (3.2 vs. 2.5 years for RG and SGP groups, respectively), length of stay (5.0 vs. 6.8 days), leaks (1.4% vs. 2.8%), readmissions (4.2% vs. 4.2%), or reoperations (2.8% vs 5.6%).

Conclusions: Patients developing perforated marginal ulcers after RYGB can be safely and effectively treated by revision gastrojejunostomy with a lower likelihood of ulcer recurrence. Short-term morbidity was comparable to suturing with or without an omental patch.
