Abstract
Purpose
Marginal ulcer (MU) is a known complication after Roux-en-Y gastric bypass (RYGB) that carries significant morbidity. First, we aimed to determine the trends and the rates of readmission, reintervention, and reoperation of 30-day MU. Second, we aim to determine the predictive factors associated with this complication.
Materials and Methods
Patients who had 30-day marginal ulcer (MU) after LRYGB were identified using the 2015–2021 MBSAQIP database. Those who had a 30-day complication other than MU were excluded. Bivariate and logistic regression analyses were performed.
Results
Among 213,104 patients undergoing laparoscopic RYGB, 638 (0.3%) showed 30-day MU. This group of patients required endoscopic interventions, readmissions, and reoperations at rates of 88%, 72%, and 9%, respectively. Predictive factors for 30-day MU after RYGB were renal insufficiency, history of DVT, previous cardiac stent, African American race, chronic steroid use, COPD, therapeutic anticoagulation, anastomotic leak test, GERD, and operative time > 120 min. Additionally, patients who had 30-day MU showed significantly higher rates of overall complications such as pulmonary, cardiac and renal complications, unplanned ICU admission, blood transfusions, venous thromboembolism (VTE), and non-home discharge (p < 0.05). The MU group showed similar rates of 30-day mortality as those without this complication (0.2% vs 0.1%, p = 0.587).
Conclusions
The incidence of 30-day MU following RYGB was 0.3%. Patients with MU required endoscopic interventions, readmissions, and reoperations at rates of 88%, 72%, and 9%, respectively. Some preoperative and intraoperative factors contributed to an increased risk of 30-day MU.

Key Points
• The incidence of 30-day marginal ulcer (MU) after Roux-en-Y gastric bypass was 0.3%. The rates of 30-day MU have decreased from 3.48 to 2.37 per 1000 person/year from 2015 to 2021.
• Patients with 30-day MU required endoscopic interventions, readmissions, and reoperations at rates of 88%, 72%, and 9%, respectively.
• Preoperative factors such as renal insufficiency, history of DVT, previous cardiac stent, African American race, chronic steroid, COPD, anticoagulation use, and GERD, and intraoperative factors such as anastomotic leak test and increased operative time were identified as predictive factors for 30-day MU.
