Background
Marginal ulceration (MU) and bleeding are possible complications following laparoscopic Roux-en-Y gastric bypass (RYGB). Our institution utilizes three techniques for performing the gastrojejunal anastomosis (GJA), providing a means to compare postoperative MU and bleeding as it relates to GJA technique.
Objectives
We sought to analyze the incidence of MU and bleeding between the 25-mm end-to-end anastomosis (EEA) stapler, linear stapler (LS), and robotic hand-sewn (RHS) GJA techniques.
Methods
Electronic health records for all patients who had an upper endoscopy (EGD) after RYGB were queried (2010–2014). Charts were retrospectively reviewed for type of GJA, complications, endoscopic interventions, and smoking and NSAID use.
Results
Out of 1112 RYGBs, the GJA was created using an EEA, LS, or RHS approach in 58.6%, 33.6%, and 7.7% of patients, respectively. 17.4% had an EGD (19.9% EEA, 13.9% LS, and 14.0% RHS). Incidence of MU was 7.3% (9.3% EEA, 4.8% LS, and 5.8% RHS). Rates of EGD and MU were significantly higher after EEA vs. LS GJA (p<0.05). The bleeding rate was 1.5%, [1.1% EEA, 2.1% LS, and 2.3% RHS (p=NS)]. MU within 90 days of RYGB occurred in 4.1%, 0.8%, and 4.7%, respectively (p<0.05 for EEA vs LS only). NSAID and cigarette use were identified in 29.3%, 38.9%, and 60% and 17.2%, 22.2%, and 20%, respectively, for the EEA, LS, and RHS GJA (p=NS).
Conclusion
The method of GJA has an impact on rate of MU formation. A GJA fashioned with a 25-mm EEA stapler tends to have higher rates of EGD and MU.
