Background
Laparoscopic roux-en-Y gastric bypass (LRYGB) is the gold standard weight-loss procedure. There are different techniques to perform the gastrojejunal (GJ) anastomosis, but there is no consensus as to which one is superior for weight loss. Our goal in this study was to assess one-year weight loss after LRYGB comparing the three different techniques at our tertiary care center.
Methods
The American college of surgeons (ACS) Metabolic and Bariatric Surgery Accreditation and Quality Improvement Program (MBSAQIP®) data for Montefiore Medical Center for years 2014–2017 were analyzed. Three surgeons were included in this study; each type of anastomosis was performed by a single surgeon. Patients were included if they underwent primary LRYGB. Patients were designated to one of three different groups depending of the type of gastrojejunal anastomosis performed: hand sewn, circular stapled, or linear stapled. One-year weight loss was assessed as primary endpoint of the study. A descriptive analysis of perioperative variables for each group was included as well.
Results
A total of 1011 patients underwent primary LRYGB. 429 (42.1%) were performed with circular-stapled GJ anastomosis, 433 (42.5%) with a hand-sewn GJ anastomosis, and 149 (14.6%) linear-stapled GJ anastomosis. The median BMI was 46.08 ± 6.43, with no difference between groups (p = .405). Procedure time was 106.70 ± 28.23 min for the circular group, 108.27 ± 28.59 min for the hand-sewn group, and 115.78 ± 36.11 min for the linear group (p > 0.005). There were no significant differences in complications except for the need of postoperative transfusions (p < 0.002). There was no statistically significant difference in %EWL one year after surgery: %EWL was 58.81 ± 16.54 kg for hand sewn, 58.86 ± 14.84 kg for circular, and 59.20 ± 17.58Kg for linear. (p = .595).
Conclusion
There is no difference in weight loss one year after LRYGB based on the type of gastrojejunal anastomosis performed.
