Background
Different anastomotic techniques have been evaluated during a laparoscopic Roux-en-Y gastric bypass (RYGB); however, no techniques have proven to be better than any other regarding complications and the percentage of weight loss (excess weight loss (%EWL)), and there are few controlled prospective studies to compare them.
Methods
A randomized, prospective study was conducted in 238 patients undergoing RYGB for morbid obesity between July 2008 and September 2012 to compare the early and late postoperative complications between the two surgical techniques: gastrojejunal hand-sutured anastomosis (HSA) and circular-stapled anastomosis (CSA). Minimum follow-up was 24 months.
Results
The two groups of patients were similar for demographic data and preoperative comorbidities. There were no significant differences between the surgical techniques regarding %EWL at 3, 12, and 24 months. The patients with CSA had a greater frequency of postoperative gastrointestinal bleeding (GIB) (4.2 vs. 0 %, p = 0.024) and surgical wound infection (11.1 vs. 3.4 %, p = 0.025) than the patients with HSA, with no significant differences in the other early complications. There were no significant differences in either group for late complications (gastrojejunal anastomosis (GJA) stricture, marginal ulcer, GJA perforation, bowel obstruction, and eventration). No significant differences were observed in operative time, rate of reoperation and postoperative length of hospital stay.
Conclusions
HSA and CSA were techniques with similar safety and effectiveness in our study. HSA had a lower rate of bleeding complications and surgical wound infection, although it does require greater experience in laparoscopic hand suturing.
