Introduction: No single gastrojejunostomy anastomosis technique (GJA) in Laparoscopic Roux-en-Y gastric bypass (LRYGB) is currently preferred over another. Bendewald et al. confirmed that there was no difference in anastomotic stricture rates when comparing hand-sewn (HS), linear-stapled (LS), and circular-stapled (CS) GJA techniques. We present and analyze our own institutional data to readdress stricture rates.
Methods: From January 2010 to January 2013, 860 consecutive patients underwent LRYGB using HS, LS, and CS anastomotic techniques at a single institution. All patients in this study were followed to see if they had a complication of a stricture within this time period. Hospital records were retrospectively reviewed and those who had stricture complications shown on endoscopy requiring intervention were compiled and compared using univariate analysis.
Results: Patient demographics did not differ substantially between the three groups. The most common technique employed was LS (n = 429, 49.8%), followed by CS (n = 254, 29.5%) and HS (n = 177, 20.6%), respectively. Using multivariate analysis, there was a significant difference in the rate of strictures between the anastomotic techniques (LS 4.42%, HS 2.82%, CS 1.18%, p = 0.0163).
Conclusions: Our data show that the discussion of which anastomotic technique is superior should be reopened given the statistically significant low rate of strictures in patients who underwent LRYGB with a CS anastomosis in comparison with LS and HS anastomoses.
