The Effect of Tissue Adhesive on Surgical Site Infection Following Elective Bariatric Surgery: a Retrospective Cohort Study.

PURPOSE: The reported incidence of surgical site infection (SSI) following bariatric surgery ranges from 1.4 to 30%. The use of skin staples and tissue adhesive was shown to be superior to sutures in reducing SSI in a variety of surgical disciplines; however, this area is under-investigated in elective bariatric surgery. The aim of this study was to examine the effect of tissue adhesive for skin closure on SSI in patients undergoing bariatric surgery.

METHODS: A retrospective analysis was performed to determine the incidence of SSI in patients who underwent elective laparoscopic Roux-en-Y gastric bypass (LRYGB) and laparoscopic sleeve gastrectomy (LSG). Tissue adhesive was selectively used for skin closure during the study period. Patient characteristics, operative data, and 30-day postoperative outcomes were collected from patient charts and the Metabolic and Bariatric Surgery Accreditation and Quality Improvement Program (MBSAQIP) database.

RESULTS: A total of 1,579 patients were included in the study. Tissue adhesive was used in 31.2% of all operations (n = 494). The rate of incisional SSI in our study was 2.2% (n = 35). The use of tissue adhesive was more common in patients who developed incisional SSI compared with those without incisional SSI (54.3 vs. 30.8%, p = 0.003). On multivariate analysis, the use of tissue adhesive remained an independent predictor for the development of incisional SSI (OR 2.77, p = 0.007).

CONCLUSION: The use of tissue adhesive was an independent predictor for incisional SSI following elective bariatric surgery. This is the first study to report the effects of tissue adhesive in this patient population.
