Use of fibrin glue in bariatric surgery: analysis of complications after laparoscopic sleeve gastrectomy on 450 consecutive patients

Laparoscopic Sleeve Gastrectomy (LSG) is one of the most performed surgical procedures in bariatric surgery. Staple line leak and bleeding are by far the two most feared complications after LSG. In this study, we retrospectively compared the efficacy of Fibrin Glue in preventing staple line leak and bleeding. From September 2019 to January 2020, 450 obese patients underwent elective LSG and were placed into groups with Fibrin Glue reinforcement (Group A) or without Fibrin Glue reinforcement (Group B). Primary endpoints were postoperative staple line leak and bleeding; while, secondary endpoints were reintervention rate, total operative time and mortality. Mean Body Mass Index (BMI) was 45.4 ± 7.9 kg/m² (range: 35.1–81.8). Mean age was 43.3 ± 11.8 years (range: 18–65). No intraoperative complications or conversion to laparotomy were reported. Mean operative time was comparable between the groups (48 ± 18 min in Group A vs 48 ± 14 min in Group B; p > 0.05). No decrease in overall postoperative complications was found in Group A (5.1% vs 7.0%; p > 0.05), but after stratification according to Clavien–Dindo classification, we found a higher rate of Grade II (0.0% vs 1.6%; p < 0.05) and Grade IIIb (0.0% vs 1%; p < 0.05) complications in group B. Our study showed that Fibrin Glue as a reinforcement method during LSG is a reliable tool, without affecting the operative time of surgery and mortality. A significant reduction in complications (Clavien–Dindo grade II and grade IIIb) was observed in patients undergoing LSG with Fibrin Glue.
