BackgroundBleeding and staple-line leak, are the most common complications of laparoscopic sleeve gastrectomy. To decrease the incidence of this complications, a variety of intraoperative reinforcement of staple line is used. Reinforced GIA™ is a new automatic suture device with pre-attached synthetic tissue reinforcement, but no study has evaluated its use in sleeve gastrectomy. The objective of this study is to evaluate the efficacy and safety of this new staple line reinforcement technique in laparoscopic sleeve gastrectomy.MethodsWe conducted a retrospective review of 290 patients who underwent laparoscopic sleeve gastrectomy between January 2013 and January 2016 in which reinforced GIA™ or standard GIA™ was used. Patients preoperative characteristics, Operative time, staple line leaks, staple line bleeds, stenosis, and complications requiring reoperation were collected.ResultsA total of 187 laparoscopic sleeve gastrectomy were performed with standard GIA and 103 with reinforced GIA™. Patient characteristics were not significantly different between the groups. The average operating time in the standard GIA group is 57.41±16.44 min against 50.9±14.12 min in the reinforced GIA group (P=0.006). Two staple line leaks developed in the standard GIA group and reoperated against no patients in the reinforced GIA group, without significant difference between the both groups (P=0.66). Staple line bleeds are less in the reinforced GIA group, only 23 (22.3%) against 78 (41.7%) cases in the standard GIA group (P=0.001). No patients of both groups developed gastric sleeve stenosis.ConclusionsDuring laparoscopic sleeve gastrectomy, the use of a reinforced stapler significantly reduces the operative time and staple line bleeding. No significant difference is evidenced in terms of reduction of staple line leaks with this reinforced stapler.
