Cyanoacrylate sealant compared to fibrin glue in staple line reinforcement during laparoscopic sleeve gastrectomy. Pilot prospective observational study.

Laparoscopic Sleeve Gastrectomy (LSG) is associated with serious complications, such as staple line leaks and bleeding. This paper presents a novel approach aimed at the successful consolidation of the suture by the use of the cyanoacrylate, here compared to the use of fibrin glue. Fifty consecutive patients, recruited from October 2015 to March 2016, were submitted to laparoscopic sleeve gastrectomy by standardized surgical technique. The staple line was reinforced with cyanoacrylate or fibrin glue. There were no post-operative complications and no operative time prolongation. An early removal of the draining and a reduction of the average hospitalization were observed. The results suggest that staple line reinforcement with cyanoacrylate during laparoscopic sleeve gastrectomy is as easy, safe and cost-saving as with fibrin glue. Furthermore, cyanocrilate allows a chemical omentoplasty with the result of restoring the anatomy. Therefore, this approach is viable and useful for future trials on the efficacy in preventing surgical post-operative complications.
