Abstract
INTRODUCTION
The main drawback of laparoscopic sleeve gastrectomy (LSG) is the severity of postoperative complications. Staple line reinforcement (SLR) is strongly advocated. Recently, over-sewing has been proposed as a cost-effective and helpful method for reinforcing the staple line. The purpose of this study was to report our initial experience with LSG comparing over-sewing over the entire staple line with the upper-third staple line.

MATERIALS AND METHODS
All obese patients seen at Negrar Sacro Cuore, Don Calabria Hospital were entered into our prospective database and were retrospectively evaluated. Complications (divided as major complications: leaks and bleeding; and minor complications: dysphagia, esophagitis, and reflux disease) and reoperations were recorded for all patients. Complications were graded according to the Clavien classification system.

RESULTS
From February 2015 to March 2016, 30 patients underwent LSG. Patients were divided in two groups according to over-sewing: Group A-over-sewing over the entire staple line; and Group B upper-third over-sewing. Mean total operative time was longer in Group A-90 minutes-compared with 85 minutes in Group B. In regard to minor complications, we reported one esophagitis and two cases of dysphagia in Group B and one dysphagia in Group A. Gastroesophageal reflux was higher in Group B than in Group A (3 vs. 1, p=0.149). Three major complications were observed (10%): two bleeding and one hematoma in Group B and no major complications occurred in Group A. All major complications were conservatively treated. No leaks were reported in both groups. No mortality was observed.

CONCLUSIONS
Over-sewing of the staple line was associated with fewer leaks but no conclusions can be drawn regarding the effects of over-sewing on staple line bleedings. Before standardizing surgical techniques further, trials are necessary to improve our knowledge about over-sewing in LSG.
