Introduction Laparoscopic sleeve gastrectomy (LSG) is one of the most frequently performed bariatric procedures performed worldwide. However, staple line-related complications have become a major challenge for bariatric surgeons. The aim of this study was to evaluate the morbidity in a cohort of patients who underwent LSG with imbricated oversewing of the staple line at a single high-volume center. Materials and Methods We retrospectively reviewed prospectively collected data for all patients who underwent LSG to treat obesity at our institution from January 2010 to September 2016. All practitioners had undergone training with a single senior bariatric surgeon using oversewing as staple line reinforcement (SLR). Results In total, 1023 LSGs were performed (female, 67.3%; mean age, 40.6 ± 10.8 years; median preoperative body mass index, 37 ± 4.5 kg/m 2 ). The mean operative time was 67.6 ± 23.4 min (range, 30–150 min). The rate of conversion to open surgery was 0.3%. Early complications were noted in 18 patients (1.8%), including 5 cases of bleeding (0.5%). No leaks, stenosis, or mortality occurred. Conclusions LSG is a safe technique, but staple line-associated complications can be life-threatening. In this series, no leaks occurred from the very beginning of the surgeons’ experience in LSG. Imbricated oversewing of the staple line, proper mentoring, and performance of surgery in appropriate settings are good approaches to decreasing complications.
