Factors Related to Bleeding and Leak Rates After Robotic Sleeve Gastrectomy

Background Robotic sleeve gastrectomy has been increasing in annual incidence in recent years. Although rare, post op bleeding and leak in these cases can lead to significant morbidity, mortality, and healthcare utilization.Objectives To determine preop comorbidity risk factors and operative techniques associated with risk of bleeding or leak within 30 days of robotic sleeve gastrectomy.Methods The MBSAQIP database was analyzed. A total of 53,548 RSG cases were included in analysis. Surgeries took place from accredited centers in the USA from 2015 to 2019.Conclusions Preoperative anticoagulation, renal failure, COPD, and OSA were found to increase in the risk for transfusion requirements after SG. Receiving a transfusion and smoking increased the risk for leak. Staple line reinforcement significantly decreased transfusion and leak rates. Staple line oversewing did not have an impact on bleeding or leak.
