One in three women of reproductive age utilize tubal sterilization for contraception, and sterilization is often requested at time of cesarean delivery. Complete salpingectomy for the purpose of permanent sterilization at the time of cesarean birth is increasingly being performed worldwide. A preferred complete salpingectomy technique for the purpose of sterilization at the time of cesarean delivery has not emerged in current practice. The objective is to compare short-term clinical outcomes and cost of salpingectomy using a hand-held bipolar energy instrument with those of traditional suture ligation. This retrospective cohort study will be conducted from 2017-2023 at a single tertiary care hospital. The investigators hypothesize that bipolar energy instrument use will not significantly improve clinical outcomes.
