Spinal Anesthesia Versus General Anesthesia for Single Port Access Laparoscopic Adnexal Surgery: A Propensity Score-Matching Analysis

Abstract

Study Objective The purpose of this study was to compare the surgical outcomes of single-port-access(SPA) laparoscopic adnexectomy under spinal anesthesia and general anesthesia and to evaluate the feasibility of laparoscopic adnexectomy under spinal anesthesia. Design Canadian Task Force Classification II-1, This study was conducted at Wonju Severance Christian Hospital from March 2017 to September 2019. Setting N/A Patients or Participants Total 111 patients were enrolled prospectively. Interventions All patients underwent SPA laparoscopic adnexal surgery(Bilateral or unilateral salpingo-oophorectomy); 89 patients under general anesthesia and 22 patients under spinal anesthesia. To reduce the effect of selection bias and potential confounding in this study, estimated propensity scores were used to match the spinal anesthesia group to the general anesthesia group. Measurements and Main Results Patient characteristics showed no statistical difference between 2 groups. The postoperative pain 6 hours after operation was significantly higher in spinal anesthesia group (2.78 ± 0.78 vs. 3.80 ± 1.99; p = 0.035). The postoperative pain after 2, 12, 24, 49 hours showed no significant difference between 2 groups. The use of patient controlled analgesia(78.6% vs. 23.8%; p Conclusion Performing SPA laparoscopic adenxal surgery under spinal anesthesia is feasible. And spinal anesthesia can be another option while performing laparoscopic surgery in gynecologic field.
