Study ObjectiveTo compare learning curves for laparoendoscopic single-site surgery (LESS) for ovarian tumors according to the type of procedure (oophorectomy vs cystectomy).DesignA prospective cohort study. (Canadian Task Force Classification II-2).SettingUniversity hospital.PatientsOne hundred fifteen patients who planned to undergo LESS for ovarian tumors by a surgeon between May 2008 and August 2010.InterventionsLESS.Measurements and Main ResultsThe learning curve was assessed through the graph between the operative time and sequence of cases. Proficiency, defined as the point at which the slope of the learning curve became less steep, and surgical outcome were compared between the two surgery groups. LESS was successfully completed in 103 of 115 patients (94.8%). Learning curve for oophorectomies (n = 59) showed a continued slow slope with no apparent proficiency, suggesting oophorectomies did not pose an initial technical challenge. However, proficiency in cystectomies (n = 56) was evident at the thirty-third case. Furthermore, the oophorectomy group had a shorter operative time and less need for additional ports than the cystectomy group (69.4 minutes vs 100.1 minutes; 5.1% vs 14.3%).ConclusionOophorectomy rather than cystectomy is recommended as the initial procedure to start with LESS for ovarian tumors.
