OBJECTIVE: To investigate the learning curve of transvaginal natural orifice transluminal endoscopic hysterectomy (tVNOTEH) when using a standard operating procedure (SOP). METHODS: Seventy-nine patients were treated with tVNOTEH by a single surgeon. The SOP for tVNOTEH was created after the first eight cases. Patients' perioperative data were retrospectively reviewed. Operative time (OT) was regarded as a replaceable marker for surgical competency. The learning curve was drawn using the cumulative sum method. RESULTS: All patients completed surgeries without switching to other surgical paths. The overall mean OT was 90.23 ± 29.85 min. Four unique phases of the learning curve were identified: phase I (the exploring stage over eight cases), phase II (after adopting the SOP, acquirement of competence over 20 cases), phase III (post-learning of 19 cases, in which more difficult cases were introduced), phase IV (more adept at tVNOTEH), with OT 113.75 ± 43.07 min, 82.50 ± 25.88 min, 101.05 ± 27.83 min, 82.75 ± 25.53 min, respectively. No significant differences were found apart from OT, uterine size, and disease types. CONCLUSION: Our data demonstrated four distinct phases of the learning curve of tVNOTEH. For an experienced surgeon, surgical competence in tVNOTEH can be grasped after eight cases. With SOP, surgical competence could be rapidly acquired.
