Summary
Brief summary (as posted)
This prospective observational study aims to evaluate the learning curve of obstetrics and gynecology residents performing Vaginal Natural Orifice Transluminal Endoscopic Surgery (V-NOTES) hysterectomy in a university hospital setting. V-NOTES hysterectomy is a minimally invasive surgical technique performed through the vaginal route that combines the advantages of laparoscopy without requiring abdominal incisions. The study will assess the progression of surgical performance of a resident performing V-NOTES hysterectomy under the supervision of an experienced attending surgeon. Key operative and postoperative outcomes will be recorded to evaluate the acquisition of surgical proficiency over time.
