HALON-hysterectomy by transabdominal laparoscopy or natural orifice transluminal endoscopic surgery: a randomised controlled trial (study protocol).

Introduction: Natural orifice transluminal endoscopic surgery (NOTES) uses natural body orifices to access the cavities of the human body to perform surgery. NOTES limits the magnitude of surgical trauma and has the potential to reduce postoperative pain. This is the first randomised study in women bound to undergo hysterectomy for benign gynaecological disease comparing NOTES with classical laparoscopy.
