Can 3D Laparoscopy Improve Surgical Performances in Surgeons in Training?

All patients with benign uterine pathology at preoperative examinations (pelvic ultrasound and/or magnetic resonance and/or CT scan) and with indication for total laparoscopic hysterectomy, will be enrolled in the study. While under general anesthesia, the patient is positioned in the dorsal lithotomic position with both legs supported in stirrups with a Trendelenburg tilt and arms along the body. A four disposable or reusable, sterile trocar transperitoneal approach is used. A 10 mm port is inserted at the umbilicus for the telescope. Once pneumoperitoneum (12 mmHg) is achieved, intra-abdominal visualization will be obtained with a 0° high-definition telescope (HD EndoEye 10 mm, Olympus Winter \& IBE GMBH, Hamburg - Germany) or with 0° 3D laparoscopy high-definition (Olympus Winter \& IBE GMBH, Hamburg - Germany). The instruments used include bipolar grasper, monopolar scissors, monopolar hook, various graspers and a suction irrigation system. Clermont Ferrand uterine manipulator (Model K.Storz Endoskope,Tuttlingen, Germany) is optionally used to move the uterus. Total hysterectomy is then performed according to standard technique used by the recruiting center (development of the pararectal space and identification of uterine artery, coagulation of ovarian pedicles, development of the vesico-uterine septum, colpotomy).The vaginal vault is then closed with a 0 Vycril suture laparoscopically (continuous suture). Detailed operative time, intra and post operative early complications will be recorded (Extended Clavien-Dindo classification of surgical complications will be used for post operative complications)
