RESUMEN
PURPOSE: To compare laparoscopic gynecological surgery training between a developed country's reference center (host center) and a public reference service in a developing country (home center), and use the technicity index (TI) to compare outcomes and to determine the impact of laparoscopic gynecological surgery fellowship training on the home center's TI. METHODS: The impact of training on the home center was assessed by comparing surgical performance before and after training. TI was assessed in 2017 in the host center, and before and after training in the home center. Epidemiological and clinical data, and information on reason for surgery, preoperative images, estimated intraoperative bleeding, operative time, surgical specimen weight, hospital stay length, complication and reintervention rates were collected from both institutions. Home center pre-training data were retrospectively collected between 2010 and 2013, while post-training data were prospectively collected between 2015 and 2017. A two-tail Z-score was used for TI comparison. RESULTS: The analysis included 366 hysterectomies performed at the host center in 2017, and 663 hysterectomies performed at the home center between 2015 and 2017. TI in the host center was 82.5%, while in the home center it was 6% before training and 22% after training. There were no statistical differences in length of hospital stay, preoperative uterine volume, surgical specimen weight and complication rate between centers. However, significantly shorter mean operative time and lower blood loss during surgery were observed in the host center. CONCLUSIONS: High-quality laparoscopic training in a world-renowned specialized center allowed standardizing laparoscopic hysterectomy procedures and helped to significantly improve TI in the recipient's center with comparable surgical outcomes.

STUDY OBJECTIVE: To demonstrate the application of the so-called reverse technique to approach deep infiltrating endometriosis nodules affecting the retrocervical area, the posterior vaginal fornix, and the anterior rectal wall. In Video 1, the authors describe the complete procedure in 10 steps in order to standardize it and facilitate the comprehension and the reproduction of such a procedure in a simple and safe way. DESIGN: A case report. SETTING: A private hospital in Curitiba, Paraná, Brazil. PATIENT: A 32-year-old woman was referred to our service complaining about cyclic dysmenorrhea, dyspareunia, chronic pelvic pain, and cyclic dyschezia. Transvaginal ultrasound with bowel preparation showed a 2.4-cm endometriotic nodule at the retrocervical area, uterosacral ligaments, posterior vaginal fornix, and anterior rectal wall, infiltrating up to the muscularis 10 cm far from the anal verge. INTERVENTIONS: Not applicable. MEASUREMENTS AND MAIN RESULTS: Under general anesthesia, the patient was placed in the dorsal decubitus position with her arms alongside her body and her lower limbs in abduction. Pneumoperitoneum was achieved using a Veress needle placed at the umbilicus. Four trocars were placed according to the French technique as follows: a 10-mm trocar at the umbilicus for the 0 degree laparoscope; a 5-mm trocar at the right anterosuperior iliac spine; a 5-mm trocar in the midline between the umbilicus and the pubic symphysis, approximately 8 to 10 cm inferior to the umbilical trocar; and a 5-mm trocar at the left anterosuperior iliac spine. The entire pelvis was inspected for endometriotic lesions (step 1). The implants located at the ovarian fossae were completely removed (step 2). The ureters were identified bilaterally, and both pararectal fossae were dissected, preserving the hypogastric nerves (step 3). The lesion was separated from the retrocervical area, and the posterior vaginal fornix was resected (reverse technique), leaving the disease attached to the anterior surface of the rectum (step 4). The lesion was shaved off the anterior rectal wall using a harmonic scalpel (step 5). The anterior rectal wall was closed using X-shaped stitches of 3-0 polydioxanone suture in 2 layers (step 6). The specimen was extracted through the vagina (step 7). The posterior vaginal fornix was reattached to the retrocervical area using X-shaped sutures of 0 poliglecaprone 25 (step 8). A pneumatic test was performed to check the integrity of the suture (step 9). At the end of the procedure, hemostasis was controlled, and the abdominal cavity was irrigated using Lactate ringer solution (step10). CONCLUSION: The laparoscopic reverse technique is an alternative approach to face retrocervical or rectovaginal nodules infiltrating the anterior rectal wall. In this technique, the separation of the nodule from the rectal wall is performed at the end of the surgery and not at the beginning as performed within the traditional technique. This enables the surgeon to perform a more precise dissection of the endometriotic nodule from the rectal wall because of the increased mobility of the bowel. The wider range of movements serves as an ergonomic advantage for the subsequent dissection of the lesion from the rectum, allowing the surgeon to decide the best technique to apply for the treatment of the bowel disease (rectal shaving or discoid or segmental resection).
