Evolution of surgical steps in robotics-assisted donor surgery for uterus transplantation: results of the eight cases in the Swedish trial

摘要

OBJECTIVE: To perform a stepwise development of the surgical method for robotics-assisted laparoscopy in donor hysterectomy for uterus transplantation (UTx), a unique treatment for absolute uterine-factor infertility. DESIGN: Prospective observational study. SETTING: University hospital. PATIENT(S): Eight donors, aged 38-62 years, underwent surgery for retrieval of the uterus and vasculature. INTERVENTION(S): Robotics-assisted laparoscopy was performed in donors for 6-7 h with video recording. Conversion to laparotomy was performed for last parts of retrieval surgery. MAIN OUTCOME MEASURE(S): Description, evaluation, and timing of 12 specific surgical steps, as well as surgical outcomes and complications. RESULT(S): There was a progression during the course of eight surgeries. In the initial two cases, seven and six items were completed with robotics compared with all 12 items in the last three procedures. The passive surgical time decreased from ∼20% in the first four cases to ∼8% in the last three procedures. The estimated median (range) blood loss, total surgical time, and length of hospital stay were, respectively, 125 mL (100-600), 11.25 h (10-13), and 5.5 days (5-6). Two reversible complications occurred: One patient acquired pressure alopecia, and one developed pyelonephritis. CONCLUSION(S): The study demonstrates a clear evolution of a strategy toward fully robotic donor surgery in UTx. This is likely to become the main approach in donor surgery of live UTx donors.
