OBJECTIVE To assess the feasibility of deep endometriosis surgery using robotic assistance, benefits and limits of this approach. METHOD Case-series study enrolling patients managed for deep infiltrating endometriosis (DIE) using robotic assistance in our department between September 2011 and March 2014 (NCT02294825). Self-questionnaires including pain and digestive symptoms were filled in preoperatively and 1 year after surgery. RESULTS Thirty-five patients were enrolled in the series. They represented 54% of patients managed for gynecological disease by laparoscopic route with robotic assistance during the study period, and 14% of patients managed for deep endometriosis in our department. Follow-up averaged 24±8 months, and no patient was lost to follow-up. Thirty-two patients had rectal involvement: rectal shaving was performed in 25 patients, disc excision in 3 and colorectal resection in 4. Three patients had bladder resection. Thirteen patients presented with deep endometriosis of the ureters: ureterolysis was performed in 11 of them, and resection of the ureter followed by reimplantation into the bladder in 2 patients. One major complication (Clavien IIIb) was recorded in a patient presenting with necrosis of the right ureter on postoperative day 5. Nine patients tried to conceive after surgery and 8 have already become pregnant (88.9%). One year after surgery, self-questionnaires revealed a significant decrease in pain symptoms and significant improvement in several item values of gastrointestinal standardized questionnaires. CONCLUSIONS Surgical management of DIE is feasible using robotic assistance. However, data available in the literature and our own experience do not definitively support the hypothesis of the superiority of robotic assistance in the management of DIE.
