Totally intracorporeal colorectal anastomosis (TICA) after segmental colorectal resection for deep endometriosis: technical notes and case series

Purpose: The aim of this study was to evaluate the safety and feasibility of totally intracorporeal colorectal anastomosis (TICA) in patients undergoing colorectal resection for the treatment of deep endometriosis (DE) affecting the bowel. Methods: Between January 2021 and August 2024, 33 consecutive patients with DE treated with segmental colorectal resection were enrolled. In 30 patients, TICA was performed. Demographic, operative, and postoperative data were collected retrospectively. Results: The mean distance between the endometriotic nodule and the anal verge was 11.5 (7-18) cm. The mean operative time was 282.83 (190-512) minutes. No major intraoperative complications occurred. Three (10%) patients developed a minor (Clavien‒Dindo grade I/II) postoperative complication. Conclusion: TICA is a safe and feasible technique and represents a valid alternative reconstruction method after colorectal resection for DE.
