BACKGROUND: To report the surgical techniques and results of robot-assisted radical cystectomy (RARC) with intracorporeal Mainz Ⅱ rectosigmoid pouch at our centre.
METHODS: Two female patients were treated with this procedure. Construction of the pouch was divided into four main steps: incision of the rectum and sigmoid colon, closure of the posterior wall of the pouch, reimplantation of the ureters at the bottom of pouch in an anti-reflux manner, and closure of the anterior wall. Surgical results and perioperative complications were assessed.
RESULTS: The operations were performed completely intracorporeally. No perioperative complications were observed. Postoperatively, high-grade invasive urothelial carcinoma was detected. On postoperative day 60, no bilateral ureteral dilation was detected. Two patients demonstrated total continence. Clinical recurrence was not observed during the follow-up period.
CONCLUSIONS: With careful patient selection, robot-assisted intracorporeal Mainz Ⅱ rectosigmoid pouch might be a simple minimally invasive surgical technique to be evaluated in repeated applications.
