Robotic-assisted laparoscopic repair of rectovesical fistula after Hartmann's reversal procedure.

The case is of a 59-year-old male with history of severe ischemic colitis following emergent intervention for a ruptured infrarenal aortic aneurysm who subsequently underwent left hemicolectomy, partial proctectomy, and Hartmann colostomy. The patient later underwent reversal of the Hartmann colostomy with diverting ileostomy. The surgery was complicated by a right ureteral and posterior bladder injury that resulted in a large rectovesical fistula involving the right hemitrigone and right ureteral orifice. An attempt to repair the rectovesical fistula at an outside facility was unsuccessful. Then, he underwent a robotic-assisted laparoscopic repair of rectovesical fistula, including simple prostatectomy, excision of rectovesical fistulous tract, rectal closure, peritoneal and omental flap interposition, bladder neck reconstruction, vesicourethral anastomosis and right ureteral reimplantation. There were no intraoperative or postoperative complications, and the patient was discharged at postoperative day 4; cystoscopy at 6-week follow-up demonstrated a successful closure of the fistula, at which time the ureteral stents were removed.
