PurposeRectal injury is a potential complication of radical prostatectomy. Because laparoscopic radical prostatectomy is still a challenging procedure, we review the incidence and management of rectal injury in 1,000 cases of consecutive laparoscopic radical prostatectomy performed at our institution.Materials And MethodsOf the first 1,000 laparoscopic transperitoneal radical prostatectomies performed between January 1998 and April 2002, 13 (1.3%) were complicated by rectal injury. Mean patient age was 66.5 years (range 58 to 76) and mean prostate specific antigen was 12.9 ng./ml. (range 2.9 to 26). Clinical stage was T1c, T2a and T2b in 5, 7 and 1 patient, respectively. Mean preoperative Gleason score was 5.8 (range 3 to 8). Once recognized the rectal defect was closed laparoscopically in 2 layers and tested for the absence of leakage. Broad-spectrum intravenous antibiotics were given for 7 days. Oral liquids were started the day after surgery with a low residue diet, and a regular diet was started on postoperative day 5. Healing of the vesicourethral anastomosis was confirmed by voiding cystourethrogram on postoperative day 5.ResultsAll patients underwent a non-nerve sparing procedure except 1 in whom unilateral neurovascular bundle preservation was done. Of 13 injuries 11 were diagnosed and repaired intraoperatively, and 2 were diagnosed postoperatively. Of the 11 cases of intraoperative diagnosis and repair 9 healed primarily without colostomy and peritonitis was diagnosed in the remaining 2 on days 3 and 4, respectively. Of the latter 2 patients 1 required repair of a small rectal defect without colostomy while the other required colostomy. Colostomy was performed in the 2 patients with delayed diagnosis on days 3 and 4 but even then a rectourethral fistula developed in 1, necessitating secondary repair. Average urethral catheterization time was 8.6 days for the 9 patients with an uneventful immediate postoperative course and mean hospital stay was 6.8 days. For the remaining 4 patients urethral catheterization duration was 12, 13, 15 and 120 days, and hospital stay was 7, 16, 21 and 27 days, respectively. There was no perioperative mortality.ConclusionsRectal injury during laparoscopic radical prostatectomy requires meticulous intraoperative repair in 2 layers, which allows primary healing without diversion colostomy. For injury prevention scrupulous attention is required during non-nerve sparing radical prostatectomy, particularly at the posterior surface of the prostatic apex.
