Objective:
To evaluate the results and quality of life outcomes of transperineal repair using gracilis muscle interposition in patients who were candidates for attempted preservation of bowel and bladder function. There is currently no widely accepted procedure for the treatment of complex RUF, such as those complicated by radiotherapy, previous attempts at repair, or large in size.
Methods:
Thirteen patients who underwent transperineal repair with gracilis muscle interposition for complex RUF were identified. Records were reviewed for fistula etiology, prior repair, intraoperative findings, hospital course, complications, diversion reversal, and outcome. Follow-up data were gathered from clinic visits and questionnaires.
Results:
Preoperative diagnoses included: prostate cancer (PCA) (12) and imperforate anus (1). Treatment for PCA included radical prostatectomy (4); brachytherapy (BT) (3); external beam radiation therapy (EBRT) + BT (3); cryoablation (1); and EBRT + cryoablation (1). Five patients underwent prior unsuccessful repair. There were no intraoperative complications. Postoperative complications included fecal incontinence (3) and bladder neck contracture (1). Nine patients (75%) reported some degree of urinary incontinence, with 2 patients reporting this as significant, defined as incontinence "most of the time." Suprapubic catheters were removed after 6 weeks, and median stomal reversal was at 17.5 weeks (12-28). One patient developed a recurrent RUF. All patients completed quality-of-life questionnaires assessing urinary and fecal outcome. Fecal outcome measures were generally better than urinary, but both were reasonable given the complexity of the situation.
Conclusions:
Transperineal repair with gracilis muscle interposition is an effective treatment for selected patients with complex RUF. Our experience demonstrates low morbidity, high success rates, and reasonable bowel and bladder function postoperatively.
