Stapled transanal rectal resection for the treatment of rectocele associated with obstructed defecation syndrome: a large series of 262 consecutive patients.

Abstract

This study aims to investigate functional results and recurrence rate after stapled transanal rectal resection (STARR) for rectocele associated with obstructive defection syndrome (ODS). A study was conducted on patients with ODS symptoms associated with symptomatic rectocele ≥ 3cm on dynamic defecography who had STARR at our institution between 01/2007 and 12/2015. Data were prospectively collected and analyzed. ODS was evaluated using the Wexner constipation score. Primary outcomes were functional results, determined by the improvement in 6-month postoperative Wexner constipation score, and 1-year recurrence. Secondary outcomes were operative time, time to return to work, pain intensity measured using the visual analogue scale (VAS), patient satisfaction, and overall postoperative morbidity and mortality at 30days. Two-hundred-sixty-two consecutive female patients [median age 54years (range 20-78)] were enrolled in the study. The median duration of follow-up was 79months (range 30-138). Sixty (23%) patients experienced postoperative complications, but only 9 patients required reinterventions for surgical hemostasis (n = 7), fecal diversion for anastomotic leakage (n = 1), and recto-vaginal fistula repair (n = 1). Only 1 intraoperative complication (stapler misfire) was reported, and there were no deaths. There was a statistically significant (p < 0.001) reduction in the median (range) Wexner constipation score from 19 (14-24) preoperatively to 9 (5-15) 6months postoperatively. Only 10 (4%) patients experienced recurrence and only 3 of them required additional reintervention. Patient satisfaction at 1year was excellent in 86%, good in 13%, and poor in 1% of patients. STARR is a safe, effective, and minimally invasive technique for the treatment of rectocele associated with ODS.
