Annual long-term functional outcomes after transanal repair for symptomatic rectocele.

Purpose: This study was performed to assess the long-term annual functional outcomes and quality of life (QOL) after transanal rectocele repair. Methods: We evaluated retrospectively collected data from patients who underwent transanal repair for symptomatic rectocele between February 2012 and December 2018. The Constipation Scoring System (CSS), the Fecal Incontinence Severity Index (FISI), and several QOL questionnaires (e.g., the Patient Assessment of Constipation-QOL [PAC-QOL], Fecal Incontinence QOL, and the 36-Item Short Form Survey [SF-36]) were administered before surgery and annually after surgery. Additionally, physiological assessments and defecography were performed before and after surgery. Substantial symptom improvement, indicated by at least a 50% reduction in the CSS or FISI score, was evaluated postoperatively. All postoperative follow-up results were compared with the preoperative data. Results: Thirty-two patients were included in the study. The median follow-up period was 5 years (range, 0.5-7 years). Postoperative defecography showed that the rectocele size significantly decreased (P<0.0001). However, the physiological assessment did not reveal postoperative changes. The CSS score 1 year after surgery was significantly lower than the preoperative score (P<0.0001) and remained significantly low until the long-term follow-up. Constipation improved by more than 80% 2 to 5 years postoperatively, and fecal incontinence improved in 2/3 of the patients after 5 years. The PAC-QOL scores significantly improved (all P<0.05) over time until the 3-year and long-term follow-ups, and 6 of the 8 SF-36 scores significantly improved at specific points postoperatively. Conclusion: Transanal rectocele repair provides long-term improvement for constipation and constipation-specific QOL.
