Rectocele is often associated with chronic constipation. Various surgical techniques have been described to repair rectoceles, but the results vary. The aim of this study was to compare the outcomes of transanal repair (TAR) and transanal repair with posterior colporrhaphy (TAR + PC).


While 44 patients underwent TAR, 49 patients underwent TAR + PC for surgical repair of rectocele. Patients were followed up 3 months post-surgery for anorectal physiological changes. From the entire cohort of patients who underwent the surgical repair, 22 patients who underwent TAR and 25 patients who underwent TAR + PC agreed to participate in the 3-year post-treatment check-up.


Out of the 22 patients who underwent TAR, 3 patients (13.6%) scored more than 15 on the constipation scoring system (CSS), while 1 out of 25 patients who underwent TAR + PC scored more than 15 on the CSS 3 months post-treatment, which is considered as recurrence (p = 0.237). With 7 patients from the TAR group (31.8%) and 2 patients from the TAR + PC group (8.0%) showing recurrence of rectocele at 3-year post-treatment follow-up, this study found that TAR + PC had a much lower rate of recurrence than TAR. Furthermore, TAR + PC was found to be more effective than TAR in terms of rectal sensation, sensory threshold (p = 0.001), and early defecation urge (p = 0.003).


TAR + PC can help alleviate some symptoms by restoring the rectal sensation and improving the rectovaginal septum. It can be inferred that the addition of a simple treatment method can lead to a lower rate of recurrence.
