Transperineal rectocele repair with biomesh: updating of a tertiary refer center prospective study

Literature review of the outcome of and methods used to improve transperineal repair of rectocele

BACKGROUND

Rectocele is commonly seen in parous women and sometimes associated with symptoms of obstructed defecation syndrome (ODS).

AIM

To assess the current literature in regard to the outcome of the classical transperineal repair (TPR) of rectocele and its technical modifications.

METHODS

An organized literature search for studies that assessed the outcome of TPR of rectocele was performed. PubMed/Medline and Google Scholar were queried in the period of January 1991 through December 2020. The main outcome measures were improvement in ODS symptoms, improvement in sexual functions and continence, changes in manometric parameters, and quality of life.

RESULTS

After screening of 306 studies, 24 articles were found eligible for inclusion to the review. Nine studies (301 patients) assessed the classical TPR of rectocele. The median rate of postoperative improvement in ODS symptoms was 72.7% (range, 45.8%-83.3%) and reduction in rectocele size ranged from 41.4%-95.0%. Modifications of the classical repair entailed omission of levatorplasty, addition of implant, concomitant lateral internal sphincterotomy, changing the direction of plication of rectovaginal septum, and site-specific repair.

CONCLUSION

The transperineal repair of rectocele is associated with satisfactory, yet variable, improvement in ODS symptoms with parallel increase in quality-of-life score. Several modifications of the classical TPR were described. These modifications include omission of levatorplasty, insertion of implants, performing lateral sphincterotomy, changing the direction of classical plication, and site-specific repair. The indications for these modifications are not yet fully clear and need further prospective studies to help tailor the technique to rectocele patients.

Surgery for Posterior Compartment Vaginal Prolapse: Graft Augmented Repair

Posterior compartment vaginal prolapse can be approached with multiple surgical techniques, including transvaginally, transperineally, and transanally, repaired with either native tissue or with the addition of an augment. Augment material for posterior compartment prolapse includes biologic graft (dermal, porcine submucosal), absorbable mesh (Vicryl polyglactin), or nonabsorbable synthetic mesh (polypropylene). Anatomic success rates for posterior compartment repair with augment has ranged from 54% to 92%. Augmented posterior compartment repair has not been shown to have superior outcome to native tissue repair. The focus of this article is on the transvaginal approach comparing native tissue repair with graft or mesh augmented repair.

Rectal mesh erosion after posterior vaginal kit repair

INTRODUCTION AND HYPOTHESIS

The present video shows a rare case of erosion through the full rectal wall into the rectum after a transperineal implant of a double-arm polypropylene kit.

METHODS

A 70-year-old woman underwent a transperineal implant of a double-arm polypropylene kit. One year after surgery, she developed bothersome symptoms in the posterior perineum including heaviness, pain and rectal bleeding during defecation. A clinical examination showed the presence of a part of the prothesis traversing the rectal cavity. A minimally invasive transanal approach was performed to remove the mesh and restore the rectal integrity.

RESULTS

This surgical technique demonstrates rectal mesh removal with a transanal approach.

CONCLUSIONS

To our knowledge, this is a rare complication of rectal erosion of a posterior transperineal mesh kit. The aim of this video is to show a complete transanal approach to treating this serious complication avoiding the more invasive and traumatic abdominal procedure.
