Transvaginal posterior colporrhaphy combined with laparoscopic ventral mesh rectopexy for isolated Grade III rectocele: a prospective study of 27 patients

Aim The aim of this study was to evaluate prospectively transvaginal posterior colporrhaphy (TPC) combined with laparoscopic ventral mesh rectopexy (LVR) in patients with a symptomatic isolated rectocele. Method Patients with these complaints underwent dynamic and static MRI. All consecutive patients with a Grade III (4 cm or more) rectocele and without internal/external rectal prolapse, enterocele and external sphincter damage were operated on. The patients completed the Obstructed Defecation Syndrome (ODS) score and the Cleveland Clinic Incontinence Score (CCIS). All tests were repeated after treatment. Dynamic disorders of the pelvic floor detected by MRI were recorded. Results In 27 patients [median age 67 (46-73) years], TPC combined with LVR was feasible. Complications were limited to port site infection in two patients. Sexual discomfort (n = 8) due to prolapse diminished in six (75%) patients and in one (4%) de novo dyspareunia developed after treatment. The median follow-up was 12 (10-18) months. The median CCIS was 12 (10-16) before treatment and 8 (7-10) after (P < 0.0001). The median ODS score was 19 (17-23) before and 6 (3-10) after treatment (P < 0.0001). There was no change in urinary symptoms. Conclusion TPC combined with LVR for obstructed defaecation and faecal incontinence in patients with Grade III rectocele significantly relieves the symptoms of these disorders.
