Reconstruction of the rectovaginal septum with a W-mesh for rectocele

Abstract

Aim: to assess of late results of original method of rectocele repair with non-absorbable polypropylene W-form mesh. Patients and methods: the pilot study included 37 patients which underwent surgery for rectocele repair using original technique of W-mesh. The late results were assessed in 21 (56.6 %) of them ≥ 6 month after surgery. Before the surgery and 6 months after, patients underwent a clinical assessment of symptoms. Specialized questionnaires for assessment of constipation (Colonic evacuation disorder scale, PFDI-20, Cleveland Clinic Constipation Score) were used. Defecography and anorectal manometry were performed before and in 6-months after surgery for evaluation of pelvic floor disorders. Results: no obstructive defecation symptoms were revealed in 85.7% of patients 6 month after surgery.In ≥ 6 months after surgery all questionnaires showed decrease in scores by more than 2 times. Comparison of the results before and 6 months after the surgery showed significant differences for all questionnaires (p < 0.0001). According to defecography performed before and after the surgery a significant reduction (p < 0.05) of rectocele depth, time of rectal voiding (decreased by 1.5 times) and residual volume of contrast agent (decreased by 2.5 times) were revealed. There are no severe complications requiring re-operation were observed. Conclusion: transvaginal mesh repair of symptomatic rectocele demonstrated good clinical results 6 months after surgery. Good results were revealed in 85,7 % of patients confirmed by specialized questionnaires and defecography.
