The objective is to study the long-term outcomes of posterior colporrhaphy with composite polyglactin 910-polypropylene mesh (Vypro 2, Ethicon, Somerville, NJ, USA) utilizing an overlay technique. Seventy-eight patients involved in our previous study were contacted 3 years after their initial operation for follow-up (Lim YN, Rane A, Muller R, Int Urogynecol J 16:126-131, 2005). Thirty-seven (47%) returned for follow-up and completed a standardized questionnaire survey, whereas a further 16 (20%) returned their postal questionnaires. Mean age was 61.3 (SD 10.8) years, and follow-up was 35.7 (SD 4.5) months. There were statistically significant improvements in vaginal lump sensation and constipation (p < 0.001) but no differences with defecatory difficulties or dyspareunia. De novo dyspareunia was reported in 27%. On examination, the incidences of mesh vaginal erosion and rectocele recurrence were 30% and 22%, respectively. It appears that posterior colporrhaphy incorporating Vypro 2 mesh with an overlay method is associated with unacceptably high incidence of complications.
