A long-term cohort study of surgery for recurrent prolapse comparing mesh augmented anterior repairs to anterior colporrhaphy.

BACKGROUND

There are safety concerns regarding the use of mesh in vaginal surgery with a call for long-term follow-up data. This study was designed to evaluate the long-term safety and efficacy of vaginal repairs performed for recurrent cystocele using Perigee (non-absorbable trans-obturator) mesh.

METHODS

A retrospective consecutive cohort of 48 women who underwent surgery for recurrent prolapse between March 2007 and December 2011 in a single centre was reviewed. Satisfaction was assessed using the patient global impression of improvement (PGI-I). Symptoms were assessed with the pelvic floor distress inventory (PFDI). Women were questioned regarding pain, sexual activity and pelvic floor surgery performed since the original procedure and examined for erosion. Women were compared to 25 controls from a consecutive cohort of repeat anterior colporrhapies.

RESULTS

The mean length of follow-up was 6.5 years (78 months; range 48-106). Significantly more women in the mesh group reported that they were "much better" or "very much better" (69 vs 40%  = 0.02). The rate of mesh erosion at follow-up was 11.6%. Two women in the mesh group required surgical excision of eroded mesh in the operating room (4%). The reoperation rate for a combination of de novo stress incontinence, recurrent prolapse and mesh exposure was similar in each group (33% mesh vs 32% native tissue).

CONCLUSIONS

A vaginal mesh repair using a non-absorbable trans-obturator mesh has improved satisfaction compared to an anterior colporrhaphy.
