Long-term outcomes of synthetic transobturator nonabsorbable anterior mesh versus anterior colporrhaphy in symptomatic, advanced pelvic organ prolapse surgery

Abstract

Anterior vaginal mesh (AVM) combined with sacrospinous ligament fixation (SSF) yields better long-term success rates over anterior colporrhaphy (AC) in advanced pelvic organ prolapse (POP) surgery, with a low rate of mesh-related complications. Medical records of 198 patients who underwent surgery for POP between January 2006 and March 2010 were reviewed retrospectively. Patients' assessment at baseline and third-year postoperative follow-up were analyzed. SSF plus AC or AVM was performed for apical and anterior compartment repair. Primary outcome was objective cure [Pelvic Organ Prolapse Quantification (POP-Q) stage ≤ 1)], and subjective cure defined as negative response to questions 2 and 3 on the POPDI-6. Secondary outcomes were complications, symptoms severity and quality of life as measured with validated questionnaires. Post-operative data were available for 186 patients, 72 in AC group and 114 in AVM group were analyzed. The mean age, parity and operating time in AVM group were significantly higher as compared to AC group. The overall objective and subjective cure rate in AVM group was significantly higher than AC group (90.3 % and 88.6 % versus 73.6 % and 70.8 %, with P value = 0.003 and 0.002 respectively). Mesh exposure rate was 3.5 %. Improvement in both POPDI-6 and PISQ-12 in AVM group was statistically significant compared to AC group. Transobturator synthetic nonabsorbable AVM combined with SSF yielded a favorable and sustainable result over 5 years as compared to traditional AC, both in anatomical and subjective success rate. Mesh related morbidities were low and acceptable.
