Outcomes of Abdominal Apical Suspension Using Mesh in a Tertiary Training Hospital: A Seven-year Retrospective Review.

Abstract

Background: Pelvic organ prolapse (POP) is an inconvenience that can affect a woman's well-being. Reconstructive pelvic floor surgery involves repairing defects in the endopelvic fascia and pelvic floor musculature as close to the physiologic and anatomic norm. The cornerstone of successful prolapse repair is a strong apical support.

Objective: The aim of the study is to determine the outcomes of abdominal sacrocolpopexy (ASC) and abdominal sacrohysteropexy (ASH) in the Philippines.

Methods: The study utilized a descriptive study design to compare the pre-operative and post-operative Pelvic Organ Prolapse Quantification Score (POP-Q Score), presence of mesh complications, and urinary/bowel symptoms in patients operated within 2010-2016 in a Philippine tertiary training hospital. Based on recovered charts and inclusion/exclusion criteria, this study sampled 34 of 50 patient records. Statistical measures of median and range were used to describe pre-operative and post-operative POP-Q scores in any two follow-ups within 6-, 12-, 18-, and 24-month interval. The objective success rate and incidence of urinary/bowel symptoms were described using frequencies and percentages. Presence of any mesh erosion was noted for each follow-up. McNemar's test was applied to assess the comparative occurrence of each symptom comparing between the pre-operative and first follow-up periods.

Results: ASC had a success rate of 73.7% at six months and 56.3% at 12 months post-surgery. ASH showed an 84.6% success rate at six months and 71.4% at 12 months. Apical support has a 97% success rate without affecting the anterior or posterior compartments. Out of 20 ASC patients, 5 (25%) exhibited anterior compartment descent, whereas two out of 14 ASH patients (14.2%) had the same condition. It is observed that the anterior vaginal wall has the higher tendency to descend after reconstructive surgery, independent of route or technique. In addition, not all patients with surgical prolapse beyond -1 experienced symptomatic vaginal bulges. Overall, a notable decrease in the occurrence of urine symptoms was seen after the surgery. No mesh erosion was seen within the initial two years of follow-up but there was a single reported instance of abdominal hernia, an uncommon consequence.

Conclusion: This study demonstrated that ASC and ASH have good success rate in apical support; however, descent of the anterior or posterior compartment diminishes the overall success rate in terms of over-all objective POP-Q score. Both resulted to improvement in symptoms with minimal complications.
