Persistent site-specific defects after reconstructive pelvic surgery

Abstract

Our objective was to determine the persistence rates of site-specific defects after reconstructive pelvic surgery. We conducted a retrospective analysis of the post-operative outcome for 77 patients with pelvic support defects. Forty-five patients in the abdominal group underwent a Burch procedure, paravaginal repair and sacral colpopexy when indicated; 32 patients in the vaginal group had a sacrospinous vault fixation with or without colporrhaphy. A chi2 test, Wilcoxon's two-sample test. Wilcoxon's signed-rank test and multivariate logistic regression model were used for data analysis. The two groups were similar in age, weight, parity and menopausal status. There was significant improvement of all defects except in the vaginal group, which showed a higher rate of persistent paravaginal defects (68.7 vs. 13.3%, P = 0.001). After adjusting for potential confounders, there was no difference in the rates of apical and anterior wall defects between the two groups. The odds ratio for persistent paravaginal defects in the vaginal group was 8.9 (95% CI: 2.3-34). The choice of surgical procedure is the most important factor determining the rate of persistent pelvic support defects. Lateral wall defects must be addressed at the time of reconstructive surgery.
