Comparison of Recurrence Rates after Anterior Colporrhaphy for Cystocele Using Three Different Surgical Techniques

Abstract

Aims: To compare the recurrence rates after anterior colporrhaphy for cystocele using three different surgical techniques: standard plicating, purse-string, and rolling anterior colporrhaphy. Methods: A retrospective chart review of women undergoing anterior colporrhaphy for cystocele with or without concomitant operations between 1988 and 2000 was conducted. Women were assessed by vaginal examination pre- and postoperatively at 6 weeks and over 2 years. Grades of cystocele were assessed by Baden-Walker halfway grading system. χ² tests and ANOVAs were performed for categorical and continuous variables, respectively. Cox regressions were used to calculate recurrent rates. Results: Among the studied 363 women, 296, 33, and 34 underwent standard plicating, purse-string and rolling techniques, respectively. There was no significant difference in age, parity, menopausal status, or mean length of follow-up among the three groups. The purse-string group revealed a significantly higher risk of recurrence than the standard plicating group (hazard ratio: 2.67; 95% CI: 1.05–6.08). The severity of cystocele was another key role of determining the prognosis for recurrences (grades 3 & 4 relative to grade 1, hazard ratio: 3.35; 95% CI: 1.34–8.38). Conclusion: Our study showed that standard plicating and rolling technique provided similar anatomic cure rates. However, the purse-string technique was less effective in restoring vaginal anatomy than standard plicating anterior colporrhaphy.
