Obesity as a risk for the recurrence of anterior vaginal wall prolapse after anterior colporrhaphy.

OBJECTIVE

To determine whether obese body mass index is associated with the recurrence of anterior vaginal wall prolapse after anterior colporrhaphy.

METHODS

We conducted a retrospective cohort study of the risk of recurrent anterior prolapse 6 months after anterior colporrhaphy in normal weight/overweight versus obese women from January 2004 to December 2010. Women who underwent a concurrent apical prolapse procedure were excluded. Data were abstracted regarding sociodemographics, physical examination, operative reports, and postoperative follow-up visits.

RESULTS

Of 282 subjects 192 (68%) were normal/overweight and 90 (32%) were obese. Median time of follow-up was 1.8 months (interquartile range [IQR] 1.4-6.2) in the normal/overweight group and 2.0 months (IQR 1.4-5.9) in the obese group. The overall risk of recurrent prolapse was 15.2%. In bivariate analysis there was a trend towards higher recurrence in the obese versus the normal/overweight cohort (21.1% vs. 12.5%, p = 0.06). In the logistic regression model, which adjusted for age, race, diabetes, constipation, cigarette use, concurrent sling, and prior hysterectomy, obesity became significantly associated with recurrent anterior prolapse (odds ratio 2.5, 95% confidence interval 1.2-5.3).

CONCLUSIONS

The risk of recurrence after anterior colporrhaphy is relatively high in the short-term. Obesity is associated with increased odds of anatomic recurrence of anterior vaginal wall prolapse.
