Improvements in Self-Reported Depression Following Treatment of Fecal Incontinence with Sacral Neuromodulation.

Objective: To evaluate changes in self-reported depression after treatment of fecal incontinence (FI) with sacral neuromodulation.

Materials And Methods: This is a subanalysis of data collected from March 2016 to October 2017 for an Institutional Review Board-approved retrospective cohort study. Demographic information, medical history, psychiatric comorbidities, and the Patient-Reported Outcomes Measurement Information System item bank t-scores were extracted from the electronic medical record. The differences in t-scores were compared with a two-sided paired t-test, and a p value <0.05 was considered statistically significant.

Results: Of the cohort (n = 24), most were Caucasian (88%), female (92%), nonsmokers (92%). Median age was 63.5 years (interquartile range 57.5-71.0 years) and median body mass index was 27.7 kg/m (range 18.3-42.9 kg/m ). A significant decrease in mean depression t-scores occurred after implantation of a sacral neuromodulation device, -4.5 (95% confidence interval [CI]: -8.7, -0.2, p = 0.04). Self-reported pain interference (p = 0.37) and physical function (p = 0.47) scores were similar following implantation. Individuals with comorbid anxiety reported the greatest improvement in depression (-6.5, 95% CI: -11.8, -1.1, p = 0.02).

Conclusions: Treatment of FI with sacral neuromodulation was associated with improvement in self-reported depression with the greatest improvement in those with anxiety. Further prospective research is needed to corroborate these findings.
