Abstract
INTRODUCTION AND HYPOTHESIS: The objective of the study was to characterize trends in lower reproductive tract fistula (LRTF) repair in inpatient US women from 1979 to 2006. METHODS: Retrospective data was obtained from the National Hospital Discharge Survey regarding LRTF diagnoses, demographics, comorbidities, and fistula repair procedures, using ICD-9-CM diagnostic and procedure codes. Age-adjusted rates (AARs) were calculated using 1990 census data. Trends in LRTF surgical repair were evaluated using regression analysis. RESULTS: Between 1979 and 2006, the AAR of LRTF repair declined from 7.8 to 4.8 per 100,000 women (b = -2.97, p < 0.001). The most common surgical fistula repairs were rectovaginal, vesicovaginal, and colovaginal. The AARs of colovaginal and vesicovaginal fistula repair remained stable, while the AAR of rectovaginal fistula repair declined. CONCLUSIONS: The AAR of inpatient LRTF repair declined between 1979 and 2006, perhaps reflecting a concurrent decrease in obstetric trauma, in the context of decreasing episiotomy and operative vaginal delivery and increasing cesarean section rates.
