Nationwide Trends of Bowel Obstruction and Intussusception in Endometriosis Patients [11H]

INTRODUCTION: One of the complications of endometriosis rarely described is bowel obstruction (BO). The purpose of our study was to evaluate the incidence of BO among women with endometriosis, the trend and the demographic characteristics. METHODS: We used the data from the Healthcare Cost and Utilization Project—Nationwide Inpatient Sample (HCUP-NIS). We studied women with endometriosis aged 15 to 55-years from 2005-2014. Those with neoplasms in the genitourinary or gastrointestinal system were excluded. RESULTS: Of a total 278,613 women with endometriosis, 1386 had BO or intussusception resulting in an overall incidence of 0.5%. Although the number of hospital admission related to endometriosis were decreasing, there was a significant increase in the incidence of bowel obstruction/intussusception during the time period from 0.3% to 0.9%. Moreover, women with BO tend to be white and with higher income ( P <.05). The incidence of BO in those with endometriosis in the pelvic/peritoneum and the intestine were comparable. Also, those with BO tend to have lower BMI ( P <.05). In addition, there was no association between diabetes mellitus, hypertension, dyslipidemia or hospital region, and the incidence of BO. CONCLUSION: Although there is a downtrend in the incidence of hospital admission related to endometriosis, the incidence of endometriosis specifically in the intestine or the rectovaginal wall as well as the incidence of bowel obstruction has been slightly increasing.
