Acute Pouchitis is Common in Pregnant and Postpartum Women.

Abstract

The impact of pregnancy on the development of pouchitis in women who have undergone total proctocolectomy with ileal pouch anal anastomosis for ulcerative colitis is poorly understood. This was a retrospective study of women with ulcerative colitis who underwent total proctocolectomy with ileal pouch anal anastomosis and subsequently became pregnant at Mount Sinai Hospital. The primary outcome was acute pouchitis during pregnancy or the postpartum period defined as symptoms of increased stool frequency and urgency treated with antibiotics. A total of 44 women with 63 pregnancies and complete data were identified. Acute pouchitis occurred in 14 pregnancies (22.2%) in 12 women and in the postpartum period of 10 pregnancies (15.9%) in 9 women. Acute pouchitis occurred more frequently in women with a history of acute pouchitis immediately before, during, or after pregnancy. Acute pouchitis was common during pregnancy and the postpartum period, likely due to microbial shifts. Although not statistically significant, these results provide insight into the impact of pregnancy on the risk of pouchitis and establish the framework for preconception counseling that focuses on prevention and management of pouchitis during pregnancy.
