Aim: Pregnant women with Crohn's disease (CD) or ulcerative colitis (UC) are likelier to undergo Cesarean delivery than women without IBD. Active perianal disease is the only IBD-related indication for Cesarean delivery. We sought to identify clinical factors contributing to these high rates.
Methods: We conducted a retrospective cohort study of 369 pregnant women with IBD who delivered at our institution between 2006 and 2014. We used logistic regression to identify clinical predictors of Cesarean delivery.
Results: The Cesarean delivery rate among women with CD and UC were 52% and 48%, respectively. Thirty of Cesarean deliveries (54%) in CD and UC patients were performed emergently, respectively. Among those with CD, the strongest predictors of Cesarean delivery were history of perianal disease (adjusted odds ratio [aOR), 13.6; 95% CI: 3.87-47.5) and prior Cesarean delivery (aOR, 22.2; 95% CI: 6.16-80.2). Among women who underwent Cesarean delivery because of perianal disease, only 42% had active perianal symptoms during pregnancy. In UC patients, history of colectomy was a predictor of Cesarean delivery (aOR, 5.08; 95% CI: 1.95-13.2). Cesarean delivery increased the postpartum length of stay by 1.1 days on average for both CD and UC patients, reflecting a 57% and 90% increase over vaginal delivery after adjusting for confounders.
Conclusions: The decision to perform Cesarean delivery for women with IBD is complex involving IBD-related and obstetric factors and is ideally made by a multidisciplinary team that includes input from a gastroenterologist and obstetrician.
