Abstract
AIM: There is a paucity of data on pregnancies in women with stomas due to inflammatory bowel disease (IBD). The aim of this study was to assess stoma, IBD, obstetric and neonatal outcomes in pregnant patients with IBD and a stoma. METHOD: Multicentre retrospective audit in 15 UK hospitals. Pregnancy, stoma and neonatal outcomes were elicited from routinely collected hospital records. RESULTS: Data on 82 pregnancies from 77 patients (mean age 31.4 years, 60.9% Crohn's disease, 35.4% ulcerative colitis, 3.6% IBD-U) were included. Stoma types included ileostomy in 72 (88%) and colostomy in 10 (12%) women. There was one reported miscarriage, one still birth and 80 live births. Delivery occurred in 58 cases by caesarean section (CS), of which 44 were performed electively and 14 as emergency CS. The overall CS rate was 73%. Premature delivery before week 37 occurred in 19% and birth weight <2,500 g in 17%. Significant stoma related complications occurred during 20 (24%) pregnancies and included stoma prolapse in nine cases (2 required surgery), parastomal hernias in three cases (2 required surgery) and small bowel obstructions in seven cases (3 required surgery). CONCLUSIONS: Pregnancy for women who previously had stoma formation for IBD is associated with higher rates of caesarean section and stoma complications. Future prospective studies should capture data, including patient reported outcomes, to gather a full picture on the impact of pregnancy after stoma surgery for IBD.
