Surgery Due to Inflammatory Bowel Disease During Pregnancy : Mothers and Offspring Outcomes From an Ecco Confer Multicentre Case Series (Scar Study)

i) To evaluate the evolution of pregnancies and offspring after inflammatory bowel disease (IBD) surgery during pregnancy; and ii) to describe the indications, the surgical techniques, and the frequency of caesarean section concomitant to surgery.Patients operated on due to IBD during pregnancy after 1998 were included. Participating clinicians were asked to review their databases to identify cases. Data on patients' demographics, IBD characteristics, medical treatments, IBD activity, pregnancy outcomes, surgery, delivery, foetal and maternal outcomes, were recorded.Forty-four IBD patients were included, 75% had Crohn's disease. Eighteen percent of the surgeries were performed in the 1 st trimester, 55% in the 2 nd, and 27% in the 3 rd trimester. One patient had complications during surgery, and 27% had postsurgical complications. No patient died. Seventy percent of deliveries were carried out by caesarean section. There were 40 newborns alive and 4 miscarriages/stillbirths (1 in the 1 st, 2 in the 2 nd, and 1 in the 3 rd trimester): 2 occurred during surgery, and another 2 occurred 2 weeks after surgery. Fourteen percent of the surgeries during the 2 nd trimester and 64% of those in the 3 rd trimester ended up with a simultaneous cesarean section or vaginal delivery. Of the 40 newborns, 61% were premature, and 47% had low birth weight; 42% of newborns needed hospitalisation (25% in the intensive care unit).IBD surgery during pregnancy remains an extremely serious situation. Therefore, surgical management should be performed in a multidisciplinary team, involving gastroenterologists, colorectal surgeons, obstetricians and neonatal specialists
