[Effect of ileostomy on the clinical outcomes of children with very early onset inflammatory bowel disease]

To explore the effect of ileostomy on clinical outcomes of children with very early onset inflammatory bowel disease(VEO-IBD). The clinical data of 11 children with VEO-IBD who underwent ileostomy in the Department of Gastroenterology of the Affiliated Children's Hospital of Zhengzhou University from January 2016 to December 2022 were retrospectively analyzed, and the clinical characteristics and outcomes were analyzed. A total of 11 cases were included, including 7 males and 4 females, aged 3.0 (0.9, 8.0) months. The main clinical manifestations were fever and diarrhea, with L2 type the main lesion site (according to the Paris classification of childhood Crohn's disease). There were 7 cases of gene type interleukin (IL)-10RA. After VEO-IBD ileostomy, the disease site, incidence of growth disorders, the weighted children's Crohn's disease activity index, the simplified endoscopic score of Crohn's disease, and severe mucosal inflammation activity rate were all lower than those before ileostomy (all P<0.05). The postoperative inflammatory indicators and factors were lower than those before ileostomy (all P<0.05). The mucosal barrier indicators after ileostomy were increased than before (all P<0.05). The nutritional evaluation indicators after ileostomy were improved (P<0.05). Ileostomy can reduce inflammatory response of VEO-IBD, improve intestinal mucosal barrier, reduce disease activity, and improve nutritional status.
