MORPHOLOGICAL CHANGES OF THE SMALL INTESTINE IN ACUTE STRANGULATIVE INTESTINAL OBSTRUCTION IN THE STAGE OF DECOMPOSITION IN CHILDREN
Purpose. The purpose was to determine the depth and prevalence of pathomorphological changes in the small intestine of children at the distance from the visible border of necrosis with decompensated acute strangulated intestinal obstruction (ASIO) to determine the minimum possible length of intestinal resection. Material and methods. Morphological studies of a resected fragment of the small intestine were performed in 24 children aged 3 days to 18 years who had undergone a surgery for ASIO with intestinal necrosis. Strangulated adhesive obstruction was found in 17 children, five children had congenital intestine torsion and two children faced small intestinal strangulation in the congenital mesenteric defect. The postsurgical material was studied morphologically using histological stains with the distance of 3 cm between the section. Results. The depth, prevalence of the morphological changes in the small intestinal wall, intensity and length of morphological changes in children with decompensated ASIO were determined. Conclusion. A differentiated approach to the selection of resection scope in the proximal and distal directions from the visible border of ASIO-related necrosis is necessary. The distances are twice shorter in children as compared to adults. Refusal from extensive resections will enable to reduce the rate of short bowel syndrome in children.
