Short bowel syndrome in pediatric patients.

The treatment of infants and children with short bowel syndrome aims at restoring the intestinal continuity and at improving the physiological process of gut adaptation. Mucosal hyperplasia allows the remaining gut to ensure an adequate digestion and an absorption process leading to intestinal autonomy. During the period of adaptation, appropriate parenteral and/or enteral feeding must be directed at maintaining an optimal nutritional status. Delay of intestinal autonomy depends on the characteristics of the residual intestine: length, presence of the ileocecal valve and colon, and motor function. Bacterial overgrowth compromises intestinal adaptation and increases the risk of liver disorders. Few patients will remain long-term dependent on parenteral nutrition. All approaches aimed at achieving intestinal autonomy should be tried: use of trophic factors, intestinal tapering, and lengthening. In a few residual patients, permanent intestinal failure or extreme short bowel syndrome require intestinal transplantation.
