Abstract: Intestinal failure（IF）is the reduction in intestinal mass or function below the minimal amount necessary for adequate digestion，absorption and appropriate growth in children. It leads to the inability to maintain nutritional，fluid，and electrolyte status while consuming a regular oral diet.These children will depend on enteral nutrition（EN）and parenteral nutrition（PN）support.We need pay more attention to the complications which occured during treatment，such as intestinal failure associated liver disease（IFALD），catheter-related bloodstream infections（CRBSI），small intestinal bacterial overgrowth（SIBO）and micronutrient deficiency.

Key words: intestinal failure, nutrition, complications
