Abstract: Gastrointestinal bleeding is a common disease in children，which can be divided into upper gastrointestinal bleeding and lower gastrointestinal bleeding according to the location of bleeding. Digestive endoscopy is an important approach to diagnosing the cause of gastrointestinal bleeding.The earlier the endoscopy is conducted，the higher the diagnostic rateis. Therefore，when the hemodynamics is stable，digestive endoscopy should be performed as soon as possible. When hemodynamics is unstable，fluid resuscitation should be activated and restrictive transfusion strategy should be adopted. Adequate bowel preparation is important for the quality of colonoscopy，enteroscopy，and capsule endoscopy.In this review，we summarize the perioperative management of gastrointestinal bleeding in children，and focuses on bowel preparation.

Key words: gastrointestinal bleeding, perioperative manage-ment, bowel preparation
