title: [Study on diagnosis of small intestinal hemorrhage].
abstract: To explore the etiology and different methods of diagnosis for 33 cases of small intestinal hemorrhage, which were confirmed by surgery and/or pathology.
  
  
  METHODS
  33 cases of small intestinal hemorrhage were diagnosed by endoscopy, barium studies, radionucleotide scanning, angiograpy, exploratory laparotomy and intraoperative colonscopy, which were confirmed by surgery and/or pathology.
  
  
  RESULTS
  Small intestinal tumors were found in 13 cases (39.39%), Leiomyoma in 8; infectious diseases in 8(24.24%); Meckel's diverticulum in 7(21.21%); and vascular malformation in 3(9.1%) and others in 2(6.06%). Among them, black stool (42.42%) is the most commonly seen. The common clinical presentation was middle-anemia and patients with unexplained abdominal pain (36.36%). Radionucleotide scanning was positive in 5 out of 7 cases, and all of five were Meckel's diverticulum. Endoscopy revealed 5 out of 20 cases. Exploratory laparotomy was performed in 6, 3 were found to have some lesions, and the other 3 were diagnosed by intraoperative colonscopy.
  
  
  CONCLUSIONS
  Tumor is the nost common cause of small intestinal hemorrhage, mied anemia and black stool are the common clinical presentations, Radionucleotide scanning is one of the most useful diagnostic methods for Meckel's diverticulum and intraoperative colonscopy could elevate veracity of diagnosis.
