Method: progression description analysis. Results: Among 84 patients, the male/ female ratio was 1.96/1, the mean age of male patients was lower than that of female patients and there was a difference in the causes of bleeding by gender. There were 39.3% of patients with history of GI bleeding of unknown cause, 35.7% of patients with chronic diseases and 7.1% of patients taking anticoagulants and NSAIDs. In patients with black stools, the rate of lesions located in the distal duodenum and jejunum was 70.9%, higher than that of blood stool at 37.9%. Patients with moderate and severe blood loss on clinical manifestations accounted for 38.1% and on hemoglobin test accounted for 82.1%. There were 81.0% of patients requiring red blood cells transfusion. Computed tomography detected small intestinal lesions in 37.5% of patients.
