Abstract：Objective To study the diagnostic method of obscure gastrointestinal bleeding(OGIB) and etiological analysis of OGIB.Methods The clinical data of OGIB were retrospectively analyzed.Endoscopy (including gastroscopy,colonoscopy,laparoscopy,endoscopy and capsule endoscopy),air barium double contrast radiography,angiography and hemorrhage were analyzed.Results In 205 patients with benign disease etiology,lesions in the intestine were 74.15％ (152/205).Vascular lesions accounted for 38.54％ (79/205) ; tumor accounted for 20％ (41/205) ; inflammatory lesions was 11.71％ (24/205) ; diverticulum accounted for 5.37％ (12/205) ; intestinal polyps was 2.44％ (5/205) ; hookworm was 2.44％ (5/205) ; the other was 6.34％ (13/ 205) ; unexplained bleeding was 13.66％ (28/205) ; capsule endoscopy diagnosis rate was 67.1％ (94/140).The abdominal CT enhancement diagnosis rate was 30.6％ (22/72) ; double-balloon enteroscopy diagnosis rate was 63.2％ (12/19) ;selective arteriography diagnosis rate was 75.0％ (9/12) ; double contrast radiography diagnosis rate was 14.3％ (1/7) ; enterography diagnosis rate was 16.7％ (1/6).Conclusion Obscure gastrointestinal bleeding needs a high success rate of diagnosis.
