ABSTRACT
Objective To study on the clinical application and value of double-balloon video en teroscopy in diagnosing small inlestinal bleeding. Methods Fifty-four cases with suspected small intestinal bleeding were subjected to double-balloon video enteroscopy, via the mouth and /or anus in 21, 20 and 13 cases respectively, the procedure was performed under X-ray monitoring. Results The positive rate of en-doscopy was 90. 7% , the findings were isolated or multi small intestinal ulcer 11 cases, Crhon' s disease 7 cases; chronic nonspecific inflammation 6 cases, entero-mesenchymoma 6 cases; high differentiated adeno-carcinoma 3 cases; polyps 2 cases, lymphoma 1 case, stero-pro-nematodiasis 2 cases, ancylostomiasis 2 cases, vascular deformity 2 cases ( 1 with active hemorrhage) , Michael diverticulosis 2 case, iliac polydivertic ulosis 1 case, ulcerative colonitis 1 case, duodenal stasis I case, duodenal ulcer 2 cases and essentially normal 5 cases. Complications related to the procedure never occurred. Conclusions The main causes of small intestinal bleeding are benign ulcers and tumor, as well as chronic inflammation. Parasitosis is the fourth cause. Diverticulosis and vascular deformity are the rare cause. But Michael diverticulosis is an important cause for the children with small intestinal bleeding., Double-balloon video enleroscopy is the most valuable method in diagnosing small intestinal diseases.
