Abstract:
Objective To compare the detection rates of capsule endoseopies with push endoseo-pies. Methods From May 2002 through January 2003 , thirty - nine patients with suspected small bowel diseases, particularly the gastrointestinal bleeding of unknown origin were examined by capsule endoscopies. Of the 39 patients. 32 complained of obscure recurrent gastrointestinal bleeding. From January 1993 to October 1996, 36 patients suffered from unexplained GI bleeding underwent push endoscopies. All patients had prior normal results on gastroseopy, colonoscopy, small bowel barium radiography, seintigraphy and/ or angiogra-phy. Results M2A capsule endoscopies disclosed abnormal small bowel findings in 26 out of 32 patients (81% ). Twenty one of 26 patients had significant pathological findings in explaining their clinical disorders with diagnostic yield of 66% (21 of 32 patients). Definite bleeding sites diagnosed by capsule endoscopies in 21 patients including angiodysplasia 8, inflammatory small bowel diseases 5, small bowel polyps 4, GI stro-mal tumor 2,earcinoid tumor and lipoma 1 , and bemorrhagie gastritis 1. Push endoscopies detected the definite sources of bleeding in 9 of 36 patients (25%). Definite bleeding sources included angiodysplasia 2, leiomyosareoma 2, leiomyoma 1 , lymphoma 1 , Grohns disease 1 , small bowel polyps 1 ,and adenocareinoma of ampulla 1. Suspected bleeding sources were seen with push endoscopies in two additional patients, and other five patients with capsule endoscopies. Conclusion Gapsule endoseopy is superior to push endoscopy in detecting obscure GI bleeding ( P
