Methods： Data from 89 consecutive patients （49 males, 40 females） with suspected small bowel disease who underwent OMOM CE （Jinshan Science and Technology Company, review. The patients＇ indications of the disease consisted of the Chongqing, China） examination were obtained by retrospective following： obscure gastrointestinal bleeding （OGIB）, abdominal pain or diarrhea, partial intestinal obstruction, suspected inflammatory bowel disease, tumor of unknown origin, hypoproteinemia, constipation, weight loss, and elevated tumor markers. Results： CE failed in one patient. Visualization of the entire small bowel was achieved in 75.0%. Capsules were naturally excreted by all patients. The detection rate of abnormalities was 70.5% for patients with suspected small bowel disease, and the diagnostic yield for patients with OGIB was higher than that for patients with abdominal pain or diarrhea （85.7% vs 53.3%, P〈0.005）. Angiodysplasia was the most common small bowel finding. Active bleeding sites were noted in the small intestine in 11 cases. Conclusion： OMOM CE is a useful diagnostic tool for the diagnosis of variably suspected small bowel disease, whose diagnostic efficiency is similar to that of the Pillcam SB （small bowel） CE （Given Imaging, Yoqneam, Israel）.展开更多
