Diagnostic Yield of OMOM Capsule Endoscopy for Suspected Small Intestinal Lesions

Mohan Khadka  
【摘要】:BACKGROUND: Capsule endoscopy (CE), Pillcam CE (Given imaging, Yoqneam, Isreal) is a superior non-invasive tool in the diagnosis of suspected small bowel lesions to conventional modalities. In this study, we would like to share the experience with OMOM Capsule endoscopy (Jinshan Science and Technology Company, Chongqing, China). Aim: To evaluate the efficacy of OMOM CE Objectives: 1) To find out and compare the diagnostic yields of the CE for obscure gastrointestinal bleeding (OGB) and unexplained abdominal pain and/or diarrhea. 2) To see the cost effectiveness and quality of the CE Methods: Wireless video capsule endoscopy examination by using smart capsule endoscope OMOM was conducted in consecutive 46 (24 males, 22 females) with suspected small intestinal lesions in authors’center during a year period and was retrospectively reviewed. Since CE examination failed in 1 case, only 45 patients were taken in consideration for statistical analysis. The indications for CE were: OGB, unexplained abdominal pain and/or diarrhea. Results: Abnormal findings were revealed in 42 patients out of whom 36 patients were found to have significant abnormal findings in small bowel. CE was failed to pass pylorus in one patient who was suffering from OGB. Overall diagnostic efficacy of the CE was 80% excluding 6 non significant findings. Diagnostic yield of CE was significantly higher for OGB indications (26/27) in comparison to unexplained abdominal pain and/or diarrhea indications (10/18) (96.30% vs 55.55%, P 0.001). Angioectasia was the major finding for OGB cases. Active bleeding sites were observed in 8 cases. No abnormal findings were disclosed in 2 cases of unexplained abdominal pain predominant and 1 case of overt OGB. No complications were observed with the CE examination. CONCLUSION: OMOM CE has high diagnostic yield for OGB and unexplained abdominal pain or diarrhea and effectiveness is comparable with Pillcam CE.
