ABSTRACT

Objective To assess the diagnostic value of capsule endoscopy (CE) and CT virtual endoscopy (CTVE) for small intestinal diseases.Methods The data of 31 patients with suspected small bowel diseases who were examined by both CTVE and CE were collected.The diagnostic rates of CE and CTVE was compared by paired data McNemar test,using the diagnosis confirmed by surgery or follow-up as the golden standard.Results The confirmed diagnosis of 31 patients were small intestinal tumor in 16,nontumorous lesion in 10 and no abnormal lesion in 5.CE identified positive findings in 24 patients,including 14 cases of tumorous lesion (with mis-location in 2 and failure in definite diagnosis in 7) and 10 cases of non-tumorous lesion.CTVE identified positive findings in 17 patients,including 14 cases of tumorous lesion (with mis-location in 1 and failure in definite diagnosis in 4) and 3 cases of non-tumorous lesion.The combination of CE and CTVE could identified positive findings in 26 patients,including 16 tumorous and 10 nontumorous lesions.The diagnostic rates of CE and CTVE for tumorous lesions were both 87.5% (14/16).The overall diagnostic rate of combined CE and CTVE was 83.9% (26/31),which was significantly higher than that of CTVE alone (54.8%,17/31) but similar to that of CE alone (77.4%,24/31).Conclusion Both CE and CTVE are effective in diagnosis of small intestinal lesions and the combined use of 2 methods can increase diagnosis yield.
