[Diagnostic values of double-balloon enteroscopy and abdominal computed tomography in small bowel disease].
OBJECTIVE
To evaluate the diagnostic values of double-balloon enteroscopy (DBE) and abdominal computed tomography (CT) in small bowel disease.


METHODS
Seventy eight DBE procedures were carried out in 70 patients, 40 males and 30 females; aged 47.7 (16 - 83) with suspected small bowel disease, all of whom received gastroscopy, colonoscopy, and abdominal CT examination at the same time. The diagnostic value of DBE was compared with that of CT.


RESULTS
Seventeen kinds of small bowel lesions were detected, mainly including Crohn's disease, adenocarcinoma, gastrointestinal stroma tumor, vascular deformity, lymphoma, diverticulum, and polyp. There were no complications and all procedures were tolerated well. The mean duration of procedure was 110 min (30 - 240 min). Nineteen patients received surgical intervention. The diagnostic yield rate of DBE was 57.1% (40/70), significantly higher than that of CT (31.4%, 22/70, P < 0.01). The positive diagnosis rate of DBE combined with CT was 62.9% (44/70), not significant different from that of the DBE alone (P > 0.05).


CONCLUSIONS
DBE shows a significantly higher diagnostic yield than CT in patients with suspected small bowel disease, and thus should be selected for the initial diagnosis. DBE Combined with CT did not increase the diagnostic yield. However, CT not only provides direction of intubation for DBE, but also clearly depicts the small bowel wall and extraenteric alterations. DBE and CT compliment each other in examining the patients with suspected small bowel disease.
