OBJECTIVE. The diagnostic yield of enteroclysis was retrospectively ev
aluated for patients with obscure bleeding from the gastrointestinal t
ract. MATERIALS AND METHODS. A total of 128 patients with obscure gast
rointestinal bleeding were referred to our department for enteroclysis
between 1988 and 1993. The original radiologic reports were reviewed
to determine the radiographic findings in these patients. The radiogra
phic findings then were correlated with medical, surgical, and patholo
gic findings. RESULTS. Thirty-two patients had lesions found at entero
clysis. Nineteen of those patients had confirmation of the radiographi
c diagnosis, primarily by pathologic examination of the surgical speci
men. Five other patients were found at surgery to have had false-posit
ive diagnoses at enteroclysis. Eight patients ceased to bleed without
pathologic corroboration, but their clinical presentation and course s
upported the radiographic diagnosis. Thus, 27 (21%) of the 128 patient
s had confirmed or highly probable lesions seen at enteroclysis as the
cause of obscure gastrointestinal bleeding. Seventeen patients (13%)
had tumors involving the small bower, and three (2%) had arteriovenous
malformations in the jejunum. CONCLUSION. This study corroborates ear
lier reports that enteroclysis is a useful diagnostic test for examini
ng the small intestine in patients with obscure gastrointestinal bleed
