Abstract |
To evaluate the role of hepatobiliary (DISIDA) scan in
the diagnosis of biliary obstruction, we studied the
clinical characteristics of 9 cases with biliary
obstructuon, whose hepatobiliary scans and
ultrasonography were not concordant (normal
ultrasonography and abnormal hepatobiliary scan). The
results were as follows; 1) The main chief complaints
(89%) were abdominal pain, especially in RUQ area. The
levels of serum bilirubin were elevated in 67% of
patients (normal∼5.9 mg/dl) and those of alkaline
phosphatase were elevated in 78% of patients
(normal∼724 U/L). 2) The final diagnoses were CBD
stones (67%), tumor (22%) and 3 cases were associated
with C. sinensis. 3) The major obstruction sites were
in distal CBD (89%). From the above results we
concluded that hepatobiliary scan is a useful
diagnostic method of biliary obstruction, especially in
distal CBD lesion and early stage, in spite of normal
ultrasonography. |
