PURPOSE: To assess the
value of magnetic resonance (MR) cholangiopancreatography in patients
in whom endoscopic retrograde cholangiopancreatography (ERCP)
was unsuccessful or did not completely delineate ductal abnormalities.
MATERIALS AND METHODS: MR cholangiopancreatography was performed
in 37 consecutive patients because ERCP was unsuccessful (n =
20), postsurgical biliary-enteric anatomy was present (n = 10),
or evidence of complete pancreatic duct obstruction was found
ar ERCP (n = 7). RESULTS: MR cholangiopancreatography was successful
in all patients. Eleven patients had normal MR findings and required
no further intervention. Eight patients has abnormalities that
were detected with MR but were followed up clinically. Eleven
patients subsequently underwent laparotomy, three underwent therapeutic
percutaneous transhepatic cholangiography (PTC), two underwent
diagnostic (PTC), and one underwent ultrasound-guided biopsy.
CONCLUSIONS: MR cholangiopancreatography plays an important role
in the care of patients in whom ERCP is unsuccessful or incomplete
and when technical difficulties can be anticipated.
