Forty-two patients with the postcholecystectomy syndrome were studied by
endoscopic retrograde cholangiopancreatography (ERCP). Both the biliary
ductal system and pancreatic duct were well visualized in all patients. The
ERCP was abnormal in 22 patients (52%). Abnormal findings included
choledocholithiasis, papillary stenosis, pancreas divisum, pancreatic
carcinoma, sclerosing cholangitis, incomplete cholecystectomy, and chronic
pancreatitis. The results of one or more standard liver function tests
and/or other noninvasive tests were abnormal in 36 patients; however, none
reliably predicted the presence or specific anatomical type of
pancreaticobiliary tract disease. Our data indicate that ERCP is essential
in the diagnosis and management of the postcholecystectomy syndrome. The
high yield of abnormal findings amenable to surgical correction in patients
with recurrent biliary tract symptoms following cholecystectomy justifies
the use of this procedure in all such patients.
