Clinical abnormalities in adults with pancreaticobiliary maljunction with and without bile-duct dilatation.
OBJECTIVE
To study clinical diseases associated with pancreaticobiliary maljunction with or without bile-duct dilatation.


METHODS
A retrospective study over 16 years.


METHODS
A single university surgical service in Japan.


METHODS
Thirty-three patients with pancreaticobiliary maljunction.


METHODS
Gallstones and cancer in patients with and without bile-duct dilatation.


RESULTS
Twenty-five patients had dilatation of the bile duct, 8 did not. Seven (28%) of the 25 patients with bile-duct dilatation had gallstones compared with 1 (12%) of the 8 patients with no dilatation. Seven (88%) of the 8 patients with no dilatation had carcinoma (all of the gallbladder), but only 3 (12%) of the 25 patients with bile-duct dilatation had carcinoma (1 of the gallbladder, 2 of the bile duct).


CONCLUSIONS
Prophylactic cholecystectomy is recommended for patients with pancreaticobiliary maljunction and no dilatation of the bile duct because of the high incidence of gallbladder cancer.
