Nine patients are described with jaundice, upper abdominal pain and ma
laise attributable to dextropropoxyphene hepatotoxicity. In each case
the history was suggestive of large bile duct obstruction. All patient
s underwent ultrasound examination and percutaneous liver biopsy. Thre
e patients also underwent endoscopic retrograde cholangio pancreatogra
phy. The histological features of the biopsies concur with previously
reported cases of dextropropoxyphene hepatotoxicity. The histological
changes seen on biopsy were remarkably constant, consisting of centril
obular cholistasis, portal tract inflammation and bile duct abnormalit
ies, in all cases mimicking large bile duct obstruction. Fifteen previ
ous patients with probable dextropropoxyphene hepatotoxicity have been
described. The occurrence of 9 further cases at one centre, 6 present
ing within 12 months, suggests that it is much more common than previo
usly assumed and may be misdiagnosed as large bile duct obstruction.
