Arm: to analyze the epidemiology, prognosis and treatment of those diagnose
d as having cholangiocarcinoma of the extrahepatic biliary tree.
METHODS: a prospective study including all cases diagnosed over a period of
26 months. Fifteen patients with primary bile duct carcinoma were included
.
RESULTS: the incidence rate was 3.23 cases/10(4). The tumor locations were:
40% proximal bile duct, 33% distal bile duct, and 27% mid-duct. The treatm
ents used were: curative resection in 1 case (7%); palliative surgery in 3
cases (20%); internal drainage through a prosthetic biliary stent by endosc
opic retrograde cholangiopancreatography in 6 cases (40%) and by percutaneo
us transhepatic cholangiography in 2 cases (13%); external bile drainage in
case (7%), and in the remaining 2 patients (13%) no treatment was possible
. The 1-month, 6-month and 10-month survival rates were 67%, 40% and 33% re
spectively. Factors associated with a worse survival in this study were age
over 70 years and female sex. The worst prognostic location was the mid-du
ct compared to the distal and proximal thirds.
CONCLUSIONS: the incidence of the primary bile duct carcinoma is high in ou
r population. The commonest location is the proximal bile duct. Curative su
rgical resection is possible in only a few cases, and thus the overall prog
nosis is very bad.
