Abstract
The majority of benign strictures of the
extrahepatic bile ducts results from operative
damage during the course of chelecystectomy and
are potentially avoidable. With early surgical
repair, the prognosis is good, but delay in the
treatment allows a sequence of events to develop
which terminates in sclerosing cholangitis,
biliary cirrhosi~t portal hypertension, liver
failure and death( 70).
High biliary stenosis, resulting from the
technical difficulties that challenge surgeons
require the creation of ingenious technical
maneuvers by specialists in order to relief
cholestasis in these group of patients. Thus,
smith (176) described the mucosal graft technique.
In his long experience with this procedure, he had
an 85% rate of good results after a 2 year followup(
176).
According to Bismuth< 110l, the mucosal graft
technique is performed blindly without direct
visualisation of the biliary tract, and the dome
of the eneteric mucosa placed inside the biliary
tract may possibly occlude the ductal branches
that dr~in important segment of the liver.
Blumgart1 177l described 20 patients who required
reoperation after a mucosal graft technique had
been performed at other hospitals.
The fact is that the aforementioned
has not been universally accepted
treatment of benign high stenosis of
biliary tract.
