Background: Intrabiliary rupture is one of the common complications of hydatid cyst of the liver, with
its possible sequel of obstruction, cholangitis and post operative biliary fistula. It should be managed
properly, with accurate pre operative diagnosis and proper surgery, both for the cyst and some sort of
biliary drainage with the available alternatives common bile duct exploration and T-tube drainage,
choledochoduodenostomy or a pre operative endoscopic sphincterotomy, the choice is a matter of
controversy.
Objectives: To evaluate three methods of biliary drainage, (T-tube, choledochoduodenostomy,or
preoparative endoscopic sphincterotomy) during management of intrabiliary rupture of hydatid cyst of
the liver, in terms of morbidity and mortality rates.
Methods: During the period between October 2001 till October 2007. 92 patients attending Baghdad
and Al-Diwaniya Teaching Hospitals, presented with symptomatic intrabiliary rupture of hydatid cyst
liver disease were included in the study, they complained from abdominal pain and jaundice, all
patients were diagnosed preoperatively by ultrasonography, CT scan and Magnetic resonance
cholangiopancreatography (MRCP) was performed in selected patients, 42 patients were selected
randomly and subjected preoperatively to ERCP and sphincterotomy, in whom it was successful in
only 36 patients. During surgery, the cyst and the associated biliary communication was managed
according to the operative circumstances. The common bile duct was explored thoroughly and cleaned
of hydatid element. In patient with CBD diameter > 20 mm side to side choledochoduodenostomy was
performed ( 7 patients ) , while T- tube drainage was performed in younger age patients with mildly
dilated CBD ( 49 patients ) . Those patients in whom a preoperative ERCP and sphincterotomy was
successful, surgery was limited to hepatic hydatid cyst only (36 patients).
Results: The overall mortality was 1.1%, the morbidity rate was significantly higher in the CD (71.4%)
and pre operative ERCP group (47.2%) than the T-tube drainage group (26.5%). There was no
significant difference in the rate of development of biliary fistula in the 3 different procedures.
Conclusion: T-tube drainage is safe and effective method of biliary drainage during the management of
intrabiliary rupture of hydatid cyst of the liver, in terms of morbidity and mortality rates. Pre operative
endoscopic sphincterotomy is good alternative in experienced hands. |
