PORTAL BILIOPATHY^-www.drkeyurbhatt.in*

Bile duct obstruction due to portal biliopathy in extrahepatic portal hypertension: surgical management.

BACKGROUND:

Varices can develop in and around the bile duct in the presence of portal hypertension, especially when it is caused by extrahepatic portal vein thrombosis. The term 'portal biliopathy' is used to describe changes in the bile duct due to these varices, which may cause bile duct obstruction. This paper reviews experience of the surgical management of patients with symptomatic portal biliopathy.

METHODS:

Nine patients with extrahepatic portal vein obstruction with symptomatic portal biliopathy. were reviewed retrospectively.

RESULTS:

Eight patients presented with jaundice, two had abdominal pain and one had recurrent cholangitis. Endoscopic retrograde cholangiography revealed abnormality of the bile duct wall, with stricture in eight patients and bile duct calculi in two. Portasystemic shunting relieved jaundice in five of seven patients, and in two a second-stage hepaticojejunostomy was required.

Conclusion: Symptomatic biliary obstruction in patients with extrahepatic portal hypertension may be relieved by a portasystemic shunt. Rarely biliary bypass may be required and is rendered safer by previous portasystemic shunting to decompress the pericholedochal varices. A direct approach to the biliary tract without a preliminary shunt may be hazardous and is frequently unnecessary.

Biliary changes in extrahepatic portal venous obstruction: compression by collaterals or ischemic? - - - called as PORTAL HYPERTENSIVE BILIOPATHY^-www.drkeyurbhatt.in*

Abstract

BACKGROUND:

The postulated mechanisms of biliary abnormalities in extrahepatic portal venous obstruction (EHPVO) are either extrinsic compression by collaterals or ischemic injury due to venous thrombosis. If the former hypothesis is correct, then biliary changes should revert to normal after portasystemic shunt surgery.

METHODS:

Five patients with EHPVO who underwent portasystemic shunt surgery were studied. One of these patients had obstructive jaundice due to portal cavernoma. Endoscopic retrograde cholangiography (ERC) was performed before as well as after the shunt surgery. Doppler ultrasound and splenoportovenography were obtained to confirm the diagnosis of EHPVO as well as shunt patency.

RESULTS:

All patients had biliary abnormalities on pre-shunt ERC. The post-shunt ERC showed partial reversal of biliary abnormalities in 3 patients, complete reversal in 1 patient, and no reversal in 1 patient. Smooth strictures opened after shunt surgery and proximal dilatation disappeared in most patients. The indentations and caliber irregularities disappeared after shunt surgery, whereas angulations and ectasias of biliary ducts persisted.

CONCLUSION:

Shunt surgery results in regression of some of the biliary abnormalities and relieves biliary obstruction, suggesting that mechanical

compression by collaterals is the mechanism behind biliary abnormalities in EHPVO. However, some biliary changes persist after shunt surgery signifying fixed obstruction due to ischemia or fibrous scarring. Thus, the two theories are not mutually exclusive.
