Surgical Management of Portal Cavernoma Cholangiopathy

The majority of patients with portal cavernoma cholangiopathy (PCC) are asymptomatic, however some (5–38%) present with obstructive jaundice, cholangitis, or even biliary pain due to bile duct stones which form as a result of stasis. Most patients with extrahepatic portal venous obstruction (EHPVO) present with variceal bleeding and hypersplenism and these are the usual indications for surgery. Those who present with PCC may also need decompression of their portosystemic system to reverse the biliary obstruction. It is important to realize that though endoscopic drainage has been proposed as a non-surgical approach to the management of PCC it is successful in only certain specific situations like those with bile duct calculi, cholangitis, etc. A small proportion of such patients will continue to have biliary obstruction and these patients are thought to have a mechanical ischemic stricture. These patients will require a second stage procedure in the form of a bilioenteric bypass to reverse the symptoms related to PCC. In the absence of a shuntable vein splenectomy and devascularization may resolve the PCC in a subset of patients by decreasing the portal pressure.
