Bile duct wall calcification: A rare entity in portal cavernoma cholangiopathy

Cavernomatous transformation of the portal vein, seen in extrahepatic portal venous obstruction (EHPVO), can cause impingement or ischemic insult on bile ducts manifesting as "portal cavernoma cholangiopathy" (PCC). Bile duct wall calcification in portal biliopathy is a rare occurrence and has not been reported in the literature to the best of our knowledge. We report a 59-year-old male, a known case of EHPVO, who had undergone laparoscopic cholecystectomy, splenectomy, and splenorenal shunt in the past. The patient had now presented to us in view of recurrent episodes of cholangitis for which a bilioenteric bypass was planned. Intraoperatively, dilated and densely thickened bile ducts with multiple pericholedochal collaterals were noted. Incision of common hepatic duct and left hepatic duct showed completely calcified ductal wall with no visible healthy mucosa. Calcifications were removed partially from the bile duct walls near choledochotomy site. With the anticipation of futile benefit from bilioenteric bypass, Roux-en-Y HJ was abandoned. Hepaticoduodenostomy was done to prevent bile leak from choledochotomy site.
