b) It can present as choledocho duodenal fistula

c) There is complete biliary obstruction which  leads to marked jaundice and pruritis

d) MRCP and other other cholangiography can be diagnostic

Answer c

In recurrent pyogenic cholangitis (RPC)  complete obstruction does not occur and jaundice and pruritis is not marked.  RPC is a disease commonly seen in young Asians (also known as oriental cholangiohepatitis) which leads to multiple strictures in extra or intrahepatic ducts.

Association with Ascaris lumbricoides and Clonorchis sinensis has been noted.

It can present as choledocholithiasis  with stricture, choledochoduodenal fistula, acute pancreatitis, secondary biliary cirrhosis and can lead to cholangiocarcinoma.

MRCP can be diagnostic and is preferred because of its non invasive nature.
