Right Porto-Ovarian H-Shunt for the Surgical Treatment of Symptomatic Portal Biliopathy: A Case Report and Literature Review

Abstract

Portal hypertension, especially when it is caused by extrahepatic portal vein thrombosis, is commonly followed by the development of an abnormal periportal and pericholedochal variceal network, which form a portal cavernoma. This may exert extrinsic pressure on the adjacent biliary ducts and gallblader, causing morphologic abnormalities, termed portal biliopathy, which is usually leading to asymptomatic cholestasis, while less frequently it can be associated with obstructive jaundice, gallstone formation, and cholangitis. Endoscopic stone extraction can effectively treat portal biliopathy when cholangitis is associated with common bile duct stones. Portosystemic shunts are indicated in cases of disease recurrence as they can achieve regression of portal cavernoma and usually relieve symptomatic portal biliopathy. This case describes an alternative partial portosystemic shunt that utilizes the right ovarian vein as an autologous conduit for the surgical treatment of symptomatic portal biliopathy.
