Portal Cavernoma Cholangiopathy in Children and the Management Dilemmas

Portal cavernoma cholangiopathy (PCC) is one of the most harrowing complications of extrahepatic portal venous obstruction, as it determines the long-term hepatobiliary outcome. Although symptomatic PCC is rare in children, asymptomatic PCC is as common as that in adults. However, there are major gaps in the literature with regard to the best imaging strategy and management modality in children. Moreover, natural history of PCC and effect of portosystemic shunt surgeries in children are unclear. Neglected PCC would lead to difficult or recalcitrant biliary strictures that will require endoscopic therapy or bilioenteric anastomosis, both of which are challenging in the presence of extensive collaterals. There are limited studies on the effect of portosystemic shunt surgeries on the outcome of PCC in children compared to adults. In this review, we aimed to collate all existing literature on PCC in childhood and also compare with adult studies. We highlight the difficulties of this disease to provide a comprehensive platform to foster further research on PCC exclusively in children.
