Portal biliopathy is defined as the partial or total obstruction of the bile duct caused by the paracholedochal venous plexus dilation secondary to portal hypertension (PH). Oo et al6 reported three patients with refractory PCC in which bare metal stent placement avoided repeated ERCPs although one patient showed stent obstruction needing its removal. Our results are in accordance with previous reports showing that FCSEMS placement is safe in patients with PCC, although massive haemobilia after FCSEMS removal has been reported.10 Interestingly, all stents remained permeable when retrieved, indicating a potential benefit of using covered stents in this context. Fully covered metal stent placement as first-line endoscopic treatment for complicated portal cavernoma cholangiopathy. [Extracted from the article]
