Effect of PVE on Surgical Outcomes and Long-term Survival in Perihilar Cholangiocarcinoma

Effect of Portal Vein Embolization on Surgical Outcomes and Long-term Survival in Patients With Perihilar Cholangiocarcinoma

Portal vein embolization is often recommended to reduce the risk of postoperative liver failure and mortality. In this retrospective cohort study, researchers investigated the effect of portal vein embolization in patients with resectable perihilar cholangiocarcinoma bismuth type III and IV.

Inclusion Criteria:

1. patients with Bismuth type III or IV stricture on radiological examination, including computed tomography (CT) or magnetic resonance cholangiography
2. patients with perihilar cholangiocarcinoma histologically confirmed by surgical resection or forceps biopsy/brush cytology under endoscopic retrograde cholangiopancreatography or through the percutaneous transhepatic biliary drainage tract.

Exclusion Criteria:

1. patients with unresectable perihilar cholangiocarcinoma
2. patients who refused treatment
3. patients with other concomitant malignancies.
