Abstract Background: We compared two types of stents in patients who underwent surgery for hepatic hilar malignancies. Methods: Twenty‐one patients with hepatic hilar malignancies who underwent hepatectomy were randomly assigned to one of two groups. A 5‐Fr silicon drain with an internal lumen and side holes was used for the hepaticojejunostomy in one group (intraluminal stent group), and a 10‐Fr silicon drain with channels along the sides was used in the other (channel stent group). Results: Leakage developed in four patients (36.4%) in the intraluminal stent group versus two (20.0%) in the channel stent group. Cholangitis developed in three patients with leakage (27.3%) in the intraluminal stent group versus no patient in the channel stent group. After operation, the times required for the serum alkaline phosphatase and total bilirubin levels to return to the normal range were significantly shorter in the channel stent group (5.3 ± 2.9, 3.8 ± 2.2 days) than in the intraluminal stent group (17.0 ± 5.8, 9.4 ± 5.7 days) ( P < 0.0001, P = 0.0093). Conclusion: A 10‐Fr silicon drain with channels is superior to a 5‐Fr silicon drain with an internal lumen for internal biliary stenting of hepaticojejunostomy in patients with hepatic hilar malignancies.
