Jeon CH, et al. - This work was planned to compare the clinical effectiveness of percutaneous stent placement between T and criss-cross configuration techniques in patients with advanced malignant hilar biliary obstruction. Researchers observed that the two techniques had comparable early clinical effectiveness; however, additional intervention is occasionally required for drainage of an undrained sector after T-configured stent placement. Longer stent patency was evident when the placement was performed with criss-cross configuration technique than T-configuration technique.
