Percutaneous Placement of Biliary Metallic Stents in Patients with Malignant Hilar Obstruction: Unilobar versus Bilobar Drainage

Crisscross-Configured Dual Stent Placement for Trisectoral Drainage in Patients with Advanced Biliary Hilar Malignancies

“…Fluoroscopically and endoscopically guided T-or Y-configured stent placement have gained widespread acceptance as bilobar internal drainage methods (2)(3)(4)(5)(6). T-and Y-configured stent placement creates two intrahepatic limbs of the stent assembly to connect one right sectoral duct and the LHD.…”

“…PERCUTANEOUS palliation with metallic endoprostheses is the accepted method to relieve malignant biliary hilar obstruction (1)(2)(3)(4)(5)(6)(7)(8)(9)(10)(11). Although the necessity of complete biliary drainage remains controversial, it seems certain that drainage of as much of the liver as possible is prudent (3)(4)(5)(6)(7)(8).…”

“…Although the necessity of complete biliary drainage remains controversial, it seems certain that drainage of as much of the liver as possible is prudent (3)(4)(5)(6)(7)(8). Many reports regarding bilobar biliary stent implantation have been published (2)(3)(4)(5)(6). T-and Y-configured stent placement involves two intrahepatic limbs connecting one right-sector duct and the left hepatic duct (LHD) to the common bile duct (CBD).…”

Triple metallic stenting in hilar malignant biliary obstructions

“…In the sixth month, the cumulative patency rate was 50%. Overall, mean primary patency rates in different series were between 141 and 231 days (8)(9)(10)(11)(12)(13)(14)(15). In the study by Maybody et al (10), an overall mean primary patency rate of 227.7 days was found in patients with multiple noncoaxial stents.…”

“…Percutaneous biliary interventions in the setting of malignant biliary obstructions are safe and effective techniques to relieve obstructive symptoms in the case of unresectable tumors (1)(2)(3)(4)(5)(6)(7)(8)(9). The percutaneous approach is the preferred method, especially for high-level obstructions, or for low-level obstructions in which previous endoscopic approaches have failed.…”
