“…64 There were minor complications of self-limiting hemobilia in one patient and rapidly resolving cholangitis in three patients. Similar outcomes have been demonstrated with silicone covered nitinol Y-configured stents (EGIS Biliary KEY stent; S&G Bio, Seoul, Korea) 65 and self-expandable nitinol stents (8.5F, Niti-S Biliary Y-type, Taewoong Medical). 66 Generally, complication rates during Y-configured stent placement are low with the technical success achieved in most cases.…”

Various minimally invasive percutaneous interventions may be performed for the treatment and management of malignant biliary obstruction. The types of percutaneous interventions include percutaneous transhepatic biliary drainage, percutaneous cholecystostomy, and biliary stent placement. Biliary stents have undergone continued evolution in design to prolong patency, increase cost-effectiveness, improve patient survival, and quality of life. Furthermore, investigational techniques, such as radiofrequency ablation, intraluminal brachytherapy, and photodynamic therapy promise new technologies in the field of biliary intervention. This review focuses on the current status of percutaneous therapies for malignant biliary strictures and obstruction.

“…Stent-in-stent deployment was the most common method, in which a second stent is placed through the mesh of the first stent. In these cases, the mesh in the middle portion of the stent is necessarily looser and therefore more likely to allow tumor ingrowth and occlusion [ 6 ]. Bile duct stents manufactured in China are constructed using metal wires of thicker gauge (0.16 mm) than that used in South Korean stents (0.12 mm), which results in reduced stent compliance [ 7 ].…”

We report a case in an inoperable patient with type IV Klatskin tumor treated by the use of a novel, two piece, Y-configured self-expandable metallic stent (SEMS) combined with two 125I seed strands via bilateral approach. The placement of the Y-shaped SEMS was successful and resulted in adequate biliary drainage. After 2 months of intraluminal brachytherapy (ILBT), both 125I seed strands and temporary drainage catheter were removed after patency of the expanded stents was confirmed by the cholangiogram. This technique was feasible and could be considered for the treatment of patients with Bismuth type IV Klatskin tumors.

“…The silent and insidious clinical features of MOJ lead to a low immediate surgery rate (10-20%) and a poor post-resection survival rate (1)(2)(3)(4)(5). An unresectable stage with poor prognosis is frequently seen in many patients, and the primary aim is to relieve pruritus, cholangitis, pain, and jaundice (2,6). Thus, stent implantation in the obstructive biliary duct is the preferred palliation modality for such patients (7)(8)(9).…”

Background: Malignant obstructive jaundice (MOJ) has a low immediate surgery rate (10-20%) and a poor post-resection survival rate. Although several clinical results have demonstrated the safety and efficacy of stent placement combined with radioactive seeds, the existing implantation methods are time consuming and prone to error. In this study, we introduced a self-made delivery system and novel implantation method for a self-expandable metallic stent (SEMS) with 125 I seed strand and evaluated its feasibility and efficacy in MOJ patients.Methods: Our self-made delivery system was applied to 61 patients (39 males and 22 females, mean age 66.36±10.73 years) from October 2018 to June 2020 in our center with a novel implantation method. The preparation and manipulation processes were described in detail. Technical and clinical successes were recorded, and stent patency and overall survival (OS) were assessed. A P value of less than 0.05 indicated a significant difference.Results: Stents with 125 I seed strands were successfully placed in all 61 participants with our novel implantation method. The clinical success rate was 96.7%, and no severe procedure-related complications were found except bile leakage through puncture in 1 participant. The median duration of primary stent patency was 120 (37, 233.5) days, and the median OS was 169 (41, 270) days.Conclusions: Our self-made delivery system with a novel SEMS implantation method with 125 I seed strand was feasible and effective for MOJ patients and significantly simplified the current implantation approach.
