Cholangiocarcinoma (CCA) is the most common biliary malignancy and the second most common hepatic malignancy after hepatocellular carcinoma (HCC). A majority of the CCA (50-70%) was presented in the area of the biliary duct bifurcation. Recent retrospective study included heterogeneous group of malignant diseases demonstrate that draining more than 50% of was associated with a longer median survival.
However, in recent European Society of Gastrointestinal Endoscopy (ESGE) biliary stenting clinical guideline and Asia-Pacific consensus recommendations for endoscopic and interventional management of hilar cholangiocarcinoma (HCCA), whether we should deployment bilateral or unilateral metal stent for patients with HCCA was not clearly recommended due to the absence of randomized controlled trials.
Full Title of Study: “Percutaneous Bilateral Versus Unilateral Metal Stent Placement for Hilar Cholangiocarcinoma : A Prospective Open-label Randomized Controlled Trial”
- Study Type: Interventional
- Study Design
- Allocation: Randomized
- Intervention Model: Parallel Assignment
- Primary Purpose: Treatment
- Masking: None (Open Label)
- Study Primary Completion Date: December 2021
Patients with advanced hilar obstruction (Bismuth III and IV), PTBS had a higher success rate of cholestasis palliation and a low rate of post cholangitis when compared with endoscopic retrograde cholangiopancreatography(ERCP). The advantage of percutaneous approach is the precise lobar selection for drainage and this approach should yield a lower rate of cholangitis.
Guideline recommendation European Society of Gastrointestinal Endoscopy (ESGE) biliary stenting clinical guideline and Asia-Pacific consensus recommendations the goal of palliative stenting of HCCA is drainage of adequate liver volume (50% or more), irrespective of unilateral, bilateral, or multi-segmental stenting was based on heterogeneous group of malignancy by ERCP in retrospective study.There are no randomized clinical trials compared with these two internal biliary drainage methods in HCCA using metal stent.
The aim of the present study was to compare the effect and safety of bilateral versus unilateral stenting in patients with HCCA.
- Procedure: bilateral metal stent insertion
- Procedure: unilateral metal stent insertion
Arms, Groups and Cohorts
- Active Comparator: unilateral metal stent insertion
- unilateral metal stent insertion was performed either left or right hepatic lobe as can be drainage more liver volume
- Experimental: bilateral metal stent insertion
- percutaneous transhepatic biliary drainage plus bilateral metal stent.The bare stents were used for PTBS
Clinical Trial Outcome Measures
- Failure to control jaundice or failure to prevent stent occlusion or re-jaundice within three month after stent implantation
- Time Frame: From stent insertion to three months
- Median survival
- Time Frame: up to 1 year
Participating in This Clinical Trial
