Bile Duct Drainage After ERCP Failure: EUS-BD vs PTBD

Active, not recruiting
Conditions
Pancreatic Cancer
Biliary Obstruction
Cholangiocarcinoma
Registration Number
NCT05519605
Lead Sponsor
Radboud University Medical Center
Brief Summary

The vast majority of patients with distal biliary, pancreatic head or uncinate process cancer have jaundice caused by distal malignant obstruction (DMO) of the common bile duct. Biliary drainage by Endoscopic Retrograde Cholangiopancreatography (ERCP) with trans-papillary stent placement is the treatment of choice.

ERCP has a failure rate ranging from 12 - 25 percent. Percutaneous transhepatic biliary drainage (PTBD) is the alternative conventional way to drain the biliary tree after ERCP failure, which is related with substantial morbidity (62%) and mortality (17%). Endoscopic ultrasound (EUS)-guided biliary drainage (EUS-BD) is a novel promising drainage modality with reported excellent outcomes in terms of clinical success and complications.

The implementation of EUS-BD besides ERCP and PTBD into Dutch daily clinical practice raises many questions related to performance, costs, QoL, training, implementation and overall oncological treatment success. This structured learning/proctoring program with an additional national registry provides insights into EUS-BD and how to implement EUS-BD in the Dutch standard of care.

Detailed Description

The study is designed as a prospective multicenter registry. The data obtained in this study will enable the EUS-BD procedure to progress to larger multicenter and preferably randomized control trials.

Primary Outcome Measures
NameTimeMethod
Complications of PTBD vs EUS-BD180 days

The primary outcome measure is a composite of severe complications occurring within 180 days following inclusion, analyzed by intention to treat. Complications we score are: bleeding, perforation, biliary leak, biliary peritonitis, abscess, haemobilia, stent occlusion, cholangitis, pancreatitis, anesthesia related complications, severe post-procedural pain, drain/stent dysfunction, cutaneous fistula, stent migration and drain leakage or dislocation.

Secondary Outcome Measures
NameTimeMethod
Stent/drain patency180 days

Stent/drain patency is measured by the interval (days) between the time of stent placement and stent/drain malfunction or patient death.

Technical success of the initial procedure180 days

Defined as: the ability to access and drain the bile duct by placement of a stent/drain.

Clinical success180 days

A post-intervention reduction of bilirubin below 35 umol/L or a significant decline, so that chemotherapy could be administered at the discretion of the oncologist. Serum bilirubin is routinely measured as part of clinical practice after biliary drainage.

Treatment delay180 days

For each severe complication, the treatment team will be asked whether the complication would alter (delay or modify) the pre-existing treatment plan

Effect of EUS-BD and PTBD on the difficulty of surgery.180 days
Length of hospital stay180 days

Split into total admission days, length of initial admission and total duration of subsequent admissions; an out-patient procedure performed at the hospital is counted as one admission day

Time to re-intervention and number of re-interventions180 days
Successful training180 days

Successful training defined as significant progress in learning curve calculated by a CUSUM-analysis
