About this study
Official title: Efficacy and Safety Comparison of Balloon Catheter and Basket Catheter for Endoscopic Pancreatic Duct Stone Clearance
The aim of the study is to compare the safety and efficacy of the basket catheter with that of the balloon catheter for endoscopic extraction of pancreatic stones.
Read the detailed description
This is a retrospective cohort study. Patients with chronic pancreatitis who underwent ERCP for pancreatic duct stone extraction using either a basket or a balloon catheter were enrolled in this study.
- Conditions
- Chronic Pancreatitis
- Being tested
- basket catheter, balloon catheter
- Keywords
- Pancreatic stone, Endoscopic retrograde cholangiopancreatography (ERCP), Basket catheter, Balloon catheter, Stone clearance
- Medical subject headings
- Pancreatitis, Chronic
What participants receive
What participants receive. In a randomised study each person is assigned to one group by chance.
basket catheterDevice
Stone extraction is completed with either a basket or balloon catheter at the time of ERCP. The basket catheter is made of nickel-titanium wires which can be manipulated to trap and withdraw stones.
balloon catheterDevice
Stone extraction is completed with either a basket or balloon catheter at the time of ERCP. The balloon catheter is made of latex, which is inflated after passing the stone, thus pushing the stone outwards.
What is being measured
The primary outcome is the main question the study is designed to answer.
the rate of stone clearance in basket and balloon catheter groups
complete clearance, defined as fragmentation of the pancreatic stones to < 3 mm and clearance of more than 90% of the fragments; partial clearance, defined as clearance of 50-90% of the fragments; and unsuccessful clearance, defined as the presence of pancreatic stones ≥ 3 mm or clearance of less than 50% of the fragments.
Measured: 1 year after ERCP
Secondary outcomes (1)
the rates of ERCP peri-procedural outcomes and the rates of complications of ERCP in basket and balloon catheter groups
ERCP peri-procedural outcomes included difficult cannulation, endoscopic sphincterotomy, dilation of stenosis, and extraction through the minor papilla. Major post-ERCP complications, which were defined according to the Consensus Criteria, included post-ERCP pancreatitis (PEP), bleeding, infection, perforation, and basket impaction
Measured: 1 year after ERCP

How can a doctor refer a patient or contact the research team?
The record lists no contact. The official record names the sponsor, who can be asked directly. AzTrials does not enrol participants or take referrals.
What does the primary outcome measure?
the rate of stone clearance in basket and balloon catheter groups (time frame: 1 year after ERCP). It is what the study was designed to measure, not a finding.
Where can I read the original study information?
Does a listing mean the treatment is approved or proven to work?
No. A listing means the study is registered. It does not show that the treatment is safe, works, or is approved by a regulator.
How often is this information updated?
