Balloon Catheter vs. Basket Catheter for Endoscopic Bile Duct Stone Extraction

December 13, 2016 updated by: Anhui Provincial Hospital

Balloon Catheter Versus Basket Catheter for Endoscopic Bile Duct Stone Extraction in Patients With Periampullary Diverticulum:a Multicenter Randomized Trial

Endoscopic bile duct stone (BDS) removal is a well-established treatment; however, the preference for basket or balloon catheters for extraction is operator-dependent It is reported that complete endoscopic treatment with a single catheter is more likely when choosing a balloon catheter over a basket catheter for extraction of BDSs≤10mm. However, a study comparing the two catheter types in patients with periampullary diverticulum has not been performed, and there is no strong basis on which to recommend the balloon catheter as a first-line stone removal device. The investigators therefore conducted a multicenter prospective randomized trial to compare catheter performance in patients with periampullary diverticulum.

Detailed Description

A prospective, multi-center, investigator sponsored, randomized controlled trial, 80 subjects will be randomly assigned to groups that were treated with basket or balloon catheters.

A descriptive analysis will be performed on primary endpoint, containing frequency of number and percentage of patients. A two proportion equality test will be conducted to explore whether incidence rates are different.Descriptive statistics including number (N), mean, median, standard deviation, minimum and maximum, will be produced for all continuous variables. Frequency tables of number (N) and percentage of subjects will be produced for all categorical variables.

Arms and Interventions

Participant Group / Arm
Intervention / Treatment
Experimental: Balloon catheter group
Bile duct stones extraction was carried out with a balloon catheter.
Device: Balloon catheter
Balloon stone extraction was carried out with a balloon catheter [Extractor Pro RX [M00547000, M00547010, or M00547020]; Boston Scientific,Shang hai,China). The Extractor Pro has multiple sizes (9-12, 12-15, and 15-18mm), the choice being made on the basis of the CBD diameter. It has a contrast-injection hole above the balloon for the performance of balloon occlusion cholangiography (BOC).
Active Comparator: Basket catheter group
Bile duct stones extraction was carried out with a basket catheter.
Device: Basket catheter
Basket stone extraction was performed with a basket catheter (Flower Basket V [FG-V435P or FG-V425PR]; Olympus Corp., Shang hai,China).

What is the study measuring?

Primary Outcome Measures

Outcome Measure
Measure Description
Time Frame
The primary endpoint is the rate of complete clearance of the duct in two groups.
Time Frame: The primary end point was the rate of complete removals of stones within 10 min.
It has a contrast-injection hole above the balloon for the performance of balloon occlusion cholangiography (BOC). For balloon stone extraction, clearance was confirmed if no residual stones remained after the final BOC and balloon sweep. For basket stone extraction, duct clearance by the basket catheter was judged to have been completed when no filling defect was found. Complete clearance of the duct by the basket catheter was defined as no filling defect (other than air) on BOC after a balloon sweep.
The primary end point was the rate of complete removals of stones within 10 min.

Secondary Outcome Measures

Outcome Measure
Measure Description
Time Frame
Secondary endpoints is the rate of adverse events such as perforation, pancreatitis,cholangitis,hyperamylasemia and bleeding.
Time Frame: Secondary endpoints is the rate of adverse events at 24 h after ERCP.
If the serum amylase of patients elevation and 3 times higher than the normal values after ERCP 24 hours in patients, who also have clinical symptoms, without other acute abdominal diseases,such as gastrointestinal perforation,acute cholecystitia and acute cholangitis and etc. In this condition, it will be defined PEP(post-ERCP pancreatitis). Hyperamylasemia will be defined as the serum amylase 3 times more than the upper normal values, without clinical symptoms. During the study, any unexpected medical issue will be called adverse event.
Secondary endpoints is the rate of adverse events at 24 h after ERCP.
