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.
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.
Allocation: Randomized, Endpoint Classification: Safety/Efficacy Study, Intervention Model: Parallel Assignment, Masking: Single Blind (Subject), Primary Purpose: Treatment

In Japan and Europe, a retrieval basket is generally used for endoscopic extraction of bile duct stones, while in the US, a retrieval balloon is mainly used. However, the efficacies of these two devic...
Purpose To evaluate the effectiveness of mechanical thrombectomy with the use of a stent retriever in acute ischemic stroke, performed by using a balloon guide catheter or non-balloon guide catheter. ...
Long-term hemodialysis catheter dwell time in the central vein predisposes to fibrin sheath development, which subsequently causes catheter malfunction or occlusion. In very rare cases, the catheter c...
Nonoperative repair of occluded vessels, ducts, or valves by insertion of a balloon catheter. It is used, among other things, to treat varices, torn retinas, renal and biliary calculi, gastric, bronchial and rectal stenoses, and heart valves, and includes catheterization with Fogarty and Foley catheters.

Placement of a balloon-tipped catheter into the pulmonary artery through the antecubital, subclavian, and sometimes the femoral vein. It is used to measure pulmonary artery pressure and pulmonary artery wedge pressure which reflects left atrial pressure and left ventricular end-diastolic pressure. The catheter is threaded into the right atrium, the balloon is inflated and the catheter follows the blood flow through the tricuspid valve into the right ventricle and out into the pulmonary artery.
Use of a balloon catheter to block the flow of blood through an artery or vein.
Endovascular procedure in which atheromatous plaque is excised by a cutting or rotating catheter. It differs from balloon and laser angioplasty procedures which enlarge vessels by dilation but frequently do not remove much plaque. If the plaque is removed by surgical excision under general anesthesia rather than by an endovascular procedure through a catheter, it is called ENDARTERECTOMY.
