EPLBD With Limited EST vs. EPLBD for Choledocholithiasis

August 13, 2023 updated by: Jianfeng Yang

A Comparison of Limited Endoscopic Sphincterotomy With Endoscopic Papillary Large Balloon Dilation vs. Endoscopic Papillary Large Balloon Dilation for Endoscopic Choledocholithiasis

Endoscopic papillary balloon dilation (EPBD) for choledocholithiasis is known to be comparable to endoscopic sphincterotomy (EST) especially in cases of small stones. With larger stones (> 10 mm), EPBD with conventional balloon, which have a diameter of 6-8 mm, was reported as less effective for extraction of stones, requiring additional mechanical lithotripsy (ML). The present study aims to compare the efficacy and safety of limited EST plus endoscopic papillary balloon dilation (EST-EPBD) with endoscopic papillary large balloon dilation for large choledocholithiasis.

Conditions

Conditions

The disease, disorder, syndrome, illness, or injury that is being studied. On ClinicalTrials.gov, conditions may also include other health-related issues, such as lifespan, quality of life, and health risks.

Intervention / Treatment

Intervention / Treatment

A process or action that is the focus of a clinical study. Interventions include drugs, medical devices, procedures, vaccines, and other products that are either investigational or already available. Interventions can also include noninvasive approaches, such as education or modifying diet and exercise.

Detailed Description

ERCP is the best option to remove bile duct stones. It can be done by either endoscopic sphincterotomy (EST) or endoscopic papillary balloon dilation (EPBD). Large bile duct stones appear to be more difficult to remove with conventional methods, such as EST and EPBD. Therefore, extraction of large bile duct stones may require mechanical lithotripsy (ML) as an adjunctive procedure. The primary complication of ML is basket and stone impaction, which can lead to complications such as pancreatitis and cholangitis. Some recent studies have reported the efficacy of endoscopic papillary large balloon dilation (EPLBD) alone or combined with limited EST, establishing it as a safe treatment for the removal of large bile duct stones. The investigators conducted the present study to compare the therapeutic outcome and complications between EPLBD alone and limited EST plus EPLBD for the treatment of large bile duct stones.

Enrollment (Estimated)

Enrollment

The number of participants in a clinical study. The "anticipated" enrollment is the target number of participants that the researchers need for the study.

Phase

Phase

The stage of a clinical trial studying a drug or biological product, based on definitions developed by the U.S. Food and Drug Administration (FDA). The phase is based on the study's objective, the number of participants, and other characteristics. There are five phases: Early Phase 1 (formerly listed as Phase 0), Phase 1, Phase 2, Phase 3, and Phase 4. Not Applicable is used to describe trials without FDA-defined phases, including trials of devices or behavioral interventions.

Participation Criteria

Researchers look for people who fit a certain description, called eligibility criteria. Some examples of these criteria are a person's general health condition or prior treatments.

Eligibility Criteria

Eligibility Criteria

The key requirements that people who want to participate in a clinical study must meet or the characteristics they must have. Eligibility criteria consist of both inclusion criteria (which are required for a person to participate in the study) and exclusion criteria (which prevent a person from participating). Types of eligibility criteria include whether a study accepts healthy volunteers, has age or age group requirements, or is limited by sex.

Ages Eligible for Study

18 years to 80 years (Adult, Older Adult)
