If Chronic Gallbladder Diseases Increase the Incidence of PEC

December 13, 2025 updated by: Wenbo Meng, Hepatopancreatobiliary Surgery Institute of Gansu Province

If Chronic Gallbladder Diseases Increase the Occurence of Post Endoscopic Retrograde Choledochopancreatography Choledocholithiasis（a Prospective Multi-center Cohort Study)

This is a prospective, multi-centre trial conducts at 4 ERCP centers in China designed to determine if chronic gallbladder diseases increase the incidence of Post-Endoscopic Retrograde Choledochopancreatography-Choledocholithiasis (PEC)

Study Overview

Status

Status

Indicates the current recruitment status or the expanded access status.
Completed

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

Endoscopic Retrograde Choledochopancreatography(ERCP) has the advantages of less injury and faster recovery for common bile duct stone patients. However, according to our retrospective study, ERCP will has a mostly 10% possibility to get an acute purulent cholecystitis which often requires emergency intervention, when patients combined with chronic gallbladder diseases, such as chronic cholecystitis, asymptomatic gallstones, and gallbladder wall thickness, the incidence of PEC will increase accordingly. The aim of this study is to observe if chronic gallbladder disease will increase the occurence of PEC and develop a high-risk PEC model.

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 90 years (Adult, Older Adult)

Accepts Healthy Volunteers

What is the study measuring?

Primary Outcome Measures

Primary Outcome Measures

In a clinical study's protocol, the planned outcome measure that is the most important for evaluating the effect of an intervention/treatment. Most clinical studies have one primary outcome measure, but some have more than one.
Outcome Measure
Measure Description
Time Frame
Number of Acute PEC(post-ERCP-cholecystitis )
Time Frame: 1month
When the PEC occurs, with right upper abdominal pain, White Blood Cell increasing, gallbladder wall ≥4mm or crudely, temperature might be more than 38 degree centigrade
1month

Secondary Outcome Measures

Secondary Outcome Measures

In a clinical study's protocol, a planned outcome measure that is not as important as the primary outcome measure for evaluating the effect of an intervention but is still of interest. Most clinical studies have more than one secondary outcome measure.
Outcome Measure
Measure Description
Time Frame
Number of Pancreatitis
Time Frame: 1month
Typical abdominal pain, with the level of serum amylase increasing at least 3 times of the normal range within 24 hours after ERCP.
1month
Number of Cholangitis
Time Frame: 1 month
Temperature should be more than 38 #, right upper abdominal pain, chills or WBC≥10
1 month
Number of Perforation
Time Frame: 1 month
Typical abdominal pain,abdominal muscle tension, tenderness, evidence of free gas in abdominal cavity
1 month
