Prophylactic PS Placement to Prevent Pancreatitis After Endoscopic Transpapillary GPC for Cholelithiasis With Concomitant Choledocholithiasis

May 14, 2026 updated by: Qilu Hospital of Shandong University

Prophylactic Pancreatic Stent Placement to Prevent Pancreatitis After Endoscopic Transpapillary Gallbladder-preserving Cholecystolithotomy for Cholelithiasis With Concomitant Choledocholithiasis

In this multicenter, randomized trial, patients with cholelithiasis with concomitant choledocholithiasis based on inclusion and exclusion criteria will be randomly assigned to receive rectal indomethacin alone or the combination of indomethacin plus a prophylactic pancreatic stent after endoscopic transpapillary gallbladder-preserving cholecystolithotomy.Clinical data and patient-reported outcomes are regularly collected at baseline and during follow-up periods. The study aims to analyze the impact of pancreatic duct stent implantation on the incidence of post-ERCP pancreatitis in gallstone patients treated with ERCP-GPC by comparing the efficacy differences between the experimental and control groups. Additionally, the study investigate the effects of pancreatic duct stent placement post-ERCP on other postoperative complications, conduct a comparative analysis of the economic benefits of placing versus not placing pancreatic duct stents after ERCP, and develop effective clinical strategies for preventing pancreatitis after gallbladder-preserving stone extraction in gallstone patients.

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

  • Adult
  • Older Adult

Accepts Healthy Volunteers

No

Arms and Interventions

Participant Group / Arm

Participant Group / Arm

A group or subgroup of participants in a clinical trial that receives a specific intervention/treatment, or no intervention, according to the trial's protocol.
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.
Other: Receive rectal indomethacin alone
Drug: rectal indomethacin alone
rectal indomethacin was used alone in the control group
Experimental: Combination of indomethacin plus a prophylactic pancreatic stent
Device: Prophylactic pancreatic stent
All procedure-related interventions except for the administration of rectal indomethacin and placement of a prophylactic stent were left to the discretion of the endoscopist.During ERCP, once eligibility was confirmed, patients were randomized in a 1:1 ratio to receive a prophylactic stent or not.In patients assigned to the indomethacin plus stent group, endoscopists were expected to attempt stent placement, although the technical approach, including the amount of time and effort expended for this purpose, was not standardized.All patients received 100mg indomethacin suppositories.

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
The Proportion of Patients with Post-ERCP Pancreatitis
Time Frame: 24 hours to 72 hours after ERCP
If a patient exhibits two out of the following three characteristics, a diagnosis of postoperative pancreatitis is made: (1) Abdominal pain consistent with acute pancreatitis, (2) Serum amylase and/or lipase levels at least three times the upper limit of normal, and (3) Abdominal imaging studies showing radiological changes consistent with acute pancreatitis.
24 hours to 72 hours after ERCP

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.

The severity was defined as mild post-ERCP pancreatitis resulting in a hospitalization of ≤3 days, moderate post-ERCP pancreatitis resulting in a hospitalization of 4-10 days, and severe post-ERCP pancreatitis resulting in a hospitalization of > 10 days, or leading to the development of pancreatic necrosis or pseudocyst, or requiring percutaneous or surgical intervention.
