Rad Predictors for WON

July 20, 2019 updated by: Washington University School of Medicine

Radiological Predictors of Failure of Endoscopic Therapy or Need For Multiple Endoscopic Procedures in Patients With Walled Off Pancreatic Necrosis

This is a retrospective chart review study examining 1) demographic data such as age, sex, etiology of pancreatitis 2) clinical data including radiological characteristics of walled off pancreatic necrosis, walled off necrosis related admissions and readmission following endoscopic drainage, surgical or percutaneous procedures performed for the management of walled off pancreatic necrosis, and clinical outcomes following treatment of WON (including hospital readmissions, WON resolution, procedure complications, WON related death) 3) endoscopy data including indication for initial endoscopic drainage and subsequent endoscopic procedures performed for management of walled off necrosis (including additional EGD's, endoscopic drainage procedures, and/or necrosectomy)

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.

Study Type

Study Type

Describes the nature of a clinical study. Study types include interventional studies (also called clinical trials), observational studies (including patient registries), and expanded access.
Observational

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

15 years and older (Adult, Older Adult)

Accepts Healthy Volunteers

No

Genders Eligible for Study

All

Sampling Method

Non-Probability Sample

Study Population

Patients with organized collections that contain both solid and liquid debris and arise from necrotizing pancreatitis, referred to as walled off pancreatic necrosis (WON)

Description

Inclusion Criteria:

  • Patients over 18 years of age who underwent endoscopic drainage of walled off pancreatic necrosis
  • Patients who did not require further intervention (either surgical, percutaneous, or endoscopic) following endoscopic drainage
  • Patients who required further intervention for walled off pancreatic necrosis (either surgical, percutaneous, or endoscopic) following endoscopic drainage.
  • Patients who underwent percutaneous or surgical interventions prior to endoscopic drainage

Exclusion Criteria:

  • Pancreatic pseudocysts without any solid debris
  • Under 18 years of age at the time of endoscopic drainage

Cohorts and Interventions

Group / Cohort

Group / Cohort

A group or subgroup of participants in an observational study that is assessed for biomedical or health outcomes.
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.
Less than median number necrosectomies
Group one includes patients who underwent less than median number necrosectomies
Procedure: endoscopic drainage of walled off pancreatic necrosis
transmural drainage and mechanical debridement of solid debris (necrosectomy)
At least the median number of necrosectomies
Group two includes patients who underwent at least the median number of necrosectomies
Procedure: endoscopic drainage of walled off pancreatic necrosis
transmural drainage and mechanical debridement of solid debris (necrosectomy)

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
Identify WON imaging characteristics on cat-scan
Time Frame: through study completion, an average of 260 days
Characteristics on cat-scan that are predictive of requiring multiple endoscopic procedures, percutaneous drainage, and/or surgical intervention for management of walled off pancreatic necrosis
through study completion, an average of 260 days
Endoscopic course (total number and type of endoscopic treatments required for resolution of walled off necrosis, occurrence of treatment related complications)
Time Frame: through study completion, an average of 260 days
Imaging classification method to efficiently report these imaging characteristics
through study completion, an average of 260 days
Clinical course (number of hospital readmissions during treatment, rates of walled off necrosis resolution, rates of walled off necrosis related death)
Time Frame: through study completion, an average of 260 days
Characteristics to develop a predictive model that will help to identify patients at high risk for requiring multiple endoscopic procedures, percutaneous drainage, and/or surgical intervention for management of walled off pancreatic necrosis.
through study completion, an average of 260 days

Study record dates

These dates track the progress of study record and summary results submissions to ClinicalTrials.gov. Study records and reported results are reviewed by the National Library of Medicine (NLM) to make sure they meet specific quality control standards before being posted on the public website.

Study Major Dates

Study Start (Actual)

Study Start

The actual date on which the first participant was enrolled in a clinical study. The "anticipated" study start date is the date that the researchers think will be the study start date.
July 14, 2017

Primary Completion (Actual)

Primary Completion

The date on which the last participant in a clinical study was examined or received an intervention to collect final data for the primary outcome measure. Whether the clinical study ended according to the protocol or was terminated does not affect this date. For clinical studies with more than one primary outcome measure with different completion dates, this term refers to the date on which data collection is completed for all the primary outcome measures. The "anticipated" primary completion date is the date that the researchers think will be the primary completion date for the study.
September 1, 2017

Study Completion (Actual)

Study Completion

The date on which the last participant in a clinical study was examined or received an intervention/treatment to collect final data for the primary outcome measures, secondary outcome measures, and adverse events (that is, the last participant's last visit). The "anticipated" study completion date is the date that the researchers think will be the study completion date.
