A Trial of Esophageal and Gastric Stenting for Leak or Perforation (ESO-stent)

March 15, 2016 updated by: The Methodist Hospital Research Institute

A Phase II Trial of Esophageal and Gastric Stenting for Leak or Perforation

Long term follow-up of patients treated for esophageal fistulas with a newer occlusive self-expanding covered metal stents compared to traditional stents.

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

This study is written to evaluate our experience treating esophageal fistulas with occlusive self-expanding covered metal stents. The long-term outcomes of patients treated with this new type of stent are as yet unknown. The differences between these stents is also unknown, as well as the ease of removal, efficacy, and/or placement. The intent of this study is not to determine which stent is better, but to merely evaluate the use of both. With this in mind, there will be no randomization of stent use, nor will there be restrictions on which stent may be used in which setting. This will be left to the judgment of the clinical placing the stent.

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.

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 and older (Adult, Older Adult)

Accepts Healthy Volunteers

No

Genders Eligible for Study

All

Description

Inclusion Criteria:

  1. Patients must have radiographic or endoscopic proof of an esophageal leak or fistula.
  2. Patients will be required to undergo imaging with CT scan, endoscopy, or fluoroscopy to investigate the leak. Once the location of the leak is identified, then patients must be taken for stenting and any adjunctive treatment within 12 hours of diagnosis or within 12 hours of arrival to The Methodist Hospital.
  3. Patients must sign informed consent indicating that they are aware of the investigational nature of this study in keeping with the policies of the hospital.

Exclusion Criteria:

  1. Patients who will not agree to return for routine follow-up and studies.
  2. Patients who will not tolerate an endobronchial ultrasound or endoscopic procedure (coagulopathy [INR>1.8, PTT>60, or platelet level <50], hemodynamically unstable [MAP<50 or SBP<80], or other medical illness precluding safe endoscopy).
  3. Patients who have a perforation too high to stent (such as the back of the pharynx, where a stent is not able to be placed), the only unfavorable anatomic location is this one listed above; we believe all other locations are amenable to stent placement.
  4. Resectable carcinoma, megaesophagus, severe stricture, or caustic ingestion.

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.

  • Ultraflex, ULTRAFLEX ESOPHAGEAL NG STENT SYSTEM

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
Safety of esophageal stenting by conducting an Omnipaque swallow and by the success of leakage stops and fistula healing.
Time Frame: 15 - 30 days
By results from all procedures as reported by the surgeon conducting the stenting in relationship to difficulty and/or complications, as well as patient tolerability. When the esophagus can be sealed and any contamination drained, the stents have successfully provided coverage to allow healing of the esophageal wall.
15 - 30 days
Efficacy of esophageal stenting by the success of leakage stops and fistula healing.
Time Frame: 15 - 30 days
By results from all procedures as reported by the surgeon conducting the stenting in relationship to difficulty and/or complications, as well as patient tolerability. When the esophagus can be sealed and any contamination drained, the stents have successfully provided coverage to allow healing of the esophageal wall.
15 - 30 days
A 30 day duration of stent placement and the relation to the healing esophagus
Time Frame: 30 days
By results from all procedures as reported by the surgeon conducting the stenting in relationship to difficulty and/or complications, as well as patient tolerability. Evaluation of the healing process of the esophagus within first 30 days with the capability of its removal procedure. When the esophagus can be sealed and any contamination drained, the stents have successfully provided coverage to allow healing of the esophageal wall.
30 days

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
An institutional protocol for stent management
Time Frame: 1 year
Results will be considered for assessing and instituting an institutional protocol to become the standard of care for future patient situations.
1 year
