Intralesional Steroid Injection Versus Oral Prednisolone in Prevention of Esophageal Stricture

July 30, 2020 updated by: Instituto do Cancer do Estado de São Paulo

Prospective, Randomized Trial of Intralesional Steroid Injection Versus Oral Prednisolone in Prevention of Esophageal Stricture After Endoscopic Submucosal Dissection

Endoscopic resection of superficial esophageal neoplasms is already a reality and presents important advantages when compared to esophagectomy as fewer complications and better quality of life. However, extensive resections can lead to difficult-to-manage stenoses. There are several therapies available in order to prevent this stenosis but, to date, there is no definition of the gold standard.

The objective of this study was to compare the use of intralesional steroid injection versus oral prednisolone after endoscopic submucosal dissection and to evaluate the stenosis rate, number of dilations to resolve the stenosis and complications.

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 resection of superficial esophageal neoplasms is widely used as an alternative to esophagectomy, since it is less invasive, besides presenting good clinical results. Compared with esophagectomy, patients submitted to endoscopic resection present shorter hospitalization time, lower incidence of complications and better quality of life in the long term.

However, repair of esophageal ulcer, caused by endoscopic resection, which occupies three quarters or more of the circumference of the organ, can result in the formation of stenosis.

In the past, there was no consensus on the use of preventive therapies for esophageal stenosis after extensive ESD. However, Oliveira et al recently demonstrated through systematic review and meta-analysis that the use of these therapies reduces the rate of stenosis (40% on average), decreased the number of dilations to resolve the stenosis (8 sessions less ), Without altering the number of complications.

Theoretically, corticosteroids are the most appropriate choice due to their mechanism of action, modulating wound healing by preventing inflammation, by reducing prolyl hydroxylase, which helps reduce collagen production.

However, treatment with corticosteroids, especially at high oral doses, can cause several adverse effects, such as immunosuppression, diabetes, psychiatric disorders, osteoporosis, optic lesion and peptic ulcer. Thus, the use of local corticosteroid injection could minimize these side effects. However, local injection implies risks of bleeding and perforation, and is of limited use in patients receiving anticoagulant or antiplatelet therapy.

The objective of this study was to compare the local corticosteroid injection and the use of oral corticosteroids to prevent stenosis after extensive submucosal endoscopic resection of superficial esophageal carcinoma, in relation to the stenosis rate, number of dilations necessary to resolve the stenosis and frequency of complications.

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.
