Dysphagia | Dysphagia in Oculopharyngeal Muscular Dystrophy (OPMD)- Evaluation, Endoscopic Examination of Swallowing, Treatment and Long Term Follow up

Dysphagia research study

What is the primary objective of this study?

The investigators aimed to review the natural history of dysphagia and dysphonia in OPMD in order to identify the best candidates and the proper timing to perform dysphagia alleviating procedures in both heterozygote and homozygote patients from the large pool of cases with this disease in Israel.

Who is eligible to participate?

Inclusion Criteria: - heterozygote and homozygote OPMD patients Exclusion Criteria:

Study Interventions

Interventions can include giving participants drugs, medical devices, procedures, vaccines, and other products that are either investigational or already available or noninvasive approaches such as surveys, education, and interviews.

Procedure:Upper esophageal sphincter myotomyUpper esophageal sphincter release operation to allow better swallowing. The intervention is done under GA and by extra-mucosal approach.

Study Arms

Research studies and clinical trials typically have two or more research arms. An arm is a group of people who receive the same treatment in the study.

Mild dysphagia

Severe dysphagia
