Trial summary

cricopharyngeal achalasia refers to incomplete or non-open functional opening of the cricopharyngeal muscle, and after repeated swallowing of food, it still cannot pass through the cricopharyngeal muscle, remaining in the epiglottic valley and the piriform fossa, and even regurgitated into the nasal cavity .

About this study

cricopharyngeal achalasia refers to incomplete or non-open functional opening of the cricopharyngeal muscle, and after repeated swallowing of food, it still cannot pass through the cricopharyngeal muscle, remaining in the epiglottic valley and the piriform fossa, and even regurgitated into the nasal cavity . Neurogenic diseases, myogenic diseases and head and neck tumors are the common causes. Patients with chronic underfeeding lead to malnutrition, reduced quality of life, affecting the outcome of the disease. At present, the treatment measures for cricopharyngeal achalasia at home and abroad include balloon dilation technique, surgical incision, botulinum toxin injection. The dilation of the balloon is easy to cause mucosal edema and damage. Local infection, massive hemorrhage, local nerve injury and other complications often occur in cricopharyngotomy. Botulinum toxin injection relieves muscle spasms and is now widely used to treat dystonia. Common injection localization methods include CT, ultrasound, electromyography and endoscopy. Ultrasound-guided injection is a new technique of visualization, simple and non-radiation injection guidance, which can observe the injection process and drug injection position in real time. Fixation with a balloon can further improve the accuracy of the injection. In this study, botulinum toxin was injected into the cricopharyngeal muscle by ultrasound combined with balloon.

Read the detailed description

Under the ultrasound combined with balloon fixation, two injection sites were selected from the left upper esophageal sphincter, and 30U was injected respectively, and one injection site was selected from the right side, and 30U was injected. In addition, the patient also received routine swallowing training once a day for 30 minutes.

What is being measured

The primary outcome is the main question the study is designed to answer.

  1. Functional Oral Intake Scale

    According to whether the patient can eat by mouth and the degree of dependence on nasal feeding tube, it is divided into 7 grades, corresponding to 1-7 points respectively. The higher the score, the better the swallowing function.

    Measured: pre-treatment、2 weeks after treatment、4 weeks after treatment、24 weeks after treatment

  2. Rosenbek penetration-aspiration scale

    Based on the results of Videofluroscopic swallowing study (VFSS), the cases of leakage and aspiration were divided into 8 grades, corresponding to 1-8 points respectively. The higher the score, the better the swallowing function.

    Measured: pre-treatment、2 weeks after treatment、4 weeks after treatment、24 weeks after treatment

Secondary outcomes (3)
  1. Murray secretion scale

    Based on Fiberoptic endoscopic evaluation of swallowing (FEES), the accumulation position of oropharyngeal secretions was described and divided into 4 grades. The higher the score, the worse the swallowing function.

    Measured: pre-treatment、2 weeks after treatment

  2. yale pharyngeal residue severity rating scale

    Based on Fiberoptic endoscopic evaluation of swallowing (FEES), the main indicators include the location of the residue (epiglottic valley and pyriform sinus) and the amount of residue, which is divided into 5 grades. The higher the score, the worse the swallowing function.

    Measured: pre-treatment、2 weeks after treatment

  3. fiberoptic endoscopic dysphagia severity scale

    Based on Fiberoptic endoscopic evaluation of swallowing (FEES), Eat different foods and observe whether penetration aspiration and protective reflex occur. The highest score is 6, which means that saliva accumulates with penetration or aspiration, and the lowest score is 1. When eating soft solid food, there is no leakage or aspiration, and there is little or moderate residue in epiglottic valley or pyriform sinus. The higher the score, the worse the swallowing function.

    Measured: pre-treatment、2 weeks after treatment

Questions about this trial

What is this clinical trial studying?

A study testing Botulinum toxin type A for injection in people with Cricopharyngeal Achalasia and Dysphagia, run by The First Affiliated Hospital of Zhengzhou University at 1 site in China.

The full registered description is in the About this study section and the official record.

Who may be eligible to take part?

The sponsor lists 5 inclusion and 6 exclusion criteria. Eligibility is decided by the study team after screening, so read the full criteria and contact a listed site.

Is this clinical trial currently recruiting?

The record says: status not confirmed, as of the sponsor's last update on 16 May 2024. Status can change between updates, so confirm with the study contact before making plans.

Where is the study taking place?

The record lists 1 site in China. Whether a site is taking part right now should be confirmed with that site. See every site.

What are the possible benefits and risks?

They depend on the study and the treatment, and no study can promise a benefit. The study team explains the known risks during informed consent, before anyone joins; the record itself does not list them.

Are results available for this study?

How can a doctor refer a patient or contact the research team?

Contact Yuli Zhu (+8615351370521, 15351370521@163.com), or a site near the patient. AzTrials does not enrol participants or take referrals.

What does the primary outcome measure?

Functional Oral Intake Scale (time frame: pre-treatment、2 weeks after treatment、4 weeks after treatment、24 weeks after treatment). The study lists 2 primary outcomes in all. It is what the study was designed to measure, not a finding.

Where can I read the original study information?
Does a listing mean the treatment is approved or proven to work?

No. A listing means the study is registered. It does not show that the treatment is safe, works, or is approved by a regulator.

How often is this information updated?

AzTrials copies changed records from ClinicalTrials.gov every night and reloads the whole registry every week. The sponsor last updated this record on 16 May 2024.
