Cricopharyngeal Achalasia Clinical Trial
Official title:
The Impact of Ultrasound-guided Botulinum Toxin Injection on Cricopharyngeal Muscle Dysfunction Under Balloon Localization
Ultrasound-guided injection is a visual, convenient, and radiation-free technique that allows real-time observation of the needle insertion process and drug injection location. The combination with a balloon for fixation further enhances the precision of the injection. In this study, we employed ultrasound-guided injection combined with balloon localization for cricopharyngeal muscle botulinum toxin injection treatment and conducted clinical observations.
The patient's long-term inadequate food intake leads to malnutrition, decreased quality of life, and impacts the prognosis of the disease. Currently, both domestically and internationally, treatment options for cricopharyngeal muscle dysfunction include balloon dilation technique, surgical incision, and botulinum toxin injection. Passive dilation with a balloon can easily cause mucosal edema and damage. Cricopharyngeal myotomy surgery often presents complications such as local infection, excessive bleeding, and local nerve damage. Botulinum toxin can alleviate muscle spasms and has been widely used in the treatment of hypertonic disorders [3]. Common injection localization methods include ultrasound, electromyography, and endoscopy.
