Summary

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.

Conditions

  • Cricopharyngeal Achalasia

Interventions

DRUG

Injectable Type A Botulinum Toxin

Injectable Type A Botulinum Toxin (National Medical Products Administration Approval Number S10970037) 100 unit, diluted with 1ml of 0.9% sodium chloride solution for injection and kept ready for use. Only once. Using an ultrasound probe to scan the neck, the position of the lowest point, highest point, and lower middle point of the esophageal high-pressure zone are determined, and marks are made on the body surface and catheter wall. The high-pressure point and the lower middle point are selected as injection sites on the left side. The above area is locally disinfected, and the probe is covered with a sterile cover and coated with sterile coupling agent. Using a plane approach, 0.3ml or 30 unit of botulinum toxin is injected separately after reaching the esophageal circular layer at each of the two left injection points. A total of 60 unit of botulinum toxin is injected at the two left points.
