The inability to burp (Retrograde Cricopharyngeal Dysfunction, R-CPD) is a dysfunction of the upper esophageal sphincter. The patient has often had the condition for an extended period of time, sometimes even since childhood.
The underlying cause of the inability to burp remains unclear.
The inability to burp is typically accompanied with a feeling of pressure behind the sternum, gurgling sounds in the throat and flatulence. Consuming many types of food, especially carbonated drinks, causes discomfort.
Treatment of the inability to burp
The inability to burp can be treated with a Botox injection.
The injection typically uses 100 units of botulinum toxin type A. The procedure is performed under general anaesthesia. After the procedure, the patient is discharged on the same day.
An oesophagoscopy or other examinations may be performed in connection with or prior to the procedure.
Results of the treatment
The objective is to restore the ability to burp normally and achieve the disappearance or substantial alleviation of symptoms.
A large proportion of patients experience permanent results after the procedure, with less than 10% of patients needing another injection.
