Patient: Description of the disease (onset time, main symptoms, hospital, etc.): the patient is female, the disease for 5 years, the main symptom is difficult to swallow meals, when serious even water can not swallow, people obviously thin, often vomit after eating, and night reflux cough, gastroscopy, barium meal confirmed the diagnosis of pancreatic flaccid disease. I had two injections of botulinum toxin, which had an effect, but the condition remained the same for a period of time, and I had three balloon dilatation in Gansu Provincial People’s Hospital, which was also effective, but the effect was not long. Want to treat completely. Doctor: Hello, pancreatic dystonia can be treated surgically if repeated dilation and botulinum toxin injections are ineffective. Patient: Thank you, doctor, I saw a therapy called “endoscopic placement of relaxing dilators”, is this therapy the same thing as putting a stent in, which is better than surgical treatment Doctor: surgical effect is better and more durable.
