There are no definitive data on the survival of inability to eat in pancreatic dysphagia. Pancreatic achalasia is characterized by intermittent dysphagia, retrosternal heaviness or obstruction, and usually has a long duration of illness. If you can’t eat, it means that the symptoms are more severe or may be in the middle or late stage and develop into esophageal cancer. The average survival time after diagnosis of esophageal cancer is 12.7 months, and the five-year survival rate is about 4.54%. If pancreatic achalasia is detected when the disease process is in an early state, it can be treated by changing dietary habits, such as eating small meals, chewing slowly, avoiding too cold or too hot food, and esophageal dilatation, which may not affect eating and life expectancy. Therefore, it is recommended to treat the disease as early as possible, prevent it at an early stage and review it regularly.
