The causes of sore throat caused by pancreatic resection are usually sphincter function loss, esophagitis, upper respiratory tract infection and other reasons. 1. Loss of sphincter function: the loss of sphincter function after cardia resection will lead to the backward flow of stomach acid into the esophagus, and even into the throat area, resulting in burning pain. 2. Esophagitis: Esophagitis will lead to abnormalities in the digestive system, mainly heartburn, abdominal discomfort and other symptoms, and in severe cases, it will lead to sore throat, hoarseness and other symptoms. 3. Upper respiratory tract infection: patients’ resistance is poor after cardia resection, and they are prone to produce phlegm and prone to respiratory tract infection when they are bedridden after surgery and left with gastric tube, and upper respiratory tract infection will have sore throat. It is recommended that patients go to the hospital in time for examination, symptomatic treatment under the guidance of the doctor, and insist on regular postoperative review.
