Still choking 3 months after cardia cancer surgery may be caused by anastomotic edema, anastomotic stenosis and recurrence of cancer. 1. Anastomotic edema: poor physical condition and malnutrition of postoperative patients can lead to anastomotic edema, which will be gradually relieved after nutrition enhancement and swelling reduction treatment. 2. Anastomotic stenosis: anastomotic stenosis can lead to choking feeling, if the anastomosis is narrowed, it needs to be expanded by swallowing food. If it does not improve for a long time, endoscopic anastomotic dilatation is needed to relieve the symptoms. 3. Recurrence of cancer: patients after cardia cancer surgery can also have recurrence of cancer. If there is recurrence of the disease, the patient may always choke on meals and the situation will be aggravated progressively. Patients who always choke on meals after cardia cancer surgery need to continue treatment. In life, diet should be rich in enough nutrition and do not eat dry and hard food. If the patient always chokes on his meal, he needs to go to the hospital in time.
