A frequent choking sensation in the back is not excluded from esophageal pathology. Benign esophageal strictures, esophageal diverticula are common, and the gradual development of esophageal ulcers can also lead to malignant changes in the ulcers. The most common is atypical hyperplasia of squamous epithelium, which will eventually turn into squamous carcinoma as well. The occurrence of esophageal cancer has certain regional structural differences, especially in the relatively economically backward areas, where the diet structure is unreasonable, often eating pickles or drinking high concentration of alcohol, as well as eating food that is too hot will easily lead to the emergence of esophageal ulcers, and the patient will have obvious choking sensation when eating, and usually have post-sternal discomfort or back pain, and burning sensation, which can be clearly diagnosed by gastroscopy or upper digestive tract imaging. Gastroscopy or upper gastrointestinal imaging can make a clear diagnosis. For early diagnosis of esophageal malignant tumors, surgical treatment should be actively carried out, and advanced patients can also be treated by radiotherapy.
