Cardia ulcer surgery does not necessarily require an open chest. There are options for cardia ulcer surgery such as gastroscopic mucosal dissection, open thoracic surgery and open abdominal surgery. Cardia ulcers can be caused by simple peptic ulcers or malignant disease of the cardia. If the cardia ulcer is caused by simple peptic ulcer, the main treatment is medication, acid-suppressing drugs such as omeprazole, gastrointestinal dynamics drugs such as domperidone, gastrointestinal mucosal protection agents such as aluminum thioglycollate and so on, and the use of medication should be in accordance with the doctor’s prescription. If the effect of drug treatment is not satisfactory, gastroscopic mucosal dissection is feasible. If the cardia ulcer is caused by malignant disease such as cardia cancer, according to the stage of tumor, the depth of infiltration of tumor cells is shallow in the pre-tumor stage, which can be treated by gastroscopic mucosal dissection. If the tumor is highly malignant and has metastasis around the cardia, surgical treatment is needed, and the surgery includes opening the chest to establish thoracic access and opening the abdomen to establish abdominal access, and the specific choice of surgery is decided according to the invasion and metastasis degree of the malignant tumor. It is recommended that patients with cardia ulcer should go to regular hospitals as soon as possible and listen to the advice of professional doctors.
