Most gastric ulcers do not require surgery if they are superficial and incipient ulcers. When surgery is needed, there are several aspects: 1. Gastrointestinal bleeding from ulcers. Gastric ulcers are prone to upper gastrointestinal bleeding, especially hemorrhagic shock and gastrointestinal hemorrhage, which are difficult to cure by giving conservative treatment and require surgery. 2. Pyloric obstruction. The recurrence of ulcer disease, prone to pyloric stenosis, followed by obstruction, repeated obstruction is not relieved, conservative treatment is not relieved, also need surgical treatment. 3, perforation of the digestive tract. The repeated ulcers are not relieved for a long time, which may lead to perforation of the peptic tract, that is, the ulcer has reached the intrinsic muscular layer and penetrated into the plasma membrane layer leading to perforation of the peptic tract, which is prone to spontaneous peritonitis, infectious shock, and even sepsis, requiring urgent surgical treatment. 4. malignant transformation of gastric ulcer. A small number of ulcers are prone to malignancy, and if malignancy occurs, surgical treatment is required, and radiotherapy and chemotherapy are given after surgery to further treat the malignant condition of ulcer disease.
