The term “major surgery” generally refers to surgeries with greater surgical risk and difficulty. Gastrectomy surgery may have greater surgical risk and difficulty depending on the type of surgery, e.g. radical resection for gastric cancer has greater surgical risk and difficulty.
Clinically, if gastric ulcer or duodenal ulcer occurs, or benign tumor occurs in the stomach, when there are surgical indications for surgery, it is feasible to have partial gastrectomy, which is a benign disease, the scope of the surgery is relatively small, and does not belong to the major surgery, which generally belongs to the medium risk and difficulty of the surgery.
If malignant tumors occur in the stomach, such as gastric cancer, if there is no distant metastasis and the patient can tolerate surgery, surgery is feasible and radical gastrectomy for gastric cancer is needed, which not only needs to resect the stomach, but also needs to remove the lymph nodes, so the surgical risk and difficulty are relatively high.
After the lesions occur in the stomach, it is necessary to improve the examination to be able to judge the type of lesions, and then appropriate treatment can be chosen.
