The success rate of stomach cancer surgery mentioned by patients needs to be answered in many aspects, because most stomach cancers need surgical treatment, and the purpose of surgery is to remove the lesions and rebuild the digestive tract. The process of removing the lesion is closely related to the degree of development of the lesion, because many gastric cancer patients are found in advanced stage, and the lesion has obvious adhesion with surrounding organs and tissues, in which case the success rate of surgical resection is bound to decrease. When reconstructing the digestive tract, it is also directly related to the state of the patient’s abdominal cavity. Generally speaking, the success rate of gastric cancer surgery is still relatively high, which is more than 70%, and some of the patients with early gastric cancer can be operated endoscopically with a high success rate, which is generally more than 90%.
