Surgical treatment of stomach cancer
So far the treatment of stomach cancer, the effect is still not satisfied. This regard because of gastric cancer is unclear reasons, should not be in its prior to the onset of prevention; on the other hand, the time of diagnosis in most cases are already in advanced patients, efficacy of the natural poor. Therefore improve the early diagnosis of stomach cancer is still the key to treatment.

First, surgical treatment

For the treatment of stomach cancer is currently the main method is the only possible cure for a means of advanced gastric cancer.

(1) a variety of surgical options

1. Radical excision

Also known as curative resection. Stomach cancer is about the original lesions, together with some of these bodies and their corresponding regional lymph nodes be removed, no residue of any clinical cancer tissues. Also because of the scope of regional lymph node dissection are different, while divided into four different radical mastectomy: the first leg is not totally removed lymph nodes, said R. Operation: The first stop for the R1 to remove lymph node surgery, to remove all the same the second leg or the third leg of the lymphatic, called R2, or R3 operation, but also the extent of lymph node metastasis in accordance with the scope of the relationship between lymph node dissection, the distinction between absolute and relative radical for two kinds of radical, absolutely radical lymphadenectomy refers to the first stop beyond the metastatic lymph nodes above the first leg such as lymph node metastasis, the purposes of R2 or R3 radical, namely, that the absolute cure. Such as R1 only surgery, although clinically no residual metastatic lymph nodes, but only think is relatively radical.

General radical gastrectomy scope should include the original lesions, including proximal or distal stomach of the 2 / 3 ~ 3 / 4, full size omentum, and gastrocolic ligament hepatogastric and guitar mesenteric leaves, the first part of duodenum and stomach regional lymph node. Sometimes, in order to clear the body of stomach cardia cancer next door spleen, lymph nodes around the splenic artery, have to line the entire stomach and pancreatic body, tail and spleen together with the expansion of radical resection. Cancer involving the transverse colon or left lobe of liver and other adjacent organs, it can be used together with the involvement of radical organ resection United.

Radical mastectomy because of the expansion of surgical mortality and the incidence of postoperative complications in high and therefore should be strictly surgical indications, such as no choice will be to expand the implementation of gastric cancer are radical mastectomy does not improve the survival rate of gastric cancer. Body is generally believed that gastric cancer, diffuse infiltrating cancer and lymph node metastasis has been the second leg of the gastric antrum in principle should be extended radical operation.
