What inspections should gastric carcinoma be done?
(1) X-ray examination of intestines and stomach Main inspection method of gastric carcinoma, including different to full of to throw, take the picture by revealing the mucomembranous line degree, throw it according to the double method of comparing of strength with etc. such as pressurizing, especially the barium pharmaceutical, air compare doubly with the method, it is very valuable as to the coat of the stomach small pathological change of detection.
1.The X-ray of the early gastric carcinoma behaves under pressurizing appropriately or comparing doubly with, the rising type often reveals the small one is full of defect, there are many not only whole surfaces, the base is slightly wide, the nearby mucous membrane is increased thickly, disorderlily, can distinguish with the benign polyp.
(2) The inner mirror is checked Can observe every position in the stomach directly, to gastric carcinoma, especially the diagnosis value to the early gastric carcinoma is very great.
1.The early gastric carcinoma rising type is mainly shown as some mucous membrane rises, dashes for ward it to the stomach, there is base of a fruit or wide base, the surface is coarse, some take the form of the papilla or tubercle, the surface can be rotten. The table is shown as simply type it is not neat in the border, some mucous membrane not obvious of demarcation line is coarse, the dislocated upwarping or sunken slightly, surface color turns light or ruddy, can be rotten, this kind of pathological change is aptest to omit. Getting sunken to it has to be comparatively obvious ulcer, sunken to exceed more mucomembranous floor. The above-mentioned various can amalgamate and have but form early gastric carcinoma of the phenotype.
2.Gastric carcinoma often has gastric carcinoma models that behaves in later period in China, the inner mirror is diagnosed to be easy. Pathological change of the rising type is relatively great in diameter, shape abnormality, take the form of cauliflower or chrysanthemum.
(3) The gastric juice is checked About half the a gastric carcinoma patient's achlorhydria. Lactic acid content can exceed normal (100 g/ml)s in the basic gastric acid . But the gastric juice is analyzed the diagnosis meaning in gastric carcinoma is not big.
(4) Biology and biological chemical examination Including immunology of cancer reacts, determination and enzyme of special chemical composition react etc. in one. Peptic and original peptic and original blood such as serum ratio of 2; Detection of embryo antigen of cancer and monoclonal antibody such as CEA, CA19-9, CA125,etc., but these are checked falsely and positively and falsely and negatively and relatively high, the specificity is not strong.
