Endoscopic gastric cancer 1. Benign
Relatively rare benign tumor of the stomach, part of the tumor and the muscular layer starting from the subserosa, or highlight in the stomach outside or confined to the stomach, the endoscope can not see. Playing a more important clinically benign, self-adhesive film, and since both broke into the stomach submucosa. The endoscopic findings of submucosal tumors, including mostly spherical or semi-shaped uplift, base wide, flat, smooth surface, soft, color, normal, or bleeding ulcer rare. Great variation in size of tumor. Large diameter of up to several cm; gastric polyp is solitary or multiple occurrence of gastric tumor-like bulge, a good site is the gastric antrum, followed by the upper gastric body, the endoscopic findings of gastric polyps are circumscribed individual tumors were round or lobulated hemispherical, papillary or grass-like, smooth surface mucosa, mostly orange-red or dark red, can be pedunculated or broad based, long-pedicle polyps top of the more obvious changes, sometimes acetabular moss, redness or bleeding, rarely bad health. If the polyp surface and necrosis of superficial William Black, polyps are infiltrated base changes, the surface particle size range; alignment is uneven coverage of cellulose and so on, to be alert to polyps loyalty, the possibility of change.
Stomach cancer endoscopy 2. Malignant lung cancer
Gastric cancer: endoscopic diagnosis of gastric cancer is significant. Can be found in gastric cancer, and malignant ulcer were identified, to determine the type of gastric cancer and lesions infiltrating the scope of clinical treatment.
A. Early gastric cancer
According to the Japanese Endoscopy Society in 1962 proposed in the early endoscopy is defined as: cancer limited to mucosa Lian Run or submucosa, with or without lymph node metastasis. This classification method is only emphasized the depth of invasion. Seen under the form of eye disease, the Japanese Endoscopy Society will be divided into the processes of early gastric cancer type (I type), superficial type (II type) and depressed (field type) in three basic types. Endoscopic features, including the following :
I type early gastric cancer: cancer was significantly elevated, its height is equivalent to more than 2 times the thickness of gastric mucosa (the equivalent of more than 5mm), showed a polyp-like protrusions, the surface uneven, with white cover, the color red or pale with bleeding spots , mucosal erosion, and some pedunculated, some sessile and broad-based, the latter more common. Pedunculated polypoid lesion, diameter less than 2cm, is unlikely to be early gastric cancer; broad-based polypoid lesions, irrespective of size, should be suspected early gastric cancer.
H-type early gastric cancer: This type is divided into three subtypes: ITa type early gastric cancer: its uplift height of not more than 2 times the thickness of gastric mucosa, the tumor showed a platform-like bulge from the mucous layer, the larger, surface irregularities, uneven , or a central depression, IIc lesions can be combined, there is bleeding, erosion or coating adhesion, color may be pale or red. The surrounding mucosa may also have bleeding and erosion, this type of eye disease diagnosis is more difficult to rely on the biopsy and cytology.
IIb-type early gastric cancer: tumor neither bulge nor sag, no more than mucosal surface, no boundaries with the surrounding mucosa, the main change is more extensive pale mucous membranes such as redness or discoloration, regional mucosa is not sharp, not flat, irregular and so on.
IIc type early gastric cancer: diagnosis of this type more easily, pale mucous membrane lesions concave or erosion, the bottom covered with moss or unusual from the red, showed granular changes locally, irregular edges or insect bite-like lesions, wrinkle Male Main sudden interruption or ladder-like changes. Concentrated to the center may have wrinkled skirts, these wrinkles can be suddenly interrupted garnet, cutting-edge thinning, or changes or breast enlargement together, sometimes in depressions or irregular-shaped islands can be left non-cancerous mucosa.
Type III early gastric cancer: cancer showed a depression or ulcer appears, like chronic benign ulcer, the base often necrotic exudate covered, jagged, bleeding, erosion, and nodular mucosa does not uplift the surrounding or slightly elevated, such as large ulcer was cured of multiple once again, we should consider this type of cancer.
There are also some special type of early gastric cancer, such as small early gastric cancer, small stomach, mixed in early gastric cancer and gastric cancer spots in the endoscopic diagnosis, the lesion is small, easily missed, it should be carefully observed, more than biopsy, in order to avoid misdiagnosis .
