Endoscopic Yamada classification of polyps

Yamada Type

Yamada Type

Polyps are divided into 4 types: type I is the most common, the angle between the polyp and gastric mucosa is greater than 90°, and the color is similar to the surrounding mucosa or slightly red; type II polyps are sessile, and the angle between the polyp bulge and the gastric mucosa is nearly 90°; type III The surface of the polyp is irregular and sessile, and the angle between the polyp and the mucous membrane is less than 90°; the type IV polyp has a thin pedicle, the length of the pedicle is different, the surface is smooth, and it may be eroded or nearly granul.

Early gastric cancer classification

Early gastric cancer classification

Early gastric cancer tissue is limited to the mucosa and submucosa, regardless of whether there is lymph node metastasis, called early gastric canc.

Advanced gastric cancer classification (Bormann classification)

Advanced gastric cancer classification (Bormann classification)

Bormann's classification (1923) is the most widely used method for the classification of progressive gastric cancer in the wor.

Bormann's classification (1923) is the most widely used method for the classification of progressive gastric cancer in the wor.

Bormann type Ⅰ: Bormann type Ⅰ: (nodular or polypoid type) The cancer mainly protrudes into the stomach cavity and can be polypoid, mushroom-shaped or nodul.

Bormann type Ⅱ: Bormann type Ⅱ: (local ulcer type) There is obvious ulcer formation on the surface of the tumor, and the ulcer edge is obviously raised and bank-shap.

Bormann III: Bormann III: (Infiltrating Ulcer Type) There is also obvious ulceration on the surface of the tumor, but the edge of the ulcer is sloping, and the bottom of the ulcer grows infiltratingly to the deep and surrounding areas, making the tumor demarcation uncle.

Bormann type IV: (diffuse infiltrative type)

Bormann type IV: Bormann type IV: (diffuse infiltrative type)

peptic ulcer staging

peptic ulcer staging

Active stage (stage A): In this stage, there is thick fur on the ulcer surface, also known as "thick fur phas.

Phase A is divided into 2 distinct phas.

Active stage (A stage): Active stage (A stage): In this stage, the ulcer surface has thick fur, also known as "thick fur phas.

Phase A is divided into 2 distinct phas.

A1 stage ulcers have thick and dirty coating, the surrounding mucosa is hyperemic and swollen, and there is no wrinkle sequel;

A1 stage ulcers have thick and dirty coating, the surrounding mucosa is hyperemic and swollen, and there is no wrinkle sequel;

In stage A2, the moss on the ulcer surface is thick and clean, the swelling of the surrounding mucosa gradually disappears, and the healing period of the mucosal folds concentrated on the ulcer occurs (stage H): This period is also called "thin moss period" due to the thin mo.

H1 stage is characterized by shrinking ulcers, peripheral epithelial regeneration, formation of flushing, and mucosal folds concentrating on the ulcers;

H1 stage is characterized by shrinking ulcers, peripheral epithelial regeneration, formation of flushing, and mucosal folds concentrating on the ulcers;

The H2-stage ulcer shrank significantly and was close to heali.

Patients at this stage generally require maintenance thera.

Patients at this stage generally require maintenance thera.

Scar stage (S stage): In this stage, there is no moss, and scarring is form.

Scar stage (S stage): Scar stage (S stage): There is no moss in this stage, and a scar is form.

S1 stage is the red scar stage, the ulcer surface disappears, the central congestion is red, and the scar is r.

S1 stage is the red scar stage, the ulcer surface disappears, the central congestion is red, and the scar is r.

Stage S2 is a white scar stage, where there are shallow and small depressions in the mucosal folds, which are similar in color to normal mucous membran.

When entering this period, treatment can generally be stopp.

Note: If it is difficult to distinguish the faded spots in the center of the S1 stage from the small thin white fur in the H2 stage, it can be called the H3 sta.
