Stiff stomach wall
Introduction
Introduction Invasive gastric cancer: localized manifestations of abnormal thickening or disappearance of mucosal stenosis, localized gastric wall stiffness, narrow gastric cavity fixation, filming at different locations in the same position, double shadows on the stomach wall, indicating normal peristaltic stomach wall and stiff stomach wall contour Heavy. The widely infiltrated mucosal folds are flat or disappear, the gastric cavity is significantly reduced, the entire stomach wall is stiff, and no peristaltic waves are visible.

Causes of stiffness of the stomach wall: The extensive infiltrating mucosal folds are flat or disappear, the gastric cavity is significantly reduced, the entire stomach wall is stiff, and no peristaltic waves are visible.

Examination and diagnosis of stiffness of the stomach wall:
(1) Gastrointestinal X-ray examination: It is the main examination method for gastric cancer, including the projection of different filling degrees to display mucous membrane lines, such as double contrast of pressurized projection power, especially the double contrast method of tincture and air. It is valuable to detect small lesions in the stomach wall.
(B) endoscopy: can directly observe the various parts of the stomach, the diagnosis of gastric cancer, especially for early gastric cancer is of great value.
(C) gastric juice examination: about half of gastric cancer patients with gastric acid deficiency. The lactic acid content of the basic gastric acid can exceed the normal (100 g/ml). However, gastric juice analysis has little significance in the diagnosis of gastric cancer.
(4) Biological and biochemical examinations: including immunological reactions of cancer, determination of specific chemical components in the body, and enzymatic reactions. Blood such as serum pepsinogen I and pepsinogen I / II ratio; CEA, CA19-9, CA125 and other carcinoembryonic antigen and monoclonal antibody detection, but these tests have higher false positives and false negatives, specificity Not strong.
Diagnosis
Differential diagnosis
Differential diagnosis of gastric wall stiffness:
Muscle wall muscle defect: most of the muscle wall defects of the stomach wall are congenital gastric wall muscle defects, congenital defects of gastric muscle defects (congenital defects of gastric musculature) refers to the muscular wall defects caused by embryonic developmental disorders. Congenital gastric wall muscle defects are rare in clinical practice and are the most common cause of spontaneous gastric perforation in neonates. The mortality rate is extremely high, and it is still 35% to 72%.
Gastric mucosal damage: The entire inner surface of the stomach is covered with a layer of mucosal tissue that secretes mucus, forming a mucous-mucosal barrier of the stomach to protect the stomach tissue. Gastric mucosal injury is more common in gastritis and gastric ulcer.
