Increased permeability of the gastrointestinal mucosa
Introduction
Introduction Increased permeability of gastrointestinal mucosa: more common in gastric cancer and colon cancer due to necrosis of cancer tissue caused by increased permeability of the corresponding gastrointestinal mucosa, a large amount of plasma protein leaked from the gastrointestinal tract.
Cause
Cause
The cause of increased permeability of the gastrointestinal mucosa is mostly caused by gastric cancer and colon cancer.

Diagnosis of increased permeability of the gastrointestinal mucosa: A protein-deprived gastrointestinal disorder can be confirmed by a radionuclide-labeled macromolecular substance digestive tract excretion test, or an 1-antitrypsin test.
Diagnosis
Differential diagnosis
Differential diagnosis of increased permeability of the gastrointestinal mucosa:
First, protein loss gastrointestinal disease
More common in gastric cancer and colon cancer, due to the necrosis of cancer tissue, the permeability of the corresponding gastrointestinal mucosa is increased, and a large amount of plasma protein is lost from the gastrointestinal tract. Carcinoma compresses and blocks lymphatic vessels, causing obstruction of gastrointestinal lymphatic drainage, lymphatic deposition, rupture, and loss of large amounts of protein. Clinically, hypoproteinemia and edema are the main manifestations.
Second, small intestine villi atrophy
Can be seen in colon cancer, rectal cancer, mainly manifested as diarrhea.
Third, diarrhea, dehydration and shock
Mainly found in colonic villus adenomas, occasionally in the digestive tract APUD system tumors, such as VIP tumors, gastrinoma and pancreatic polypeptide tumors. It is characterized by secretory diarrhea, which can lead to loss of water, electrolyte imbalance, and even shock.
A protein-deprived gastrointestinal disorder can be confirmed by a radionuclide-labeled macromolecular substance digestive tract excretion test, or an 1-antitrypsin test.
