Gastric fungal disease

Introduction to gastric mycosis Fungi are extremely widespread, and there are often numerous fungi in air, water, and food, and they are often found in human mouth, stomach, and intestines. Usually it is only a harmless parasitic, but it can cause gastritis or ulcers, even perforation and sinus formation when the blood circulation disorder or immunity of the gastric mucosa is reduced. In the early stage, a layer of diphtheria-like pseudomembrane is often formed on the gastric mucosa, and then it can develop into an ulcer. Sometimes an embolization of the submucosal blood vessels may occur. The ulcer formed may be single or large, sometimes involving the entire stomach wall, and generally does not form a perforation. basic knowledge The proportion of the disease: the incidence rate is about 0.001% -0.002%, more common in low constitution or oral candida infection Susceptible people: no special people Mode of infection: non-infectious Complications: gastric bleeding, peritonitis, sepsis

Etiology of gastric mycosis

Fungal infection (35%):

The main species that can cause gastric mycosis are monilia albicans and aspergillus, while actinomycetes are rare. According to Bearse (1936), local blood circulation disorder or immunity of gastric mucosa Decreased may be the basis for the occurrence of fungal diseases.

Pathogenesis (25%):

At the beginning, a layer of diphtheria-like pseudomembrane is often formed on the gastric mucosa, and then it develops into an ulcer. Sometimes, embolization of the submucosal blood vessels may occur. The ulcer may be singular or majority, sometimes small, and sometimes may affect the entire stomach wall, but generally No perforation is formed, and fungi are often found in necrotic tissue on the lesion. Sulfur granules are seen in the case of actinomycetes infection.

Usually improper diet (20%):

Usually eating improperly in life, unclean can also cause the disease.

Gastric mycosis prevention

1, eat less fried food: because this type of food is not easy to digest, will increase the burden of the digestive tract, eat more will cause indigestion, but also increase blood lipids, which is not good for health.

2, eat less pickled food: these foods contain more salt and some carcinogens, should not eat more.

3, eat cold food irritating food: cold and irritating food has a strong stimulating effect on the digestive tract mucosa, easily lead to diarrhea or digestive tract inflammation.

Gastric mycosis complications Complications, gastric bleeding, peritonitis, sepsis

Stomach hemorrhage: hemorrhage after rupture of blood vessels, leading to hematemesis and melena, generally increased pain before hemorrhage, pain relief after hemorrhage, a large amount of blood in the stool, a large amount of bleeding in the digestive tract in a short period of time, accompanied by rapid pulse, lower blood pressure and lower hemoglobin value. Need a blood transfusion treatment.

Gastric and duodenal perforation ulcers develop to a deeper layer, penetrate the serosa layer and communicate with the abdominal cavity, so that the contents of the stomach and duodenum are flown into the abdominal cavity, and acute peritonitis occurs, which is called acute perforation L. It is common in the duodenal anterior wall ulcer perforation, which is a serious complication, and the patient can die from peritonitis and sepsis.

Gastric mycosis symptoms common symptoms

The clinical manifestations are non-specific and can be difficult to distinguish like gastritis, gastric ulcer or cancer. X-ray examination can not help the diagnosis. Although a large number of fungi can often be found in vomit and stomach contents, due to gastric mycosis It is so rare, and there may be many chances of finding fungi in the stomach contents. Therefore, it is not considered that the fungus is considered to be a gastric fungal disease. All the reported gastric fungal diseases in the literature have failed to have a correct clinical diagnosis, and the final diagnosis is only Can rely on surgery or biopsy.

Examination of gastric mycosis

Histopathological examination is the basis for the diagnosis of this disease. The presence of a pseudomembrane is observed in the section, and hyphae can be found under the microscope.

Diagnosis and identification of gastric mycosis

The clinical manifestations are non-specific. The disease should be considered after the exclusion of gastritis, gastric ulcer or cancer. The biopsy can confirm the diagnosis.

The disease needs to be differentiated from gastritis, gastric ulcer and gastric cancer.
