Diseases of the gastrointestinal tract (gastroenterology)

Acute esophagitis

Acute esophagitis is divided into inflammations of infectious and inflammations of traumatic nature, the former - into non-specific and specific, the latter - into chemical burns and mechanical-traumatic injuries (perforations, ruptures, gunshot wounds).

Diphtheria esophagitis

Esophageal damage by diphtheria infection is a rare disease. It can occur in severe cases of pharyngeal diphtheria with spread to the hypopharynx and esophagus.

Herpetic esophagitis

Esophageal lesions caused by herpes simplex or shingles viruses are rare and usually occur with simultaneous lesions of various areas of the skin and mucous membranes.

Chronic nonspecific esophagitis

Chronic esophagitis, as a rule, develops from acute esophagitis and is practically based on the same etiological factors. They can be characterized by the formation of non-healing ulcers, the occurrence of long-term inflammatory processes with its cicatricial stenosis, tumors. Chronic esophagitis can be both non-specific and specific (tuberculosis, syphilis, actinomycosis).

Esophageal tuberculosis

Tuberculosis of the esophagus occurs extremely rarely, since the rapid passage of infected sputum does not contribute to the fixation of the pathogen in the mucous membrane; in addition, the mucous membrane of the esophagus is poor in lymphatic vessels, which also does not contribute to infection of the latter.

Esophageal syphilis

Syphilis of the esophagus is a disease that is not so common, occurring in all stages of this venereal disease, but most often manifesting itself in the tertiary period.

Esophageal foreign bodies

Ingestion of foreign bodies is a major hazard, especially in early childhood, due to the risk of developing severe, life-threatening complications and the difficulty in removing these foreign bodies.

Trichostrongyloidosis: causes, symptoms, diagnosis, treatment

Trichostrongyloidiasis is a zoonosis-geohelminthiasis. Humans are optional hosts. Adult helminths are localized in the small intestine of humans.

Hepatitis G

Viral hepatitis G is a viral infection with a parenteral transmission mechanism, occurring in an asymptomatic form.

Cancer of the head of the pancreas.

Periampullary cancer - cancer of the head of the pancreas often develops. It can originate from the head of the gland itself (more often from the epithelium of the ducts than from the cells of the acini), from the epithelium of the distal parts of the common bile duct, from the ampulla of Vater and the papilla of Vater, and less often from the mucous membrane of the duodenum.
