[Endoscopy in the diagnosis of chronic hepatitis C--diagnosis and therapy depending on the phase of diseases progression and liver regeneration].
The GI endoscopy can be divided into upper GI tract endoscopy (esophago-, gastro-, entero-, fistulo- and cholangioscopy) and lower GI tract endoscopy (recto-, sigmoido-, colonoscopy) from practical point of view and the characteristic of used equipment. A lot of therapeutic methods for GI tract is associated with each of these procedures. GI tract endoscopy doesn't play significant part in diagnosis of acute and chronic C hepatitis. Significance of endoscopy procedures decidedly increases in the case of progressive liver fibrosis and liver cirrhosis associated with HCV infection., where changes in GI tract are observed to 87% patients. These changes can be divided into: 1) not associated with portal hypertension, 2) these ones caused by portal hypertension. The most observed changes not associated with portal hypertension involve: reflux esophagitis, esophageal candidiasis; different variants of gastritis, gastric and duodenal ulcer. To the changes connected with portal hypertension, which are possible for endoscopy assessment, belongs esophageal and gastric varices, portal gastro-, entero-, colopathy, and gastric antral vascular ectasiae (GAVE). However to-day endoscopy has got not only diagnostic significance but also enables: estimation of pharmacotherapy efficiency, the primary and secondary prophylaxis of bleedings from GI varices as well as therapy of GI bleeding in this group of patients.
