[Gastric Crohn's disease as a cause of gastrointestinal bleeding after gastroscopy--diagnostic difficulties].

Crohn's disease is a chronic, idiopathic inflammatory bowel disease localized most commonly in the terminal ileum, but it may involve any site of the gastrointestinal tract. Stomach location is extremely rare. Usually this process is confused by the presence of fistulas and intraabdominal abscesses in the typical emplacement, which are the consequences of penetration of the inflammatory process through the whole thickness of the large intestine's wall. In the case of ithe upper part of the gastro-intestinal tract location (commonly distal part of stomach or proximal of duodenum) bleeding is the most dangerous complication. In the diagnostics of this disease the combination of endoscopy and immunobiochemical tests of taking fragments has the basic importance. Pharmacological immunosupression with protection of the stomach mucosa is still the treatment's method of choice. We report the case of isolated gastroduodenal Crohn's disease of the stomach complicated with bleeding.
