[Algorithm for diagnosis of small intestinal diseases].
OBJECTIVE
To review diagnostic approaches in chronic diseases of the small intestine.


METHODS
A total of 1096 patients with chronic diseases of the small intestine were admitted to the clinic of the Central Research Institute of Gastroenterological Diseases in 1987-2006.


RESULTS
Most of the patients (90.5%) had celiac disease, hypolactasia and other types of disaccharidase deficiency, yersiniosis ileitis, Krohn's disease, postresection syndrome of a short small intestine, mesenterial ischemia and endocrine enteropathy. Rare diseases (general variable hypogammaglobulinemia, lymphoma, Wipple's disease and diverticulosis of the small intestine) were diagnosed in 5.8% cases. Primary amyloidosis of the small intestine, eosinophilic gastroenteritis, arteriomesenterial obstruction, primary intestinal pseudoobstruction, hypogammaglobulinemic spru, primary intestinal lymphangiectasia, tuberculosis, total polyposis, Peutz-Eggers and Cronkhite-Canada syndromes, collagenic sprue, erosive-ulcerative jejunoileitis, adenocarcinoma and heavy alpha-chain disease were detected in 3.7% examinees. These diseases were encountered in one to 5 cases for the latest 20 years.


CONCLUSIONS
Clinical diagnosis of small intestinal diseases is based on the syndromes of chronic diarrhea, defective absorption, enteral protein loss, small intestinal obstruction and intestinal hemorrhage. Differential diagnosis of the nosological entities employs x-ray, endoscopic, histological, immunological and other methods. Most of the small intestinal diseases including rare can be diagnosed in any gastroentorological department.
