title: [Morphological assessment of the adaptation process in the small intestine after jejunoileostomy for extreme obesity].
abstract: The paper presents the author's experiments performed for examining the morphological adaptation in the intestinal loop, preserved for the food passage after jejunoileostomy for extreme obesity. Macro-, micro-, and ultramicroscopic examinations were carried out in 20 patients. A characteristic elongation and hypertrophy of the active intestinal loop, thickening of its wall (especially mucosa), hypertrophy and elongation of the intestinal villi as well as reduction of the mucous cells could be observed. The enzymatic activity of the mucous membrane could be found to be increased in the active part of the jejunum too. In the author's opinion the observed changes clearly demonstrate the transient character of those metabolic disturbances which develop after producing the artificial short gut syndrome.
