    Abstract:
    The present study was performed in male Wistar rats. They underwent a 75% removal of the middle part of the small intestine and various procedures to delay the passage time in order to manage short bowel syndrome. Comparisons were made between the following groups: animals with subtotal resection of the small intestine and counterpositioning of a segment of the small intestine, myotomy, isoperistaltic segment, and animals with removal of the small intestine without delayed passage time, and a group of healthy non-operated controls. One year after surgery the following examinations were carried out: gross measurement of length and width of the intestine, eye microscopy, calculations of the intestinal surface, and morphometric investigations in histologic specimens of the intestinal mucosa. The most extensive increase of the residual lumen was observed in animals with antiperistaltic segment interposition. The inhibition of the passage due to the antiperistaltic segment has remained effective during the entire test period despite extreme loading and despite the morphological changes described in the article.
