[Intestinal autograft: creation of an isolated intestinal segment by entero-enteropexy]

An isolated bowell segment (IBS) was created in rats by a two-stage procedure. Initial lateral entero-enteropexy between small and colonic bowell was performed. Six weeks later, the small bowell mesentery was divided. After four weeks, the survival animals were killed, the viability of the segment is maintained by developing vascular collateral across the coaptation between both intestinal segments, under light microscopy the willi were atrophied on 50% of animals.
