Participation of the colon in the compensatory process after massive intestinal resection. An experimental study in rats

The colon participation in the adaptation process after massive intestinal resection (R.I.M.) has been rarely studied. This is an experimental study in rats to know the morphological modifications to the colon after R.I.M. of small bowel. A total of 90 Wistar rats weighing 200-250 grams were used, in two groups. Twenty animals constituted group I (control) and 70 were submitted to resection of 85-90 per 100 of the small bowel (group II, R.I.M.). Radiologic and weights controls has been performed. To end of study (four months),a the animals were sacrificed to obtain histologic samples of the large bowel for structural and morphometric studies. The results of this study to confirm the colon participation in the compensatory adaptation process after R.I.M. of small bowel.
