[Changes in the motility of the small intestine after autologous and allogenic transplantation in the dog].

The early and the late motility of the donor organ was measured after 13 allogeneic and 4 autologous small bowel transplantations in mongrel dogs. The postoperative motility indices were increased in contrast to the preoperative values. The activity of allogeneic transplants were greater than these of autologous intestinal segments. The basal tonus of the intestinum obtains a higher level because inhibiting central nervous influences are omitted after the denervation of the mesenteric radix. The contraction frequency remained constant. Disturbances of the motility model with irregular contractions and decrease of the frequency become evident in case of ischemia and rejection of the transplant still before the clinical signs.
