The suggested method of an experimental animal preparation for simultaneous study of the motor and secretory functions of the small intestine through the single fistula consists in transection of the intestine with its distal end tightly sutured, and the proximal one end-to-end anastomosed to the efferent loop 22-24 cm from the sutured end. Into the formed in such a way "blind" site of the intestine, a fistula is inserted, which divides it into the "secretory" (12 cm in length) and "communicant" (10 cm) segments. From the "secretory" one the pure intestinal juice is aspirated through the fistula by a catheter, and intestinal motility is registered by means of a pressure gauge brought through the "communicant" segment into the intestine.
