[Small intestine perfusion. The authors' own method for the simultaneous performance of biopsy and perfusion of the human small intestine].

The analysis of advantages and disadvantages of the technique and principles of the methods of small intestinal perfusion, used by various authors in the studies on resorption processes, provided grounds the authors to develop their own method. The system for infusion and aspiration by a combined probe is described. Details about the composition of perfusion solution, the technique of the study and calculation of resorption rate are reported. The advantages of the method are as follows: simultaneous performance of small intestinal glucose perfusion and biopsy of small intestine, good tolerance by the patients and availability of the elements needed for the construction of the probe and system for infusion and aspiration. The mean glucose resorption rate was 814,07 mumol/min/30 cm in 9 subjects with no small intestinal diseases and with normal histomorphological picture of small intestinal mucosa.
