The authors consider that the intraduodenal pressure is directly dependent on hypertrophy of the muscular layer of the duodenum wall. The formation of the duodenal stasis is followed by progressing elevation of the intraduodenal pressure, hypertrophy of myocytes, first hypertrophy and then atrophy of nerve cells of the ganglionic plexus.
