[Changes in the intracavitary pressure in the stomach and duodenum with different types of motility].

As many as 352 patients with different gastroenterological pathology (ulcer disease, chronic gastritis, chronic pancreatitis and cholecystitis) were examined under clinical conditions. Intracavitary pressure and gastric and duodenal motility were recorded on a "Salyut" polygraph with the aid of a tube of original design. It has been discovered that intracavitary pressure in the stomach and duodenum is biphasic in nature and that it may change not only in different diseases but also at different motility types. The changes discovered should be taken into account in administering adequate therapy.
