METHOD FOR RESTORING A MOTOR- EVACUATORY INTESTINAL FUNCTION AFTER OPERATION CONDUCTED UPON THE ORGANS OF ABDOMINAL CAVITY AND DEVICE FOR ITS IMPLEMENTATION Russian patent published in 2002 - IPC

FIELD: medicine, surgical gastroenterology, medicinal equipment. SUBSTANCE: the method deals with earlier restoration of motor- evacuatory intestinal function during early post- operational period immediately after operations conducted upon the organs of abdominal cavity and, also, in case of peritonitis, acute pancreatitis, acute intestinal obstruction, and also after operations upon small and large intestines. The method includes intraoperational introduction of a probe with electrodes for the whole length of small intestine followed by electrostimulation against constant aspiration of intestinal content. Both opposite-polar electrodes are installed inside the lumen in anterior duodenal department. Electrostimulation is conducted with the series of monopolar impulses of low frequency being 12 in 1 min for 15-30 min. Then maintaining electrostimulation is carried out at series frequency being 15, 30, 60 sec/series. Device contains a nasointestinal probe and electrodes. Electrode of negative polarity is situated 12-14 cm after the first perforation opening of a probe. Electrode of positive polarity is situated 12-15 cm distally against a negative one. A surgeon conducts intubation of small intestine with a nasointestinal probe with electrodes at its length of not less than 200 cm. A probe is directed up to ileocecal corner. Both electrodes come behind the pylorus and stay in anterior duodenal department where the main drivers of intestinal peristaltic rhythm are situated. Stimulation is conducted with a current power corresponding to the threshold of intestinal stimulation which is equal to 3.5-5 mA, on the average. EFFECT: higher efficiency and simplified procedure of stimulation. 2 cl, 1 dwg
