FIELD: medicine.
SUBSTANCE: method involves carrying out premedication, giving intubation narcosis, opening abdominal cavity and outer large intestine blood vessel is exposed over length of 5 cm. Blood circulation volume is reduced by 20-30% when compared to the initial one and corresponds to the first large intestine ischemia degree. To create the second ischemia degree, 2 direct branches of the outer blood vessel of the large intestine over 1 are tied with polypropylene thread on 5 cm long segment. To create the third ischemia degree, 4 direct branches of the outer blood vessel of the large intestine over 2 are tied with polypropylene thread on 5 cm long segment. Then the intestine is laid on its initial place and the wounds are sutured layer-by-layer.
EFFECT: enhanced effectiveness in reproducing large intestine changes dynamics closed to clinical course of the ischemic disease.
