METHOD FOR DETERMINING THREAT OF GASTRODUODENAL PEPTIC ULCER HEMORRHAGE

摘要

FIELD: medicine.;SUBSTANCE: method involves recording ulcer tissue redox potential by introducing active platinum needle-shaped electrode in perpendicular to mucous membrane plane to a depth of 2 mm via fibrogastroduodenoscope. Redox potential magnitude being equal to or greater than 70 mV, tissue state is determined as progressive ischemic necrosis with a threat of bleeding recidivation, the value being less than 70 mV, tissue state is determined as ischemic lesion without bleeding recidivation threat.;EFFECT: high accuracy of prognosis.
