[A method of studying microcirculation in the gastric and duodenal walls]

The paper is concerned with the results of clinical application of a new method of investigation of microcirculation in the gastric and duodenal wall. The method is based on the administration of a radiopharmaceutical in the submucous layer of the stomach and duodenum through the bioptic channel of a gastroscope with further recording of its rate of discharge on a gamma-chamber. A total of 48 patients with different gastroduodenal diseases were investigated. Good reproducibility of the method and good correlation of its results with clinical findings were confirmed.
