title: [Evaluation of enterogastric reflux using a modified scintigraphy method].
abstract: The aim of the study is evaluation of the clinical validity of the chosen and modified own model of the nuclear medicine method for the detection and quantification of enterogastric reflux (EGR), as well as evaluation of its clinical validity. The study was performed in 172 patients: with gastric and duodenal ulcer, after Billroth I and Billroth II gastrectomy, with gastroesophageal reflux, after cholecystectomy, with chronic cholecystitis and chronic duodenal disease. Acquisition was performed with gamma camera, during 90 minutes after intravenous application of 185 MBq 99m-Tc-Dietil IDA. Test meal was given in 30th minute, while gastric region was marked at the end of the study. On the basis of the radioactivity changes in the regions of the stomach and hepatobiliary system, presence of enterogastric reflux is determined and its index calculated. In all the groups of patients, values are significantly different from physiological. The most frequent occurrence and the largest quantity of reflux is present in patients after Billroth II gastrectomy with significantly different values from other groups of patients. The obtained results approve clinical value of the chosen and modified scintigraphy of EGR as a non-invasive and physiological method, which provides data about its presence and quantity.
