Estimation of the enterogastric reflux by modified scintigraphic method.
OBJECTIVE
The aim of the study was to introduce the chosen and modified model of the nuclear medicine method for the detection and quantification of enterogastric reflux, as well as evaluation of its clinical validity.


METHODS
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 a gamma camera, during 90 min after intravenous application of 185MBq 99mTc-Dietil IDA. Test meal was given in the 30th minute, while the 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, the presence of enterogastric reflux was determined and its index calculated.


RESULTS
In all the groups of patients, values were significantly higher than in the controls (P < 0.05). The most frequent occurrence and the largest quantity of reflux was present in patients after Billroth II gastrectomy with significantly different values from other groups of patients (P < 0.05).


CONCLUSIONS
The obtained results approve clinical value of the chosen and modified scintigraphy of enterogastric reflux, as a non-invasive and physiological method, which provides exact data about its presence and quantity.
