Visual Characteristic of Unaltered and Operated Stomach with the Help of Ultrasound Research

Abstract

The aim: to improve and implement stomach ultrasound examination in the diagnostic algorithm. Materials and methods. 100 people in the group of healthy individuals without stomach pathology and 100 in the group of patients operated on stomach with the use of noninvasive ultrasound diagnosis technology system were examined. There was an equal number of men and women among those examined (aged approximately 42.8 ± 12.3). The modified technique of trans-abdominal ultrasound stomach examination when the stomach is filled with liquid and its walls are medicamentally relaxed, and the technique of trans-abdominal ultrasound examination of an operated stomach were carried out with the help of scanning devices Aixplorer (Supersonic Imagine, France) and Accuvix V10 and Accuvix V20 (Medison, South Korea) in different modes of 2D-3D ultrasound imaging using curvilinear transducer, mini-curvilinear transducer, sector transducer, linear array transducer with frequency 3.5 to 7.5 MHz. The results were compared with the histomorphologic research data. Results. The major factors in the assessment of unchanged echostructure of gastric wall during gastroechography were the indicators of overall gastric wall thickness and thickness of its individual echo-layers, thickness and integrity of the mucin layer. The average gastric wall thickness normally made up 4.6 ± 0.3 mm (p < 0.001). The average gastric wall thickness of an operated stomach was as follows: on the 5-th day after surgery - 15.7 ± 2.7 mm; on the 10th day - 10.1 ± 1.17 mm; on the15 th day - 8.8 ± 0.6 mm; on the 25 day - 8.25 ± 2.3 mm; on the 30 th day - 7.0 ± 1.0 mm; in 2 months - 5,5 ± 0,5 mm; in 6 months - 5.6 ± 0.3 mm (p < 0.05). The ultrasound criteria of the norm with the assessment of mucin layer microcirculation that we have established provided us with the new data concerning an unchanged stomach echostructure. Dynamic ultrasound examination of an operated stomach at different terms after surgery helped to credibly assess the gastric stump and anastomosis condition to assist in predicting postoperative period course and choice of an effective tactics for further disease management. Conclusion. The results has proved the expediency of trans-abdominal ultrasound stomach examination usage in the system of standard abdominal organs diagnostics techniques.
