METHOD FOR CARRYING OUT DIFFERENTIAL EVALUATION OF FUNCTIONAL ACTIVITY DEGREE OF SMALL INTESTINE Russian patent published in 2004 - IPC

FIELD: medicine. SUBSTANCE: method involves carrying out transabdominal ultrasonic B-mode examination with additional colored doppleroflowmetric scanning and evaluating small intestine discharge flow rate using color and pulsating dopplerometric techniques at the moment of its peristaltic contraction. External small intestine diameter being found equal to or less than 20 mm, small intestine wall thickness being equal to 3-5 mm, retained intestinal mucous membrane folding, non-uniform intestine content alternating with segments filled with air, when carrying out transabdominal ultrasonic B-mode examination of small intestine content flow as echo moving in intestine tube lumen of various directions, colored in various colors from yellow-red to blue spectrum in colored doppleroflowmetric scanning mode, availability of peristalting small intestine segment in broad tracing zone of ultrasonic transducer, with given periodic accelerations and retardations of moving wall and intestine content with relative rest periods manifesting itself as 10-30 s long no-peristalsis periods determined on pulsating type dopplerometric device, relative rhythmic alternating succession of waves with content flow rate intensity equal to 10-30 cm/shaving low intensity value of 2-4 cm/s and optional relative rare hard peristaltic increases in content flow rate intensity>20-30 cm/s, sufficient intestinal amplitude mobility, retained intestinal tube compliance when pressing with transducer, normal small intestine peristalsis is to be diagnosed. Normal external small intestine diameter being retained, small intestine wall thickness being equal to 3-5 mm, marked intestinal mucous membrane folding, non-uniform anechogenous intestine content being available in small intestine lumen, high amplitude range of wall motion, clear and marked bright coloring of peristalting small intestine content under arrhythmic contraction conditions, continuously recorded relatively frequent peristalsis and small intestine content passage with small intestine content flow being recorded as echo moving in intestine tube lumen of various directions and having turbulent whirls, determining flow of excessive brightness colored in various colors from yellow-red to blue spectrum, intestine wall performing high speed motions, rare relative rest periods manifesting itself as 5-10 s long noperistalsis periods, prevalence of waves with content flow rate intensity equal to 10-30 cm/s with rarely occurring low intensity values of 2-4 cm/s, retained intestine tube compliance when pressing with transducer, increased small intestine peristalsis is to be diagnosed. Normal external small intestine diameter being > 20-30 mm, small intestine wall thickness being equal to 2-5 mm, no intestinal mucous membrane folding, non-uniform intestine content with intestine segments filled with air being available, insufficient intestinal amplitude mobility and lack of coloring of peristalting small intestine content with low speed and amplitude peristalsis wave and low echo flow in intestine tube lumen with arrhythmic contraction conditions and content flow rate intensity values of 2-4 cm/s, reduced intestine tube compliance when pressing with transducer, being observable, feeble small intestine peristalsis is to be diagnosed. Normal external small intestine diameter being > 20- 30 mm, small intestine wall thickness being equal to 2-5 mm, no intestinal mucous membrane folding, non-uniform intestine content with intestine segments filled with air being available, no peristaltic contractions and lack of coloring of peristalting small intestine content, no small intestine content flow recorded, reduced intestine tube compliance when pressing with transducer being the case, lack of small intestine peristalsis is to be diagnosed. EFFECT: high accuracy of differential evaluation method. 6 dwg
