METHOD FOR EVALUATING TOPOGRAPHO-ANATOMICAL STRENGTH OF PYLORUS Russian patent published in 2006 - IPC A61B8/00 

FIELD: medicine.

SUBSTANCE: it is necessary to carry out ultrasound testing of pylorus followed by evaluating its position against the axis of gastroduodenal transition and its metric characteristics. Additionally, one should conduct pyloric ultrasonography to detect the value of the volume of its muscular weight according to the value of pyloric index calculated as the product of the length of the segment of pyloric cross-sectional muscular fibers and the value of its width in longitudinal ultrasound section of gastroduodenal transition against the axis of gastro-intestinal tube (mm²), detect the value of pyloric diameter along its external contour being perpendicular against the axis of gastroduodenal transition, detect in degrees the topography of the segment of pyloric cross-sectional muscular fibers against the axis of gastroduodenal transition, detect the shape of the segment of pyloric cross-sectional muscular fibers: linear (band-shaped); triangular; butterfly-shaped; spindle-shaped; N-shaped; sickle-shaped (semilunar); the steadiness by the thickness of the segment of pyloric cross-sectional muscular fibers; the thickness of pre-pyloric muscular layer of gastric wall, the value of pyloric lumen in the course of its opening at peristalsis; the value of pyloric defect according to the lumen beyond its peristalsis. At the value of pyloric index being 61-175 mm², pyloric diameter by its external contour up to 25 mm, the availability of acute angle of the disposition of the segment of pyloric cross-sectional muscular fibers against the axis of gastroduodenal transition, and at cross-sectional angle of disposition only in combination with pyloric index of 70 mm², not less against pyloric muscular weight, linear or band-shaped, N-shaped, sickle-shaped forms of the segment of pyloric cross-sectional muscular fibers, its steady thickness, the thickness of pre-pyloric muscular layer of gastric wall of 4-5 mm, the value of pyloric lumen in the course of its opening at peristalsis ranged 5-15 mm, the absence of pyloric defect by the lumen beyond its peristalsis one should diagnose normal topographo-anatomical state of pylorus. At the value of pyloric index being above 175 mm² or 60 mm² and less, at pyloric diameter along its external contour being above 25 mm, the availability of cross-sectional angle of the disposition of the segment of pyloric cross-sectional muscular fibers against the axis of gastroduodenal transition in combination with pyloric index up to 60 mm² of pyloric muscular weight, at triangular, butterfly-shaped, spindle-shaped forms of the segment of pyloric cross-sectional muscular fibers, its unsteady thickness, the thickness of pre-pyloric muscular layer of gastric wall being below 2-3 mm and above 5 mm, the value of pyloric lumen in the course of its opening at peristalsis being 5 mm or above 15 mm, registering the pyloric defect according to the lumen of any size beyond its peristalsis one should diagnose pyloric topographo-anatomical failure.

EFFECT: higher accuracy of evaluation.
