FIELD: medicine. SUBSTANCE: method involves carrying out transabdominal gastrosonography for recording metric parameters of anatomical structures of pylorus-modeling sphincter and determining its functional abilities, availability or lack of duodenal reflux. Muscle union volume of pylorus-modeling sphincter is additionally determined from V1-V2 formula where V1 is the sphincter cylinder volume inside of external surface and V2 is the sphincter cylinder volume inside of internal muscular stomach wall envelope surface at the level of pylorus-modeling sphincter. Its external forming muscular duplicature thickness uniformity, percent ratio of postoperative cicatrix to sphincter muscular duplicature over external contour when performing transverse ultrasonic scanning are also determined in the course of endoscopic gastroduodenal junction. Liquid layers between sphincter layers are measured in early postoperative period and blood circulation rate is evaluated in pylorus-modeling sphincter contour. Muscle union volume of pylorus-modeling sphincter being equal to cm3, its external forming muscular duplicature thickness being uniform in thickness, postoperative cicatrix being equal to 6% in length with respect to sphincter muscle duplicature circumference along the external boundary when performing ultrasonic scanning, no additional liquid being observed between sphincter layers and on its external boundary, blood vessels being visualized on the pylorus-modeling sphincter contour, anatomical and functional full value of muscle union of pylorus-modeling sphincter in postoperative period is determined. Muscle union volume of pylorus-modeling sphincter being equal to 3,0 cm3, its external forming muscular duplicature thickness being uniform in thickness, postoperative cicatrix being greater than 6% in length with respect to sphincter muscle duplicature circumference along the external boundary when performing transverse ultrasonic scanning, additional liquid being available between sphincter layers or on its external boundary, no blood vessels being visualized on the pylorus-modeling sphincter contour, anatomical and functional deficiency of muscle union of pylorusmodeling sphincter in postoperative period is determined. EFFECT: high reliability of evaluation. 7 dwg |
