METHOD FOR INTRAOPERATIONAL ULTRASOUND DIAGNOSTICS FOR THE STATE OF COLONIC WALL IN CASE OF CHRONIC INFLAMMATORY COMPLICATIONS OF DIVERTICULAR DISEASE

FIELD: medicine, coloproctology. ^ SUBSTANCE: in area of operation field it is necessary to put a linear ultrasound sensor for scanning to carry out ultrasound colonic testing at scanning frequency being 7.5 MHz with the series of transverse, longitudinal and oblique scanning sections. It is necessary to analyze tomographic pictures to detect the most altered colonic segment. In case of mucosal prolapsing into thickened muscular colonic layer one should diagnose the presence of pseudodiverticula without coming beyond colonic contours. In case of insignificant diverticular coproliths and those in narrow and deep haustra, in case of increased mucosal folding - "the symptom of hyperhaustration" - one should diagnose diverticular colonic disease. At visualizing uneven external contour due to diverticular protrusion and thickening of periintestinal fiber one should diagnose diverticulitis. At visualizing small-sized liquid formations of incorrect shape in sigmoid mesentery one should diagnose the destruction of diverticular wall along with developing a paraintestinal cavity. At visualizing interfused altered colonic segment and near-by organs, visualization of liquid formations between them or being near to them, at the presence of either homogeneous or nonhomogeneous structure with gaseous bubbles, and, also, at visualizing either narrow or wide hypoechogenic pathways at the presence of gaseous bubbles inside them that connect the fused organs one should diagnose inflammatory infiltrates, abscesses and fistular pathways in abdominal cavity. At detecting the altered segment as a result of ultrasound colonic testing at the thickness of muscular layer being about 2-3 mm, not more at simultaneous absence of mucosal prolapsing into muscular layer it is possible to conclude upon the line for potential resection to be the area situated above and under this segment. The innovation enables to obtain necessary information to affect the detection of colonic resection borders considerably. ^ EFFECT: higher accuracy of diagnostics. ^ 1 cl, 3 ex
