摘要：
FIELD: medicine.SUBSTANCE: technique involves transabdominal ultrasonography of jejumum and colon in longitudinal and transversal projections. The transabdominal ultrasonography is native with the patient positioned on his/her back. Visualising all the jejuneal segment involves taking intestinal loops without haustra as reference points. haustra are used as reference points for visualising the colon. pulsed Doppler velocimetry is conducted to determine a blood flow velocity in mesenterial arterial branches. A transperineal examination of the anorectal area is performed in the patient placed on his/her left side with bended knees. A sensor is placed into an anal pit directly and displaced from pubic to sacrum while scanning in two projections - longitudinal and longitudinal-oblique. The reference points are sacrum, symphysis, and anal canal. The state of a distal portion of rectal ampulla is assessed. The derived values are compared to the normal criteria. If observing any changes in the jejunum: wall thickening more than 2 mm, higher echogenicity, intestinal lumen narrowing if observing any changes in the colon: haustra flatness, contour roughness, wall thickening more than 2.5 mm, mucosal thickness more than 1 mm, submucosal thickness more than 0.5 mm, the absence of clear layer differentiation, higher submucosal echogenicity, intestinal lumen narrowing, higher blood flow velocity in the mesenterial arterial branches more than 7.0 cm/sec changes in adjoining organs: higher echogenicity of the greater omentum, envelopment of the jejuneal and colonic loops involved into the inflammatory process with the omentum, lengthening of the mesenterial, para-aortic lymph nodes more than 10 mm, free abdominal fluid, the changes in the anorectal area: rectal ampulla wall thickening more than 2.5 mm, higher echogenicity of perineal subcutaneous fat, anorectal fistulas and paraproctitis testify to the presence of colonic and jejuneal wall hyperplasia in the involved portions, mese
