METHOD FOR DIFFERENTIAL DIAGNOSIS OF CHRONIC ADHESIONS OF PERITONEUM AND ACUTE ADHESIVE INTESTINAL OBSTRUCTION Russian patent published in 2018 - IPC A61B6/03 A61K49/06 A61P43/00 A61K33/00 A61P39/00 

FIELD: medicine.

SUBSTANCE: invention relates to medicine, namely to surgery and roentgenology, and can be used in the differential diagnosis of chronic peritoneal adhesion (CPA) and acute adhesive intestinal obstruction (AAIO). Introduce to the patient per os mixture containing 0.3 g of contrast preparation Unigegsola, 4.0 g “Polysorb MP” per 1.0 liter of cold mineral water with gas. After 15 minutes, an X-ray contrast tomographic examination of the abdominal cavity is performed with a tomograph increment of 5.0–10 mm. Analyze the received tomograms of the abdominal cavity. Construct a 3D model of intestinal loops performed by this X-ray contrast mixture. Determine the presence of dilated bowel loops, inner and outer diameters of the small intestine, the thickness of the wall of the small intestine, the nature of the contents of the intestine, presence of infiltrates in the abdominal cavity, the density of the contents of the small intestine, the presence of fluid in the abdominal cavity. In absence of dilated intestinal loops, the diameter of the small intestine is less than 24 mm in internal diameter, diameter of the small intestine is less than 29 mm, the thickness of the small intestine wall is less than 3.0 mm, the absence of gas and the presence of feces in the small intestine, the absence of infiltrates in the abdominal cavity, density of intestinal contents – 61.5±14.0 units of Hounsfield, absence of fluid in the abdominal cavity are diagnosed with CPA. When visualizing the dilated loops of the intestine, the diameter of the small intestine is greater than 35 mm, the diameter of the small intestine is more than 39 mm in outer diameter, the thickness of the small intestine wall is more than 4.0 mm, presence of gas and the absence of feces in the small intestine, the presence of infiltrates in the abdominal cavity, the density of the contents of the gut – 23.4±12.0 units of Hounsfield, the presence of fluid in the abdominal cavity is diagnosed with AAIO.

EFFECT: method provides an increase in the accuracy of the differential diagnosis of CPA and AAIO and prevention of complications due to the objectification of the obtained tomographic data and the use of an X-ray contrast mixture per os.
