Purpose. To use the capabilities of multi-detector computer tomography to clarify the CT semiotics of acute pancreatitis in various phases of its development. Materials and methods. The study included 60 patients, who applied to the Scientific Center of Surgery named after academician M.A. Topchubashev with the diagnosis of acute pancreatitis. The patients were divided into three groups depending on the severity of the disease determined by the results of primary CT studies: group I mild severity of the 1st3rd level on the Balthazar scale, 13 (21.7) patients group II moderate severity of 46 points, 22 (36.7) patients group III severe disease at the level of 710 points, 25 (41.7) patients with acute pancreatitis. Results and discussion. A mild form of acute pancreatitis in CT is characterized by moderate edema, infiltration in parapancreatic tissue and in gland tissue in bolus contrasting a weak level of contrast. In moderate acute pancreatitis in CT, the increase of the size of the parenchyma of the gland, decrease of densitometric parameters, limited infiltration in the peripancreatic area, and millimetric pancreonecrotic foci were observed. In case of native CT of severe form of acute pancreatitis, the following conditions were revealed: increase of the parenchyma of the gland and decrease of densitometric parameters, and worn outlines. On the CT scan with intravenous contrasting in the parenchyma of the gland, large necrotic changes, massive infiltration in the parapancreatic area, clusters (abscess) of the limited and thickened nature with air protrusions were observed. Pathological changes found in the parenchyma of the gland, its surrounding tissue, abdominal and thoracic cavities with the help of native CT and with contrast enhancement create conditions for determination of the severity of the disease and the choice of an adequate treatment strategy. Tactics of treatment is determined by the severity of acute pancreatitis. Conclusions. CT scan with intravenous contrast is the best method for visualizing ac [...]
