POSSIBILITIES OF E.J.BALTAZAR CLASSIFICATION IN ULTRASOUND DIAGNOSTICS OF ACUTE PANCREATITIS FOR PREDICTION OF ITS SEVERITY

Aim: to evaluate the possibilities of ultrasound imaging in the diagnosis of acute pancreatitis and criteria of E.J. Balthazar classification according to the results of computer tomography of the pancreas.Material and methods. An ultrasound study of 390 patients with acute pancreatitis was performed, among which 285 (73%)were mild, 88 (22,5%) moderate and 17 (4,5%) severe. The study was conducted at the time of hospitalization, in the absence of visualization of the pancreas within 48-72 hours after hospitalization.Results. Ultrasound criteria for pathological changes in the pancreas are proposed in accordance with the computer tomographic classification of acute pancreatitis according to E.J. Balthazar. The diagnostic effectiveness of ultrasound in acute pancteatitisreached 96,5%, sensitivity and specifity - 84,7 and 78,4% respectively, according to our data.Conclusions. 1) Ultrasound reveals signs of acute pancreatitis, determined by CT according to E.J. Balthazar classification. 2) Рatients with stage B and C by E.J. Balthazar classification have mild course of acute pancreatitis with no complications. Most complications are noted in patients with stage D and E of this classification. 3) The use of the Balthazar classification in ultrasound allows predicting the severity of acute pancreatitis and detecting patients with high risks for complications development.
