FIELD: surgery.SUBSTANCE: used to predict the effectiveness of treatment of acute pancreatitis in the early stages. On the 1st, 4th, 7th and 11th days after hospitalization, venous blood sampling is performed from patients, the level of C-reactive protein, the activity of phospholipase A2 and alpha-amylase in the blood is assessed, and an ultrasound of the abdominal cavity is performed to identify fluid formation in the abdominal cavity. In patients with acute pancreatitis, the probability of developing complications IRO is calculated using the stated formula. With the IRO value less than 3.1 predicts high treatment effectiveness, indicating the absence of the likelihood of complications. With an IRO value from 3.2 to 4.5, average treatment effectiveness is predicted, indicating possible disease progression and development of complications and the need for constant monitoring. If the IRO value is more than 4.5, the treatment is predicted to be ineffective, indicating a high probability of complications and requiring urgent puncture interventions at the site and adjustments to treatment regimens.EFFECT: method provides the possibility of increasing the accuracy of assessing the treatment of acute pancreatitis in the early stages, predicting the course of acute pancreatitis and optimizing treatment by preventing the risk of fluid formations, due to the assessment of the state of the components of the homeostasis system: pancreatogenic, immunoinflammatory, membrane-destabilizing, and visual diagnostics of the abdominal cavity to identify fluid formations in it.1 cl, 4 tbl, 3 ex
