CT in the diagnosis of nontraumatic acute abdomen

Purpose. Evaluation of the morbidity structure and demonstration CT-semiotics of the main diseases in patients with nontraumatic acute abdomen. Materials and methods. 905 studies of the abdomen performed in 2016 in the State Clinical Hospital named after S.P. Botkin in patients with acute abdomen. The studies were conducted natively, with contrasting per os, with intravenous enhancement, depending on the expected pathology. Results. The most common causes of acute abdomen were: acute intestinal obstruction (27[%]), pancreatitis (9[%]), urolithiasis and its complications (8[%]), oncology directly and its complications (7[%]), inflammatory changes in the gallbladder and diliary ducts (4[%]), inflammatory changes in the kidneys (3[%]). Also significant weight in the structure of morbidity was perforation of the bowel (2.5[%]), mesenteric thrombosis (2[%]), extraorganic inflammatory changes (2[%]). Only 5[%] of cases failed to reliably detect signs of a pathological process in the presence of a clinical pictu
