”Fulminant” acute pancreatitis: diagnosis, prognosis, treatment

Abstract

Aim:improving the results treatment of patients with severe acute pancreatitis by early diagnosis fulminant course of the disease and development of individualized treatment tactics based on early surgical interventions with perioperative extracorporeal detoxificationMaterials and methods:In research analyzed the treatment of 232 patients with severe acute pancreatitis: 175 patients were evaluated retrospectively (control group), 57 were included in a prospective study (main group). The severity of the disease was studied using integral scales, necrosis of the pancreas (its localization, depth) and the prevalence of parapancreatitis (gradations according to Ishikawa et al.) - according to CT data. The tactics of treatment at the retrospective stage of the study was based on the current Clinical Recommendations, at the prospective stage - on the developed signs of a "fulminant" course of the disease and included early operations with perioperative extracorporeal detoxification.Results:Criteria for a fulminant course of severe acute pancreatitis were found in 41 (23%) of 175 and 24 (42%) of 57 patients. According to the scale values (APACHE II ≥ 16 Ranson ≥ 8, SOFA ≥ 7 points) in the first 48 hours from the onset of the disease, the presence of aseptic enzymatic peritonitis, the depth of necrosis in the region of the head and body of the pancreas ≥50%, intra-abdominal hypertension of the III-IV degree, significant differences with similar indicators in 134 and 33 patients with severe acute pancreatitis. With fulminant course in the control and main groups, all 5 patients who received only conservative treatment died, 33 (86.8%) and 9 (40.9%) after operations, χ2 = 13.32, p<0.001. Mortality in severe acute pancreatitis, excluding patients with fulminant course, was comparable in the groups, being 15.7% and 15.2%, χ2 = 0.450, p> 0.05.Conclusion:Patients with severe acute pancreatitis represent a heterogeneous group. The morphological substrate of "fulminant" pancreatitis is deep (more than 50%) necrosis with localization in the head and body of the pancreas and widespread parapancreatitis. The developed individualized approach to treatment allows predicting an unfavorable course in the first 48 hours after the onset of the disease. Early operations in the nature of detoxification, decompression and drainage interventions, with perioperative use of extracorporeal detoxification methods allowed to reduce mortality from 86.8% to 40.9%.
