Acute necrotising pancreatitis - causes of deaths: single-centre retrospective study

Abstract

Relevance. There is a discussion about the prevalence of early or late mortality and the main causes of death in different phases of acute pancreatitis. Analysis of mortality is important for the determination of ways to improve the results of treatment of pancreatic necrosis.
 Aim of the research is analysis of the structure, timing characteristics and causes of deaths in pancreatic necrosis, the effect of the configuration of parapancreatitis and surgical tactics on the outcome of the disease.
 Materials and methods. Retrospective single-center study of lethal outcomes in acute pancreatitis was performed, the structure of mortality, cases of discrepancies in diagnoses, the timing of the onset and causes of deaths of patients were studied. The lethal outcomes were compared in the operated patients, the frequency of the mesentery root involvement, the indications and the timing of the interventions were assessed.
 Results. The ratio of early and late mortality was 45,2% to 54,8%, respectively. The main causes of early mortality – endotoxin shock and multi-organ failure, late one – infectious complications. In 9,6% of the patients, the diagnosis was made only with an autopsy. The prognostic value of the SOFA and SAPS II scales is characterized as low. The tactics of surgical treatment has changed in favour of minimally invasive surgery. The average conversion time for ineffective percutaneous procedures was 21,4 days. The involvement of mesentery in parapancreatitis was often accompanied by a breakthrough of the abscess into the abdominal cavity.
 Conclusion. The surgical component of the reduction in mortality is the rejection of unreasonable surgical interventions, the earlier conversion to "traditional" operations in case of ineffective minimally invasive treatment and the allocation of "central" localization of parapancreatitis as a serious prognostic factor of the course of severe pancreatitis.
