-Introduction -Acute pancreatitis is presented in its severe form between 10% and 15% of cases and is associated with high mortality. In the initial phase, evolution characterized by the onset of organ dysfunction and subsequently by the presence of pancreatic necrosis and its complications. Methods -It was performed a literature review with consultations in the following databases: PubMed, SciELO, Lilacs. Headings used were the following: acute pancreatitis, infection, pancreatic necrosis. Conclusion -The treatment of pancreatic necrosis, despite the advent of modern methods and techniques, is still challenging. Because of the multiplicity of aspects that may take the examination of each case, in view of the extent, severity and location of facilities within a patient's care, the treatment should be individualized for each case.RESUMO -Introdução -A pancreatite aguda se apresenta na sua forma grave entre 10% e 15% dos casos e está associada com alta mortalidade. Na fase inicial da evolução caracteriza-se pelo aparecimento de disfunções orgânicas e posteriormente pela presença de necrose pancreática e suas complicações. Método -Foi realizada revisão da literatura com consultas feitas nas seguintes bases de dados: Pubmed, Scielo, Lilacs. Os descritores cruzados foram os seguintes: pancreatite aguda, infecção, necrose pancreática. Conclusão -O tratamento da necrose pancreática, apesar do advento de modernos métodos e técnicas, ainda continua desafiador. Devido à multiplicidade de aspectos que pode assumir, a análise de cada caso, tendo em vista a extensão, gravidade e meios existentes no local de atendimento do paciente, é que deverá orientar o tratamento possível, sendo ele sempre individualizado a cada caso.

Background:The cholecistojejunal bypass is an important resource to treat obstructive jaundice due to advanced pancreatic cancer. Aim:To assess the early morbidity and mortality of patients with pancreatic cancer who underwent cholecystojejunal derivation, and to assess the success of this procedure in relieving jaundice. Method:This retrospective study examined the medical records of patients who underwent surgery. They were categorized into early death and non-early death groups according to case outcome. Results: 51.8% of the patients were male and 48.2% were female. The mean age was 62.3 years. Early mortality was 14.5%, and 10.9% of them experienced surgical complications. The cholecystojejunostomy procedure was effective in 97% of cases. There was a tendency of increased survival in women and patients with preoperative serum total bilirubin levels below 15 mg/dl. Conclusion:Cholecystojejunal derivation is a good therapeutic option for relieving jaundice in patients with advanced pancreatic cancer, with acceptable rates of morbidity and mortality.
