ABSTRACT
Abstract Background: Bleeding as a complication is associated with poorer results in cardiac surgery. There is increasing evidence that the use of blood products is an independent factor of increased morbidity, mortality, and hospital costs. Dyke et al. established the universal definition of perioperative bleeding (UDPB). This classification is more precise defining mortality in relation to the degree of bleeding. Methods: A descriptive and analytical retrospective study of a database of patients underwent cardiac surgery from January 1, 2016, to December 31, 2017, was performed. The primary objective of the study was to look at mortality associated with the degree of bleeding using the UDPB. Results: A total of 918 patients who went to cardiac surgery were obtained. Most of the population was classified as insignificant bleeding class (n = 666, 72.9%), and for massive bleeding the lowest proportion (n = 25, 2.7%). For the primary outcome of 30-day mortality, a significant difference was found between the groups, observing that it increased to a higher degree of bleeding. This was corroborated by multivariate logistic regression analysis that was adjusted to EuroScore II and cardiopulmonary bypass (CPB) duration, finding an independent association of the bleeding class with 30-day mortality (OR, 95%, 5.82 [2.22-15.26], p = 0.0001). Conclusions: We found that the higher the degree in UDPB was associated with higher mortality independently to EuroScore II and CPB duration for adult patients undergoing cardiac surgery.
Resumen Antecedentes: El sangrado como complicación está asociado a peores resultados en cirugía cardiaca. Existe una evidencia cada vez mayor que la transfusión de productos sanguíneos por si solo es un factor independiente de incremento en la morbilidad, mortalidad, y costos hospitalarios. Dyke y colaboradores establecieron la definición universal de sangrado perioperatorio. Esta clasificación es más precisa en definir mortalidad en relación con el grado de sangrado. Material y métodos: Se realizo un estudio descriptivo y analítico de tipo retrospectivo de una base de datos de pacientes que fueron a cirugía cardiaca del 1 enero del 2016 al 31 de diciembre del 2017. El objetivo primario del estudio fue observar la mortalidad asociada con el grado de sangrado utilizando la definición universal de sangrado perioperatorio. Resultados: Se obtuvieron un total de 918 pacientes que fueron a cirugía cardiaca. La mayor parte de la población fue clasificada como clase de sangrado insignificante (n = 666, 72.9%), y para sangrado masivo la menor proporción (n = 25, 2.7%). En el desenlace primario de mortalidad a 30 días se encontró una diferencia significativa entre los grupos, observando que aumentada a mayor clase de sangrado. Esto fue corroborado mediante un análisis multivariado regresión logística que fue ajustado a con EuroScore II y el tiempo de bomba de circulación extracorpórea, encontrando una asociación independiente de la clase de sangrado con mortalidad a 30 días (OR, 95%, 5.82 [2.22-15.26], p = 0.0001). Conclusiones: Encontramos que cuanto mayor era el grado en la UDPB se asociaba con una mayor mortalidad independientemente de EuroScore II y la duración del bypass cardiopulmonar para pacientes adultos sometidos a cirugía cardíaca.

RACIONAL: No Brasil existe escassa publicação científica destinada à divulgação dos resultados das ressecções pancreáticas. OBJETIVO: Apresentar os resultados cirúrgicos das ressecções pancreáticas. MÉTODOS: Analisou-se prospectivamente 54 casos consecutivos de pacientes submetidos à pancreatectomias. Foi avaliada a ocorrência de complicações pós-operatórias (fístula pancreática, retardo do esvaziamento gástrico e hemorragia pós-operatória) fundamentadas nos critérios dos Grupos Internacionais de Estudo sobre a Definição de Fístula Pancreática e de Cirurgia Pancreática. RESULTADOS: Das 54 pancreatectomias, 32 foram realizadas em mulheres (59,26%) e 22 em homens (40,74%). A média de idade dos pacientes foi de 54,5 anos. O procedimento mais praticado foi à cirurgia de Whipple em 38 pacientes. Em oito destes, houve ressecção do eixo mesentérico-portal. O tempo médio de internação foi de 20,7 dias. A maioria dos pacientes (51%) esteve internada por até 10 dias. A fístula pancreática foi observada em 50% da amostra em 44,7% dos pacientes submetidos à operação de Whipple. O sangramento pós-operatório e o retardo do esvaziamento gástrico nos pacientes submetidos à essa operação ocorreram, respectivamente, em 13,15% e 18,41%. Na amostra a taxa global de morbidade e mortalidade foi respectivamente de 62,9% e 5,5%. CONCLUSÃO: Há necessidade das publicações nacionais assimilarem os conceitos e critérios apresentados pelas classificações GIEDFP e GIECP para permitir a comparação dos resultados obtidos com o tratamento cirúrgico de doenças pancreáticas, no contexto brasileiro. Quem sabe, se o grande avançado visto nos últimos 40 anos em termos de redução das taxas de mortalidade associadas com ressecções pancreáticas também pode ocorrer com os níveis persistentemente elevados de complicações pós-operatórias.
BACKGROUND: Scientific publications focusing on the results of pancreatic resections in Brazil are scarce. AIM: To present the surgical results of pancreatic resections. METHODS: Were analyzed prospectively 54 consecutive cases of patients undergoing consecutive pancreatectomy evaluating the occurrence of postoperative complications (pancreatic fistula, delayed gastric emptying and postoperative hemorrhage) based on the criteria of the International Study Group on Pancreatic Fistula Definition and International Study Group of Pancreatic Surgery. RESULTS: Of the 54 pancreatectomy, 32 occurred in women (59,26%) and 22 in men (40,74%). The mean age of patients was 54,5 years. The most performed procedure was the Whipple operation, in 38 patients. In eight of those cases, mesenteric-portal confluence was ressected. The mean period of hospitalization was 20,7 days. The hospitalization in 51% of patients was up to 10 days. A pancreatic fistula was observed in 50% of the cases submitted to the Whipple surgery. The postoperative hemorrhage and delayed gastric emptying in patients undergoing the surgery occurred respectively in 13,15% and 18,41%. The overall morbidity and mortality was respectively 62.9% and 5.5%. CONCLUSION: There is a need for the national publications to assimilate the concepts and criteria presented by the ISGFP² and ISGPS23,25 to enable comparison of the results obtained with surgical treatment of pancreatic disorders, in the Brazilian context. Who knows, therefore, whether the great advanced seen in the last 40 years in terms of the reduction in mortality rates associated with pancreatic resections may also occur with the persistently high levels of postoperative complications.
