ABSTRACT

ABSTRACT BACKGROUND: Bile duct injury is a life-threatening complication that requires proper management to prevent the onset of negative outcomes. Patients may experience repeated episodes of cholangitis, secondary biliary cirrhosis, end-stage liver disease and death. OBJECTIVE: To report a single center experience in iatrogenic secondary liver transplantation after cholecystectomy and review the literature. METHODS: This was a retrospective single center study. Of the 1662 liver transplantation realized, 10 (0.60 %) were secondary to iatrogenic bile ducts injuries due cholecystectomies. Medical records of these patients were reviewed in this study. RESULTS: Nine of 10 patients were women; the median time in waiting list and between cholecystectomy and inclusion in waiting list was of 222 days and of 139.9 months, respectively. Cholecystectomy was performed by open approach in eight (80%) cases and by laparoscopic approach in two (20%) cases. The patients underwent an average of 3.5 surgeries and procedures before liver transplantation. Biliary reconstruction was realized with a Roux-en-Y hepaticojejunostomy in nine (90%) cases. Mean operative time was 447.2 minutes and the median red blood cell transfusion was 3.4 units per patient. Mortality in the first month was of 30%. CONCLUSION: Although the liver transplantation is an extreme treatment for an initially benign disease, it has its well-defined indications in treatment of bile duct injuries after cholecystectomy, either in acute or chronic scenario.


RESUMO CONTEXTO: A lesão da via biliar é uma complicação que pode ameaçar a vida e que requer manejo adequado para prevenir o aparecimento de desfechos negativos. Os pacientes podem apresentar episódios repetidos de colangite, cirrose biliar secundária, doença hepática terminal e até mesmo morte. OBJETIVO: Avaliar a experiência de um único centro em transplante hepático secundário a lesão iatrogênica de via biliar pós-colecistectomia e fazer uma revisão de literatura. MÉTODOS: Este foi um estudo retrospectivo de um único centro. Dos 1662 transplantes de fígado, 10 (0,60%) foram secundários a lesões iatrogênicas das vias biliares devido à colecistectomias. Os prontuários médicos desses pacientes foram revisados neste estudo. RESULTADOS: Nove dos dez pacientes eram mulheres; o tempo médio em lista de espera de transplante e entre colecistectomia e inclusão na lista de espera foi de 222 dias e de 139,9 meses, respectivamente. A colecistectomia foi realizada por abordagem aberta em oito (80%) casos e por abordagem laparoscópica em dois (20%) casos. Os pacientes foram submetidos a uma média de 3,5 cirurgias e procedimentos antes do transplante de fígado e a reconstrução biliar foi realizada com hepaticojejunostomia em Y-de-Roux em nove (90%) casos. O tempo operatório médio foi de 447,2 minutos e a média de transfusão de concentrados de hemácias foi de 3,4 unidades por paciente. Mortalidade no primeiro mês foi de 30%. CONCLUSÃO: Embora o transplante de fígado seja um tratamento extremo para uma doença inicialmente benigna, ele tem suas indicações bem definidas no tratamento de lesões biliares após colecistectomia, seja em um cenário agudo ou crônico.

ABSTRACT

Epstein-Barr virus (EBV) has been associated with 10% of gastric carcinomas. The aim of this study was to determine the frequency of EBV in gastric carcinomas in Brazil assessed by in situ hybridization (ISH) and PCR, which would contribute to the characterization of the clinical and pathological aspects of EBV-associated gastric carcinomas. One hundred and ninety-two gastric carcinoma cases were collected at hospitals in two Brazilian states. Seventy-three out of 151 cases were PCR(+), while 11/160 cases were ISH(+). Nine out of eleven ISH(+) cases displayed a diffuse staining pattern and 2 out of 11 a focal pattern. Both techniques showed that the EBV(+) cases were characterized by their association with males, older patients, lower gastric region, intestinal type, advanced stage and poorly to moderately differentiated tumors. The concordance between the two techniques was 55.8% (Cohen's kappa index = 0.034). Four cases were ISH(+)/PCR(-), while 49 cases were PCR(+)/ISH(-). Only two cases showed stained lymphocytes by ISH and one of them was PCR(-). The observed discrepancy between the two techniques could not be explained just by the elevated accuracy of PCR. ISH(+)/PCR(-) carcinomas may be encountered if EBV is not present in the whole tumor tissue or if there are polymorphisms in the sequences of the viral genome amplified. On the other hand, the high frequency of PCR(+) results associated with the absence of ISH staining in lymphocytes and/or tumors cells suggests that the virus may be present in tumor cells or other cell types without expressing EBER1, the target of the ISH technique.

ABSTRACT

INTRODUÇÃO: O vírus Epstein-Barr (EBV) está associado a cerca de 10 por cento dos adenocarcinomas gástricos, representando mais de 50 mil casos por ano no mundo. Apesar dos estudos realizados em várias partes do mundo, alguns aspectos clinicopatológicos permanecem controversos. OBJETIVOS: O presente estudo teve como objetivo analisar as características clinicopatológicas de casos de adenocarcinomas gástricos procedentes dos estados de São Paulo e Ceará, correlacionando-os com a detecção de EBV. MATERIAIS E MÉTODOS: Foram obtidos 192 casos de adenocarcinomas gástricos de hospitais dos estados de São Paulo e do Ceará, dos quais 160 foram submetidos à técnica de RNA-hibridização in situ para detecção de EBV. RESULTADOS: Dos 160 casos, 11 (6,9 por cento) foram EBV-positivo, exibindo intensa marcação nuclear em células tumorais. Destes, dois casos também apresentaram linfócitos infiltrados marcados. Não encontramos marcação em tecido normal ou pré-neoplásico. São Paulo e Ceará apresentaram as frequências 3/60 (5 por cento) e 8/100 (8 por cento), respectivamente, e maior relação do EBV com indivíduos do sexo masculino, de idade avançada, com tumores do tipo intestinal, de estadiamento elevado e grau pouco a moderadamente diferenciado. Os casos do Ceará exibiram aumento relativo de tumores EBV(+) localizados na cárdia, enquanto os casos de São Paulo demonstraram aumento naqueles localizados no corpo gástrico. CONCLUSÃO: A frequência de tumores EBV(+) do presente estudo situa-se nos valores descritos na literatura mundial. Entre os achados, um deles não encontra paralelo na literatura mundial e refere-se ao elevado percentual de tumores EBV(+) no corpo gástrico observado nos casos de São Paulo.


INTRODUCTION: The Epstein-Barr virus (EBV) has been associated with approximately 10 percent of gastric adenocarcinomas, which represents more than 50,000 cases/year worldwide. Despite the studies undertaken in several countries, some clinical-pathological aspects remain contentious. OBJECTIVE: The objective of this study was to analyze clinical-pathological features of gastric adenocarcinomas from two Brazilian states, São Paulo and Ceará, by correlating them with EBV detection. MATERIALS AND METHODS: One hundred ninety-two gastric adenocarcinoma cases were selected from hospitals in São Paulo and Ceará, of which 160 were submitted to RNA in situ hybridization for EBV detection. RESULTS: Eleven (6.9 percent) out of 160 cases were EBV-positive with intense nuclear staining in tumor cells. Among these, two cases also showed stained infiltrating lymphocytes. There was no staining in normal or preneoplastic tissue. São Paulo and Ceará yielded the respective results: 3/60 (5 percent) and 8/100 (8 percent). In both states, EBV was more prevalent among elder male patients with little to moderately differentiated intestinal tumors in advanced stage. Ceará cases substantiated a relative increase in EBV(+) tumors located in the cardia, whereas São Paulo cases presented an increase in the gastric corpus. CONCLUSION: The frequency of EBV(+) tumors is similarly described in the literature. Among our findings, the elevated percentage of EBV(+) tumors in the gastric corpus, which was observed in São Paulo cases, is unprecedented in the literature.

ABSTRACT

O bezoar compreende o acúmulo de substâncias não-digeríveis (folhas, pêlos, pedras, produtos lácteos, medicamentos, entre outros) no trato digestório. Sua importância deve-se ao quadro clínico por vezes inespecífico e às complicações que podem surgir. Apresentamos aqui o caso de uma paciente de 62 anos atendida no serviço de Cirurgia Oncológica com quadro de um mês de evolução e suspeita inicial de neoplasia colorretal. Exames complementares não elucidaram o diagnóstico, que só foi feito após abordagem cirúrgica por laparotomia exploratória. Após a mesma, a paciente evoluiu com piora do estado geral e foi transferida para a UTI do hospital, falecendo devido a complicações septicêmicas. Esse caso demonstra as dificuldades para se chegar nesse diagnóstico e que o atraso pode resultar em complicações letais para o paciente.


Bezoar is a foreign body in the digestive tract originated from ingestion of non-digestible substances (leaves, hair, rocks, milk products, drugs, etc). Undetermined clinical signs and severe complications make it an important diagnosis. We report the case of a 62-year-old female patient who was seen at the oncological surgery department of Santa Casa de Misericórdia de Fortaleza. The patient reported having low gastrointestinal symptoms for a month. Colorectal neoplasia was initially suspected. Blood and image diagnostic tests were not elucidative. The diagnosis was just confirmed after surgical approach. The patient had a poor postoperative follow-up and died after complications of septicemia. This case demonstrates the difficulties to confirm such diagnosis and the lethal complications caused by diagnosis delay.
