Pancreaticoduodenectomy is the only curative treatment for pancreatic head tumors. The possibility to achieve a potentially curative surgical treatment is limited to patients in which a complete tumor resection can be performed with free surgical margins. In a small number of patients with localized pancreatic cancer, negative margins are only accomplished with portal vein resection. Pancreaticoduodenectomy is often avoided in these patients due to the mistaken concept that venous resection may be followed by higher mortality and carries poorer survival. Actually, these patients present the same survival rate as patients similarly staged in whom portal vein resection was not performed. Therefore, venous resection is worthwhile. The authors describe an alternative technique for venous reconstruction after resection of a long segment of portal or superior mesenteric vein. The use of a venous graft as proposed in this study is feasible, easy to perform, and may simplify the venous reconstruction even in extensive mesentericoportal venous resection.

Animal bite is a rare but potentially severe cause of genital trauma and children are the most common victims. Morbidity is directly associated with the severity of the initial wound. Because patients tend to seek medical care promptly, infectious complications are unusual. Management involves irrigation, débridement, antibiotic prophylaxis, and tetanus and rabies immunization as appropriate as well as primary wound closure or surgical reconstruction. Good functional and cosmetic results are possible in the majority of cases.

In recipients of liver transplantation (LT), surgical site infection (SSIs) are among the most common types of infection occurring in the first 60 days after LT. In 2007, the Model for End-Stage Liver Disease (MELD) scoring system was adopted as the basis for prioritizing organ allocation. Patients with higher MELD scores are at higher risk for developing SSIs as well as other health care-associated infections. However, there have been no studies comparing the incidence of SSIs in the pre-MELD era with the incidence in the period since its adoption. Therefore, the objectives of this study were to evaluate the incidence, etiology, epidemiology, and outcomes of post-LT SSIs in those 2 periods and to identify risk factors for SSIs. We evaluated all patients who underwent LT over a 10-year period (2002)(2003)(2004)(2005)(2006)(2007)(2008)(2009)(2010)(2011). SSI cases were identified through active surveillance. The primary outcome measure was an SSI during the first 60 days after LT. Risk factors were analyzed via logistic regression, and 60-day survival rates were evaluated via Cox regression. We evaluated 543 patients who underwent LT 597 times. The SSI rates in the 2002-2006 and 2007-2011 periods were 30% and 24%, respectively (P 5 0.21). We identified the following risk factors for SSIs: retransplantation, the transfusion of more than 2 U of blood during LT, dialysis, cold ischemia for >400 minutes, and a cytomegalovirus infection. The overall 60-day survival rate was 79%. Risk factors for 60-day mortality were retransplantation, dialysis, and a longer surgical time. The use of the MELD score modified the incidence and epidemiology of SSIs only during the first year after its adoption. Risks for SSIs were related more to intraoperative conditions and intercurrences after LT than to a patient's status before LT.

-003. fgalvao@usp.br RESUMO OBJETIVOS. Analisar o conhecimento e a opinião de estudantes de medicina sobre doação e transplante de órgãos. MÉTODOS. Trezentos e quarenta e sete estudantes responderam, voluntariamente, questionário com 17 perguntas sobre doação e transplante de órgãos. Eles foram avaliados globalmente, para verificar tendências gerais, e agrupados de acordo com o seu ano no curso médico (primeiro ao sexto), para avaliar diferenças entre os períodos. Alunos do quinto e sexto ano foram reunidos em um só grupo. Os resultados foram analisados pelo teste Qui quadrado. RESULTADOS. A intenção de ser doador post mortem foi de 89% e intervivo de 90%, contudo, apenas 62% sabiam dos riscos da doação intervivo. Entre os 347 estudantes, 70% admitiram conhecimento regular, ruim ou péssimo do assunto, 90,2% consideraram importante o tema transplante para a graduação médica, 76,9% consideraram o consentimento informado/ expresso como o melhor critério de doação e 64,3% optaram pela gravidade da doença do paciente como melhor forma de alocação. O entendimento sobre transplante aumentou conforme o avanço no curso de graduação. Estudantes do quarto, quinto e sexto ano adotaram atitude negativa, em comparação aos dos anos iniciais, quanto à doação de órgãos para pacientes alcoólatras, não doadores, usuários de drogas ilícitas, estrangeiros e criminosos. CONCLUSÃO. Este trabalho demonstrou grande interesse e atitude positiva dos estudantes de medicina sobre doação e transplante de órgãos, embora a maioria tenha declarado conhecimento deficiente sobre o tema. Observamos também atitude negativa dos estudantes do quarto, quinto e sexto ano médico em relação à doação para alcoólatras, não doadores, usuários de drogas ilícitas, estrangeiros e criminosos. UNITERMOS: Doação de órgãos. Transplante. Estudantes de medicina. Conhecimentos. Atitudes. Ética. INTRODUÇÃOO transplante de órgãos no Brasil é atividade social, pois geralmente é custeado pelo sistema único de saúde (SUS) e depende da doação espontânea da população.Nos últimos anos, ocorreu aumento significativo no número de transplantes de órgãos em quase todos os estados da Federação, situando o Brasil entre os países que mais realizam transplante no mundo 1 . Contudo, a desinformação sobre temas básicos deste método terapêutico prejudica o seu desenvolvimento e provoca baixo índice de captação, má qualidade dos enxertos obtidos e interferência negativa nos resultados dos transplantes 1,2 . A educação médica é fator decisivo para o refinamento técnico do transplante e a melhora no índice de captação de órgãos 2-9 . A promoção de debates sobre transplante, envolvendo profissionais da saúde e sociedade em geral, é a melhor estratégia para aprimorar este procedimento e elevar sua discussão ética 2-5 . Existem na literatura médica evidências de conhecimento insuficiente dos médicos brasileiros sobre o tema transplante de órgãos, o que pode justificar o baixo nível de captação de órgãos em nosso meio 2,7,9 . Baseados nesta informação da literatura, presumimos que a desinform...

CONTEXT AND OBJECTIVE: Expanded donor criteria (marginal) grafts are an important solution for organ shortage. Nevertheless, they raise an ethical dilemma because they may increase the risk of transplant failure. This study compares the outcomes from marginal and non-marginal graft transplantation in 103 cases of liver transplantation due to chronic hepatic failure. DESIGN AND SETTING: One hundred and three consecutive liver transplantations to treat chronic liver disease performed in the Liver Transplantation Service of Hospital das Clínicas da Faculdade de Medicina da Universidade de São Paulo between January 2001 and March 2006 were retrospectively analyzed. METHODS: We estimated graft quality according to a validated scoring system. We assessed the pre-transplantation liver disease category using the Model for End-Stage Liver Disease (MELD), as low MELD (< 20) or high MELD (> 20). The parameters for marginal and non-marginal graft comparison were the one-week, one-month and one-year recipient survival rates, serum liver enzyme peak, post-transplantation hospital stay and incidence of surgical complications and retransplantation. The significance level was 0.05. RESULTS: There were no differences between the groups regarding post-transplantation hospital stay, serum liver enzyme levels and surgical complications. In contrast, marginal grafts decreased overall recipient survival one month after transplantation. Furthermore, low-MELD recipients of non-marginal grafts showed better one-week and one-month survival than did high-MELD recipients of marginal livers. After the first month, patient survival was comparable in all groups up to one year. CONCLUSION: The use of marginal graft increases early mortality in liver transplantation, particularly among high-MELD recipients.
