RESUMO

INTRODUCTION: Hepatectomies associated with vascular resections pose a technical challenge for surgeons, involving multiple reconstruction techniques. Moreover, adding clinical and surgical risks in the postoperative setting of these complex procedures are mainly due to prolonged surgical periods and potential complications inherent to vascular manipulation. Leveraging the expertise of a Cancer Center, we propose an institutional assessment utilizing the case series from A. C. Camargo Cancer Center in hepatectomies associated with vascular resection, evaluating postoperative complications and outcomes while highlighting clinical, laboratory, pathological, and surgical factors that may influence results. OBJECTIVE: To assess mortality and morbidity associated with hepatectomies involving vascular resection. MATERIALS AND METHODS: From a prospective database, a study was performed evaluating postoperative survival and morbidity using scoring systems such as Clavien-Dindo through a cohort analysis. RESULTS: From a total of 1021 liver resections for a period of 10 years, 31 cases were evaluated from a unique cancer center in Brazil! Factors such as the performance of major hepatectomies, the need for blood transfusion, and the administration of neoadjuvant or adjuvant systemic therapy did not appear to influence the outcome of morbidity or mortality. However, the resection of the associated bile duct and the type of vascular resection seemed to influence morbidity outcomes with statistical significance (p = 0.006+ …). CONCLUSION: Hepatectomies associated with vascular resections are safe in selected cases and when performed in referral centers. Factors such as associated bile duct resection and type of vascular resection should be considered for procedure indication.

RESUMO

BACKGROUND: Incidental gallbladder cancer is defined as a cancer discovered by histological examination after cholecystectomy. It is a potentially curable disease. However, some questions related to their management remain controversial and a defined strategy is associated with better prognosis. AIM: To develop the first evidence-based consensus for management of patients with incidental gallbladder cancer in Brazil. METHODS: Sixteen questions were selected, and 36 Brazilian and International members were included to the answer them. The statements were based on current evident literature. The final report was sent to the members of the panel for agreement assessment. RESULTS: Intraoperative evaluation of the specimen, use of retrieval bags and routine histopathology is recommended. Complete preoperative evaluation is necessary and the reoperation should be performed once final staging is available. Evaluation of the cystic duct margin and routine 16b1 lymph node biopsy is recommended. Chemotherapy should be considered and chemoradiation therapy if microscopically positive surgical margins. Port site should be resected exceptionally. Staging laparoscopy before reoperation is recommended, but minimally invasive radical approach only in specialized minimally invasive hepatopancreatobiliary centers. The extent of liver resection is acceptable if R0 resection is achieved. Standard lymph node dissection is required for T2 tumors and above, but common bile duct resection is not recommended routinely. CONCLUSIONS: It was possible to prepare safe recommendations as guidance for incidental gallbladder carcinoma, addressing the most frequent topics of everyday work of digestive and general surgeons.

RESUMO Racional: Carcinoma incidental da vesícula biliar é definido como uma neoplasia descoberta por exame histológico após colecistectomia videolaparoscópica. É potencialmente uma doença curável. Entretanto algumas questões relacionadas ao seu manuseio permanecem controversas e uma estratégia definida está associada com melhor prognóstico. Objetivo: Desenvolver o primeiro consenso baseado em evidências para o manuseio de pacientes com carcinoma incidental da vesícula biliar no Brasil. Métodos: Dezesseis questões foram selecionadas e para responder as questões e 36 membros das sociedades brasileiras e internacionais foram incluídos. As recomendações foram baseadas em evidências da literatura atual. Um relatório final foi enviado para os membros do painel para avaliação de concordância. Resultados: Avaliação intraoperatória da peça cirúrgica, uso de bolsas para retirar a peça cirúrgica e exame histopatológico de rotina, foram recomendados. Avaliação pré-operatória completa é necessária e deve ser realizada assim que o estadiamento final esteja disponível. Avaliação da margem do ducto cístico e biópsia de rotina do linfonodo 16b1 são recomendadas. Quimioterapia deve ser considerada e quimioradioterapia indicada se a margem cirúrgica microscópica seja positiva. Os portais devem ser ressecados excepcionalmente. O estadiamento laparoscópico antes da operação é recomendado, mas o tratamento radical por abordagem minimamente invasiva deve ser realizado apenas em centros especializados em cirurgia hepatopancreatobiliar minimamente invasiva. A extensão da ressecção hepática é aceitável até que seja alcançada a ressecção R0. A linfadenectomia padrão é indicada para tumores iguais ou superiores a T2, mas a ressecção da via biliar não é recomendada de rotina. Conclusões: Recomendações seguras foram preparadas para carcinoma incidental da vesícula biliar, destacando os mais frequentes tópicos do trabalho diário do cirurgião do aparelho digestivo e hepatopancreatobiliar.
