- Dimensão da margem cirúrgica nas ressecções de metástase hepática de câncer colorretal: impacto na recidiva e sobrevida(2013) HERMAN, Paulo; PINHEIRO, Rafael S.; MELLO, Evandro S.; LAI, Quirino; LUPINACCI, Renato M.; PERINI, Marcos V.; PUGLIESE, Vincenzo; ANDRAUS, Wellington; COELHO, Fabricio F.; CECCONELLO, Ivan; D'ALBUQUERQUE, Luiz C.BACKGROUND: Approximately 50% of the patients with a colorectal tumor develop liver metastasis, for which hepatectomy is the standard care. Several prognostic factors have been discussed, among which is the surgical margin. This is a recurring issue, since no consensus exists as to the minimum required distance between the metastatic nodule and the liver transection line. AIM: To evaluate the surgical margins in liver resections for colorectal metastases and their correlation with local recurrence and survival. METHODS: A retrospective study based on the review of the medical records of 91 patients who underwent resection of liver metastases of colorectal cancer. A histopathological review was performed of all the cases; the smallest surgical margin was verified, and the late outcome of recurrence and survival was evaluated. RESULTS: No statistical difference was found in recurrence rates and overall survival between the patients with negative or positive margins (R0 versus R1); likewise, there was no statistical difference between subcentimeter margins and those greater than 1 cm. The disease-free survival of the patients with microscopically positive margins was significantly worse than that of the patients with negative margins. The uni- and multivariate analyses did not establish the surgical margin (R1, narrow or less than 1 cm) as a risk factor for recurrence. CONCLUSION: The resections of liver metastases with negative margins, independently of the margin width, had no impact on tumor recurrence (intra- or extrahepatic) or patient survival
- Trombose de veia porta no transplante hepático(2012) PÉCORA, Rafael Antonio Arruda; CANEDO, Bernardo Fernandes; ANDRAUS, Wellington; MARTINO, Rodrigo Bronze de; SANTOS, Vinicius Rocha; ARANTES, Rubens Macedo; PUGLIESE, Vincenzo; D´ALBUQUERQUE, Luiz Augusto CarneiroBACKGROUND: Portal vein thrombosis was considered a contraindication for liver transplantation in the past because of the high morbidity and mortality rates. Many advances made the results better. AIM: Review the advances and surgical strategies for liver transplantation in presence of portal vein thrombosis. METHOD: Survey of publications in Medline, Scielo and Lilacs databases. Headings crossed: portal vein thrombosis, liver transplantation, vascular complications, jump graft, graft failure, multivisceral transplant. Data analyzed were epidemiology, risk factors, classification, diagnosis, surgical strategies and outcomes. CONCLUSION: Portal vein thrombosis is not a contraindication for liver transplantation anymore. There are many strategies to perform the liver transplantation in this condition, depending on portal vein thrombosis grade. Regardless higher morbidity and re-trhombosis rates, the outcomes of liver transplantation in portal vein thrombosis are similar to series without portal vein thrombosis.
