article 27 Citação(ões) na Scopus Impact of the severity of end-stage liver disease in cardiac structure and function(2013) SILVESTRE, Odilson Marcos; BACAL, Fernando; RAMOS, Danusa de Souza; ANDRADE, Jose L.; FURTADO, Meive; PUGLIESE, Vincenzo; BELLETI, Elisangela; ANDRAUS, Wellington; CARRILHO, Flair Jose; D'ALBUQUERQUE, Luiz Augusto Carneiro; FARIAS, Alberto QueirozBackground. The impact of end-stage liver disease (ESLD) in cardiac remodeling of patients with cirrhosis is unknown. Our aim was to correlate the severity of ESLD with morphologic and functional heart changes. Material and methods. 184 patients underwent a protocol providing data on the severity of ESLD and undergoing echocardiography to assess the diameters of the left atrium and right ventricle; the systolic and diastolic diameters of the left ventricle, interventricular septum, and posterior wall of the left ventricle; systolic pulmonary artery pressure; ejection fraction; and diastolic function. Severity of ESLD was assessed by the Model for End-Stage Liver Disease (MELD) score. Results. Left-atrial diameter (r = 0.323; IC 95% 0.190-0.455; p < 0.001), left-ventricular diastolic diameter (r = 0.177; IC 95% 0.033-0.320; p = 0.01) and systolic pulmonary artery pressure (r = 0.185; IC 95% 0.036-0.335; p = 0.02) significantly correlated with MELD score. Patients with MELD 16 had significantly higher left-atrial diameter and systolic pulmonary artery pressure, compared with patients with MELD scores < 16 points. Conclusions. Changes in cardiac structure and function correlate with the severity of ESLD.- Intentional use of Schistosoma mansoni-infected grafts in living donor liver transplantation(2012) ANDRAUS, Wellington; PUGLIESE, Vicenzo; PECORA, Rafael; D'ALBUQUERQUE, Luiz Augusto C.
- Liver transplantation: Fifty years of experience(2014) SONG, Alice Tung Wan; AVELINO-SILVA, Vivian Iida; PECORA, Rafael Antonio Arruda; PUGLIESE, Vincenzo; D'ALBUQUERQUE, Luiz Augusto Carneiro; ABDALA, EdsonSince 1963, when the first human liver transplantation (LT) was performed by Thomas Starzl, the world has witnessed 50 years of development in surgical techniques, immunosuppression, organ allocation, donor selection, and the indications and contraindications for LT. This has led to the mainstream, wellestablished procedure that has saved innumerable lives worldwide. Today, there are hundreds of liver transplant centres in over 80 countries. This review aims to describe the main aspects of LT regarding the progressive changes that have occurred over the years. We herein review historical aspects since the first experimental studies and the first attempts at human transplantation. We also provide an overview of immunosuppressive agents and their potential side effects, the evolution of the indications and contraindications of LT, the evolution of survival according to different time periods, and the evolution of methods of organ allocation.
- 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

- SURGICAL OUTCOMES AND PROGNOSTIC FACTORS IN PATIENTS WITH SYNCHRONOUS COLORECTAL LIVER METASTASES(2014) FONTANA, Rafael; HERMAN, Paulo; PUGLIESE, Vincenzo; PERINI, Marcos Vinicius; COELHO, Fabricio Ferreira; CECCONELLO, IvanContext Colorectal cancer is the second most prevalent cancer worldwide, and the liver is the most common site of metastases. Surgical resection of colorectal liver metastases provides the sole possibility of cure and the best odds of long-term survival. Objectives To describe surgical outcomes and identify features associated with disease prognosis in patients submitted to synchronous colorectal cancer liver metastasis resection. Methods Retrospective study of 59 patients who underwent surgery for synchronous colorectal cancer liver metastasis. Actuarial survival and disease-free survival were assessed, depending on the prognostic variable of interest. Results Postoperative mortality and morbidity rates were 3.38% and 30.50% respectively. Five-year disease-free survival was estimated at 23.96%, and 5-year overall survival, at 38.45%. Carcinoembryonic antigen levels ≥50 ng/mL and presence of three or more liver metastasis were limiting factors for disease-free survival, but did not affect late survival. No patient with liver metastases and extrahepatic disease had disease-free interval longer than 20 months, but this had no significance or impact on long-term survival. None of the prognostic factors assessed had an impact on late survival, although no patients with more than three liver metastases survived beyond 40 months. Conclusions Although Carcinoembryonic antigen levels and number of metastases are prognostic factors that limit disease-free survival, they had no impact on 5-year survival and, therefore, should not determine exclusion from surgical treatment. Resection is the best treatment option for synchronous colorectal liver metastases, and even for patients with multiple metastases, large tumors and extrahepatic disease, it can provide long-term survival rates over 38%.
- 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.
- Serum B-Type Natriuretic Peptide in the Initial Workup of Patients With New Onset Ascites: A Diagnostic Accuracy Study(2014) FARIAS, Alberto Q.; SILVESTRE, Odilson M.; GARCIA-TSAO, Guadalupe; SEGURO, Luis F. B. da Costa; MAZO, Daniel F. de Campos; BACAL, Fernando; ANDRADE, Jose L.; GONCALVES, Luciana L.; STRUNZ, Celia; RAMOS, Danusa S.; POLLI, Demerson; PUGLIESE, Vincenzo; RODRIGUES, Ana C. T.; FURTADO, Meive S.; CARRILHO, Flair J.; D'ALBUQUERQUE, Luiz A. C.Heart failure (HF) is, after cirrhosis, the second-most common cause of ascites. Serum B-type natriuretic peptide (BNP) plays an important role in the diagnosis of HF. Therefore, we hypothesized that BNP would be useful in the differential diagnosis of ascites. Consecutive patients with new onset ascites were prospectively enrolled in this cross-sectional study. All patients had measurements of serum-ascites albumin gradient (SAAG), total protein concentration in ascitic fluid, serum, and ascites BNP. We enrolled 218 consecutive patients with ascites resulting from HF (n = 44), cirrhosis (n = 162), peritoneal disease (n = 10), and constrictive pericarditis (n = 2). Compared to SAAG and/or total protein concentration in ascites, the test that best discriminated HF-related ascites from other causes of ascites was serum BNP. A cutoff of >364 pg/mL (sensitivity 98%, specificity 99%, and diagnostic accuracy 99%) had the highest positive likelihood ratio (168.1); that is, it was the best to rule in HF-related ascites. Conversely, a cutoff 182 pg/mL had the lowest negative likelihood ratio (0.0) and was the best to rule out HF-related ascites. These findings were confirmed in a 60-patient validation cohort. Conclusions: Serum BNP is more accurate than ascites analyses in the diagnosis of HF-related ascites. The workup of patients with new onset ascites could be streamlined by obtaining serum BNP as an initial test and could forego the need for diagnostic paracentesis, particularly in cases where the cause of ascites is uncertain and/or could be the result of HF.
