Classification of Intrahepatic Cholangiocarcinoma into Perihilar Versus Periphe...
Wei, T; Lu, J; Xiao, XL; Weiss, M; Popescu, I; Pinto Marques, H; Aldrighetti, L; Maithel, SK; Pulitano, C; Bauer, TW; Shen, F; Poultsides, GABackground: Intrahepatic cholangiocarcinoma (ICC) constitutes a group of heterogeneous malignancies within the liver. We sought to subtype ICC based on anatomical origin of tumors, as well as propose modifications of the current classification system. Methods: Patients undergoing curative-intent resection for ICC, hilar cholangiocarcinoma (CCA), or hepatocellular carcinoma (HCC) were identified from three inter...
TAC Score Better Predicts Survival Than the BCLC Following Resection of Hepatoc...
Lima, H; Endo, Y; Moazzam, Z; Alaimo, L; Shaikh, C; Munir, M; Resende, V; Guglielmi, A; Pinto Marques, H; Cauchy, F; Lam, V; Poultsides, G; Popescu, IBackground: Heterogeneity in hepatocellular carcinoma (HCC) still exists within the Barcelona clinic liver cancer (BCLC) subcategories. We developed a simple model to better discriminate and predict prognosis following resection. Methods: Patients who underwent curative-intent resection for HCC were identified from a multi-institutional database. Predictive factors of survival were identified to develop TAC (tu...
An Attempt to Establish and Apply Global Benchmarks for Liver Resection of Mali...
Alaimo, L; Moazzam, Z; Lima, H; Endo, Y; Ruzzenente, A; Guglielmi, A; Ratti, F; Aldrighetti, L; Weiss, M; Bauer, T; Alexandrescu, S; Popescu, IBackground: Benchmarking is a process of continuous self-evaluation and comparison with best-in-class hospitals to guide quality improvement initiatives. We sought to define global benchmarks relative to liver resection for malignancy and to assess their achievement in hospitals in the United States. Methods: Patients who underwent curative-intent liver resection for hepatocellular carcinoma, intrahepatic chola...
Pancreas Rejection in the Artificial Intelligence Era: New Tool for Signal Pati...
Vigia, E; Ramalhete, L; Ribeiro, R; Barros, I; Chumbinho, B; Filipe, E; Pena, A; Bicho, L; Nobre, A; Carrelha, S; Sobral, M; Lamelas, J; Coelho, JSIntroduction: Pancreas transplantation is currently the only treatment that can re-establish normal endocrine pancreatic function. Despite all efforts, pancreas allograft survival and rejection remain major clinical problems. The purpose of this study was to identify features that could signal patients at risk of pancreas allograft rejection. Methods: We collected 74 features from 79 patients who underwent simu...
A Novel Online Calculator to Predict Risk of Microvascular Invasion in the Preo...
Endo, Y; Alaimo, L; Lima, H; Moazzam, Z; Ratti, F; Pinto Marques, H; Soubrane, O; Lam, V; Kitago, M; Poultsides, G; Popescu, I; Alexandrescu, SBackground: The presence of microvascular invasion (MVI) has been highlighted as an important determinant of hepatocellular carcinoma (HCC) prognosis. We sought to build and validate a novel model to predict MVI in the preoperative setting. Methods: Patients who underwent curative-intent surgery for HCC between 2000 and 2020 were identified using a multi-institutional database. Preoperative predictive models fo...
Delayed Presentation of Isolated Grade III Pancreatic Injury - a Case Report
Ferreira, MJ; Gallardo, G; Vigia, E; Filipe, E; Pinto Marques, HBecause of their vague and subtle indications and symptoms, pancreatic injuries are frequently misdiagnosed. It's crucial to have a high level of clinical suspicion. The presence of other organ solid lesions and vascular injuries, as well as the patient's hemodynamic condition, will determine how these injuries are treated. A surgical approach is mandatory when a ductal disruption occurs. The case of a 32-year-...
The Impact of Donor Risk Index, Recipients’ and Operative Characteristics on Po...
Cardoso, FS; Bagulho, L; Coelho, JS; Lamelas, J; Mateus, E; Mendes, M; Glória, H; Ribeiro, V; Mega, R; Pena, A; Pinto Marques, H; Germano, N; Nolasco, FBackground and Aims: The donor risk index (DRI) quantifies donor-related characteristics potentially associated with increased risk of early graft failure. We aimed to assess the impact of the DRI, recipient and perioperative factors on post liver transplant (LT) outcomes. Methods: This was a singlecenter retrospective cohort study including all adult (≥18 years) patients who underwent LT from 01/2019 to 12/201...
Alcohol Consumption Post-Liver Transplantation: a Cross-Sectional Study
Chálim Rebelo, C; Félix, C; Sousa Cardoso, F; Bagulho, L; Sousa, M; Mendes, M; Glória, H; Mateus, É; Mega, I; Jara, M; Pinto Marques, H; Nolasco, FBackground: Listing patients with alcohol-associated liver disease (ALD) for liver transplant (LT) remains challenging especially due to the risk of alcohol resumption post-LT. We aimed to evaluate post-LT alcohol consumption at a Portuguese transplant center. Methods: We conducted a cross-sectional study including LT recipients from 2019 at Curry Cabral Hospital, Lisbon, Portugal. A pretested survey and a vali...
Application of Hazard Functions to Investigate Recurrence After Curative-Intent...
Lima, H; Alaimo, L; Brown, Z; Endo, Y; Moazzam, Z; Tsilimigras, D; Shaikh, C; Resende, V; Guglielmi, A; Ratti, F; Aldrighetti, L; Pinto Marques, HBackground: Defining patterns and risk of recurrence can help inform surveillance strategies and patient counselling. We sought to characterize peak hazard rates (pHR) and peak time of recurrence among patients who underwent resection of hepatocellular carcinoma (HCC). Methods: 1434 patients who underwent curative-intent resection of HCC were identified from a multi-institutional database. Hazard, patterns, and...
Predicting Function Delay with a Machine Learning Model: Improve the Long-term ...
Vigia, E; Ramalhete, L; Barros, I; Chumbinho, B; Filipe, E; Pena, A; Bicho, L; Nobre, A; Carrelha, S; Corado, S; Sobral, M; Lamelas, J; Santos Coelho, JThe impact of delayed graft function on outcomes following various solid organ transplants is well documented and addressed in the literature. Delayed graft function following various solid organ transplants is associated with both short- and long-term graft survival issues. In a retrospective cohort study including 106 patients we evaluated whether pancreas graft survival differs according to moment of insulin...
