- Insights of Outcome after Resection of Small Nonfunctioning Neuroendocrine Pancreatic Tumors(2021) FIGUEIRA, Estela Regina Ramos; RIBEIRO, Julia Fray; RIBEIRO, Thiago Costa; JUREIDINI, Ricardo; NAMUR, Guilherme Naccache; COSTA, Thiago Nogueira; BACCHELLA, Telesforo; CECCONELLO, IvanBackground. The incidence of small nonfunctioning neuroendocrine pancreatic tumors (NF-PNETs) has been increasing systematically in the last few decades. Surgical resection was once considered the treatment of choice but has been questioned in the direction of a more conservative approach for selected patients. Our aim was to analyze the outcome of surgical resection of small (<= 3cm) NF-PNETs. Methods. We retrospectively evaluated 14 patients with sporadic NF-PNETs who underwent pancreatic resection. Data were collected from patients' medical records. Results. Of the 14 patients included, 35.71% were men, and the average age was 52.36 +/- 20.36 years. Comorbidities were present in 92.86% of the cases. The incidence of postoperative complications was 42.86%, the 30-day mortality was zero, and the length of follow-up was 3.31 +/- 3.0 years. The results of pathological evaluations revealed WHO grade I in 42.86% of cases, II in 21.43%, and neuroendocrine carcinoma in 35.71%. The median tumor size was 1.85cm (range, 0.5-3cm), and 2 cases had synchronous metastasis. The median TNM stage was IIa (range, I-IV). The disease-free and patient survival rates were 87.5% and 100% at 3 years and 43.75% and 75% at 10 years, respectively. The tumor pathological grade was significantly higher in head tumors than body-tail tumors, but there were no differences with respect to tumor size and TNM staging. Conclusion. A surgical approach to treat small sporadic NF-PNETs is safe with low mortality and high patient survival. Based on these data, small pancreatic head tumors can be more aggressive, suggesting that surgical resection is still the best option to treat small nonfunctioning PNETS. Thus, conservative treatment should be indicated very cautiously for only cases with absolute contraindications for surgery.
- Evaluation of drug-induced liver injury as etiology for acute liver failure in Brazil(2021) SANTOS, Genario; FIGUEIRA, Estela Regina Ramos; D'ALBUQUERQUE, Luiz Augusto Carneiro; LISBOA, Paulo Bittencourt; ALMEIDA, Marcio Dias de; FILGUEIRA, Norma Arteiro; BOIN, Ilka; PORTA, Gilda; SILVA, Rita de Cassia Martins Alves da; VIANA, Cyntia Ferreira Gomes; FARIA, Luciana Costa; ALVARES-DA-SILVA, Mario Reis; MORAES, Adriano Claudio Pereira de; MORSOLETTO, Daphne Benatti Goncalves; CODES, Liana; PARANA, RaymundoIntroduction and objectives: Little is known about the etiology of acute liver failure (ALF) in Latin America. The objective of this paper is to investigate the main etiologies of ALF in Brazil, including Drug Induced Liver Injury (DILI) using stringent causality criteria. Patients or material and methods: All the cases of individuals who underwent liver transplantation (LT) in 12 centers in Brazil for ALF were reviewed. When DILI was stated as the cause of ALF, causality criteria were applied on site by the main investigator in order to rule out other etiologies. Results: 325 individuals had ALF mainly for unknown reasons (34%), DILI (27%) and AIH (18%). Reassessment of the 89 cases of DILI, using stringent causality criteria, revealed that in only 42 subjects could DILI be confirmed as the cause of ALF. Acetaminophen (APAP) toxicity (n = 3) or DILI due to herbal and dietary supplements (HDS) (n = 2) were not commonly observed. Conclusions: Undetermined etiology and DILI are the main causes of ALF in Brazil. However, APAP toxicity and DILI due to HDS are mostly uncommon.

In this setting, hypothermia is the gold standard method for liver preservation for trans-plantation. Hypertonic saline solution reduces inflammatory response with better hemodynamic recovery in several situations involving ischemia reperfusion injury. Here, we investigated the effect of hypertonic saline solution in hypothermic liver submitted to ischemia reperfusion injury. Methods: Fifty male rats were divided into 5 groups: SHAM, WI (animals submitted to 40 minutes of partial warm liver ischemia and reperfusion), HI (animals submitted to 40 minutes hypothermic ischemia), HSPI (animals submitted to hypothermic ischemia and treated with 7.5% hypertonic saline solution preischemia), and HSPR (animals submitted to hypothermic ischemia and treated with hypertonic saline solution previously to liver reperfusion). Four hours after reperfusion, the animals were euthanized to collect liver and blood samples. Results: Aspartate aminotransferase and alanine aminotransferase, histologic score, and hepatocellular necrosis were significantly decreased in animals submitted to hypothermia compared with the warm ischemia group. Malondialdehyde was significantly decreased in hypothermic groups with a further decrease when hypertonic saline solution was administrated preischemia. Hypothermic groups also showed decreased interleukin-6, interleukin-10, and tumor necrosis factor-alpha concentrations and better recovery of bicarbonate, base excess, lactate, and glucose blood concentrations. Moreover, hypertonic saline solution preischemia was more effective at controlling serum potassium concentrations. Conclusion: Hypertonic saline solution before hypothermic hepatic ischemia decreases hepatocellular oxidative stress, cytokine concentrations, and promotes better recovery of acid-base disorders secondary to liver ischemia reperfusion.
- Perioperative blood transfusion decreases long-term survival in pediatric living donor liver transplantation(2021) GORDON, Karina; FIGUEIRA, Estela Regina Ramos; ROCHA-FILHO, Joel Avancini; MONDADORI, Luiz Antonio; JOAQUIM, Eduardo Henrique Giroud; SEDA-NETO, Joao; FONSECA, Eduardo Antunes da; PUGLIESE, Renata Pereira Sustovitch; VINTIMILLA, Agustin Moscoso; JR, Jose Otavio Costa Auler; CARMONA, Maria Jose Carvalho; D'ALBURQUERQUE, Luiz Augusto CarneiroBACKGROUND The impact of perioperative blood transfusion on short- and long-term outcomes in pediatric living donor liver transplantation (PLDLT) must still be ascertained, mainly among young children. Clinical and surgical postoperative complications related to perioperative blood transfusion are well described up to three months after adult liver transplantation. AIM To determine whether transfusion is associated with early and late postoperative complications and mortality in small patients undergoing PLDLT. METHODS We evaluated the effects of perioperative transfusion on postoperative complications in recipients up to 20 kg of body weight, submitted to PLDLT. A total of 240 patients were retrospectively allocated into two groups according to postoperative complications: Minor complications (n = 109) and major complications (n = 131). Multiple logistic regression analysis identified the volume of perioperative packed red blood cells (RBC) transfusion as the only independent risk factor for major postoperative complications. The receiver operating characteristic curve was drawn to identify the optimal volume of the perioperative RBC transfusion related to the presence of major postoperative complications, defining a cutoff point of 27.5 mL/kg. Subsequently, patients were reallocated to a low-volume transfusion group (LTr; n = 103, RBC <= 27.5 mL/kg) and a high-volume transfusion group (HTr; n = 137, RBC > 27.5 mL/kg) so that the outcome could be analyzed. RESULTS High-volume transfusion was associated with an increased number of major complications and mortality during hospitalization up to a 10-year follow-up period. During a short-term period, the HTr showed an increase in major infectious, cardiovascular, respiratory, and bleeding complications, with a decrease in rejection complications compared to the LTr. Over a long-term period, the HTr showed an increase in major infectious, cardiovascular, respiratory, and minor neoplastic complications, with a decrease in rejection complications. Additionally, Cox hazard regression found that high-volume RBC transfusion increased the mortality risk by 3.031-fold compared to low-volume transfusion. The Kaplan-Meier survival curves of the studied groups were compared using log-rank tests and the analysis showed significantly decreased graft survival, but with no impact in patient survival related to major complications. On the other hand, there was a significant decrease in both graft and patient survival, with high-volume RBC transfusion. CONCLUSION Transfusion of RBC volume higher than 27.5 mL/kg during the perioperative period is associated with a significant increase in short- and long-term postoperative morbidity and mortality after PLDLT.
- Laparoscopic SpyGlass cholangioscopy evaluation during bilioenteric anastomosis for hepatolithiasis, a case report(2021) FIGUEIRA, Estela Regina Ramos; FRANZINI, Tomazo; COSTA, Thiago Nogueira; MADRUGA-NETO, Antonio Coutinho; GUEDES, Hugo Goncalo; ROMANO, Vitor Carminatti; CECONELLO, Ivan; MOURA, Eduardo Guimaraes Hourneaux deINTRODUCTION: Careful evaluation of intrahepatic injury of biliary tract diseases is crucial to assure proper management and estimate disease prognosis. Hepatholithiasis is a rare condition that can be associated to cholestatic liver diseases. Additional tools to improve diagnosis and patient care are of great interest specially if associated to decreased morbidity. Recently the spread of single-operator platforms of cholangioscopy brought this procedure back to scene. Our aim was to identify safety, feasibility and utility of SpyGlass cholangioscopy of biliary tract during laparoscopic hepaticojejunostomy. PRESENTATION OF CASE: A 53 years-old man with hepatolithiasis associated to choledolithiasis under treatment with ursodeoxycholic acid and fenofibrate for 8 months, was submitted to laparoscopic hepaticojejunostomy with cholangioscopy for biliary duct evaluation. Spyscope was inserted through a right lateral laparoscopic trocar entering the common bile duct. Examination of intra-hepatic bile ducts showed injury of right biliary. Few microcalculi were visualized. Left biliary ducts presented normal mucosa. Histopathological examination showed a chronic inflammatory process. During the procedure contrasted radiologic images were performed to assure Spyscope location. Following cholangioscopy evaluation, a Roux-en-Y hepaticojejunostomy was performed. To enlarge hepatic duct, a small longitudinal incision was made, and a PDS-5.0 running suture was used for bilioenteric anastomosis. Patient was discharged on postoperative day 6, with drain removal on day 20. CONCLUSION: SpyGlass cholangioscopy during laparoscopic hepaticojejunostomy is feasible leading to minimal additional invasion of the surgical. In this case the method was performed safely, providing detailed examination of injured biliary ducts, adding elements to determine disease prognosis and patient care. (C) 2020 The Authors.
bookPart Monitorização do Sistema Hematológico(2021) ROCHA FILHO, Joel Avancini; FIGUEIRA, Estela Regina Ramos- Creatinine-lactate score predicts mortality in non-acetaminophen-induced acute liver failure in patients listed for liver transplantation(2021) FIGUEIRA, Estela Regina Ramos; ROCHA-FILHO, Joel Avancini; LANCHOTTE, Cinthia; NACIF, Lucas Souto; HADDAD, Luciana Bertocco de Paiva; ASSALIN, Adriana Rochetto; SHINKADO, Yumi Ricucci; VINTIMILLA, Agustin Moscoso; GALVAO, Flavio Henrique Ferreira; D'ALBUQUERQUE, Luiz Augusto CarneiroBackground The aim of this study was to analyze prognostic indicators of in-hospital mortality among patients listed for urgent liver transplantation (LT) for non-acetaminophen (APAP)-induced acute liver failure (ALF). Methods ALF patients listed for LT according to the King's College Criteria were retrospectively reviewed. Variables were recorded from medical records and electronic databases (HCMED and RedCap). Results The study included 100 patients, of which 69 were subject to LT and 31 died while waiting for LT. Patients were 35.5 +/- 14.73 years old, and 78% were females. The main etiologies were virus (17%), drug-induced (32%), autoimmune (15%), and indeterminate hepatitis (31%). The prioritization-to-LT time interval was 1.5 days (0-9). The non-LT patients showed higher lactate (8.71 +/- 5.36 vs. 4.48 +/- 3.33 mmol/L), creatinine (229 +/- 207 vs. 137 +/- 136 mu m/L), MELD (44 +/- 8 vs. 38 +/- 8), and BiLE scores (15.8 +/- 5.5 vs. 10.3 +/- 4.1) compared to LT patients (p < 0.05). Multiple logistic regression analysis identified creatinine and lactate as independent prognostic factors, and a creatinine-lactate (CL) score was developed. ROC analysis showed that creatinine, lactate, MELD, BiLE, and CL scores had considerable specificity (71-88%), but only BiLE, lactate, and CL presented high sensitivities (70%, 80%, and 87% respectively). AUCs were 0.696 for creatinine, 0.763 for lactate, 0.697 for MELD, 0.814 for BiLE, and 0.835 for CL. Conclusions CL and BiLE scores predict mortality with more accuracy than MELD in patients with ALF during prioritization time. Creatinine and lactate are independent prognostic factors for mortality.
