    High versus low mean arterial pressure target in liver transplant patients. An open, controlled, single-center, randomized clinical trial - Protocol and methods (LIVER-PAM)
    (2023) PEDRO, Rodolpho Augusto de Moura; SCHARRANCH, Bruna Carla; ARAÚJO, Lucas de Oliveira; BRANDÃO, Luciana Severo; ANDRADE, Lúcia da Conceição; ANDRAUS, Wellington; D’ALBUQUERQUE, Luís Augusto Carneiro; MALBOUISSON, Luíz Marcelo Sá
    ABSTRACT Objective: To explain the rationale and protocol of the methods and analyses to be used in the LIVER-PAM randomized clinical trial, which seeks to understand whether a higher mean arterial pressure is capable of reducing the incidence of renal dysfunction postoperatively after liver transplantation. Methods: LIVER-PAM is an open-label, randomized, controlled, singlecenter clinical trial. Patients randomized to the intervention group will have a mean arterial pressure of 85 - 90mmHg in the initial 24 hours of postoperative management, while patients in the control group will have a mean arterial pressure of 65 - 70mmHg in the same period. A sample of 174 patients will be required to demonstrate a 20% reduction in the absolute incidence of renal dysfunction, with a power of 80% and an alpha of 0.05. Conclusion: If a 20% reduction in the absolute incidence of renal dysfunction in the postoperative period of liver transplantation is achieved with higher target mean arterial pressure in the first 24 hours, this would represent an inexpensive and simple therapy for improving current outcomes in the management of liver transplant patients.

    Innovative Technique Avoiding Bleeding After Reperfusion in Living Donor Liver Transplant Using a Modified Right Lobe Graft
    (2022) PINHEIRO, Rafael S.; ANDRAUS, Wellington; FORTUNATO, Allana C.; FERNANDES, Michel Ribeiro; NACIF, Lucas Souto; MARTINO, Rodrigo Bronze De; DUCATTI, Liliana; WAISBERG, Daniel Reis; ARANTES, Rubens Macedo; ROCHA-SANTOS, Vinicius; GALVAO, Flavio Henrique Ferreira; CARNEIRO-D'ALBUQUERQUE, Luiz Augusto
    Background. Living donor liver transplant (LDLT) is a valuable therapeutic option for over-coming the deceased donor shortage. Modified right lobe graft (MRLG) keeps the middle hepatic vein (MHV) trunk with the remnant liver to improve donor safety. Hemostasis in the MHV tributary reconstruction can be tricky; surgical stitches and energy coagulation are ineffective. Fibrin glues are excellent vascular sealants but are poor in maintaining hemostasis in an active hemorrhage or preventing resection surface-related complications after liver resection. We propose applying fibrin sealant during back table graft preparation to seal the hepatic edge and MHV reconstruction to avoid bleeding after graft revascularization. Methods. Our retrospective cohort study included all adult patients undergoing LDLT between August 2017 and December 2021. During the back table procedure, we performed the reconstruction of the inferior right hepatic vein and/or MHV tributaries from segment 5 (V5) and segment 8 (V8) using a vein harvested from a nonrelated deceased donor. Before initiating the hepatic graft implantation, we applied fibrin sealant in the resected parenchyma, especially in the V5 and V8 anastomosis, to seal the hepatic edge and hepatic vein reconstruction. Results. No bleeding was identified in the hepatic edge, and blood product transfusion was unnecessary for any recipients after reperfusion. Conclusion. In LDLT using MRLG with MHV reconstruction, the fibrin sealant, when applied on the raw hepatic surface, and vascular reconstruction during back table graft preparation avoided bleeding after graft revascularization.

    Consensus, Dilemmas, and Challenges in Living Donor Liver Transplantation in Latin America
    (2016) SALVALAGGIO, Paolo R.; NETO, Joao Seda; ALVES, Jefferson Andre; FONSECA, Eduardo A.; ALBUQUERQUE, Luiz Carneiro de; ANDRAUS, Wellington; MASSAROLLO, Paulo B.; GARCIA, Valter Duro; MAURETTE, Rafael J.; RUF, Andres E.; PACHECO-MOREIRA, Lucio F.; RUSCA, Luis A. Caicedo; OSORIO, Veronica Botero; MATAMOROS, Maria Amalia; VARELA-FASCINETTO, Gustavo; JARUFE, Nicolas P.
    We reviewed the history, volume, outcomes, uniqueness, and challenges of living donor liver transplantation (LDLT) in Latin America. We used the data from the Latin American and Caribbean Transplant Society, local transplant societies, and opinions from local transplant experts. There are more than 160 active liver transplant teams in Latin America, but only 30 centers have used LDLT in the past 2 years. In 2014, 226 LDLTs were done in the region (8.5% of liver transplant activities). Living donor liver transplantation is mainly restricted to pediatric patients. Adult-to-adult LDLT activities decreased after the implementation of the model for end-stage liver disease score and a concomitant increase on the rate of deceased donors per million population. Posttransplant outcome analysis is notmandatory, transparent or regulated in most countries. More experienced teams have outcomes comparable to international expert centers, but donor and recipient morbidity might be underreported. Latin America lags behind in terms of the number of adult LDLT and the rate of living donor utilization in comparison with other continents with similar donation rates. Local alliances and collaborations with major transplant centers in the developed world will contribute to the development of LDLT in Latin America.

    Laparoscopically excised retroperitoneal presacral Schwannoma: atypical pre and postoperative manifestations - case report
    (2019) CARVALHO, Barbara Justo; MEDEIROS, Kayo Augusto de Almeida; MARTINES, Diego Ramos; NII, Fernanda; PIPEK, Leonardo Zumerkorn; MESQUITA, Gustavo Heluani Antunes de; D'ALBUQUERQUE, Luiz Augusto Carneiro; MEYER, Alberto; ANDRAUS, Wellington
    Background We are a reporting a rare case of retroperitoneal schwanomma with atypical pre and postoperative manifestations. Retroperitoneal schwannomas are rare tumors that are difficult to preoperatively diagnose. Case presentation This is a case report of a male patient, 41 years old, with symptoms of hipogastric and lower right member pain, as well as a history of a papilliferous thyroid tumor. Computerized tomography exams were inconclusive, showing a mass in the presacral region with dimensions of 4.4 x 3.9 x 3.4 cm. Removal was carried out by laparoscopic surgery, with self-limited postoperative complications. Diagnosis was carried out by anatomopathological examination, and syndromic hypotheses were discarded. Conclusions The postoperative complications of schwanomma are little reported in the literature. In the simultaneous occurrence of schwanomma and other endocrine tumors, further studies are warranted to better differentiate the cases that need investigation of syndromic causes.

    The impact of properly diagnosed sarcopenia on postoperative outcomes after gastrointestinal surgery: A systematic review and meta-analysis
    (2020) PIPEK, Leonardo Zumerkorn; BAPTISTA, Carlos Guilherme; NASCIMENTO, Rafaela Farias Vidigal; TABA, Joao Victor; SUZUKI, Milena Oliveira; NASCIMENTO, Fernanda Sayuri do; MARTINES, Diego Ramos; NII, Fernanda; IUAMOTO, Leandro Ryuchi; CARNEIRO-D'ALBUQUERQUE, Luiz Augusto; MEYER, Alberto; ANDRAUS, Wellington
    Background Sarcopenia is defined as the loss of muscle mass combined with loss of muscle strength, with or without loss of muscle performance. The use of this parameter as a risk factor for complications after surgery is not currently used. This meta-analysis aims to assess the impact of sarcopenia defined by radiologically and clinically criteria and its relationship with complications after gastrointestinal surgeries. Materials and methods A review of the literature was conducted in accordance with the Preferred Reporting Items for Systematic Reviews and Meta-Analyses (PRISMA) guidelines (PROSPERO registration number: CRD42019132221). Articles were selected from the PUBMED and EMBASE databases that adequately assessed sarcopenia and its impact on postoperative complications in gastrointestinal surgery patients. Pooled estimates of pre-operative outcome data were calculated using the odds ratio (OR) and 95% confidence interval (CI). Subgroup analysis were performed to assess each type of surgery. Results The search strategy returned 1323, with 11 studies meeting the inclusion criteria. A total of 4265 patients were analysed. The prevalence of sarcopenia between studies ranged from 6.8% to 35.9%. The meta-analysis showed an OR for complications after surgery of 3.01 (95% CI 2.55-3.55) and an OR of 2.2 (95% CI 1.44-3.36) for hospital readmission (30 days). Conclusion Sarcopenia, when properly diagnosed, is associated with an increase in late postoperative complications, as well as an increase in the number of postoperative hospital readmissions for various types of gastrointestinal surgery. We believe that any preoperative evaluation should include, in a patient at risk, tests for the diagnosis of sarcopenia and appropriate procedures to reduce its impact on the patient's health.

    Background: Islets of Langerhans transplantation is a promising alternative for glycemic control in patients with type 1 diabetes. The graft site is a factor that has large impact on the functioning of this transplant, and the stomach appears to be a promising location. Our objective is to describe a new experimental model for the grafting of Islets of Langerhans in rat stomachs. Methodology: Islets of Langerhans were extracted from 45 isogenic male rats of the Lewis lineage and transplanted into 9 isogenic rats of the Wistar lineage; 5 in the gastric body submucosa, and 4 in the gastric fundus submucosa. Normoglycemia was defined as two successive measurements of < 250 mg/dL. No immunosuppression was used. The two groups glycemia control improvement were compared with t-student test. Results: The results obtained following the transplantation of the islets in 9 rats showed between 995 and 2310 islets transplanted (mean of 1367). The rats from the gastric submucosa group had a better glycemic level improvement, with a confidence equal to 83.94%. Conclusion: Islets graft into the gastric fundus submucosa is a viable model with potential for adequate glycemic control. This model gives potential for new perspectives and future studies in this area.
