    Transplante de intestino delgado
    (2013) PÉCORA, Rafael Antonio Arruda; DAVID, André Ibrahim; LEE, André Dong; GALVÃO, Flávio Henrique; CRUZ-JUNIOR, Ruy Jorge; D'ALBUQUERQUE, Luiz Augusto Carneiro
    BACKGROUND: Small bowel transplantation evolution, because of its complexity, was slower than other solid organs. Several advances have enabled its clinical application. AIM: To review intestinal transplantation evolution and its current status. METHOD: Search in MEDLINE and ScIELO literature. The terms used as descriptors were: intestinal failure, intestinal transplantation, small bowel transplantation, multivisceral transplantation. Were analyzed data on historical evolution, centers experience, indications, types of grafts, selection and organ procurement, postoperative management, complications and results. CONCLUSION: Despite a slower evolution, intestinal transplantation is currently the standard therapy for patients with intestinal failure and life-threatening parenteral nutrition complications. It involves some modalities: small bowel transplantation, liver-intestinal transplantation, multivisceral transplantation and modified multivisceral transplantation. Currently, survival rate is similar to other solid organs. Most of the patients become free of parenteral nutrition.

    LATE ACUTE REJECTION IN LIVER TRANSPLANT: A SYSTEMATIC REVIEW
    (2015) NACIF, Lucas Souto; PINHEIRO, Rafael Soares; PÉCORA, Rafael Antônio de Arruda; DUCATTI, Liliana; ROCHA-SANTOS, Vinicius; ANDRAUS, Wellington; D'ALBUQUERQUE, Luiz Carneiro
    Introduction: Late acute rejection leads to worse patient and graft survival after liver transplantation. Aim: To analyze the reported results published in recent years by leading transplant centers in evaluating late acute rejection and update the clinical manifestations, diagnosis and treatment of liver transplantation. Method: Systematic literature review through Medline-PubMed database with headings related to late acute rejection in articles published until November 2013 was done. Were analyzed demographics, immunosuppression, rejection, infection and graft and patient survival rates. Results:Late acute rejection in liver transplantation showed poor results mainly regarding patient and graft survival. Almost all of these cohort studies were retrospective and descriptive. The incidence of late acute rejection varied from 7-40% in these studies. Late acute rejection was one cause for graft loss and resulted in different outcomes with worse patient and graft survival after liver transplant. Late acute rejection has been variably defined and may be a cause of chronic rejection with worse prognosis. Late acute rejection occurs during a period in which the goal is to maintain lower immunosuppression after liver transplantation. Conclusion: The current articles show the importance of late acute rejection. The real benefit is based on early diagnosis and adequate treatment at the onset until late follow up after liver transplantation.

    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 Carneiro
    BACKGROUND: 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.
