Abstract Purpose: To analyze the use of this sponge in pediatric patients undergoing split-liver transplantation. Methods: Retrospective study, including 35 pediatric patients undergoing split-liver transplantation, divided into two groups according to the use of the sponge: 18 patients in Group A (no sponge) and 17 in Group B (with sponge). Results: The characteristics of recipients and donors were similar. We observed greater number of reoperation due to bleeding in the wound area in Group A (10 patients - 55.5%) than in Group B (3 patients - 17.6%); p = 0.035. The median volume of red blood cells transfused in Group A was significantly higher (73.4 ± 102.38 mL/kg) than that in Group B (35.1 ± 41.67 mL/kg); p = 0.048. Regarding bile leak there was no statistical difference. Conclusion: The use of the human fibrinogen and thrombin sponge, required lower volume of red blood cell transfusion and presented lower reoperation rates due to bleeding in the wound area.

RESUMO Objetivo: comparar o resultado do transplante de fígado por hepatocarcinoma em pacientes submetidos ou não ao tratamento loco-regional e downstaging, em relação à sobrevida e risco de recidiva na fila de transplante. Métodos: estudo retrospectivo dos pacientes portadores de hepatocarcinoma submetidos a transplante hepático na região metropolitana de São Paulo, entre janeiro de 2007 e dezembro de 2011, a partir de doador falecido. A amostra foi constituída de 414 pacientes. Destes, 29 foram incluídos na lista por downstaging. Os demais 385 foram submetidos ou não ao tratamento loco-regional. Resultados: as análises dos 414 prontuários demonstraram um predomínio de pacientes do sexo masculino (79,5%) e com média de idade de 56 anos. O tratamento dos nódulos foi realizado em 56,4% dos pacientes em fila de espera para o transplante. O método mais utilizado foi a quimio-embolização (79%). Os pacientes submetidos ao tratamento loco-regional tiveram redução significativa no tamanho do maior nódulo (p<0,001). Não houve diferença estatística entre grupos com e sem tratamento loco-regional (p=0,744) e em relação à mortalidade entre pacientes incluídos no Critério de Milão ou ao downstaging (p=0,494). Conclusões: não houve diferença na sobrevida e ocorrência de recidiva associadas ao tratamento loco-regional. Os pacientes incluídos através do processo de downstaging apresentaram resultados de sobrevida comparáveis àqueles previamente classificados como Critério de Milão/Brasil.

ABSTRACT Objective: to compare the outcome of liver transplantation for hepatocarcinoma in submitted or not to locoregional treatment and downstaging regarding survival and risk of recurrence in transplant waiting list patients. Methods: retrospective study of patients with hepatocarcinoma undergoing liver transplantation in the metropolitan region of São Paulo, between January 2007 and December 2011, from a deceased donor. The sample consisted of 414 patients. Of these, 29 patients were included in the list by downstaging. The other 385 were submitted or not to locoregional treatment. Results: the analysis of 414 medical records showed a predominance of male patients (79.5%) with average age of 56 years. Treatment of the lesions was performed in 56.4% of patients on the waiting list for transplant. The most commonly used method was chemoembolization (79%). The locoregional patients undergoing treatment had a significant reduction in nodule size greater (p<0.001). There was no statistical difference between groups with and without locoregional treatment (p=0.744) and on mortality among patients enrolled in the Milan criteria or downstaging (p=0.494). Conclusion: there was no difference in survival and recurrence rate associated with locoregional treatment. Patients included by downstaging process had comparable survival results to those previously classified as Milan/Brazil criteria.

RESUMO Racional: Estratégia cirúrgica para aumentar o número de transplantes hepáticos na população pediátrica é a transecção hepática ex-situ (redução ou split). No entanto, ela está associada com complicações, tais como hemorragia e fístulas. A esponja de fibrinogênio e trombina humana é útil para melhorar a hemostasia nas operações hepáticas. Objetivo: Comparar transplantes hepáticos pediátricos com transecção hepática ex-situ (redução ou split) com ou sem a esponja de fibrinogênio e trombina humana. Métodos: Foi realizada análise prospectiva de 21 pacientes submetidos ao transplante de fígado com transecção hepática ex-situ com a aplicação da esponja de fibrinogênio e trombina humana na área cruenta (grupo A) e análise retrospectiva de 59 pacientes sem a esponja (grupo B). Resultados: As características dos receptores e doadores eram semelhantes. Observou-se menor número de reoperações devido à hemorragia na área da cruenta no grupo A (14,2%) em comparação com o grupo B (41,7%, p=0,029). Não houve diferença em relação à fístula biliar (grupo A: 17,6%, grupo B: 5,1%, p=0,14). Conclusão: Houve menor número de reoperações por sangramento da área cruenta do enxerto hepático quando a esponja de fibrinogênio e trombina humana foi utilizada.

ABSTRACT Background: Surgical strategy to increase the number of liver transplants in the pediatric population is the ex-situ liver transection (reduction or split). However, it is associated with complications such as hemorrhage and leaks. The human fibrinogen and thrombin sponge is useful for improving hemostasis in liver surgery. Aim: Compare pediatric liver transplants with ex-situ liver transection (reduction or split) with or without the human fibrinogen and thrombin sponge. Methods: Was performed a prospective analysis of 21 patients submitted to liver transplantation with ex-situ liver transection with the application of the human fibrinogen and thrombin sponge in the wound area (group A) and retrospective analysis of 59 patients without the sponge (group B). Results: The characteristics of recipients and donors were similar. There were fewer reoperations due to bleeding in the wound area in group A (14.2%) compared to group B (41.7%, p=0.029). There was no difference in relation to the biliary leak (group A: 17.6%, group B: 5.1%, p=0.14). Conclusion: There was a lower number of reoperations due to bleeding of the wound area of the hepatic graft when the human fibrinogen and thrombin sponge were used.

PURPOSE:To perform a cost analysis of simultaneous pancreas-kidney transplantation (SPKT) in a Brazilian hospital.METHODS: Between January 2008 and December 2011, 105 consecutive SPKTs at the Hospital of Kidney and Hypertension in Sao Paulo were evaluated. We evaluated the patient demographics, payment source (public health system or supplementary system), and the impact of each hospital cost component. The evaluated costs were corrected to December 2011 values and converted to US dollars.RESULTS: Of the 105 SPKT patients, 61.9% were men, and 38.1% were women. Eight patients died, and 97 were discharged (92.4%). Eighty-nine procedures were funded by the public health system. The cost for the patients who were discharged was $18.352.27; the cost for the deceased patients was $18.449.96 (p = 0.79). The FOR for SPKT during this period was positive at $5,620.65. The costs were distributed as follows: supplies, 36%; administrative costs, 20%; physician fees, 15%; intensive care unit, 10%; surgical center, 10%; ward, 9%.CONCLUSION: Mortality did not affect costs, and supplies were the largest cost component.
