ABSTRACT
O transplante hepático (Tx) pediátrico é o tratamento definitivo e indicado para doenças hepáticas terminais. Nele, estão envolvidos dois cenários: o da criança receptora e do doador, que abrangem questões como a saúde geral e bucal, imunossupressão e qualidade de vida. A imunossupressão pode acarretar infecções oportunistas como os poliomavírus BK e JC que causam complicações clínicas no pós-transplante. Assim, esta pesquisa trata-se de um estudo longitudinal que se propôs avaliar três vertentes: i) as condições odontológicas das crianças no processo do transplante hepático; ii) avaliar a excreção oral e viremia dos poliomavírus BK e JC nas crianças antes e após o Tx; iii) avaliar o impacto da qualidade de vida (QV) dos doadores. Para analisar as vertentes relacionadas ao receptor, foram incluídas 84 crianças em programação para o transplante hepático no Hospital Municipal Infantil Menino Jesus em São Paulo, mas apenas 51 fizeram parte da amostra final. Foram utilizadas as categorias avaliativas do Bedside Oral Exam BOE para avaliar as condições bucais pré- e pós-transplante imediato. Juntamente com o exame clínico bucal, foram realizadas seis coletas, uma pré-transplante e cinco semanalmente no pós-transplante, de saliva e sangue para avaliar a presença dos poliomavírus. Em contrapartida, para avaliar a QV dos doadores, participaram desse estudo 25 adultos. Para essa avaliação foi utilizado o questionário SF-36 versão 2, que é autoaplicável e aborda oito domínios sobre a saúde física e emocional, sendo aplicado no pré-Tx (um dia anterior a cirurgia) e no pós-Tx (um mês após a cirurgia). As análises estatísticas utilizadas para cada objetivo foram: i) análise descritiva das condições bucais nos dois momentos e comparadas através do teste de Wilcoxon; ii) análise da variável dicotômica e o teste de McNemar para identificar a presença do BK e JC; iii) teste de Shapiro-Wilk, seguido pela comparação dos dados paramétricos pelo teste t pareado e dados não paramétricos pelo teste de Wilcoxon considerando significância estatística de p<0,05 para a avaliação da QV do doador. As análises foram realizadas através do software JAMOVI. Assim, os resultados encontrados para cada objetivo foram: i) no pré-transplante a característica mais frequente foi à alteração de cor nas mucosas (78.6% n=84) e no pós-transplante alteração nos lábios (27.4% n=51), na função deglutição (13.8% n=51) e na cor dos dentes (27.4% n=51); apesar disso as crianças apresentavam BOE escore 8, 9 ou 10 tanto no pré-transplante (92.8% n=84) como no pós-transplante (90.4% n=51); ii) em relação à excreção oral e viremia dos poliomavírus, apenas observamos a presença do BK na saliva em uma amostra (2%) na segunda e uma amostra (2%) na quinta semana pós-Tx; e no plasma em uma amostra (2%) na terceira e em uma amostra (2%) na quinta semana pós-Tx. O JC não foi detectado em nenhuma das amostras analisadas; iii) em relação à QV do doador, foi possível verificar uma diferença estatisticamente significativa nos domínios relacionados à capacidade funcional (média no pré-Tx= 85.4 e média no pós-Tx= 47.6; p<0.001), limitação por aspectos físicos (média no pré-Tx= 82.5 e média no pós-Tx= 52.5; p<0.001), dor (média no pré-Tx= 83.9 e média no pós-Tx= 60.5; p=0.002) e limitação por aspectos emocionais (média no pré-Tx= 82.5 e média no pós-Tx= 52.5; p<0.001). Conclui-se que as crianças possuíam uma boa condição bucal no pré e pós-transplante apesar de terem sido encontradas alterações na mucosa no pré-transplante e alterações em lábios e dentes no pós-transplante. A presença do poliomavírus BK é um evento raro em pacientes pediátricos no processo de transplante hepático. No que diz respeito ao impacto da QV nos doadores, houve uma piora no pós-transplante considerando os aspectos físicos e emocionais.

Objective: To examine the clinical effect of auxiliary liver transplantation with ultra-small volume graft in the treatment of portal hypertension. Methods: Twelve cases of portal hypertension treated by auxiliary liver transplantation with small volume graft at Liver Transplantation Center,Beijing Friendship Hospital, Capital Medical University between December 2014 and March 2022 were studied retrospectively. There were 8 males and 4 females,aged 14 to 66 years. Model for end-stage liver disease scores were 1 to 15 points and Child scores were 6 to 11 points. The grafts was derived from living donors in 9 cases,from split cadaveric donors in 2 cases,from whole cadaveric liver of child in 1 case. The graft recipient body weight ratios of 3 cadaveric donor livers were 0.79% to 0.90%, and of 9 living donor livers were 0.31% to 0.55%.In these cases, ultra-small volume grafts were implanted. The survivals of patient and graft, complications, portal vein blood flow of residual liver and graft, abdominal drainage and biochemical indexes of liver function were observed. Results: All the grafts and patients survived. Complications included outflow tract torsion in 2 cases, acute rejection in 1 case, bile leakage in 1 case, and thyroid cancer at the later stage of follow-up in 1 case, all of which were cured. The torsion of outflow tract was attributed to the change of anastomotic angle after the growth of donor liver. After the improvement of anastomotic method, the complication did not recur in the later stage. There was no complication of portal hypertension. The measurement of ultrasonic portal vein blood flow velocity showed that the blood flow of residual liver decreased significantly in the early stage after operation, and maintained a very low blood flow velocity or occlusion in the long term after operation, and the blood flow of transplanted liver was stable. Conclusions: Auxiliary liver transplantation can implant ultra-small donor liver through compensation of residual liver. This method may promote the development of living donor left lobe donation and split liver transplantation. However, the auxiliary liver transplantation is complex, and it is difficult to control the complications. Therefore, this method is currently limited to centers that are skilled in living related liver transplantation and that have complete ability to monitor and deal with complications.

ABSTRACT BACKGROUND: Liver transplantation represents the best therapeutic modality in end-stage chronic liver disease, severe acute hepatitis, and selected cases of liver tumors. AIMS: To describe a double retransplant in a male patient diagnosed with Crohn's disease and complicated with primary sclerosing cholangitis, severe portal hypertension, and cholangiocarcinoma diagnosed in the transplanted liver. METHODS: A 48-year-old male patient diagnosed with Crohn's disease 25 years ago, complicated with primary sclerosing cholangitis and severe portal hypertension. He underwent a liver transplantation in 2018 due to secondary biliary cirrhosis. In 2021, a primary sclerosing cholangitis recurrence was diagnosed and a liver retransplantation was indicated. Recipient's hepatectomy was very difficult by reason of complex portal vein thrombosis requiring extensive thromboendovenectomy. Intraoperative ultrasound with liver doppler evaluation was performed. Two suspicious nodules were incidentally diagnosed in the donor's liver and immediately removed for anatomopathological evaluation. RESULTS: After pathological confirmation of carcinoma, probable cholangiocarcinoma, at frozen section, the patient was re-listed as national priority and a new liver transplantation was performed within 24 hours. The patient was discharged after 2 weeks. CONCLUSIONS: The screening for neoplasms in donated organs should be part of our strict daily diagnostic arsenal. Moreover, we argue that, for the benefit of an adequate diagnosis and the feasibility of a safer procedure, the adoption of imaging tests routine for the liver donor is essential, allowing a reduction of the costs and some potential risks of liver transplant procedure.
RESUMO RACIONAL: O transplante de fígado representa a melhor modalidade terapêutica na doença hepática crônica terminal, hepatite aguda grave e casos selecionados de tumores hepáticos. OBJETIVOS: Descrever um retransplante duplo em paciente do sexo masculino, diagnosticado com doença de Crohn e complicado com colangite esclerosante primária, hipertensão portal grave e colangiocarcinoma diagnosticado no fígado transplantado. MÉTODOS: Paciente do sexo masculino, 48 anos, diagnosticado com doença de Crohn há 25 anos e complicado com colangite esclerosante primária e hipertensão portal grave. Foi submetido a um transplante de fígado em 2018 devido a cirrose biliar secundária. Em 2021, foi diagnosticada recidiva de colangite esclerosante primária e indicado retransplante hepático. A hepatectomia do receptor foi de alta complexidade devido à trombose complexa da veia porta, exigindo extensa tromboendovenectomia. Foi realizada ultrassonografia intraoperatória com doppler hepático. Dois nódulos suspeitos foram diagnosticados incidentalmente no fígado do doador e imediatamente removidos para avaliação anatomopatológica. RESULTADOS: Após confirmação patológica de carcinoma, provável colangiocarcinoma, pela congelação, o paciente foi relistado como prioridade nacional, e novo transplante hepático foi realizado em 24 horas. O paciente teve alta após 2 semanas. CONCLUSÕES: O rastreamento de neoplasias em órgãos doados deve fazer parte de nosso estrito arsenal diagnóstico diário. Além disso, defendemos que, em benefício de um diagnóstico correto e da viabilidade de um procedimento mais seguro, a adoção de uma rotina de exames de imagem é essencial em doadores hepáticos, permitindo a redução dos custos e alguns riscos potenciais do procedimento de transplante hepático.

Introducción: El trasplante es la opción terapéutica más favorable para las personas con insuficiencia renal crónica. El donante puede ser cadavérico o donante vivo, emparentado o no. Los resultados del trasplante están en relación con varios factores inmunológicos y no inmunológicos. Objetivo: Caracterizar inmunogenéticamente a los donantes cadavéricos cubanos para trasplante renal. Métodos: Se realizó un estudio transversal y descriptivo de los donantes cadavéricos durante el año 2019. Se analizó la región de procedencia, sexo, color de la piel y rangos de edades de los donantes, así como, grupo sanguíneos ABO y Rhesus Rh; serología para VIH, Virus de hepatitis B(VHB) y Virus de hepatitis C (VHC); y hábitos tóxicos. Resultados: Se estudió un total de 95 donantes cadavéricos, 62 provenientes del occidente y 33 del centro del país. El 63,2 por ciento fueron masculinos y 36,8 por ciento femenino. El grupo de edad de mayor frecuencia fue 40 - 60 años y la edad media de 49,45 años. El 58,95 por ciento de los pacientes fueron de grupo sanguíneo O; 30,53 por ciento grupo A y los grupos B y AB tuvieron 5,26 por ciento de prevalencia; y solo 8 fueron Rh negativos. Todos tuvieron serología para VIH, VHB y VHC negativas. Las enfermedades asociadas más frecuentes fueron la hipertensión arterial y la diabetes mellitus. Conclusiones: Los donantes cadavéricos durante el año 2019 mostraron características similares a las reportadas por otros estudios. El aumento de las edades de los donantes incide en la aparición de enfermedades asociadas y esto pudiera repercutir en el resultado del trasplante(AU)
Introduction: Transplantation is the most favorable therapeutic option for people with chronic renal failure. The donor can be a cadaveric or living donor, related or not. Transplant outcomes are related to various immunological and non-immunological factors. Objective: To characterize Cuban cadaveric donors for renal transplantation Materials and methods: A cross-sectional and descriptive study of cadaveric donors was carried out during the year 2019. The region of origin, sex, skin color and age ranges of the donors were analyzed, as well as ABO and Rhesus Rh blood groups; serology for HIV, Hepatitis B Virus (HBV) and Hepatitis C Virus (HCV), and toxic habits. Results: A total of 95 cadaveric donors were studied, 62 from the West and 33 from the Center of the country. 63.2 percent were male and 36.8 percent female due to the most frequent age group being 40-60 years and the mean age of 49.45 years. 58.95 percent of the patients were of blood group O, 30.53 percent group A and groups B and AB had 5.26 percent prevalence; and only 8 were Rh negative. All had negative serology for HIV, HBV and HCV. The most frequent associated diseases were arterial hypertension and diabetes mellitus. Conclusions: The cadaveric donors during the year 2019 showed characteristics similar to those reported by other studies.

Resumen El trasplante hepático con donante vivo (THDV) es un procedimiento complejo y desafiante para el cirujano, ya que exige garantizar tanto la máxima seguridad para el donante, así como también, la mejor calidad del injerto para el receptor. Debido a lo anterior, la implementación de la cirugía mini-invasiva ha sido lenta en esta área. Sin embargo, en los últimos 10 años, gracias a los avances que ha experimentado la cirugía hepática laparoscópica, ha aumentado el interés de algunos grupos altamente especializados por incorporar la cirugía mini-invasiva a la cirugía del donante, principalmente en trasplante hepático donante vivo adulto-pediátrico (THDVA-P). Los favorables resultados obtenidos en esta área incluso han llevado a los expertos en el tema, a categorizar el abordaje laparoscópico para la cirugía del donante como el procedimiento estándar en THDVA-P. Contrario a lo anterior, la implementación de la laparoscopía para trasplante hepático donante vivo adulto-adulto (THDVA-A), es más compleja y requiere en su mayoría, una hepatectomía de lóbulo derecho o izquierdo para cumplir con las necesidades volumétricas del receptor. Esta cirugía es de mayor dificultad y riesgo para el donante, por lo que su indicación por vía mini-invasiva está limitada a centros de alto volumen y preparación, tanto en laparoscopía, como en trasplante hepático. En este trabajo, se busca dar a conocer la técnica quirúrgica y nuestra experiencia inicial con la primera hepatectomía derecha totalmente laparoscópica (HDTL) para THDVA-A realizada en Chile.
Living donor liver transplantation is a complex and challenging procedure. The surgeon needs to guarantee maximum safety for the donor, as well as the best quality of the graft for the recipient. For this reason, the implementation of mini-invasive surgery has been slow in this area. However, in the last 10 years, due to the advances in laparoscopic liver surgery, the interest of some highly specialized groups has increased in incorporating mini-invasive surgery into donor surgery, mainly in pediatric living donor liver transplantation. The favorable results obtained in this field, have even led to turn this procedure, into the technique of choice for pediatric living donor liver transplantation. Nevertheless, this procedure is even more challenging for adult-to-adult living donor transplantation. To meet the volumetric criteria of an adult, a complete hepatectomy of right or left lobe is mostly required. This surgery is of greater complexity and risk for the donor, so its indication by minimally invasive approach is limited to high-volume centers with preparation, both in laparoscopy and liver transplants. In this report we seek to present our surgical technique and initial experience with the first pure laparoscopic right hepatectomy for adult-to-adult living donor liver transplantation carried out in Chile.

OBJETIVO:analisar as narrativas que marcam a trajetória de vida dos doadores renais. METODOLOGIA:pesquisa exploratória, descritiva e de abordagem qualitativa. Após a apreensão e preparo analítico dos relatos gravados em áudio, por meio da técnica da história oral de vida, realizou-se a análise de conteúdo de Bardinque consiste das etapas: pré-análise, exploração do material ou codificação, tratamento dos resultados, inferência e interpretação dos eixos temáticos que emergiram. RESULTADOS:a amostra de 12 doadores renais que se submeteram ao transplante no Hospital Universitário Onofre Lopes-UFRN, respondeu às questões norteadoras: como era sua vida antes da doação renal? Como é sua vida após a doação renal? As narrativas convergiram para as temáticas "experiências vividas antes da doação renal" e "experiências vividas após a doação renal". Os colaboradores enredaram o acometimento da doença como um momento trágico e a doação renal como meio de minimizar o sofrimento vivido pela família.CONCLUSÃO:os colaboradores reconhecem mais interferências positivas da doação renal, principalmente a melhoria na qualidade de vida dos doadores e o reconhecimento social da nobreza do ato da doação renal
OBJECTIVE:to analyze how narratives that mark the life trajectory of renal donors.METHODOLOGY: Exploratory, descriptive research and a qualitative approach. After the apprehension and analytical preparation of the audio recorded reports, using the oral life history technique, Bardin's content analysis was carried out, which consists of the stages: pre-analysis, exploration of the material or coding, treatment of results, inference and interpretation of the thematic axes that emerged. RESULTS:The sample of 12 kidney donors who underwent transplantation at Hospital UniversitarioOnofre Lopes-UFRN, answered the guiding questions: How was your life before kidney donation. How is your life after kidney donation. The narratives converged on the themes "experiences lived before kidney donation" and "experiences lived after kidney donation".Employees identified the disease as a tragic moment and kidney donation as a means of minimizing the suffering experienced by the family. CONCLUSION:Employees recognize more positive interferences from kidney donation, mainly the improvement in the quality of life of donors and the social recognition of the nobility of the kidney donation act.

Background: The negative impact of tobacco smoking on renal function has been widely studied. However, there is limited knowledge about the effect of smoking on pre-operative and post-operative renal function in living kidney donors. Objective: The objective of the study was to evaluate the short- and mid-term impact of smoking on donor renal function. Methods: This is a retrospective study of 308 patients who underwent living donor nephrectomy (LDN) at a tertiary referral hospital. We compared baseline characteristics as well as functional outcomes following LDN according to history of tobacco smoking. Estimated glomerular filtration rate (eGFR) was calculated with the modification of diet in renal disease equation in 6 time periods: pre-operative, 1 week, 1 month, 6 months, 12 months, and 24 months after surgery. We performed a Kaplan-Meier analysis for chronic kidney disease (CKD) outcome and binary logistic regression analysis to identify risk factors associated with CKD at 24 months of follow-up. Results: Among donors, 106 (34.4%) reported a smoking history before nephrectomy. Smoking donors had worse pre-operative eGFR than non-smokers (90 ± 26.3 mL/min/1.73m2 vs. 96 ± 27 mL/min/1.73 m2, respectively; p = 0.02) and lower eGFR at 1 week (p = 0.01), 1 month (p ≤ 0.01), 6 months (p = 0.01), and 12 months (p = 0.01) after LDN. Tobacco smoking (OR 3.35, p ≤ 0.01) and age ≥ 40 years at donation (OR 6.59, p ≤ 0.01) were associated with post-operative development of CKD at 24 months after LDN. Conclusions: Living kidney donors with a tobacco smoking history had an increased risk of developing chronic kidney disease following nephrectomy. Smoking-cessation strategies should be implemented.

Abstract The aim of this study was to determine the incidence of preservation fluids (PF) bacterial positive cultures, identify the germs involved, determine their correlation with infections in recipients during the postoperative period and compare outcomes in terms of morbidity, hospital stay and both patient and graft survival. We describe incidence and etiology of germs developed in PF cultures in our series and evaluate its impact on recipients. A prospective study in deceased donor liver transplants (LT) recipients was carried out from January 2014 to December 2017. Back table PF cultures were analized considering positive the development of any germs and negative to no signs of growth after 5 days. PF were classified as contamination or pathogens. Targeted antibiotic therapy was administered in the last ones. Recipients were divided in: PF (-) and PF(+). Recipients infections related to positive PF were analyzed. These were identified as "direct correlation" when the same germ grew up in PF. Hospital stay and 30 days follow up were compared. Eighty-eight patients PFs were included, 38% (33) had positive cultures, 28 (85%) of these were considered contamination and only 5 as pathogens. We found no differences in postoperative infections (p 0.840), ICU and total hospital stay (p 0.374 and 0.427) between both groups. Postoperative infections and hospital stay seem not to be influenced by PF cultures positivity. Treatment of isolated pathogens could have prevented infections, therefore, those groups that perform PF cultures should consider treatment in these cases and conclude prophylaxis when PF is negative or contaminated.
Resumen Las infecciones bacterianas son frecuentes en pacientes sometidos a trasplante hepático. Describimos la incidencia y etiología de los cultivos de líquidos de preservación (LP) positivos en nuestra serie y analizamos su importancia clínica. Se trata de un trabajo prospectivo de pacientes trasplantados hepáticos, entre enero 2014 a diciembre 2017. Se analizaron muestras de LP tomadas al finalizar la mesa de banco, considerándose positivo el desarrollo de cualquier germen y negativo la ausencia del mismo luego de 5 días. Los LP positivos se clasificaron en: con contaminantes y con patógenos. Los pacientes con LP patógenos recibieron tratamiento antibiótico de acuerdo al antibiograma. Los pacientes fueron divididos en dos grupos: con LP + y LP-. Las infecciones relacionadas a los LP fueron analizadas. Se consideró "correlación directa" cuando el mismo germen desarrolló en el LP y en el recipiente. Se comparó estadía hospitalaria en ambos grupos. Se incluyeron 88 pacientes, 38% (33) presentaron LP+, de los que el 85% (28) fueron por contaminación y 5 por pa tógenos. No se hallaron diferencias significativas en infecciones postoperatorias (p 0.840) y estadía hospitalaria (p 0.427) entre ellos. No hubo casos de "correlación directa". Las infecciones postoperatorias y la estadía hospitalaria de los pacientes no parecen estar influidas por la positividad de los cultivos de LP. El tratamiento dirigido a los gérmenes aislados como patógenos pudo prevenir infecciones, por lo tanto, los grupos que realizan cultivos de rutina deberían considerar el tratamiento en estos casos y finalizar la profilaxis cuando el LP sea negativo o contaminado.

Summary OBJECTIVE: This study was designed to compare the standard and robotic-assisted laparoscopic donor nephrectomy in terms of perioperative course, short-term postoperative outcome, and to evaluate the effect of surgeon's learning curve on these parameters. METHODS: This was a prospective randomized study including 60 patients (mean age, 47 years; age, 21-72 years; 26 males, 34 females) who had been planned laparoscopic donor nephrectomies in our clinic. For comparison of standard and robot-assisted techniques and to evaluate the impact of learning curve, patients were randomized into three groups by a computer, each group containing 20 patients. Group 1: standard laparoscopic donor nephrectomies; Group 2: the first 20 patients who underwent robot-assisted laparoscopic donor nephrectomy; and Group 3: the next 20 patients who underwent robot-assisted laparoscopic donor nephrectomy. RESULTS: Operative time was significantly higher in Group 2 (221.0±45.1 min) than both Group 1 (183.5±16.9 min, p=0.001) and Group 3 (186.5±20.6 min, p=0.002). Similarly, time for laparoscopic system setup was significantly higher in Group 2 (39.5±8.6 min), which contained the first cases of robot-assisted laparoscopic donor nephrectomy where surgeon had least experience than Group 1 (19.3±3.7 min, p<0.001) and Group 3 (24.0±9.4 min, p<0.001). On the other hand, duration of operation and time for laparoscopic system setup was similar between Groups 1 and 3. CONCLUSIONS: Learning curve extends the operative time and laparoscopic system setup time in robotic-assisted laparoscopic donor nephrectomy, however, after the learning process was completed, these parameters were similar between robotic-assisted and standard laparoscopic nephrectomy.

ABSTRACT BACKGROUND: Receptors of living donor liver transplantation (LDLT) have higher rate of postoperative biliary and vascular complications that may reduce posttransplant quality of life (QOL) due to the need of invasive and repetitive treatments. OBJECTIVE: The purpose of our study is to assess the various aspects of QOL of receptors undergoing LDLT after 10 years of transplantation and to identify potential factors that might be associated with impaired QOL. METHODS: Data of all patients with more than 10 years of LDLT were retrospectively evaluated. Patients were interviewed through a quality of life questionnaire (SF-36). RESULTS: From a total of 440 LT performed in 17 years (from September 1991 through December 2008), 78 patients underwent LDLT, of which 27 were alive and 25 answered completely the questionnaire. There were 17 (68%) men and 8 (32%) women, with a mean age of 38.6±18.5 years at the time of transplantation and mean follow up time of 15.1±1.9 years. The average MELD was 16.4±4.9 and the main indication for LT was hepatic cirrhosis caused by hepatitis B virus (32%). When compared to the general population, LDLT patients had lower mental health score (66.4 vs 74.5, P=0.0093) and higher vitality score (87.8 vs 71.9, P<0.001), functional aspects (94.6 vs 75.5, P=0.002), social aspects (93 vs 83.9, P=0.005), physical aspects (92 vs 77.5, P=0.006), and emotional aspects (97.33 vs 81.7, P<0.001). General health status (73.28 vs 70.2, P=0.074) and pain (78.72 vs 76.7, P=0.672) scores were similar in both groups. CONCLUSION: It is concluded that the various aspects LDLT recipients' QOF are similar to those of the general population more than a decade after the transplant, except for the mental health domain which is lower.
RESUMO CONTEXTO: Receptores de transplante hepático inter-vivo (THIV) apresentam elevada taxa de complicações biliares e vasculares pós-operatórias que podem reduzir a qualidade de vida (QV) devido à necessidade de tratamentos invasivos e repetitivos. OBJETIVO: O objetivo deste estudo é avaliar os vários aspectos da qualidade de vida dos pacientes submetidos a THIV após 10 anos de transplante e identificar possíveis fatores que possam estar associados à diminuição da QV. MÉTODOS: Os dados de todos os pacientes com mais de 10 anos de THIV foram avaliados retrospectivamente. Os pacientes foram entrevistados por meio de um questionário de qualidade de vida (SF-36). RESULTADOS: Do total de 440 transplantes hepáticos realizados em 17 anos (setembro de 1991 a dezembro de 2008), 78 pacientes foram submetidos a THIV, dos quais 27 estavam vivos e 25 responderam completamente ao questionário. Destes, 17 (68%) homens e 8 (32%) mulheres, com idade média de 38,6±18,5 anos no momento do transplante e tempo médio de acompanhamento de 15,1±1,9 anos. O MELD médio foi de 16,4±4,9 e a principal indicação para o transplante hepático foi cirrose hepática causada pelo vírus da hepatite B, 32%. Quando comparado com a população geral, os pacientes submetidos a THIV apresentaram menor escore de saúde mental (66,4 vs 74,5; P=0,0093) e escores mais altos de vitalidade (87,8 vs 71,9; P<0,001), aspectos funcionais (94,6 vs 75,5; P=0,002), aspectos sociais (93 vs 83,9; P=0,005), aspectos físicos (92 vs 77,5; P=0,006), e aspectos emocionais (97,33 vs 81,7; P<0,001). Os escores do estado geral de saúde (73,28 vs 70,2; P=0,074) e de dor (78,72 vs 76,7; P=0,672) eram similares nos dois grupos. CONCLUSÃO: Conclui-se que os vários aspectos da QV dos receptores de transplante hepático inter-vivo são semelhantes aos da população geral mais de uma década após o transplante, exceto o domínio da saúde mental que é menor.

O transplante é um procedimento cirúrgico que consiste na reposição de um órgão (coração, pulmão, rim, pâncreas, fígado) ou tecido (medula óssea, ossos, córneas) de uma pessoa doente (receptor), por outro órgão ou tecido normal de um doador vivo ou morto. São classificados por dois tipos, sendo doador falecido e doador vivo. Neste último, apenas maiores de idade e capaz juridicamente poderão doar e o procedimento ocorre de modo a preservar a qualidade de vida e a manutenção fisiológica do doador, salvaguardando a segurança do indivíduo, concomitante a espontaneidade da doação. Esta nota técnica tem como objetivo orientar e organizar o fluxo para a realização do transplante com doador vivo em Goiás, de modo a atender a necessidade social e médica, preservando os princípios legais e norteadores do processo
Transplantation is a surgical procedure that consists of replacing an organ (heart, lung, kidney, pancreas, liver) or tissue (bone marrow, bones, corneas) from a sick person (recipient) with another organ or normal tissue from a living or dead donor. They are classified by two types, being deceased donor and living donor. In the latter, only those of legal age and legal capacity can donate and the procedure takes place in order to preserve the quality of life and maintenance physiological function of the donor, safeguarding the individual's safety, concomitant with the spontaneity of the donation. This technical note aims to guide and organize the flow for carrying out the transplant with a live donor in Goiás, in order to meet the social and medical needs, preserving the legal and guiding principles of the process

ABSTRACT Objective: To understand the professionals´ perception of the use of deceased donor liver for transplantation, the reasons to decline them, and propose strategies to increase their use safely. Methods: This is a cross-sectional, descriptive qualitative-quantitative study. Professionals working with liver transplantation answered a self-administered, structured, and electronic questionnaire comprising 17 questions distributed into four sessions (demographic factors, perception of use of organs, reasons for disposal, and measures to favor their usage). Results: A total of 42 professionals participated in the study. The rate of use of organs was considered low by 71.43% (n=30) of respondents or very low by 19.05% (n=8). Everyone agreed that it was possible to increase it. Thirty-one (73.81%) participants believed the expansion of the population of extended criteria donors affected this index negatively. Donor-related conditions were the most frequent category of reasons for refusing a liver for transplantation, being the findings during organ retrieval the most frequent reason in clinical practice. Enhanced training of intensive care teams in the treatment of donors was the primary measure selected to favor the use of the organs, followed by investment in new technologies to optimize its preservation/evaluate its function before transplantation. Conclusion: Implementation of strategies to increase the rate of acceptance of livers is expected. Improvements in donor intensive care and implementation of new preservation technologies should favor the use of the organs.
RESUMO Objetivo: Compreender a percepção dos profissionais acerca do uso de fígado de doadores falecidos para transplante e os motivos para sua recusa, além de propor estratégias para ampliar sua utilização com segurança. Métodos: Estudo do tipo transversal, descritivo qualiquantitativo.Profissionais que trabalhavam com transplante hepático responderam a um questionário autoaplicável, estruturado e eletrônico, composto de 17 questões distribuídas em quatro seções (fatores demográficos, percepção sobre a utilização dos órgãos, razões para o descarte e medidas para favorecer sua utilização). Resultados: Participaram do estudo 42 profissionais. A taxa de utilização dos órgãos foi considerada baixa por 71,43% (n=30) dos respondentes ou muito baixa por 19,05% (n=8). Todos concordaram que era possível aumentá-la. Trinta e um (73,81%) participantes acreditavam que a expansão da população de doadores de critérios estendidos impacta negativamente nesse índice. Condições relacionadas ao doador foi a categoria mais frequente de razões para a recusa de um fígado para transplante, sendo os achados durante a cirurgia de extração o motivo mais frequente na prática clínica. O melhor treinamento das equipes da terapia intensiva nos cuidados com os doadores foi a principal medida selecionada para favorecer a utilização dos órgãos, seguido pelo investimento em novas tecnologias para otimizar sua preservação/avaliar sua função antes do transplante. Conclusão: A efetivação de estratégias para aumentar a taxa de aceite de fígados de doadores é aguardada. Melhorias no cuidado intensivo do doador e a implementação de novas tecnologias de preservação devem favorecer a utilização desses órgãos.

SUMMARY OBJECTIVE: This study aims to describe the result of the strategies adopted to maintain the transplant program amid the COVID-19 pandemic. METHODS: Since March 2020, several measures have been adopted sequentially, including the compulsory use of personal protective equipment and the real-time polymerase chain reaction testing of collaborators, symptomatic patients, potential deceased donors, candidates for recipients, and in-hospital readmissions, regardless of symptoms. The living-donor transplantation was restricted to exceptional cases. RESULTS: Among 1013 health professionals, 201 cases of COVID-19 were confirmed between March and August 2020, with no severe cases reported. In this period, we observed a 19% institutional increase in the number of transplants from deceased donors compared with that observed in the same period in 2019. There was no donor-derived severe acute respiratory syndrome virus (SARS-CoV-2) infection. Four COVID-19-positive patients underwent transplantation; after 28 days, all were alive and with functioning allograft. Among the 11,875 already transplanted patients being followed up, there were 546 individuals with confirmed diagnosis, 372 who required hospitalization, and 167 on mechanical ventilation, resulting in a 27% mortality rate. CONCLUSIONS: These data confirm that the adoption of sequential and coordinated measures amid the pandemic was able to successfully maintain the transplant program and ensure the safety of health professionals and transplanted patients who were already in follow-up.

INTRODUCTION@#Hepatic artery reconstruction is a critical aspect of liver transplantation. The microsurgeon faces several challenges when reconstructing the hepatic artery-the donor hepatic artery stalk is short and often a poor match for the usually hypertrophic recipient vessels. Previous inflammation impedes vessel dissection, and recipient vessels have a tendency to delaminate with manipulation. We review 51 consecutive liver transplantations to highlight these problems and propose strategies for a successful reconstruction of the hepatic artery.@*METHODS@#A prospective study involving all adult patients undergoing liver transplantation at the Singapore General Hospital from January 2015 to December 2018 was undertaken. All hepatic artery anastomoses were performed by 2 microsurgeons at 10x magnification. Patients were started on a standard immunosuppressive regimen. Postoperative ultrasound scans on days 1, 3, 5, 7, 9 and 14 were used to confirm arterial patency.@*RESULTS@#There were 51 patients who underwent liver transplantation during the study period. Of this number, 31 patients received deceased donor grafts and 20 received living donor grafts. A total of 61 anastomoses were performed (5 dual anastomosis, 4 radial artery interposition grafts) with 1 case of hepatic artery thrombosis that was successfully salvaged. The mean (range) postoperative resistive index and hepatic artery peak systolic velocity were 0.69 (0.68-0.69) and 1.0m/s (0.88-1.10m/s), respectively.@*CONCLUSION@#Hepatic artery thrombosis after liver transplantation is poorly tolerated. The challenges of hepatic artery reconstruction in liver transplantation are related to vessel quality and length. The use of microsurgical technique, appropriate recipient vessel selection, minimisation of vessel manipulation with modified instruments, variation in anastomosis techniques, and use of radial artery interpositional grafts are useful strategies to maximise the chances of success.

This paper introduced a liver normothermic machine perfusion repair and assessment system. This system consists of a liver normothermic machine perfusion device, a fluorescence imaging system and a tissue oxygen detector. The normothermic machine perfusion device can continuously perfuse the donor liver and monitor and control the perfusion parameters in real time. The fluorescence imaging system can detect the indocyanine green metabolized by the liver to evaluate the microcirculation and the metabolism function of hepatocytes. The tissue oxygen detector can monitor the change of oxygen partial pressure of liver tissue in real time to evaluate the state of cell oxygen consumption.

En relación a la hepatectomía laparoscópica para donante vivo en trasplante hepático (TH), ésta se ha retrasado aún más por las preocupaciones sobre la seguridad del donante, el resultado del injerto y la adquisición de las competencias técnicas de los cirujanos. El objetivo de este artículo, es exponer detalles técnicos de la hepatectomía izquierda laparoscópica de donantes vivos adultos para trasplante pediátrico y se presentan los resultados quirúrgicos de los casos realizados en este centro. Materiales y Método: Presentación de la técnica quirúrgica de la hepatectomía izquierda en donantes vivos para TH en receptores pediátricos, además, de realizar un estudio cohorte no concurrente de pacientes sometidos a esta cirugía en el Hospital Clínico de la Universidad Católica entre mayo de 2011 y noviembre de 2017. Resultados: La serie consta de 15 pacientes, 60% sexo femenino. Trece pacientes (86,6%) eran madre o padre del receptor. El 100% de pacientes fue sometido a hepatectomía izquierda laparoscópica sin necesidad de conversión. Morbilidad Clavien-Dindo >3,1 paciente requirió punción percutánea de bilioma. Mediana de hospitalización de 3 días (2-5). No hubo mortalidad. Conclusión: La hepatectomía izquierda por vía laparoscópica de donante vivo para TH pediátrico es un procedimiento seguro y factible de realizar en este centro, con excelentes resultados en términos de morbimortalidad y consideramos que esta técnica debe ser la vía de elección para donantes vivos adultos-pediátricos.
Introduction: Laparoscopic liver surgery has presented a slower development due to the complexity it has, which determines a prolonged learning curve. In relation to laparoscopic hepatectomy for a living donor liver transplantation (LT), this has been further delayed due to concerns about donor safety, graft results and the acquisition of the technical skills of surgeons. The objective of this article is to present technical details of the laparoscopic left hepatectomy of adult living donors for pediatric transplantation and the surgical results of the cases performed in this center. Materials and Method: Presentation of the surgical technique of left hepatectomy in living donors for LT in pediatric recipients in addition to conducting a non-concurrent cohort study of patients undergoing this surgery at the Hospital Clinico Universidad Catolica between May 2011 to November 2017. Results: The series consists of 15 patients, 60% female. Thirteen patients (86.6%) were mother or father of the recipient. 100% of patients underwent laparoscopic left hepatectomy without conversion. Clavien-Dindo Morbidity > 3, in 1 patient who required percutaneous drainage of biloma. Median hospitalization of 3 days (2-5). There was no mortality. Conclusión: Laparoscopic left hepatectomy of living donors for pediatric LT is a safe and feasible procedure to perform in this center, with excellent results in terms of morbidity and mortality and we consider that this technique should be the route of choice for adult-pediatric living donors.

ABSTRACT BACKGROUND Biliary complications remain one of the most important causes of morbidity and graft loss after liver transplant (LT). Endoscopic therapy of biliary complications has proven to be effective over time, leaving surgical treatment restricted to only very few cases. However, we cannot yet predict which patients will have the greatest potential to benefit from endoscopic treatment. OBJECTIVE On this premise we decide to conduct this study to evaluate the role and safety of single operator cholangioscopy (SOC) in the endoscopic treatment of post-LT biliary anastomotic strictures (AS). METHODS: Between March/2016 and June/2017, 20 consecutive patients referred for endoscopic treatment for biliary anastomotic stricture were included in this prospective observational cohort study. Inclusion criteria were age over 18 years old, and a deceased LT performed within at least 30 days. Exclusion criteria were non-anastomotic biliary stricture, biliary leakage, cast syndrome, any previous endoscopic therapy, pregnancy and inability to provide informed consent. All patients underwent SOC before endoscopic therapy with fully covered self-expandable metal stent (FCSEMS) and after stent removal. RESULTS: At pre-treatment SOC, stricture orifice and fibrotic changes could be visualized in all patients, vascular changes and surgical sutures in 60% and acute inflammatory changes in 30%. SOC was essential for guidewire placement in five cases. FCSEMS was successfully deployed in all patients. Stricture resolution rate was 44.4% (median stent indwelling 372 days). Stricture recurrence was 12.5% (median follow-up of 543 days). Adverse events were distal (66.6%) and proximal (5.5%) stent migration, stent occlusion (16.6%), severe abdominal pain (10%) and mild acute pancreatitis (10%). SOC was repeated after FCSEMS removal. Post-treatment SOC showed fibrotic changes in all but one patient; vascular and acute inflammatory changes were less frequent in comparison to index procedure. The disappearance of suture material was remarkable. None of the cholangioscopic findings were statistically correlated to treatment outcome or stricture recurrence. CONCLUSION: Endoscopic retrograde cholangiography with SOC is feasible in post-LT patients with AS. Cholangioscopic findings can be classified into fibrotic, vascular and acute inflammatory changes. Cholangioscopy may be helpful to assist guidewire passage, but Its overall role for changing management is post-LT patients was not demonstrated.
RESUMO CONTEXTO: As complicações biliares continuam sendo uma das principais causas de morbidade e perda do enxerto após o transplante hepático. O tratamento endoscópico das complicações biliares provou ser eficaz ao longo do tempo, deixando o tratamento cirúrgico restrito a casos de exceção. No entanto, ainda não podemos prever quais pacientes terão maior potencial de se beneficiar da terapia endoscópica. OBJETIVO: Nesta premissa, decidimos realizar este estudo para avaliar o papel e a segurança da colangioscopia peroral de operador único (CPO) no tratamento endoscópico das estenoses anastomóticas biliares (EA) pós-transplante hepático. MÉTODOS: Entre março de 2016 e junho de 2017, 20 pacientes consecutivos encaminhados para tratamento endoscópico da EA biliar foram incluídos neste estudo prospectivo de coorte observacional. Os critérios de inclusão foram idade superior a 18 anos e um transplante hepático de doador falecido realizado há pelo menos 30 dias. Pacientes com estenose biliar não anastomótica, fístula biliar, "cast" síndrome, qualquer terapia endoscópica prévia, gravidez e incapacidade de fornecer consentimento informado foram excluídos. Todos os pacientes foram submetidos à CPO antes da terapia endoscópica com prótese metálica autoexpansível totalmente coberta (PMAEC) e após a sua remoção. RESULTADOS: Na CPO realizada antes do tratamento endoscópico, o orifício de estenose e alterações fibróticas foram visualizadas em todos os pacientes, alterações vasculares e a presença de suturas cirúrgicas em 60%, enquanto alterações inflamatórias agudas em 30%. A CPO foi determinante para a transposição do fio-guia através da estenose em cinco casos. Uma PMAEC foi implantada com sucesso em todos os pacientes. A taxa de resolução da estenose foi de 44,4% (tempo médio de permanência de 372 dias). A recorrência da EA foi de 12,5% (acompanhamento médio de 543 dias). Os eventos adversos foram migração distal (66,6%) e proximal (5,5%) da prótese metálica, oclusão da PMAEC (16,6%), dor abdominal intensa (10%) e pancreatite aguda leve (10%). A CPO foi repetida após a remoção da PMAEC. A colangioscopia realizada após o tratamento endoscópico mostrou alterações fibróticas em todos, exceto em um paciente; alterações vasculares e inflamatórias agudas foram menos frequentes em comparação à CPO inicial. O desaparecimento do material de sutura, observado em todos os casos, foi notável. Nenhum dos achados colangioscópicos foram estatisticamente correlacionados ao resultado do tratamento ou à recorrência de estenose. CONCLUSÃO: A colangioscopia peroral é viável nos pacientes pós-transplante hepático com estenose biliar anastomótica. Os achados colangioscópicos podem ser classificados em alterações inflamatórias agudas, fibróticas e vasculares. A colangioscopia pode ser útil para auxiliar na passagem do fio-guia, mas seu papel geral na mudança de tratamento nos pacientes pós-transplante hepático não foi demonstrado.
