ABSTRACT

Introducción. Las malformaciones linfáticas quísticas, también llamadas linfangiomas quísticos, aparecen muy raramente de forma aislada en el hígado. Casos clínicos. Se presentan dos pacientes femeninas de edad preescolar con marcada hepatomegalia, dependiente de lesiones quísticas multitabicadas, secundarias a malformación linfática quística gigante del hígado, que fueron tratadas en el Hospital Pediátrico Universitario William Soler, La Habana, Cuba. Resultados. En ambos casos el diagnóstico se apoyó en los estudios de imágenes, la laparoscopia y el análisis histopatológico. En un caso el tratamiento fue la hepatectomía derecha, mientras que en el otro se empleó la escleroterapia, ambas con evolución favorable. Conclusión. A pesar de su rareza, este diagnóstico no debe obviarse ante un paciente pediátrico con lesiones hepáticas quísticas. El tratamiento de elección es la resección quirúrgica, pero su indicación y envergadura debe valorarse de forma individualizada


Introduction. Cystic lymphatic malformations, also called cystic lymphangiomas, are very rarely found in the liver. Clinical cases. Two pediatric female preschool-age patients. presented with hepatomegaly due to multi-septated cystic lesions of the liver, who received treatment at Hospital Pediátrico Universitario William Soler, La Habana, Cuba. Results. We report two pediatric cases with giant cystic lymphatic malformation of the liver. In both cases, the diagnosis were based on imaging, laparoscopy and pathology. In one case the treatment was right hepatectomy, whereas in the other, sclerotherapy was performed, both with a favorable outcome. Conclusion. Despite its rarity, this diagnosis should be considered in pediatric patients with hepatic cystic lesions. The recommended treatment is surgical resection, but its indication and extent should be assessed individually for each patient.

ABSTRACT

Lograr determinar el volumen total de un hígado (VHT), o volumetría hepática, pasa a ser de relevancia en diversas situaciones, tales como, vigilancia del progreso de una enfermedad de carácter crónico, planificación de resecciones y trasplantes hepáticos; y observación del clearance hepático de algunos fármacos hepatotropos. La VHT se puede realizar utilizando métodos de segmentación en el curso de una tomografía computarizada (TC), ya sean estos manual, automáticos, y semiautomáticos; mediante resonancia nuclear (RN), utilizando softwares de distintas generaciones (1ª a 4ª). La medición de VHT está indicada en pacientes sometidos a resecciones hepáticas mayores, en el contexto del tratamiento de neoplasias (carcinoma hepatocelular, colangiocarcinoma, metástasis hepáticas o tumores benignos de gran tamaño), abscesos (piogénicos, amebianos), y después de un traumatismo hepático complejo; así como también en la etapa preoperatoria de un trasplante hepático. El objetivo de este manuscrito fue generar un documento de estudio sobre métodos para determinar volumetría hepática.


SUMMARY: Being able to determine the total hepatic volume (THV), or THV, becomes relevant in various situations, such as monitoring the progress of a chronic disease, planning resections and liver transplants; and observation of the hepatic clearance of some hepatotropic drugs. THV can be performed using segmentation methods in the course of a computed tomography (CT), whether manual, automatic, or semi-automated; by nuclear resonance (NR), using software from different generations (1st to 4st). THV measurement is indicated in patients undergoing major liver resections, in the context of treatment of neoplasms (hepatocellular carcinoma, cholangiocarcinoma, liver metastases or large benign tumors), abscesses (pyogenic, amoebic), and after liver trauma complex, as well as in the preoperative stage of a liver transplant. The aim of this manuscript was to generate a study document regarding methods for determine hepatic volumetry.

ABSTRACT

Introducción. La neoplasia colorrectal es una patología oncológica muy frecuente a nivel mundial y una de las causas más comunes de mortalidad por cáncer. La epidemiologia, diagnóstico y tratamiento han sido ampliamente estudiadas, mientras que los datos sobre la enfermedad metastásica siguen siendo escasos. El hígado es el órgano más comúnmente afectado y algunos estudios sugieren diferencias en sobrevida y resecabilidad según la localización del tumor primario. El objetivo de este estudio fue establecer el comportamiento y resecabilidad de neoplasias avanzadas colorrectales en dos hospitales de la ciudad de Medellín, Colombia. Métodos. Estudio analítico retrospectivo para identificar los patrones de las metástasis hepáticas y sus características en función de las diferencias clínicas, histológicas y endoscópicas del tumor colorrectal primario entre 2015 y 2020. Resultados. Se recolectaron 54 pacientes con neoplasia colorrectal y metástasis hepáticas, 21 (39 %) derechas y 33 (61 %) izquierdas. El número de metástasis promedio fue de 3,1 en tumores del lado derecho y de 2,4 del izquierdo y el tamaño promedio de cada lesión fue de 4,9 y 4,2 cm, respectivamente. La tasa de resecabilidad fue del 42 % en los tumores derechos y del 82 % en los izquierdos. Las lesiones metacrónicas presentaron una tasa de resecabilidad del 90 % y las sincrónicas del 61 %. Conclusión. En este estudio, las lesiones originadas en neoplasias primarias del colon izquierdo y las lesiones metacrónicas fueron factores pronósticos favorables para la resecabilidad, un factor que impacta en la sobrevida y el tiempo libre de enfermedad de estos pacientes.


Introduction. Colorectal tumor is the most frequent pathology worldwide and one of the most common causes of mortality attributed to cancer. Epidemiology, diagnosis and treatment have been extensively studied, while information on metastatic disease remains scarce, despite being the main cause of death. Some studies suggest differences in terms of survival and resectability according to the anatomical location of the primary tumor. The aim is to establish the behavior and resectability of advanced cancers in two high-complex hospitals in the city of Medellín, Colombia. Methods. Cross-sectional observational study from secondary sources of information based on a retrospective cohort, using available data from adult patients with colorectal cancer and liver metastases between 2015 and 2020. Results. Fifty-four patients with colorectal neoplasms and liver metastases were collected, of which 21 (39%) were on the right side. The average number of liver metastases was 3.1 on the right side and 2.4 on the left, and the average size of each metastatic lesion was 4.9 cm and 4.2 cm, respectively. The resectability rate was 42% in the right tumors and 82% in the left ones. Metachronous lesions had a resectability rate of 90% and synchronous ones 61%. Conclusion. The complete resectability of liver metastatic lesions is the only therapeutic alternative with impact, in terms of survival and disease-free time in these patients. The favorable prognostic factors for the resectability of these lesions in our study were those originating from left primary tumors and metachronous lesions, where less liver tumor involvement was evidenced

ABSTRACT

RESUMEN Antecedentes : las ventajas de la hepatectomía videolaparoscópica (HVL) hicieron que gane cada vez más campo para el tratamiento de los tumores hepáticos benignos (THB). Objetivo : comparar los resultados perioperatorios de pacientes sometidos a HVL con los de los operados con hepatectomía abierta (HA) por THB, emparejados con propensity score matching (PSM). Material y métodos : estudio descriptivo, retrospectivo y comparativo de HA y HVL por THB entre agosto de 2010 y junio de 2021. Se analizaron variables demográficas, preoperatorias, intraoperatorias y posoperatorias. Para evitar sesgos de las distintas covariables entre los grupos se realizó un PSM 1:1. Resultados : de 403 hepatectomías, se analizaron 82 por THB. De ellas 36 (44%) fueron HA y 46 (56%) HVL. Edad media 45 ±14 años, 65% mujeres. Tras realizar el PSM, quedaron dos grupos de 28 pacientes cada uno. En HA, 5 (18%) pacientes requirieron transfusiones y ninguno en HVL (p = 0,01). Las complicaciones mayores se presentaron en 4 (14%) pacientes en HA, y ninguna en HVL (p = 0,03). Se reoperaron 4 (14%) pacientes con HA y ningún paciente con HVL (p = 0,03). La estadía hospitalaria total fue significativamente mayor en las HA (p = 0,04). No se registraron muertes a los 90 días en ninguno de los dos grupos. Conclusión : la HVL por THB es una técnica segura y eficaz, ya que los pacientes presentaron menor requerimiento transfusional, número de reoperaciones, de complicaciones mayores y de estadía hospitalaria que con HA. Por las ventajas encontradas, la HVL podría ser considerada la técnica de elección en cirugía por THB.


ABSTRACT Background : The advantages of laparoscopic liver resection (LLR) have increased its use for the treatment of benign liver tumors (BLTs). Objective : The aim of this study was to compare the perioperative outcomes of patients undergoing LLR with those operated on with open liver resection (OLR) for BLTs using propensity score matching (PSM). Material and methods : We conducted a descriptive and retrospective study comparing OLRs with LLRs performed between August 2010 and June 2021. The demographic, perioperative, intraoperative and postoperative variables were analyzed. We used PSM with 1:1 matching to avoid biases of the different covariates between the groups. Results : Of 303 liver resections, 82 corresponded to BLTs and were included in the analysis; 36 (44%) were OLRs and 46 (56%) were LLRs. Mean age was 45 ±14 years and 65% were women. After PSM, two groups of 28 patients each were constituted. Five patients (18%) in the OLR group and none in the LLR required transfusions (p = 0.01). Major complications, occurred in 4 (14%) patients in the OLR group and in no cases in the LLR group (p = 0.03). Four (14%) undergoing OLR required reoperation versus no patients with LLR (p = 0.03). Total length of hospital stay was significantly longer in OLR (p = 0.04). There were no deaths in any of the groups within 90 days. Conclusion : LLR for BLTs is a safe and effective technique, with lower requirement for transfusions, fewer reoperations and major complications and shorter length of hospital stay than OLR, Therefore, LLR could be considered the surgical technique of choice for BLTs.

ABSTRACT

Introducción. Las neoplasias quísticas mucinosas del hígado son tumores poco frecuentes, equivalen a menos del 5 % de todas las lesiones quísticas hepáticas y se originan generalmente en la vía biliar intrahepática, con poco compromiso extrahepático. En la mayoría de los casos su diagnóstico es incidental dado que es una entidad generalmente asintomática con un curso benigno; sin embargo, hasta en el 30 % pueden ser malignas. En todos los casos se debe hacer una resección quirúrgica completa de la lesión. Caso clínico. Se presentan dos pacientes con diagnóstico de neoplasia quística mucinosa en la vía biliar intrahepática, así como sus manifestaciones clínicas, hallazgos imagenológicos y tratamiento. Discusión. Debido a su baja incidencia, esta patología constituye un reto diagnóstico, que se puede confundir con otro tipo de entidades más comunes. El diagnóstico definitivo se hace de forma histopatológica, pero en todos los casos, ante la sospecha clínica, se recomienda la resección completa. Conclusión. Se presentan dos pacientes con diagnóstico de neoplasias quísticas mucinosas del hígado, una entidad poco frecuente y de difícil diagnóstico


Introduction. Mucinous cystic neoplasms of the liver are rare tumors, accounting for less than 5% of all liver cystic lesions, and generally originate from the intrahepatic bile duct with little extrahepatic involvement. In most cases its diagnosis is incidental since it is a generally asymptomatic entity with a benign course; however, up to 30% can have a malignant course. In all cases, complete surgical resection of the lesion must be performed. Clinical case. Two patients with a diagnosis of mucinous cystic neoplasm in the intrahepatic bile duct are presented, as well as their clinical manifestations, imaging findings, and treatment. Discussion. Due to its low incidence, this pathology constitutes a diagnostic challenge, which can be confused with other types of more common entities. The definitive diagnosis is made histopathologically, but in all cases, given clinical suspicion, complete resection is recommended. Conclusion. Two patients with a diagnosis of mucinous cystic neoplasms of the liver are presented, a rare entity that is difficult to diagnose

ABSTRACT

ABSTRACT BACKGROUND: Morbidity of liver resections is related to intraoperative bleeding and postoperative biliary fistulas. The Endo-GIA stapler (EG) in liver resections is well established, but its cost is high, limiting its use. The linear cutting stapler (LCS) is a lower cost device. AIMS: To report open liver resections, using LCS for transection of the liver parenchyma and en bloc stapling of vessels and bile ducts. METHODS: Ten patients were included in the study. Four patients with severe abdominal pain had benign liver tumors (three adenomas and one focal nodular hyperplasia). Among the remaining six patients, four underwent liver resection for the treatment of colorectal liver metastases, three of which had undergone preoperative chemotherapy. The other two cases were one patient with metastasis from a testicular teratoma and the other with metastasis from a gastrointestinal neuroectodermal tumor. RESULTS: The average length of stay was five days (range 4-7 days). Of the seven patients who underwent resections of segments II/III, two presented postoperative complications: one developed a seroma and the other a collection of abdominal fluid who underwent percutaneous drainage, antibiotic therapy, and blood transfusion. Furthermore, the three patients who underwent major resections had postoperative complications: two developed anemia and received blood transfusions and one had biloma and underwent percutaneous drainage and antibiotic therapy. CONCLUSIONS: The use of the linear stapler in hepatectomies was efficient and at lower costs, making it suitable for use whenever EG is not available. The size of the LCS stapler shaft is more suitable for en bloc transection of the left lateral segment of the liver, which is thinner than the right one. Further studies are needed to evaluate the safety of LCS for large liver resections and resections of tumors located in the right hepatic lobe.


RESUMO RACIONAL: A morbidade das ressecções hepáticas está relacionada a sangramento intraoperatório e fístulas biliares pós-operatórias. O grampeador Endo-GIA (EG) em ressecções hepáticas está bem estabelecido, mas o seu custo é elevado, limitando seu uso. O grampeador de corte linear (LCS) é um dispositivo com menor custo. OBJETIVOS: Relatar ressecções hepáticas abertas, empregando o LCS para transecção do parênquima hepático e grampeamento em bloco de vasos e ductos biliares. MÉTODOS: Dez pacientes foram incluídos no estudo. Quatro pacientes com dor abdominal importante apresentavam tumores hepáticos benignos (três adenomas e um hiperplasia nodular focal). Dentre os demais seis pacientes, quatro foram submetidos à ressecção hepática para o tratamento de metástases hepáticas colorretais, sendo que três deles haviam sido submetidos à quimioterapia pré-operatória. Os dois outros casos foram um paciente com metástase de teratoma testicular e o outro com metástase de tumor neuroectodérmico gastrointestinal. RESULTADOS: O tempo médio de internação foi de 5 dias (variação=4-7 dias). Dos sete pacientes submetidos a ressecções dos segmentos II/III, dois apresentaram complicações pós-operatórias: um paciente desenvolveu seroma e o outro uma coleção de fluido abdominal submetido a drenagem percutânea, antibioticoterapia e transfusão de sangue. Além disso, os três pacientes submetidos a ressecções maiores tiveram complicações pós-operatórias: dois pacientes desenvolveram anemia e receberam transfusões de sangue e um paciente apresentou biloma e foi submetido a drenagem percutânea e antibioticoterapia. CONCLUSÕES: O emprego do grampeador linear nas hepatectomias foi eficiente e a custos mais baixos, tornando-o adequado para uso sempre que EG não estiver disponível O tamanho da haste do grampeador LCS é mais adequado para a transecção em bloco do segmento lateral esquerdo do fígado, que é mais fino que o direito. Novos estudos são necessários para avaliar a segurança do LCS para grandes ressecções hepáticas e ressecções de tumores localizados no lobo hepático direito.

ABSTRACT

Las modernas técnicas quirúrgicas y anestésicas han permitido ampliar el número de intervenciones quirúrgicas a nivel hepático por diversas patologías. Logrando disminuir su moralidad pero manteniendo al día de hoy elevados niveles de morbilidad. Durante la cirugía hepática se producen cambios hemodinámicos vinculados a la movilización del hígado, a los clampeos y a las pérdidas sanguíneas independientemente de la vía de abordaje. En el postoperatorio las complicaciones o cambios fisiopatológicos derivan de las lesiones producidas por los fenómenos de isquemia y reperfusión; y aquellas producidas por la regeneración hepática. Dicha capacidad depende no solo de la cantidad de hígado remanente sino también de la posible hepatopatía preexistente. La insuficiencia hepática postoperatoria es la complicación más temida y se manifiesta con ictericia, ascitis, encefalopatía y alteraciones en la paraclínica como la hiperbilirrubinemia y descenso del tiempo de protrombina. Las complicaciones quirúrgicas dependen del procedimiento realizado y se dividen principalmente en biliares y vasculares. Las secuelas de las hepatectomías dependen de factores como el estado general del paciente, la presencia hepatopatía, el acto quirúrgico y la cantidad y calidad del hígado remanente.


Modern surgical and anesthetic techniques have made it possible to increase the number of liver surgeries for various pathologies. This has reduced morbidity but still maintains high levels of morbidity. During hepatic surgery, hemodynamic changes related to liver mobilization, clamping and blood loss occur independently of the approach route. In the postoperative period, complications or pathophysiological changes derive from the lesions produced by ischemia and reperfusion phenomena; and those produced by hepatic regeneration. This capacity depends not only on the amount of remaining liver but also on the possible pre-existing hepatopathy. Postoperative liver failure is the most feared complication and manifests with jaundice, ascites, encephalopathy and paraclinical alterations such as hyperbilirubinemia and decreased prothrombin time. Surgical complications depend on the procedure performed and are mainly divided into biliary and vascular. The sequelae of hepatectomies depend on factors such as the patient's general condition, the presence of liver disease, the surgical procedure and the quantity and quality of the remaining liver.


As modernas técnicas cirúrgicas e anestésicas tornaram possível aumentar o número de cirurgias hepáticas para várias patologias. Isto levou a uma diminuição da morbidade, mas ainda mantém altos níveis de morbidade. Durante a cirurgia hepática, ocorrem alterações hemodinâmicas ligadas à mobilização hepática, pinçamento e perda de sangue, independentemente da via de aproximação. No período pós-operatório, complicações ou alterações fisiopatológicas derivam de lesões causadas por fenômenos de isquemia e reperfusão, e aquelas causadas pela regeneração hepática. Esta capacidade depende não apenas da quantidade de fígado restante, mas também de uma possível doença hepática pré-existente. A insuficiência hepática pós-operatória é a complicação mais temida e se manifesta com icterícia, ascite, encefalopatia e alterações paraclínicas, tais como hiperbilirrubinemia e diminuição do tempo de protrombina. As complicações cirúrgicas dependem do procedimento realizado e são divididas principalmente em biliares e vasculares. As seqüelas de hepatectomias dependem de fatores como o estado geral do paciente, a presença de doença hepática, o procedimento cirúrgico e a quantidade e qualidade do fígado restante.

ABSTRACT

La resección quirúrgica con márgenes negativos de las metástasis hepáticas de cáncer colorectal, representa la única opción de tratamiento con potencial curativo, sin embargo, el 85% de estos pacientes son considerados irresecables a la evaluación inicial, ya sea por número, tamaño y localización de las metástasis o por un remanente hepático futuro insuficiente. ALPPS es una técnica quirúrgica compleja, que permite en dos tiempos operatorios, la resección de extensas porciones de parénquima hepático tras un periodo de incremento volumétrico del remanente, que alcanza el 80% en un periodo de 9 días, lo que supera ampliamente a otras técnicas como la embolización/ligadura portal preoperatoria. Pese a cuestionamientos iniciales relativos a la morbimortalidad asociada, la significativa ganancia de masa hepatocelular lograda con ALPPS, ha permitido el tratamiento exitoso de pacientes con alta carga tumoral metastásica hepática, tensionando principios fundamentales clásicamente considerados para la realización de hepatectomías mayores en forma segura. El objetivo de este trabajo es presentar la experiencia inicial con la aplicación de la técnica de ALPPS llevado al extremo de dejar un remanente hepático constituido por un único segmento.


R0 resection of colorectal liver metastases is the main curative treatment option; however, 85% of patients are considered initially unresectable, either due to number, size and location of metastases or insufficient future liver remnant. ALPPS is a complex surgical technique, which allows, in two operative times, the resection of extensive portions of liver parenchyma after a period of volumetric remnant increase, which reaches 80% in 9 days, far exceeding other techniques as well as preoperative portal embolization / ligation. Despite initial doubts regarding the associated morbidity and mortality, the significant gain in hepatocellular mass achieved with ALPPS has allowed the successful treatment of patients with high hepatic metastatic tumor burden, questioning fundamental principles classically considered for safely performing major hepatectomies. The aim of this article is to show the initial experience with the ALPPS technique application taken to the extreme of leaving a liver remnant made up of a single segment.

ABSTRACT

El tratamiento del hemangioma hepático gigante (HHG), sigue siendo motivo de controversia. El objetivo de este estudio fue reportar los resultados de pacientes con HHG resecados quirúrgicamente en términos de morbilidad postoperatoria (MPO). Serie de casos con seguimiento. Se incluyeron pacientes con HHG, sometidos a cirugía de forma consecutiva, en Clínica RedSalud Mayor, entre 2011 y 2020. La variable resultado fue MPO. Otras variables de interés fueron: tiempo quirúrgico, estancia hospitalaria y mortalidad. Las pacientes fueron seguidas de forma clínica. Se utilizó estadística descriptiva, con medidas de tendencia central y dispersión. Se intervinieron 5 pacientes, con una mediana de edad de 38 años. La medianas del tiempo quirúrgico y estancia hospitalaria; fueron 75 min y 4 días respectivamente. La MPO fue 20 % (1 caso de seroma). Con una mediana de seguimiento de 41 meses, los pacientes se encuentran asintomáticos y no se ha verificado morbilidad alejada. La resección quirúrgica de un HHG se puede realizar con escasa morbilidad, tanto en términos numéricos como de gravedad de la complicación observada.


SUMMARY: Treatment of giant hepatic hemangioma (GHH) remains controversial. The aim of this study was to report the outcomes of surgically resected GHH patients in terms of postoperative morbidity (POM). Case series with follow-up. Patients with GHH who underwent surgery consecutively at the RedSalud Mayor Clinic between 2011 and 2020 were included. The outcome variable was POM. Other variables of interest were surgical time, hospital stay and mortality. The patients were followed up clinically. Descriptive statistics were used, with measures of central tendency and dispersion. Five patients underwent surgery, with a median age of 38 years. The median surgical time and hospital stay; were 75 min and 4 days respectively. The MPO was 20 % (1 case of seroma). With a median follow-up of 41 months, the patients are asymptomatic, and no distant morbidity has been verified. Surgical resection of GHH can be performed with low morbidity, both in terms of numbers and the severity of the complication observed.

ABSTRACT

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.

ABSTRACT

ABSTRACT - BACKGROUND: Colorectal cancer generally metastasizes to the liver. Surgical resection of liver metastasis, which is associated with systemic chemotherapy, is potentially curative, but many patients will present recurrence. In selected patients, repeated hepatectomy is feasible and improves overall survival. AIM: This study aimed to analyze patients with colorectal liver metastasis (CRLM) submitted to hepatectomy in three centers from Rio de Janeiro, over the past 10 years, by comparing the morbidity of first hepatectomy and re-hepatectomy. METHODS: From June 2009 to July 2020, 192 patients with CRLM underwent liver resection with curative intent in three hospitals from Rio de Janeiro Federal Health System. The data from patients, surgeries, and outcomes were collected from a prospectively maintained database. Patients submitted to first and re-hepatectomies were classified as Group 1 and Group 2, respectively. Data from groups were compared and value of p<0.05 was considered significant. RESULTS: Among 192 patients, 16 were excluded. Of the remaining 176 patients, 148 were included in Group 1 and 28 were included in Group 2. Fifty-five (37.2%) patients in Group 1 and 13 (46.5%) in Group 2 presented postoperative complications. Comparing Groups 1 and 2, we found no statistical difference between the cases of postoperative complications (p=0.834), number of minor (p=0.266) or major (p=0.695) complications, and deaths (p=0.407). CONCLUSIONS: No differences were recorded in morbidity or mortality between patients submitted to first and re-hepatectomies for CRLM, which reinforces that re-hepatectomy can be performed with outcomes comparable to first hepatectomy.


RESUMO - RACIONAL: O câncer colorretal geralmente metastatiza para o fígado. Hepatectomia associada à quimioterapia sistêmica é potencialmente curativa para metástases hepáticas colorretais, entretanto, muitos pacientes apresentarão recidiva após a cirurgia. Em casos selecionados, a re-hepatectomia é viável, com relatos de melhora na sobrevida global. OBJETIVO: Analisar pacientes com metástase hepática colorretal operados em três centros do Rio de Janeiro, nos últimos 10 anos, comparando as morbidades da primeira hepatectomia e da re-hepectomia. MÉTODOS: De junho de 2009 a julho de 2020, 192 pacientes com metástase hepática colorretal foram submetidos à hepatectomia em três hospitais do Rio de Janeiro. Os dados dos pacientes, cirurgias e desfechos foram coletados de um banco de dados mantido prospectivamente. Pacientes submetidos à primeira hepatectomia e re-hepatectomia foram classificados como Grupo 1 e Grupo 2, respectivamente. Os dados dos grupos foram comparados e o valor de p<0,05 foi considerado significativo. RESULTADOS: Dentre 192 pacientes, dezesseis foram excluídos. Dos 176 pacientes restantes, 148 e 28 foram incluídos dos Grupos 1 e 2, respectivamente. Cinquenta e cinco (37,2%) pacientes no Grupo 1 e treze (46,5%) no Grupo 2 apresentaram complicações pós-operatórias. Comparando os Grupos 1 e 2, não foi observada diferença estatística entre o número de pacientes com complicações pós-operatórias (p = 0,834), complicações menores (p = 0,266) ou maiores (p = 0,695) e óbitos (p = 0,407). CONCLUSÕES: Não foram registradas diferenças na morbidade ou mortalidade entre os pacientes submetidos à primeira ou à re-hepatectomia em pacientes com metástase hepática colorretal, o que sustenta que a re-hepatectomia pode ser realizada com resultados comparáveis à primeira hepatectomia.

ABSTRACT

Introdução: O trabalho objetiva avaliar o perfil epidemiológico dos pacientes operados por adenoma hepático e os fatores de influência nas diferentes apresentações clínicas. Métodos: Estudo transversal descritivo com 21 pacientes operados por adenoma hepático. Dados de prontuário e laudos anatomopatológicos foram revisados a fim de estudar a relação entre perfil dos pacientes, apresentação clínica e características do tumor. Resultados: Sexo feminino foi predominante na amostra. A idade média dos pacientes foi de 32 anos e o IMC médio 25,9. Uso de anticoncepcional oral foi relatado em 93% dos casos, sendo 13 anos o tempo médio de uso. A presença de comorbidades teve associação com adenomas de maior tamanho, e diabetes mellitus foi doença mais frequente associada a este tumor. Houve associação clínica entre tamanho do adenoma e sintomatologia: pacientes com sinais e sintomas mais pronunciados apresentaram lesões de tamanho médio superior em comparação aos pacientes com sintomas inespecíficos ou ausentes. Conclusão: Os fatores já conhecidos associados ao Adenoma Hepático envolvem o sexo feminino, uso de contraceptivo oral de longa data, doenças do armazenamento do glicogênio, uso de anabolizantes e, menos comumente, gestação e diabetes mellitus. Neste trabalho evidenciamos o diabetes mellitus como a comorbidade mais frequente entre os pacientes com diagnóstico de Adenoma Hepático, relacionando-se a adenomas de maior tamanho na amostra deste estudo, o que sugere possível associação do diabetes mellitus na gênese dos adenomas hepáticos e também no prognóstico, visto que lesões maiores representam risco aumentado de complicações.


Introduction: This work aims to evaluate the epidemiological profile of patients who underwent surgery for liver adenoma and the factors that could influence different clinical presentations. Methods: Descriptive cross-sectional study with 21 patients with liver adenoma who underwent surgery. Medical records and pathological reports were reviewed to study the connection between patients' profile, clinical presentation, and features of the tumor. Results: Female sex predominated in the sample. The mean age of patients was 32 years and the mean BMI was 25.9. The use of oral contraceptives was reported in 93% of the cases, with an average usage time of 13 years. The presence of comorbidities was associated with larger adenomas, and diabetes mellitus was the most frequent comorbidity co-existing with this tumor. Clinical association between the size of adenomas and symptoms was identified: patients with more pronounced signs and symptoms had larger lesions compared with patients with nonspecific or absent symptoms. Conclusion: The known factors associated with Hepatic Adenoma involve female sex, long-term use of oral contraceptives, glycogen storage diseases, use of anabolic steroids, and, less commonly, pregnancy and diabetes mellitus. In this study, we highlight diabetes mellitus as the most frequent comorbidity among patients diagnosed with Hepatic Adenoma, relating to larger adenomas in this study sample, which suggests a possible association of diabetes mellitus in the genesis of liver adenomas and in the prognosis, since larger lesions represent an increased risk of complications.

ABSTRACT

ABSTRACT Introduction: liver tumors are rare neoplasms in childhood (1-2%), and about 2/3 are malignant. Hepatoblastoma (HB) is the most frequent, followed by hepatocellular carcinoma (HCC). In both, the main treatment is surgical resection. Currently, chemotherapy and liver transplantation have improved outcomes. Objective: study of the epidemiological profile and evolution of liver cancer cases in a referral pediatric hospital. Methodology: a retrospective survey of medical records of patients aged up to 18 years with a diagnosis of primary malignant hepatic neoplasm between 2012 and 2020, carried out in the largest exclusively pediatric hospital in Brazil. Results: a total of 13 patients with malignant liver tumors (HB 12, HCC 1) were treated. Of the HB cases, 66,7% were male, with a mean age of 2 years and the main alteration in the palpable abdominal mass. Tumors involved an average of 3 liver segments, more in the right lobe (54%). Only one patient was treated with surgery without neoadjuvant therapy, another one underwent transplantation like the first treatment, and another 2 required liver transplantation as a rescue. The middle follow-up time of patients with HB was 39 months and only 1 case died due to febrile neutropenia. The 5-year overall and disease-free survival was 91.7% and 81.5%, respectively. Conclusion: Advanced staging at the time of diagnosis has always been a poor prognostic factor in patients with primary malignant liver tumors. However, the results and survival have improved with the advancement of chemotherapy, surgical technique, and liver transplantation.


RESUMO Introdução: tumores hepáticos são neoplasias raras na infância (1-2%), sendo que cerca de 2/3 são malignos. O hepatoblastoma (HB) é o mais frequente, seguido do carcinoma hepatocelular (CHC). Em ambos, o principal tratamento é a ressecção cirúrgica completa. Atualmente, a quimioterapia e o transplante hepático têm melhorado os resultados. Objetivo: estudo do perfil epidemiológico e evolução dos casos de cânceres hepáticos em um hospital pediátrico de referência. Método: Levantamento retrospectivo de prontuários de pacientes até 18 anos com diagnóstico de neoplasia maligna primária hepática entre 2012 e 2020 realizado no maior hospital exclusivamente pediátrico do Brasil. Resultados: foram atendidos 13 pacientes com tumores malignos hepáticos (HB 12, CHC 1). Dos casos de HB, 66,7% eram do sexo masculino, com idade média de 2 anos e a principal alteração foi massa abdominal palpável. Os tumores envolviam em média 3 segmentos hepáticos, mais em lobo direito (54%). Um paciente foi tratado com cirurgia sem neoadjuvância, um foi submetido a transplante inicialmente e outros 2 necessitaram de transplante hepático como resgate. O tempo de seguimento dos pacientes com HB foi de 39 meses e apenas 1 caso foi a óbito por neutropenia febril. A sobrevida geral e livre de doença em 5 anos foi de 91,7% e 81,5% respectivamente. Conclusão: o estadiamento avançado no momento do diagnóstico sempre foi um fator de mau prognóstico em pacientes com tumores hepáticos malignos primários. Entretanto, os resultados e a sobrevida têm melhorado significativamente com o avanço da quimioterapia, da técnica cirúrgica e do transplante hepático.

ABSTRACT

Mujer de 54 años sometida a colecistectomía laparoscópica programada por colecistolitiasis sintomática, el procedimiento fue convertido a abordaje abierto por presencia de bilirragia perioperatoria no localizada, tratada con sutura primaria del lecho vesicular bajo sospecha de un conducto aberrante de Luschka. Al vigésimo día postoperatorio se diagnostica una fístula biliar tras la aparición de bilirragia a través de la herida quirúrgica. Una colangiografía transhepática percutánea mostró una pérdida completa de continuidad con fuga a ese nivel, confirmando la lesión del conducto hepático derecho, con un extremo cortado retraído del conducto hepático. Debido a la compleja lesión de la vía biliar proximal, a los 3 meses de la primera cirugía se realiza una hepatectomía derecha. Aunque la hepatectomía no es un procedimiento estándar para pacientes con lesiones quirúrgicas de la via biliar, debe considerarse como parte del arsenal quirúrgico para la reparación de un grupo seleccionado de pacientes en lesiones postcolecistectomía


A 54-year-old female underwent a planned laparoscopic cholecystectomy due to a symptomatic cholecystolithiasis, the procedure was converted to an open approach due to the presence of a not located perioperative bilirhagia, treated with a primary suture of the gallbladder bed under the suspicion of an aberrant duct of Luschka. On the 20th postoperative day, the patient is diagnosed with a biliary fistula after the appearance of bilirhagia through the surgical wound. A percutaneous transhepatic cholangiography showed a complete loss of continuity with leakage at that level, confirming the right hepatic duct injury, with a retracted cut end from the hepatic duct. Due to the complex proximal bile duct injury, 3 months after the first surgery, a right hepatectomy is performed. Although an hepatectomy is not a standard procedure for patients with IBDI, it should be considered as a part of the surgical armamentarium for the repair of a selected group of patients in postcholecystectomy injuries

ABSTRACT

Introducción. La resección quirúrgica es el tratamiento de elección de las neoplasias primarias y secundarias del hígado. Los pacientes con hepatocarcinoma de los segmentos centrales representan un reto, siendo la hepatectomía extendida la técnica más usada, sin embargo, el riesgo postquirúrgico de falla hepática es alto, dado que la resección puede comprometer entre el 65 % y el 80 % del volumen hepático. La mesohepatectomía es una alternativa que permite dejar un volumen hepático residual suficiente. El objetivo de este trabajo es presentar nuestra experiencia en el tratamiento de pacientes con hepatocarcinomas en segmentos centrales a quienes se les realizó mesohepatectomía. Serie de casos. Se presentan tres pacientes no cirróticos, con hepatocarcinoma en los segmentos 4, 5 y 8, que fueron atendidos en el Hospital San Vicente Fundación, en las sedes de Medellín y de Rionegro, entre 2018 y 2020. Resultados. La mesohepatectomía se realizó mediante ligadura selectiva de los pedículos del segmento 4 y del sector anterior derecho. Se utilizó aspirador ultrasónico y endograpadora para la transección hepática. La duración de la maniobra de Pringle varió entre 16 y 43 minutos. El sangrado promedio fue de 1000 ml. Solo un paciente presentó fuga biliar tipo B. No hubo mortalidad a 30 días. Conclusiones. La mesohepatectomía es una alternativa segura para pacientes con tumores en los segmentos centrales, que permite disminuir el riesgo de falla hepática luego de la resección.


Introduction. Surgical resection is the treatment of choice for primary and secondary neoplasms of the liver. Patients with central segment hepatocarcinoma represent a challenge, with extended hepatectomy being the most widely used technique. However, the postsurgical risk of liver failure is high since resection can compromise between 65% and 80% of liver volume. Mesohepatectomy is an alternative that allows a sufficient residual liver volume to be left. The objective of this work is to present treatment of patients with central segment hepatocarcinoma.Clinical cases. Three non-cirrhotic patients are presented, with hepatocarcinoma in segments 4, 5 and 8, who were treated at the San Vicente Fundación Hospital in Medellín and Rionegro, between 2018 and 2020.Results. Mesohepatectomy was performed by selective ligation of the pedicles of segment 4 and the right anterior sector. An ultrasonic aspirator and endostapler were used for liver transection. The duration of the Pringle ma-neuver ranged from 16 to 43 minutes. The average bleeding was 1000 cc. Only one patient had type B bile leakage. There was no 30-day mortality.Conclusions. Mesohepatectomy is a safe alternative for patients with tumors in the central segments, which reduces the risk of liver failure after resection.

ABSTRACT

ABSTRACT BACKGROUND: Robotic surgery has gained growing acceptance in recent years, expanding to liver resection. OBJECTIVE: The aim of this paper is to report the experience with our first fifty robotic liver resections. METHODS: This was a single-cohort, retrospective study. From May 2018 to December 2020, 50 consecutive patients underwent robotic liver resection in a single center. All patients with indication for minimally invasive liver resection underwent robotic hepatectomy. The indication for the use of minimally invasive technique followed practical guidelines based on the second international laparoscopic liver consensus conference. RESULTS: The proportion of robotic liver resection was 58.8% of all liver resections. Thirty women and 20 men with median age of 61 years underwent robotic liver resection. Forty-two patients were operated on for malignant diseases. Major liver resection was performed in 16 (32%) patients. Intrahepatic Glissonian approach was used in 28 patients for anatomical resection. In sixteen patients, the robotic liver resection was a redo hepatectomy. In 10 patients, previous liver resection was an open resection and in six it was minimally invasive resection. Simultaneous colon resection was done in three patients. One patient was converted to open resection. Two patients received blood transfusion. Four (8%) patients presented postoperative complications. No 90-day mortality was observed. CONCLUSION: The use of the robot for liver surgery allowed to perform increasingly difficult procedures with similar outcomes of less difficult liver resections.


RESUMO CONTEXTO: A cirurgia robótica tem tido aceitação crescente nos últimos anos, expandindo-se para a ressecção hepática. OBJETIVO: Relatar a experiência com as primeiras cinquenta ressecções hepáticas robóticas. MÉTODOS: Trata-se de análise retrospectiva de dados coletados prospectivamente. De maio de 2018 a dezembro de 2020, 50 pacientes consecutivos foram submetidos à ressecção hepática robótica em um único centro. Todos os pacientes com indicação de ressecção hepática minimamente invasiva foram submetidos à hepatectomia robótica. A indicação de técnica minimamente invasiva seguiu as diretrizes práticas baseadas na segunda conferência internacional de consenso laparoscópico hepático. RESULTADOS: A proporção de ressecções hepáticas robóticas foi de 58,8% de todas as ressecções hepáticas. Trinta mulheres e 20 homens com idade mediana de 61 anos foram submetidos à ressecção hepática robótica. Quarenta e dois pacientes foram operados por doenças malignas. Ressecção hepática maior foi realizada em 16 (32%) pacientes. A abordagem Glissoniana intra-hepática foi usada em 28 pacientes para ressecção anatômica. Em 16 pacientes, a ressecção hepática robótica foi uma re-hepatectomia. Em 10, a hepatectomia prévia foi aberta e em seis foi por via minimamente invasiva. Ressecção simultânea do cólon foi feita em três pacientes. Um paciente foi convertido para ressecção aberta. Dois pacientes receberam transfusão sanguínea. Quatro (8%) pacientes apresentaram complicações pós-operatórias. Mortalidade em 90 dias foi nula. CONCLUSÃO: O uso do robô permitiu realizar procedimentos progressivamente mais complexos com resultados semelhantes às hepatectomias menos complexas.

ABSTRACT

Low-level laser therapy has several biological effects; one of them is tissue regeneration. Recent studies have been held on the application of laser therapy on the liver of rats after partial hepatectomy to promote liver regeneration. The aim of this article was to review the recent studies on the effects of low-level laser therapy on rat liver regeneration after partial hepatectomy and the laser parameters used in those studies. A review of recent relevant literature was performed in Pubmed, Scielo, Medline, and Bireme databases. Articles related to the application of low-level laser therapy on hepatic regeneration were included. Articles with hepatic regeneration in the presence of pathologies were not included. Nine studies were found matching the study criteria. In most studies, low-level laser therapy promoted liver regeneration after partial hepatectomy, without further damage to the remaining liver. Not all laser parameters required for the reproducibility of the study were described by all authors. The therapeutic use of low-level laser therapy in liver regeneration can be promising; however, since the liver is a vital organ, and the laser application is intraoperative, future studies are necessary. The parameters used must be properly described and standardized to allow the reproducibility of the study, in order to define a therapeutic window and thus, consider its clinical use. It is also essential to clarify the mechanisms by which laser promotes liver regeneration to guarantee its safety and therapeutic efficacy.


Laserterapia de baixa potência tem vários efeitos biológicos, sendo um deles a regeneração de tecido. Sua aplicação no fígado de ratos após hepatectomia parcial para promoção de regeneração hepática tem sido estudada recentemente. O objetivo deste artigo foi revisar os estudos recentes dos efeitos da laserterapia de baixa potência na regeneração de fígado de ratos após hepatectomia parcial de fígado e os parâmetros de laser empregados. Uma revisão da literatura relevante recente foi realizada nas bases de dados Pubmed, Scielo, Medline e Bireme. Artigos sobre a aplicação da laserterapia de baixa potência na regeneração de fígado foram incluídos. Artigos sobre regeneração hepática na presença de patologias foram excluídos. Nove estudos foram encontrados correspondendo aos critérios do estudo. Na maioria dos estudos, a laserterapia de baixa potência promoveu regeneração hepática após hepatectomia parcial, sem causar danos adicionais ao fígado remanescente. Não foram descritos todos os parâmetros necessários para reprodutibilidade dos estudos por todos os autores. O uso terapêutico da laserterapia de baixa potência na regeneração de fígado pode ser promissor, entretanto, como o fígado é um órgão vital e a aplicação do laser é intraoperativa, estudos futuros são necessários, assim como os parâmetros da aplicação de laser precisam ser descritos apropriadamente e padronizados, para permitir a reprodutibilidade do estudo, para que uma janela terapêutica possa ser definida e seu uso clínico possa ser considerado. Também é essencial esclarecer através de quais mecanismos o laser promove regeneração de fígado para garantir sua segurança e eficácia terapêutica.

ABSTRACT

RESUMEN Desde la aparición de un programa de Fast Track en cirugía colónica con resultados alentadores, muchos centros se abocaron a su aplicación y mejoramiento. El uso de estos programas en diferentes órganos trajo aparejados los mismos resultados que en cirugía colónica. Las resecciones hepáticas no quedaron excluidas de su uso. En ellas se logró una importante reducción de los días de estancia hospitalaria y de los costos. Entre los puntos que componen estos programas, una adecuada información al paciente y un compromiso de parte de este, la analgesia multimodal, la fluidoterapia y un inicio temprano de la alimentación parecen ser los más importantes.


ABSTRACT Since the development of fast-track programs in colorectal surgery with promising results, many centers started with these programs, and improved them. These programs were applied to different organs with the same results observed in colorectal surgery. Liver resections were not excluded from enhanced recovery programs, with a significant reduction in length of hospital stay and costs. Adequate patient information and commitment, multimodal analgesia, fluid therapy and early oral intake are the most important items of these programs.

ABSTRACT

RESUMEN Antecedentes: La cirugía hepática videolaparoscópica ha experimentado un importante desarrollo; sin embargo, la mayoría de las hepatectomías continúan haciéndose por vía convencional. Objetivo: presentar la experiencia y aplicabilidad de hepatectomías videolaparoscópicas. Material y métodos: análisis retrospectivo de pacientes sometidos a una hepatectomía entre agosto de 2010 y diciembre de 2019. Analizamos variables preoperatorias, intraoperatorias y posoperatorias. Para evaluar la aplicabilidad, se dividió la muestra en: Etapa 1: agosto de 2010 a diciembre de 2013; Etapa 2: enero de 2014 a diciembre de 2016, Etapa 3: enero de 2017 a diciembre de 2019. Resultados: de 385 hepatectomías realizadas, 119 fueron videolaparoscópicas: 53 (44%) fueron to talmente laparoscópicas, 64 (54%) mano-asistidas y 2 híbridas. La aplicabilidad global fue 31%. En la etapa 1: 23% , en la 2: 30% y en la 3: 44% (p < 0,05). Fueron patología maligna en la etapa 1: 36%, en la 2: 67% y en la 3: 72% (p < 0,05). Hepatectomías mayores: 13%, 31% y 32% en etapas 1, 2, y 3, respectivamente (p < 0,05). El índice de conversión fue 12%, 0% y 11%, respectivamente (p NS). Se utilizó clampeo pedicular en: 6%, 5% y 45%; (p < 0,05). Las complicaciones en la etapa 1 fueron 30%, en la 2: 28% y en la 3: 17%, siendo complicaciones Dindo-Clavien III o más, el 6%, 13% y 5%, respectivamente, p NS. Conclusiones: Aa pesar de su complejidad, las hepatectomías videolaparoscópicas son técnicamente reproducibles. Adquiriendo experiencia, podemos aumentar la aplicabilidad, a favor de la patología oncológica y complejidad, sin comprometer la seguridad del paciente.


ABSTRACT Background: Despite laparoscopic liver resection has significantly evolved, most hepatectomies are performed by the conventional approach. Objective: The aim of this study is to present the initial experience and applicability of laparoscopic liver resections. Material and methods: We conducted a retrospective analysis of patients undergoing liver resection between August 2010 and December 2019. Perioperative, intraoperative and postoperative variables were analyzed. To evaluate applicability, the sample was divided into 3 stages: stage 1, from August 2010 to December 2013; stage 2, from January 2014 to December 2016; and stage 3, from January 2017 to December 2019. Results: Of 385 liver resections performed, 119 were laparoscopic procedures: 53 (44%) were pure laparoscopic procedures, 64 (54%) were hand-assisted (64 patients) and 2 corresponded to hybrid procedures. Global applicability was 31%. In stage 1 1: 23%, in 2: 30% and in 3: 44% (p < 0.05). Malignant lesions: stage 1: 36%, stage 2: 67% and stage 3: 72% (p < 0.05). Major liver resections: 13%, 31% and 32% in stages 1, 2, and 3, respectively (p < 0.05). Conversion rate was 12%, 0% and 11%, respectively (p NS). Hepatic pedicle clamping was used in 6%, 5% and 45%; (p < 0.05). Complications in stage 1 were 30%, in stage 2: 28% and in stage 3: 17%, and Clavien-Dindo complications grade 3 or greater were 6%, 13% and 5%, respectively, p NS. Conclusions: Laparoscopic liver resections are complex procedures but technically reproducible. Applicability increases with the acquisition of experience, not only in malignant lesions but also in complex lesions ensuring safety for the patient.
