ABSTRACT
Introdução: As operações laparoscópicas, assistidas por robô e a abertas são técnicas cirúrgicas comumente utilizadas na vida diária. A viabilidade e os resultados em curto e longo prazos dos procedimentos laparoscópicos e robóticos têm sido amplamente relatados. Objetivos: Comparar os dados clínicos e oncológicos da cirurgia assistida por robô e laparoscópica no câncer retal. Métodos: Foram pesquisados o Pubmed/Medline, Embase, e Cochrane Library para artigos relevantes publicados até 2021. Estudos baseados na comparabilidade entre operação assistida por robô e laparoscópica para câncer retal foram designados. Os parâmetros analisados incluíram tempo operatório, conversão para procedimento aberto, perda estimada de sangue, tempo de recuperação da função intestinal, tempo de internação, vazamento da anastomose e complicações pós-operatórias. Resultados: Operação assistida por robô foi associada com maior tempo operatório (342 vs.192 min na cirurgia laparoscópica, p<0,001), menor conversão para procedimento aberto, menor tempo de internação hospitalar e recuperação mais rápida da função intestinal, menores complicações pós-operatórias de forma significativa (p=0,041). A perda estimada de sangue, a taxa de vazamento da anastomose e os resultados oncológicos, incluindo o número de linfonodos extraídos, não mostraram diferenças significativas entre os grupos. Conclusão: A cirurgia assistida por robô para câncer retal mostrou maior tempo operatório, menor conversão, taxas de recuperação da função intestinal mais rápidas e menor permanência no hospital. Seus resultados oncológicos forram semelhantes à cirurgia laparoscópica.
Introduction: Laparoscopic surgery, robot-assisted surgery and open surgery are the most commonly used surgical techniques in daily living. The feasibility and short- and long-term results of laparoscopic and robotic procedures have been widely reported. Objectives: To compare the clinical and oncological results of robot-assisted and laparoscopic surgery for rectal cancer. Methods: PubMed/Medline, Embase, The Cochrane Library were searched for relevant articles published until 2021. Studies based on comparability between robot-assisted and laparoscopic surgery for rectal cancer were designed. The parameters analyzed included operative time, conversion to open surgery, estimated blood loss, bowel function recovery time, length of hospital stay, anastomosis leak, and postoperative complications. Results: The robot-assisted surgery group was associated with longer operative time (342 vs. 192 min in laparoscopic surgery,p <0.001), lower conversion to open surgery, shorter length of hospital stay, faster bowel function recovery and lower postoperative complications significantly (p=0.041). Estimated blood loss, anastomosis leak rate, and oncological outcomes including the number of lymph nodes extracted showed no significant differences between groups. Conclusion: Robot-assisted surgery for rectal cancer showed longer operative time, lower conversion, faster bowel function recovery rates, shorter hospital stay, and similar oncological outcomes compared to laparoscopic surgery.

Resumen Introducción: la enfermedad de Wilson es una enfermedad heterogénea causada por mutaciones en el gen ATP7B. La presentación clínica es variable, en fenotipos hepáticos y neuropsiquiátricos. El objetivo de este estudio es describir una cohorte retrospectiva de pacientes. Materiales y métodos: estudio retrospectivo descriptivo de pacientes atendidos en el Hospital Pablo Tobón Uribe desde enero de 2004 a septiembre de 2017. Resultados: se reportaron 27 pacientes, 17 hombres y 10 mujeres. El tiempo de seguimiento medio fue de 2,18 años, el 40% presentó síntomas neurológicos; el 29%, psiquiátricos; y el 85%, alteración hepática. En el laboratorio, el 85% presentó ceruloplasmina baja; 55%, cobre urinario alto; en casos con biopsia hepática, 7 tenían depósito de cobre en coloraciones especiales. En neuroimágenes, el 84% presentó hallazgos sugestivos de enfermedad de Wilson y en 3 casos se documentó una mutación genética patogénica. Durante el seguimiento, el 51% mejoró clínica o bioquímicamente, el 11% se mantuvo estable y el 18% se deterioró. El 88% de los casos sobrevivió al final del seguimiento. Conclusiones: este estudio es la cohorte retrospectiva más grande de Colombia. Los resultados son base para nuevos estudios poblacionales buscando de manera activa la enfermedad para documentarla en su fase preclínica y, de este modo, impactar en el pronóstico.
Abstract Introduction: Wilson's disease is a heterogeneous disorder caused by mutations in the ATP7B gene. Its clinical presentation is variable in hepatic and neuropsychiatric phenotypes. The aim of this study is to describe a retrospective cohort of patients. Materials and methods: A descriptive retrospective study was carried out in patients treated at the Hospital Pablo Tobón Uribe from January 2004 to September 2017. Results: 27 patients were reported, 17 men and 10 women. The mean follow-up time was 2.18 years. 40% of the patients had neurological symptoms, 29% psychiatric symptoms, and 85% hepatic impairment. Lab tests showed that 85% had low ceruloplasmin and 55% had increased urinary copper. In cases that underwent liver biopsy, 7 had special copper colorations. Neuroimaging revealed that 84% had findings suggestive of Wilson's disease and a pathogenic genetic mutation was documented in 3 cases. During follow-up, 51% improved clinically or biochemically, 11% remained stable, and 18% deteriorated. 88% of cases survived at the end of follow-up. Conclusions: This study is the largest retrospective cohort carried out in Colombia. The results are the basis for new population-based studies actively seeking this disease to describe its preclinical development and thus impact prognosis.

La presente propuesta de diseño busca la interoperabilidad de datos en salud por medio de la integración de un sistema de comunicación a equipos especializados, utilizando las TI (Tecnologías de la Información) y el IoT (Internet de las Cosas) en los equipos biomédicos especializados o monitor que está siendo utilizado actualmente en los centros hospitalarios público a nivel nacional para la medición de signos vitales, con el objetivo de poder brindar una atención sanitaria a pacientes con padecimientos médicos y que necesitan de una constante supervisión y vigilancia. En los centros hospitalarios se cuenta con equipo biomédico especializado que carece de dichas funcionalidades. Esto repercute u obliga al responsable especialista a tener que estar frente al monitor y paciente para poder observar las mediciones o lecturas que presenta un paciente.
This design proposal seeks the interoperability of health data through the integration of a communication system to specialized equipment, using IT (Information Technology) and IoT (Internet of Things) in specialized biomedical equipment or monitor that is currently being used in public hospitals nationwide for the measurement of vital signs, in order to provide health care to patients with medical conditions and who need constant surveillance. Hospitals have specialized biomedical equipment that lacks these functionalities. This forces the responsible specialist to have to be in front of the monitor and the patient to be able to observe the measurements or readings that a patient presents.

ABSTRACT Objective: to evaluate the effectiveness and safety of laparoscopic cholecystectomies performed by residents of the first and second-year of a general surgery residency program. We studied the primary total cost of treatment and complication rates as primary outcomes, comparing the groups operated by senior and resident surgeons. Methods: this was a retrospective cohort study of patients who underwent laparoscopic cholecystectomy performed in a training hospital of large surgical volume in Brazil, in the period between June 1, 2018 and May 31, 2019. The study population comprised patients who underwent elective cholecystectomy due to uncomplicated chronic calculous cholecystitis or to the presence of gallbladder polyps with surgical indication. We divided the cases into three groups, based on the graduation of the main surgeon at the time of the procedure: first-year residents (R1), second-year residents (R2), and trained general surgeons (GS). Results: during the study period, 1,052 laparoscopic cholecystectomies were performed, of which 1,035 procedures met the inclusion criteria, with 78 (7.5%) patients operated on with the participation of first-year residents (R1), 500 (48.3%) patients with the participation of second-year residents (R2), and 457 (44.2%) with the participation of senior surgeons only. There was no difference in conversion rates, complications, and reporting of adverse events between groups. We observed a significant difference regarding hospitalization costs (p = 0.003), with a higher mean for the patients operated with the participation of R1, of US$ 2,671.13, versus US$ 2,414.60 and US$ 2,396.24 for the procedures performed by senior surgeons and R2, respectively. Conclusions: laparoscopic cholecystectomy with the participation of residents is safe, even in their first years of training. There is an additional cost of about 10% in the treatment of patient operated with the participation of first-year residents. There was no significant difference in the cost of the group operated by second-year residents.
RESUMO Objetivo: avaliar a efetividade e segurança da realização de colecistectomias laparoscópicas por residentes do primeiro e segundo ano do programa de cirurgia geral. Foram estudados como desfechos primários o custo médio total de tratamento e os índices de complicações, comparando os grupos operados por cirurgiões seniores e residentes. Métodos: trata-se de estudo de coorte retrospectivo de pacientes submetidos a colecistectomias laparoscópicas realizadas em hospital escola de grande volume cirúrgico, no Brasil, no período entre 01 de junho de 2018 e 31 de maio de 2019. A população do estudo compreendeu pacientes que realizaram colecistectomias eletivas por colecistite calculosa crônica não complicada ou por presença de pólipos de vesícula biliar com indicação cirúrgica. Os casos foram divididos em 3 grupos, baseados na graduação do cirurgião principal no momento do procedimento: residentes do primeiro ano (R1), residentes do segundo ano (R2) e cirurgiões formados (CG). Resultados: no período do estudo, foram realizadas 1.052 colecistectomias videolaparoscópicas, sendo que, após aplicados os critérios de exclusão, foram incluídos no estudo 1.035 procedimentos, com 78 (7,5%) pacientes operados com a participação de residentes do primeiro ano (R1), 500 (48,3%) pacientes com a participação de residentes do segundo ano (R2) e 457 (44,2%) apenas com a participação somente de cirurgiões seniores. Não houve diferença nas taxas de conversão, de complicações e de notificações de eventos adversos entre os grupos. Foi evidenciada diferença com relação aos custos de internação (p= 0,003), sendo observado maior custo médio de internação para os pacientes operados com participação dos R1, com custo médio de US$ 2.671,13, versus US$ 2.414,60 e US$ 2.396,24 das operações realizadas pelos cirurgiões seniores e R2, respectivamente. Conclusões: é segura a realização de colecistectomia videolaparoscópica com a participação de residentes, mesmo em seus primeiros anos de formação. Existe custo adicional de cerca de 10% no tratamento de pacientes operados com a participação de residentes do primeiro ano. Não foi observada diferença significativa no custo do grupo operado por residentes do segundo ano.

Resumen El síndrome de Budd-Chiari (Budd-Chiari syndrome, BCS) es una entidad rara, definida por la obstrucción del flujo venoso del hígado y corresponde a una condición heterogénea tanto en presentación como en manejo terapéutico. A continuación, presentamos un estudio retrospectivo de pacientes con diagnóstico de BCS, atendidos por el grupo de hepatología del el Hospital Pablo Tobón Uribe. Los resultados se expresan como proporciones en las variables categóricas y como medias y rangos para las variables continuas. La edad promedio de presentación fue de 37,7 años y no hubo preponderancia por el género. Los principales síntomas fueron dolor abdominal (91,4 %), ascitis (71,4 %) y hepatomegalia (60 %). Asimismo, 11 pacientes (31,4 %) presentaron hipercoagulabilidad primaria, mientras que en 7 (20 %) se encontró algún síndrome mieloproliferativo. Además, 6 (17,1 %) tenían neoplasias extrahepáticas: 3 con compresión mecánica y 3 por hipercoagulabilidad asociada; solo en 1 caso se documentaron membranas en la vena cava inferior. Y en 5 casos no fue posible determinar la causa de trombosis. De igual forma, 32 pacientes (91,4 %) recibieron anticoagulación como primer manejo; solo 4 sujetos fueron remitidos a procedimientos: 2 a angioplastia, 1 a derivación portosistémica intrahepática transyugular (Transjugular Intrahepatic Portosystemic Shunt, TIPS) y 1 a trasplante ortotópico hepático (TOH). Luego de ello, 17 (48,5 %) recibieron procedimientos invasivos como segunda línea: 8 (22,8 %) se condujeron a angioplastia y endoprótesis (stent), 5 (14,29 %) a TIPS y 4 necesitaron TOH. Así, los 6 pacientes que se llevaron a TIPS no necesitaron trasplante hepático. El BCS continúa siendo una condición poco frecuente que afecta la salud de personas jóvenes, tanto hombres como mujeres, con una presentación clínica heterogénea. Sin embargo, en la mayoría de los casos ocurre por una causa desencadenante clara, entre las cuales predominan las trombofilias y los síndromes mieloproliferativos. El uso de medidas terapéuticas invasivas, especialmente de la selección temprana de los enfermos que se benefician de TIPS, ha cambiado la historia natural y el pronóstico de este grupo de pacientes.
Abstract Budd-Chiari syndrome (BCS) is a rare disorder characterized by the obstruction of the veins of the liver. Both its presentation and therapeutic management are heterogenous. The following is a retrospective study of patients diagnosed with BCS treated by the hepatology service at the Hospital Pablo Tobón Uribe. The results of the categorical variables are expressed as proportions and the continuous variables as means and ranges. The average age of onset of this disease was 37.7 years and it was not predominant in neither sex. The most common symptoms were abdominal pain (91.4%), ascites (71.4%) and hepatomegaly (60%). Out of 35 patients, 11 (31.4%) had primary hypercoagulability, 7 (20%) had some myeloproliferative disorder, 6 (17.1%) had extrahepatic malignancies -3 with mechanical compression and 3 due to associated hypercoagulability-, and 1 case had a membranous obstruction of the inferior vena cava. 32 patients (91.4%) received anticoagulation as first-line therapy and only 4 were taken to surgery: 2 to angioplasty, 1 to transjugular intrahepatic portosystemic shunt (TIPS) and 1 to orthotopic liver transplantation (OLT). On the other hand, 17 (48.5%) individuals underwent invasive procedures as a second-line therapy, of which 8 (22.8%) underwent angioplasty and stenting, 5 (14.29%) underwent TIPS and 4 needed OLT. The 6 patients who were taken to TIPS did not need liver transplants. Budd-Chiari syndrome remains a rare condition affecting the health of young men and women alike, with a heterogeneous clinical presentation but, in most cases, with a clear trigger where thrombophilic and myeloproliferative disorders predominate. The use of invasive therapeutic measures, especially the early selection of patients who may benefit from TIPS, has changed the natural course and prognosis of this group of patients.

Resumen Objetivo: el trasplante hepático es el tratamiento de elección para la falla hepática aguda y crónica. Los resultados en el trasplante hepático han mejorado en los últimos años, así que el objetivo de nuestro trabajo es comparar la experiencia de un centro en Colombia en dos períodos de tiempo diferentes. Pacientes y métodos: estudio descriptivo retrospectivo donde se analizaron pacientes adultos con primer trasplante hepático en dos períodos; serie 1, entre 2004-2010 (241 pacientes); y serie 2, entre 2011-2016 (142 pacientes). Resultados: la edad promedio fue de 54 años, el 57 % eran hombres y con un puntaje Model for End-stage Liver Disease (MELD) promedio de 20, sin cambios significativos en las características del donante y del receptor en los dos períodos. Las principales indicaciones de trasplante hepático fueron cirrosis por alcohol, cirrosis criptogénica y cirrosis por hepatitis autoinmune, con una disminución de los casos de hepatitis B y C en la serie 2. El 30 % de los pacientes tenía hepatocarcinoma. La supervivencia de los pacientes a 1 año fue de 81 % frente a 91 % y a 5 años fue de 71 % frente a 80 %, respectivamente. Las principales causas de muerte fueron: cáncer, enfermedad cardiovascular y sepsis. Existió un incremento significativo en las complicaciones biliares, sin diferencias en las complicaciones infecciosas, vasculares y el rechazo celular entre los dos períodos. Conclusión: el trasplante hepático en este centro en Colombia se relaciona con excelentes resultados a corto y mediano plazo, con una mejoría significativa en la supervivencia de los pacientes en los últimos años y con resultados similares a los reportados en otros centros del mundo.
Abstract Objective: Liver transplantation is the treatment of choice for acute and chronic liver failure. Liver transplantation results have improved in recent years, so the objective of our work was to compare results from two different periods of time at a center in Colombia. Patients and Methods: This is a retrospective descriptive study comparing first time adult liver transplant patients from 2004-2010 (Series 1: 241 patients) and from 2011-2016 (Series 2: 142 patients). Results: The average patient age was 54 years, 57% were men, and the average MELD score was 20. There were no significant differences between the characteristics of donors and recipients from one period to the next. The main indications for liver transplantation were alcoholic cirrhosis and cryptogenic and autoimmune hepatitis. Series 2 contained fewer hepatitis B and C cases than did Series 1. Thirty percent of the patients had hepatocellular carcinoma. The one-year survival rates were 81% in Series 1 and 91% in Series 2, whereas five-year survival rates were 71% and 80%, respectively. The main causes of death were cancer, cardiovascular disease and sepsis. From the first period to the second period, there was a significant increase in biliary complications but no differences in infectious complications, vascular complications or cellular rejection. Conclusion: Short and medium term liver transplantation results at this center in Colombia have been excellent, but there have been significant improvements in patient survival rates in recent years that are similar to those reported elsewhere in the world.

There are few published real-world studies on hepatitis C in Latin America. This paper describes a cohort of Colombian subjects treated with direct-acting antiviral agents. A total of 195 patients from 5 hepatology centers in 4 Colombian cities were retrospectively studied. For each patient, serum biomarkers were obtained, and Child-Pugh, MELD, cirrhosis and fibrosis stage were calculated. Additionally, viral load was quantified at initiation, end of treatment and at 12 weeks of completion. Adverse effects were recorded. Patients with liver transplant were compared with non-transplanted patients in terms of serum biomarkers. The patients had received 9 different regimes. The most prevalent viral genotype was 1b (81.5%). Overall, 186 patients (95.4%) attained sustained virologic response. When comparing transplanted vs. non-transplanted patients, those in the non-transplanted group were more likely to have cirrhosis (52.6% vs. 12.5%, p = 0.0004). Pre-treatment viral load was higher in the transplant group (1 743 575 IQR = 1 038 062-4 252 719 vs. 345 769 IQR = 125 806-842 239; p < 0.0001) as well as ALT and AST levels (82.5 IQR 43.5-115.5 vs. 37.0 IQR = 24.7-73.3; p = 0.0009 and 70 IQR = 41-140 vs. 37 IQR = 24-68; p = 0.004 respectively). Adverse events were reported by 28.7% of the patients; asthenia (5.6%) was the most prevalent. Our results are comparable with those from other countries in terms of therapy and biomarkers. However, our cohort reported less adverse events. Further research is needed in the region.
Existen pocas publicaciones de evidencias del mundo real sobre hepatitis C en América Latina. En este estudio presentamos una cohorte colombiana de pacientes tratados con agentes antivirales de acción directa. Fueron analizados retrospectivamente 195 pacientes seleccionados en 5 centros de hepatología en 4 ciudades de Colombia. Dos tercios fueron mujeres y la mitad tenía ≥ 62 años. De cada uno se cuantificaron biomarcadores séricos, escala de Child-Pugh, MELD y grado de cirrosis y fibrosis. Se cuantificó carga viral al inicio, al final y a las 12 semanas después de completado el tratamiento. Se comparó la frecuencia de efectos adversos de medicamentos en trasplantados vs. no trasplantados. Los pacientes recibieron 9 esquemas de tratamiento diferentes. El genotipo más prevalente fue 1b (81.5%). La respuesta viral sostenida fue alcanzada por 186 pacientes (95.4%). El grupo no trasplantado tenía mayor frecuencia de cirrosis (52.6% vs. 12.5%, p = 0.0004). En los trasplantados, la carga viral pre-tratamiento era mayor (1 743 575 IQR = 1 038 062-4 252 719 vs. 345 769 IQR = 125 806-842 239; p = < 0.0001) igual que la ALT y la AST (82.5 IQR 43.5-115.5 vs. 37.0 IQR = 24.7-73.3; p = 0.0009 and 70 IQR = 41-140 vs. 37 IQR = 24-68; p = 0.004 respectivamente). El 28.7% refirió efectos adversos, siendo el más prevalente la astenia (5.6%). Nuestros resultados fueron comparables a los de estudios publicados en términos de terapia y biomarcadores pero nuestra cohorte presentó menos efectos adversos. Se requiere más investigación en la región.

ABSTRACT Objective: To determine whether pre-hospital statin use is associated with lower renal replacement therapy requirement and/or death during intensive care unit stay. Methods: Prospective cohort analysis. We analyzed 670 patients consecutively admitted to the intensive care unit of an academic tertiary-care hospital. Patients with ages ranging from 18 to 80 years admitted to the intensive care unit within the last 48 hours were included in the study. Results: Mean age was 66±16.1 years old, mean body mass index 26.6±4/9kg/m2 and mean abdominal circumference was of 97±22cm. The statin group comprised 18.2% of patients and had lower renal replacement therapy requirement and/or mortality (OR: 0.41; 95%CI: 0.18-0.93; p=0.03). The statin group also had lower risk of developing sepsis during intensive care unit stay (OR: 0.42; 95%CI: 0.22-0.77; p=0.006) and had a reduction in hospital length-of-stay (14.7±17.5 days versus 22.3±48 days; p=0.006). Statin therapy was associated with a protective role in critical care setting independently of confounding variables, such as gender, age, C-reactive protein, need of mechanical ventilation, use of pressor agents and presence of diabetes and/or coronary disease. Conclusion: Statin therapy prior to hospital admission was associated with lower mortality, lower renal replacement therapy requirement and sepsis rates.
RESUMO Objetivo: Determinar se o uso pré-admissão hospitalar de estatina está associado com menor necessidade de diálise e/ou óbito durante internação em unidade de terapia intensiva. Métodos: Análise de coorte prospectiva. Foram incluídos consecutivamente 670 pacientes admitidos na unidade de terapia intensiva de um hospital acadêmico de cuidados terciários. Os pacientes incluídos deveriam ter entre 18 e 80 anos e ter sido admitidos na unidade de terapia intensiva nas últimas 48 horas. Resultados: A média da idade dos pacientes foi de 66±16,1 anos. O índice de massa corporal foi de 26,6±4/9kg/m2 e a circunferência abdominal média foi de 97±22cm. O grupo que fez uso de estatina pré-admissão hospitalar (18,2% dos pacientes) necessitou menos de terapia de substituição renal e/ou evoluiu para óbito (OR: 0,41; IC95%: 0,18-0,93; p=0,03). O grupo que fez uso de estatina também apresentou menor risco de evoluir com sepse durante a internação na unidade de terapia intensiva (OR: 0,42; IC95%: 0,22-0,77; p=0,006) e teve menor duração da hospitalização (14,7±17,5 dias versus 22,3±48 dias; p=0,006). A terapia pré-admissão hospitalar com estatina foi associada a papel protetor no cenário da terapia intensiva independentemente de variáveis confundidoras, como sexo, idade, proteína C-reativa, necessidade de ventilação mecânica, uso de vasopressores e diagnóstico de diabetes e/ou coronariopatia. Conclusão: A terapia com estatina antes da admissão hospitalar foi associada a menor mortalidade, menor necessidade de terapia de substituição renal e taxa de ocorrência de sepse.

ABSTRACT Objective To investigate the impacts of continuous venovenous hemodiafiltration on the microcirculation in patients with acute kidney injury. Methods A prospective observational pilot study conducted in a 40-bed, open clinical-surgical intensive care unit of a private tertiary care hospital located in the city of São Paulo (SP), Brazil. Microcirculation was assessed using near-infrared spectroscopy by means of a 15mm probe placed over the thenar eminence. Vascular occlusion test was performed on the forearm to be submitted to near-infrared spectroscopy by inflation of a sphygmomanometer cuff to 30mmHg higher than the systolic arterial pressure. The primary endpoint was the assessment of near-infrared spectroscopy-derived parameters immediately before, 1, 4 and 24 hours after the initiation of continuous venovenous hemodiafiltration. Results Nine patients were included in this pilot study over a period of 2 months. Minimum tissue oxygen saturation measured during the vascular occlusion test was the only near-infrared spectroscopy-derived parameter to differed over the time (decrease compared to baseline values up to 24 hours after initiation of continuous venovenous hemodiafiltration). Conclusion The impacts of microcirculatory dysfunction on clinical outcomes of patients undergoing to continuous venovenous hemodiafiltration need to be further investigated.
RESUMO Objetivo Avaliar o impacto da hemodiafiltração venovenosa contínua na microcirculação de pacientes com lesão renal aguda. Métodos Estudo piloto, prospectivo e observacional conduzido em uma unidade de terapia intensiva clínico-cirúrgica aberta, com 40 leitos, localizada em um hospital terciário, privado, na cidade de São Paulo (SP), Brasil. A microcirculação foi avaliada empregando-se a espectroscopia no infravermelho próximo, por meio de uma sonda de 15mm posicionada sobre a eminência tenar. O teste de oclusão vascular foi realizado no antebraço a ser submetido à espectroscopia no infravermelho próximo, inflando-se o manguito de um esfigmomanômetro a um valor 30mmHg acima da pressão arterial sistólica. O desfecho primário foi a avaliação dos parâmetros derivados por espectroscopia no infravermelho próximo imediatamente antes, 1, 4 e 24 horas após o início da hemodiafiltração venovenosa contínua. Resultados Foram incluídos nove pacientes neste estudo piloto ao longo de 2 meses. A saturação de oxigênio tecidual mínima mensurada durante o teste de oclusão vascular foi o único parâmetro derivado por espectroscopia no infravermelho próximo que diferiu ao longo do tempo, com queda em relação aos valores iniciais nas primeiras 24 horas após o início da hemodiafiltração venovenosa contínua. Conclusão A influência da disfunção microcirculatória sobre os desfechos clínicos de pacientes submetidos à hemodiafiltração venovenosa contínua precisa ser melhor investigada.

Resumen Introducción y objetivos: el análisis de la impedancia basal nocturna media (IBNM) se ha propuesto para incrementar la precisión diagnóstica de enfermedad por reflujo erosiva (ERGE). Nuestro objetivo fue evaluar el rendimiento diagnóstico de esta prueba en un grupo de pacientes con ERGE conocida. Materiales y métodos: incluimos 123 individuos (58 con ERGE y 65 controles sanos) a quienes se les realizó pH-impedanciometría (pH-IMM) consecutiva entre enero de 2015 y junio de 2017. Todos los pacientes tenían endoscopia tomada en los 6 meses previos. El tiempo de exposición ácida (TEA) anormal (>4,2%) y la presencia de pirosis y/o regurgitación en los 6 meses previos fueron los criterios para el diagnóstico de ERGE. Se encontraron 58 pacientes con ERGE, 24 con enfermedad por reflujo erosiva (ERE) y 34 con enfermedad por reflujo no erosiva (ERNE). Los 65 restantes fueron controles sanos (CS) asintomáticos con EGD y pH-IMM normales. Todos los trazos de pH-IMM se reanalizaron para medir la IBNM por un segundo observador que desconocía los datos previos. El análisis estadístico incluyó pruebas múltiples de Bonferroni para comparar los grupos; regresión lineal para variables continuas; y análisis de curva ROC para buscar valor IBNM con mayor rendimiento. Para los diferentes parámetros de precisión diagnóstica se utilizó el punto de corte de la IBNM. Se usó significancia estadística con valor de p <0,01 e intervalos de confianza de 95% (IC 95%) para todos los cálculos. Resultados: los pacientes con ERE y ERNE presentaron valores de IBNM significativamente más bajos que el grupo control (p <0,01). Se observó una correlación negativa entre los valores de la IBNM y TEA (r = 0,59; p = <0,001), y también entre la IBNM y número de eventos de reflujo (r = 0,37; p = <0,001). En el análisis de curva ROC, el área bajo la curva de la IBNM fue de 0,941 (IC 95%: 0,894-0,987) y el punto de corte con mayor eficiencia 1102 ohms (sensibilidad 98,5%; especificidad 84,5%). Usando este valor (<1,102), la IBNM tuvo una sensibilidad para detectar ERGE de 91% (ERNE 86% y ERE 100%) y una especificidad de 98%. Conclusión: la IBNM tiene alta sensibilidad y especificidad para el diagnóstico de la ERGE. Adicionar esta prueba al análisis convencional de la pH-impedancia y a los métodos actuales de estudio de la ERGE puede mejorar significativamente nuestra capacidad para diagnosticar la enfermedad.
Abstract Introduction and Objectives: Analysis of nocturnal basal impedance (IBNM) has been proposed as a way to increase accuracy of GERD diagnosis. Our objective was to evaluate the diagnostic performance of this test in a group of patients known to have GERD. Materials and methods: We included 123 individuals: 58 with GERD and 65 healthy controls. They underwent consecutive pH-impedance monitoring between January 2015 and June 2017. All had undergone endoscopy in the 6 months prior to testing. Criteria used for diagnosis of GERD were abnormal acid exposure time (AET > 4.2%), pyrosis and/or regurgitation in the previous 6 months. We found 58 patients with GERD of whom 24 had erosive reflux disease (ERE) and 34 had non-erosive reflux disease (NERD). The remaining 65 were asymptomatic healthy controls with normal endoscopic results and pH impedance monitoring. A second observer who did not know the previous data measurements analyzed all pH impedance monitoring traces for IBMN. Statistical analysis included multiple Bonferroni tests for comparison between groups, linear regression for continuous variables, and receiver operating characteristic (ROC) curve analysis to find high performance IBNM values. The IBNM cutoff point was used for diagnostic precision parameters. Statistical significance was set at p <0.01, and 95% confidence intervals were used for all calculations. Results: IBNM measures were significantly lower for patients with ERE and NERD than for the control group (p <0.01). A negative correlation was observed between IBNM and acid exposure time values (r = 0.59, p = <0.001) and also between IBNM and number of reflux events (r = 0.37, p = <0.001). ROC curve analysis found that the area under the curve for IBNM was 0.941 (95% CI: 0.894-0.987), and the cutoff point with the highest efficiency was 1,102 ohms (sensitivity 98.5%, specificity 84.5%). Using this value (<1.102), the IBNM had a sensitivity for detecting GERD of 91% (NERD 86% and ERE 100%) and a specificity of 98%. Conclusion: IBNM has high sensitivity and specificity for diagnosis of GERD. Addition of this test to conventional pH-impedance analysis and current methods for studying GERD can significantly improve our ability to diagnose this disease.

Introducción El uso de aloinjerto óseo irradiado en las revisiones de cadera es controvertido por las alteraciones que genera este tratamiento en el hueso. Se realizó una evaluación de una serie consecutiva de pacientes con revisión en que se utilizó este tipo de tejido. Materiales y métodos Se realizó una evaluación retrospectiva de una serie de casos consecutivos (2005-2013) de 54 pacientes (55 caderas) intervenidos por un solo cirujano. Resultados Dos pacientes requirieron una nueva revisión y tres pacientes terminaron sin prótesis por infección profunda. Se realizó el seguimiento de 39 caderas, en el cual se destaca una mejoría de la puntuación de Merle d'Aubigné-Postel, con un promedio de 9 a 14; se encontró que 11 de los 27 acetábulos (40,7%) presentaron una migración en algún plano mayor o igual a 5 mm y todos los restantes, menos uno, tuvieron alguna migración. La media de hundimiento del tallo femoral fue 4,9 mm. La incorporación del injerto se constató en el 14,8% (4/27) en el acetábulo y el 50% (8/16) en el fémur. Discusión Esta serie muestra excelentes resultados clínicos en general, pero, mientras el injerto irradiado en forma de chapas para el fémur y estructural para el acetábulo tiene buen resultado clínico y radiológico, y un buen índice de incorporación, el tejido que llega en chips para técnica de injerto compactado provoca fallas radiológicas muy frecuentes (con relación a lo publicado) y, a pesar de los buenos resultados clínicos y de la seguridad biológica ofrecida, debe indicarse con precaución y nunca debe ser la primera opción. Nivel de evidencia clínica Nivel IV.
Background The use of irradiated bone allograft in hip revision is controversial because of the alterations caused by this treatment in the allograft bone. A report is presented on a consecutive series of patients undergoing revision hip replacement using this type of tissue. Materials and methods A retrospective evaluation was performed on a series of consecutive cases (2005-2013) of 54 patients (55 hips) operated on by a single surgeon. Results Two patients required a new revision and three patients completed without prosthesis due to deep infection. Follow-up of 39 hips was performed, with an improvement in the Merle d'Aubigné-Postel score from 9 to 14. It was found that 11 (40.7%) of the 27 sockets had a migration in some plane greater or equal to 5 mm, and in the remainder all had some migration minus one. The mean subsidence of the femoral stem was 4.9 mm. The incorporation of the graft was in the acetabulum in 14.8% (4/27), and 50% (8/16) in the femur. Discussion This series shows excellent clinical results in general, but the irradiated graft in the form of plates for the femur, and structural for the acetabulum has good clinical and radiological results, and good incorporation index. Although the impaction bone grafting had good clinical outcomes and a biological safety, it should be indicated with caution and should never be the first option. Evidence level IV.

Resumen Introducción: La infección crónica por el virus de la hepatitis C es un problema de salud pública y se estima que hay más de 180 millones de personas infectadas en el mundo. En Colombia no se conoce la epidemiología de la infección ni los genotipos virales más frecuentes. Objetivo. Describir los genotipos y subtipos del virus de la hepatitis C en pacientes colombianos infectados. Materiales y métodos: Se hizo un estudio descriptivo y retrospectivo de pruebas realizadas en dos laboratorios de referencia nacional, entre el 2003 y el 2015, mediante electroforesis en geles de poliacrilamida (Polyacrylamide Gel Electrophoresis, PAGE) o reacción en cadena de la polimerasa en tiempo real (quantitative PCR, qPCR). Resultados. Se estudiaron 1.538 aislamientos del virus de la hepatitis C de 1.527 pacientes con una edad promedio de 53 años, de los cuales 70 % tenía entre 40 y 70 años y 52 % eran mujeres. El 57 % de las pruebas se ordenaron en la ciudad de Bogotá, y el 80 % de los casos provenía de los departamentos de Cundinamarca, Valle y Atlántico. Se encontró el genotipo 1 en 88,6 % de los casos, distribuido así: subtipo 1b, 70 %, subtipo 1a, 13,5 %, y no determinado, 5,1 % de los casos; el genotipo 2 se encontró en el 5,4 % de los casos, el 3, en el 2 %, y el 4, en el 4 %. Se encontraron genotipos mixtos en 0,8 % de la muestra. Conclusión: El genotipo 1 del virus de la hepatitis C es el que circula con mayor frecuencia en el país, con predominio del subtipo 1b.
Abstract Introduction: Chronic hepatitis C virus infection is a worldwide public health problem; it has been estimated that over 180 million people are infected with this virus worldwide. Its precise incidence and prevalence (i.e., epidemiology) and the most frequent circulating genotypes in Colombia are unknown. Objective: To describe the hepatitis C virus (HCV) genotypes and subtypes in infected Colombian patients. Materials and methods: We recovered the data on 1,538 HCV isolates from 1,527 patients in two Colombian reference laboratories typed by PAGE or qPCR. Results: Patients' mean age was 53 years; 70% of them were 40 to 70 years old, and 52%, females; 57% of all tests were ordered in Bogotá and 80% of cases were from Cundinamarca, Valle and Atlántico departments. Genotype 1 was detected in 88.6% of cases, distributed as follows: 70% subtype 1b, 13.5% subtype 1a and 5.1%, undetermined subtypes. Genotype 2 was found in 5.4% of the patients, genotype 3 in 2% and genotype 4 in 4%. Mixed genotypes were found in 0.8% of the samples. Conclusion: Genotype 1 is the most common HCV genotype circulating in Colombia, and subtype 1b the most frequent.

Introducción: la hepatitis B es una causa importante de trasplante hepático; produce 1 millón de muertes anuales. El uso de inmunoglobulina antihepatitis B en dosis altas y análogos de nucleósidos redujeron en un 90% la reinfección del injerto. Objetivo: evaluar la eficacia de dosis bajas de inmunoglobulina postrasplante para prevenir la reinfección del injerto. Metodología: serie de casos retrospectiva de pacientes trasplantados en el Hospital Pablo Tobón Uribe, entre enero de 2004 y septiembre de 2014, que recibieron inmunoglobulina después del trasplante. Se evaluaron la carga viral de hepatitis B, las transaminasas y los marcadores serológicos para documentar recaída, además de variables como mortalidad, complicaciones, disfunción del injerto, reacciones adversas y costos. Resultados: fueron 18 pacientes trasplantados con hepatitis B; 50% tenía hepatocarcinoma; 22%, cirrosis; y 22%, insuficiencia hepática aguda. La mediana de seguimiento fue de 43,27 meses (14,7-65,2). De los pacientes, 2 tuvieron antígeno de superficie positivo en el postrasplante y en 1 hubo recaída con carga viral positiva a los 41 meses. La tasa de reinfección del injerto fue del 5,5%. No hubo muertes. Se estimó que el costo de usar dosis bajas de inmunoglobulina fue menor comparado con las dosis altas a 6 meses de terapia; sin embargo, no se hizo estudio de costo-efectividad. La disfunción del injerto fue del 10% a 33 meses. Conclusión: con dosis bajas de inmunoglobulina se previno la reinfección del injerto, similar a lo reportado en otras series. Mientras los esquemas libres de inmunoglobulina logran demostrar su utilidad a largo plazo, usar dosis bajas de inmunoglobulina sigue siendo útil.
Introduction: Hepatitis B results in one million deaths every year and is is an important reason for liver transplantation. The use of anti-hepatitis B immunoglobulin at high doses and nucleoside analogues have reduced reinfection of the graft by 90%. Objective: This study evaluated the efficacy of low doses of immunoglobulin to prevent reinfection of grafts after transplantation. Methodology: This is a retrospective study of a series of patients who had been transplanted and who received immunoglobulin after transplantation at the Hospital Pablo Tobón Uribe between January 2004 and September 2014. Hepatitis B viral load, transaminase and serological markers were used to document relapses. Other variables studied included mortality, complications, graft dysfunction, adverse reactions and costs. Results: There were 18 patients with hepatitis B who had transplants: 50% had hepatocarcinoma, 22% had cirrhosis, and 22% had acute liver failure. The median follow-up time was 43.27 months with a range of 14.7 to 65.2 months. Two patients tested positive for surface antigen in the post-transplant period and one relapsed and had a positive viral load at 41 months. The graft reinfection rate was 5.5%. There were no deaths. It was estimated that the cost of using low doses of immunoglobulin was lower than that of using high doses at 6 months of therapy, but no cost-effectiveness study was done. Graft dysfunction was 10% to 33 months. Conclusion: Low doses of immunoglobulin prevented reinfection of grafts in a way that is similar to that reported in other series. While immunoglobulin free schemes have proven to be useful for the long term, low doses of immunoglobulin remain useful.

Resumen El tratamiento antirretroviral y el manejo adecuados convirtieron a la infección por VIH en una enfermedad crónica con buena sobrevida a largo plazo. Actualmente, más de la mitad de las muertes en estos pacientes se debe a causas no relacionadas con el VIH, y la enfermedad hepática terminal de diversas etiologías es la segunda causa de muerte en estos pacientes, por lo que el trasplante de hígado se ha convertido en una opción de tratamiento para pacientes seleccionados que tengan buen control de la infección por VIH, con una sobrevida postrasplante similar a otras indicaciones. En este reporte, presentamos el caso del primer paciente en Colombia trasplantado de hígado con infección por VIH, con coinfección por virus B, cirrosis hepática y hepatocarcinoma en el Hospital Pablo Tobón Uribe en el año 2010.
Abstract Appropriate antiretroviral treatment and management has transformed HIV into a chronic disease with good long-term survival rates. Currently more than half of the deaths of these patients are due to non-HIV-related causes among which terminal liver disease resulting from various etiologies is the second most frequent cause of death. Consequently, liver transplantation has become a treatment option for selected patients whose HIV infections have been controlled. Post-transplant survival rates are similar to those of other liver transplant patients. This report presents the first liver transplant in Colombia of an HIV infected patient. This patient had a coinfection with Hepatitis B virus as well as cirrhosis of the liver and hepatocellular carcinoma. The procedure was performed in the Hospital Pablo Tobón Uribe in 2010.

La hepatitis crónica, la cirrosis hepática y el carcinoma hepatocelular son las manifestaciones clásicas de la infección crónica por hepatitis B, pero hasta el 20% de los pacientes se presentan con manifestaciones extrahepáticas de la infección. Las principales afecciones extrahepáticas son la poliarteritis nodosa y la enfermedad glomerular; sin embargo, los pacientes pueden consultar con manifestaciones cutáneas, reumatológicas, hematológicas y neurológicas. En este artículo presentamos el caso de una mujer con hepatitis B crónica, quien debutó con una exacerbación/flare acompañada de vasculitis leucocitoclástica y artritis. Los clínicos debemos estar atentos a la presentación extrahepática de la hepatitis B, ya que esta puede asociarse con complicaciones severas y además requerir tratamiento antiviral independiente de la indicación de tratamiento por su enfermedad hepática.
Chronic hepatitis, liver cirrhosis and hepatocellular carcinoma are the classic manifestations of chronic hepatitis B infections, but up to 20% of patients present extrahepatic manifestations of the infection. The most common extrahepatic presentations are polyarteritis nodosa and glomerular disease, but patients can also develop cutaneous, rheumatological, hematological and neurological manifestations. In this article we present the case of a woman with chronic hepatitis B whose initial manifestation was a flare-up accompanied by leukocytoclastic vasculitis and arthritis. Clinicians should be aware of extrahepatic presentations of hepatitis B because they can be associated with severe complications and may also require separate antiviral treatment independent of that indicated for liver disease

El hemangioendotelioma epitelioide hepático es un tumor raro, de naturaleza agresiva y comportamiento impredecible, con una incidencia de menos de 1 caso por millón de personas al año. Se presenta especialmente en mujeres jóvenes y con síntomas no específicos como dolor abdominal y pérdida de peso. La presentación radiológica es con múltiples nódulos o masas periféricas y bilaterales, con retracción de la cápsula, en algunos casos con calcificaciones y compromiso vascular. Debe realizarse biopsia hepática para confirmar el diagnóstico y para descartar diagnósticos alternativos como angiosarcoma, hepatocarcinoma, colangiocarcinoma y metástasis. El manejo depende de la extensión al momento de presentación, aunque solo el 10% de los casos es susceptible de resección. En las últimas décadas, el trasplante hepático se ha convertido en una opción de manejo, con series de casos aisladas reportadas por centros de trasplante en el mundo. En este artículo se presenta la experiencia de 2 pacientes con diagnóstico de hemangioendotelioma epitelioide hepático sin posibilidad de resección, confirmado histológicamente, sin compromiso extrahepático y que fueron llevados a trasplante de hígado exitoso y sin recurrencia de la enfermedad a 4 y 6 años después del trasplante.
Hepatic epithelioid hemangioendothelioma is a rare, aggressive and unpredictable tumor. Its incidence is less than one case per million people per year. Most commonly, it occurs in young women who exhibit nonspecific symptoms such as abdominal pain and weight loss. Radiologically it presents as multiple bilateral and peripheral nodules or masses with retraction of the capsule of the liver. In some cases there is calcification and vascular compromise. A liver biopsy should be performed to confirm the diagnosis and to rule out alternative diagnoses such as angiosarcoma, hepatocellular carcinoma, cholangiocarcinoma and metastasis. Management depends on the extension at presentation, but only 10% of cases are amenable to resection. Although in recent decades liver transplantation has become a management option, only studies of isolated cases reported by various transplant centers around the world have been published so far. In this article, we report our experience with two patients who were diagnosed with hepatic epithelioid hemangioendothelioma in which there were no possibilities of resection. Diagnoses were histologically confirmed, and since the patients had no extra-hepatic compromises, liver transplantations were performed. Both were successful and without recurrence at 4 and 6 years after transplantation.
