Lesión hepática asociado a hemoperitoneo masivo secundario a trauma, reporte de caso / Liver injury associated with massive hemoperitoneum secondary to trauma, case report

Resumen Descripción del caso: Paciente de 23 años con hemorragia abdominal de origen no claro, que posteriormente presenta inestabilidad hemodinámica, requiriendo manejo quirúrgico en tres ocasiones con evolución satisfactoria. Hallazgos clínicos: Presentó sangrado cuantificado de 5500 cc en cavidad abdominal (grado IV - clasificación ATLS) con lesiones hepáticas en los segmentos I, IV y VIII, sin hallazgos sugestivos de trauma al examen físico, ni otros hallazgos traumáticos internos. Tratamiento y resultados: Se llevó a cabo una intervención quirúrgica precoz mediante laparotomía exploratoria con hallazgos ya descritos, además de dos tiempos quirúrgicos adicionales que llevaron al control del sangrado, con evolución satisfactoria. Relevancia clínica: El sangrado abdominal y laceración de víscera sólida secundario a trauma cerrado de abdomen es una etiología común en pacientes jóvenes masculinos, siendo contrario a esta afirmación el sangrado de origen hepático sin trauma es una etiología poco común. El presente caso resulta ser una dificultad diagnóstica en cuanto a la etiología, ya que lo evidenciado en la exploración quirúrgica no concuerda con el examen físico externo, sin una historia clínica clara al ingreso se deja la interrogante de la causa.

Summary: Case description: 23-year-old patient with abdominal hemorrhage of unclear origin, who subsequently presented hemodynamic instability, requiring surgical management on three occasions with satisfactory evolution. Clinical findings: she presented quantified bleeding of 5500 cc in the abdominal cavity (grade IV-ATLS classification) with liver lesions in segments I, IV and VIII, without findings suggestive of trauma on physical examination, or other internal traumatic findings. Treatment and results: An early surgical intervention was carried out through exploratory laparotomy with findings already described, in addition to two additional surgical procedures that led to control of bleeding, with satisfactory evolution. Clinical relevance: Abdominal bleeding and solid viscus laceration secondary to blunt abdominal trauma is a common etiology in young male patients, contrary to this statement, bleeding of hepatic origin without trauma is a rare etiology. The present case turns out to be a diagnostic difficulty in terms of etiology, since what was evidenced in the surgical exploration does not agree with the external physical examination, without a clear clinical history at admission, the question of the cause is left.

Introduction: Nonalcoholic fatty liver disease is one of the main causes of liver disease. Cytokeratin 18 emerges as a non-invasive marker for the assessment of liver fibrosis. The objective of the work was to validate the use of cytokeratin 18 in peripheral blood in the diagnosis and evolution of patients with non-alcoholic fatty liver disease. Methodology: To validate cytokeratin 18 in the diagnosis, a case-control study was carried out. The case group was patients over 18 years of age, of both sexes, with a diagnosis of non-alcoholic fatty liver disease linked to metabolic syndrome, recruited between 2/2/2019 to 2/2/2020. The control group were blood donors. They were matched 1-1 for age and sex. Cytokeratin 18 was quantified in peripheral blood of both groups. To validate cytokeratin 18 in the evolution of patients with non-alcoholic fatty liver disease, a prospective, longitudinal study was carried out. The group of patients recruited were followed for one year under standard treatment, at the end of which cytokeratin 18 was quantified in peripheral blood. Continuous variables are expressed with the mean and standard deviation. It was analyzed with Student's t test, α error < 5%. Results: 13 patients make up the case group (12 women), 53 ± 11 years old, with BMI 35.01 ± 8.9 kg/m2. The pre-treatment cytokeratin 18 value was 1410 ± 120 IU, and the post-treatment value was 117 ± 56, p < 0.005. The control group was 13 people (12 women), 43.4 ± 8.1 years and BMI 28.10 ± 5.4 kg/m2 The cytokeratin 18 value was 193 ± 7.2 IU, p < 0.005 vs. pretreatment case group. Conclusions: Cytokeratin 18 is higher in patients with non-alcoholic fatty liver disease, being statistically significant, and decreases with treatment with statistical significance, and may become a useful marker in this group of patients.

Identificación de infección por el virus de la inmunodeficiencia humana en dos receptores de órgano sólido tres años después del trasplante / Identification of HIV infection in two solid organ recipients three years after transplantation

Resumen El examen de rutina de los donantes de órganos para detectar la infección por el virus de la inmunodeficiencia humana (HIV) ha hecho que la transmisión del virus mediante el trasplante de órganos sea poco común. Sin embargo, a pesar de las pruebas de detección de rutina, la transmisión del HIV continúa siendo un riesgo del trasplante de órganos ya que, a diferencia de los tejidos, los órganos sólidos no se pueden procesar, desinfectar, ni modificar para inactivar patógenos infecciosos. A continuación, se describe un caso de posible transmisión de HIV por trasplante de órganos de un donante previamente seronegativo a dos de sus receptores.

Abstract Routine screening of organ donors to detect human immunodeficiency virus (HIV) infection has detected the rare transmission of the virus through organ transplantation. However, despite routine screening, HIV transmission remains a risk in organ transplantation since, unlike tissues, solid organs cannot be processed, disinfected, or modified to inactivate infectious pathogens. A case of possible transmission of HIV by organ transplant is described below, from a previously seronegative donor to two recipients.

Retos y estrategias en el manejo de la trombosis de la vena porta / Challenges and strategies in the management of portal vein thrombosis

La trombosis de la vena porta (TVP) en pacientes con o sin cirrosis hepática (CH) se define como una obstrucción de la vena porta debido a la formación de un trombo que puede extenderse a las venas mesentéricas superiores y esplénica. Esta es una complicación común de la enfermedad hepática avanzada. Se creía que la TVP se producía predominantemente debido al potencial protrombótico del paciente con CH, ya que se observaba una mayor incidencia de TVP en CH con una puntuación MELD y Child-Pugh más altas, con una prevalencia informada del 10 % al 25%.

Portal vein thrombosis (PVT) in patients with or without hepatic cirrhosis (CH) is defined as an obstruction of the portal vein due to the formation of a thrombus that may extend to the superior mesenteric and splenic veins. This is a common complication of advanced liver disease. It was believed that PVT predominantly occurred due to the prothrombotic potential of the patient with CH, as a higher incidence of PVT was observed in CH with higher MELD and Child-Pugh scores, with a reported prevalence of 10% to 25%.

Complicaciones vasculares postrasplante hepático, una situación con alta morbimortalidad / Vascular complications after liver transplantation: A complication with high morbidity and mortality

Introducción. El trasplante hepático es el tratamiento indicado en aquellas enfermedades del hígado en las cuales ya se han agotado otras medidas terapéuticas, y es un procedimiento complejo. Las complicaciones postquirúrgicas se relacionan con alta morbimortalidad y pueden llevar a desenlaces fatales; las complicaciones vasculares son las de mayor mortalidad, por lo que es crucial la detección temprana y el tratamiento oportuno. El objetivo de este estudio fue caracterizar los pacientes que presentaron complicaciones vasculares posterior a trasplante hepático. Métodos. Estudio descriptivo, retrospectivo, con seguimiento a los pacientes sometidos a trasplante hepático en la Fundación Cardiovascular, entre los años 2013 y 2023, que presentaron complicaciones vasculares. Se evaluó el tipo de complicación, los factores de riesgo y los desenlaces postquirúrgicos. Resultados. Se incluyeron en total 82 pacientes trasplantados, con un predominio del sexo masculino 59,8 % (n=49); la principal indicación del trasplante fue el alcoholismo (21,9 %). Veinte pacientes presentaron complicaciones vasculares; la más frecuente fue trombosis de arteria hepática, en el 45 % (n=9). En tres de estos casos se requirió nuevo trasplante. Conclusión. Las complicaciones vasculares empeoran la evolución clínica postoperatoria de los pacientes y están relacionadas con alta morbimortalidad, por lo cual es crucial la valoración multidisciplinaria, el diagnóstico oportuno y la intervención temprana para disminuir los desenlaces fatales.

Introduction. Liver transplant is the treatment indicated for those liver diseases in which other therapeutic measures have already been exhausted, and it is a complex procedure. Post-surgical complications are related to high morbidity and mortality and can lead to fatal outcomes. Vascular complications are the ones with the highest mortality, so early detection and timely treatment are crucial. The objective of this study was to characterize patients who presented vascular complications after liver transplantation. Methods. Descriptive, retrospective study, with follow-up of patients undergoing liver transplant at the Fundación Cardiovascular, between 2013 and 2023, who presented vascular complications. The type of complication, risk factors and postsurgical outcomes were evaluated. Results. A total of 82 transplant patients were included, with a predominance of males with 59.8% (n=49); the main indication for transplant was alcoholism (21.9%). Twenty patients presented vascular complications; the most frequent was hepatic artery thrombosis 45% (n=9). In three of these cases a new transplant was required. Conclusion. Vascular complications worsen the postoperative clinical course of patients and are associated with high morbidity and mortality, which is why multidisciplinary assessment, diagnosis and early intervention are crucial to reduce fatal outcomes.

Clinical and biochemical profile of scrub typhus patients with emphasis on liver dysfunction in a tertiary care centre in South Rajasthan

Background: Scrub typhus is a zoonotic infectious disease presenting commonly with acute febrile illness of variable severity and symptoms. It mimics other more prevalent tropical febrile illnesses such as dengue, malaria, and leptospirosis. Prevalence is high in and around Udaipur due to hilly terrains and agricultural farmlands. Multisystem involvement is common but liver dysfunction is a fatal comorbidity. Methods: In a retrospective observational study, we analyzed the clinical, biochemical, and demographic parameters of 85 patients of scrub typhus. The study population was distributed into four groups for abnormal liver chemistries based on American College of Gastroenterology (ACG) clinical guidelines: normal, borderline high, mild elevation, and moderate elevation. Results: Almost 80% of patients had abnormal liver chemistries including either serum bilirubin or transaminases. More than 30% of patients were categorized in group 2 and group 3 of the abnormal liver chemistries. Group 4 with moderate to severe liver dysfunction had 15.3% (n=13) patients. Thrombocytopenia and elevated blood urea and Creatinine were significantly seen in patients with both scrub typhus and liver dysfunction. Conclusions: Thus, in our study prevalence of hepatitis and jaundice with multiorgan failure in scrub typhus patients was significantly high. Timely identification of systemic complications and screening of liver chemistries on presentation is of utmost importance for better outcomes, among seriously ill patients.

Sarcoma de Ewing/tumor neuroectodérmico primitivo hepático / Ewing sarcoma/primitive hepatic neuroectodermal tumor

Resumen El sarcoma de Ewing (ES) y el tumor neuroectodérmi co primitivo (PNET) pertenecen al grupo de neoplasias denominadas tumores de células pequeñas y redondas. Los PNET se dividen en centrales y periféricos. El ES y los PNET periféricos surgen del tejido óseo, de los tejidos blandos o nervios periféricos. Presentamos un caso de ES/PNET hepático en un hombre sano que inició cuatro meses antes de la consulta con síntomas abdominales y pérdida de peso. La endoscopia digestiva alta y la analí tica no revelaron hallazgos relevantes. En la tomografía de abdomen se evidenció hígado aumentado de tamaño a expensas de lesión sólida que comprometía todos sus segmentos con realce al contraste endovenoso y grandes áreas de necrosis. Comprimía y desplazaba estructuras vecinas. Se realizó biopsia con aguja gruesa de la lesión hepática: neoplasia de células pequeñas y redondas. La inmunohistoquímica reveló negatividad para CD45, CKA1/A3, cromogranina, sinaptofisina y citoqueratinas CK7 y CK20. Expresión tenue de CD56 y positividad de CD99, FLI-1 y NKX2. Realizó tratamiento quimioterápico con carboplatino y etopósido por 6 ciclos con mejoría clínica y tolerancia al mismo. En imágenes de control se evidenció reducción de la masa con afección del lóbulo hepático derecho, compromiso de la vena cava inferior, infiltración de la glándula suprarrenal y polo superior del riñón derechos. Se remitió a cirugía hepatobiliar para resección quirúrgica de la lesión residual. El paciente rechazó el procedimiento quirúrgico. Nuestro objetivo es destacar el desafío diagnóstico clínico e histológico de esta entidad que obliga a descartar otras entidades clínicas.

Abstract Ewing sarcoma (ES) and primitive neuroectodermal tumor (PNET) belong to the group of neoplasms called small round cell tumors. PNETs have been divided into central and peripheral. ES and peripheral PNETs arise from bones, soft tissues, or peripheral nerves. We pres ent a case of hepatic ES/PNET in a healthy man that began four months before consultation with abdominal symptoms and weight loss. Upper gastrointestinal en doscopy and laboratory tests revealed no notable find ings. The abdominal tomography revealed an enlarged liver due to a solid lesion that involved all its segments with intravenous contrast enhancement and large areas of necrosis. It compressed and displaced neighboring structures. Core needle biopsy of the liver lesion was per formed: small round cell neoplasm. Immunohistochemis try revealed negativity for CD45, CKA1/A3, chromogranin, synaptophysin, and cytokeratins CK7 and CK20. Dim CD56 expression and CD99, FLI-1, and NKX2 positivity. He underwent chemotherapy treatment with carboplatin and etoposide for 6 cycles with clinical improvement and tolerance. Control images showed reduction of the mass with involvement of the right hepatic lobe, involvement of the inferior vena cava, infiltration of the right adrenal gland and upper pole of the right kidney. He was referred to hepatobiliary surgery for surgical resection of the residual lesion. The patient rejected the proposed surgi cal procedure. Our objective is to highlight the clinical and histological diagnostic challenge of this entity that requires ruling out other clinical entities.

Trasplante hepático como tratamiento de intoxicación por paracetamol / Liver transplantation as treatment for acetaminophen poisoning

Resumen El paracetamol es una droga analgésica y antipiré tica comúnmente utilizada, que ha experimentado un aumento en su consumo en los últimos años en nuestro medio. También se ha observado un incremento en el número de sobredosis accidentales e intencionales que fueron atendidas por el sistema de salud. Su toxicidad es dosis dependiente y puede causar falla hepática fulminante, convirtiéndose en una de las principales razones de trasplante hepático en países angloparlan tes. Se presenta el caso de una mujer de 28 años con antecedentes de depresión mayor y cinco intentos de suicidio previos, quien ingirió deliberadamente una cantidad significativa de comprimidos de paracetamol. Desarrolló una falla hepática fulminante y acidosis metabólica, por lo que fue sometida a un trasplante hepático de emergencia debido a la gravedad de su condición evolucionando favorablemente. La decisión de realizar un trasplante hepático en casos graves como este y bajo una condición de vulnerabilidad psiquiátrica grave, es un desafío y debe considerarse cuidadosamente. Este caso en particular ilustra la im portancia de la atención multidisciplinaria incluyendo la evaluación psiquiátrica en pacientes con intoxicación por paracetamol.

Abstract Acetaminophen is a commonly used analgesic and antipyretic drug, which has experienced an increase in its consumption in recent years in our environment. There has also been an increase in the number of accidental and intentional overdoses that were treated by the health system. Its toxicity is dose-dependent and can cause ful minant liver failure, becoming one of the main reasons for liver transplantation in English-speaking countries. The case of a 28-year-old woman with a history of major depression and five previous suicide attempts, who de liberately ingested a significant amount of paracetamol tablets, is here presented. She developed fulminant liver failure and metabolic acidosis, for which she underwent an emergency liver transplant due to the severity of her condition, from which she evolved favorably. The decision to perform a liver transplant in serious cases like this and under a condition of severe psychiatric vulnerability is challenging and must be carefully considered. This particular case illustrates the importance of multidisci plinary care including psychiatric evaluation in patients with acetaminophen poisoning.

Tratamiento no operatorio en traumatismo abdominal cerrado. Experiencia en un hospital Interzonal de la provincia de Buenos Aires / Nonoperative management of blunt abdominal trauma. Experience in a regional hospital of the province of Buenos Aires

RESUMEN Antecedentes: En las últimas décadas ha habido un cambio considerable hacia un enfoque más conservador en el tratamiento del traumatismocerrado de abdomen, con énfasis en la preservación de la función de órganos; actualmente, el tratamiento no operatorio (TNO) se ha convertido en la técnica de manejo estándar en pacientes hemodinámicamente estables con lesiones de órgano sólido. Objetivo: Describir las variables clínicas asociadas a la tasa de éxito en una serie de pacientes con TNO de trauma abdominal cerrado con lesión de órganos sólidos. Material y métodos: Estudio retrospectivo, observacional, longitudinal, analítico entre enero de 2017 y diciembre de 2022, sobre pacientes admitidos con diagnóstico de traumatismo abdominal cerrado. Las variables evaluadas fueron: edad, sexo, estadía hospitalaria, complicaciones, requerimiento de transfusiones, tasa de éxito y mortalidad. Resultados: De 2590 pacientes ingresados por Guardia de Cirugía General, 24 pacientes se internaron con diagnóstico de traumatismo cerrado de abdomen. Fueron excluidos 15 pacientes por no cumplir con los criterios de inclusión. Los 9 pacientes seleccionados tuvieron un promedio de edad de 39 años (15-80) y 9 fueron varones. En el 36% presentaron lesiones esplénicas grados I-II, 27% presentó lesión renal grado II y el 18% restante con lesión hepática grado II. La tasa de éxito del tratamiento fue del 100% en nuestra serie sin evidenciar fallos en la terapéutica instaurada. Conclusión: Con los criterios empleados en TNO del traumatismo abdominal cerrado con lesión de órganos sólidos fue factible y permitió alcanzar una alta tasa de éxito, sin mortalidad.

ABSTRACT Background: In recent decades, there has been a significant shift toward a more conservative approach to the management of blunt abdominal trauma with an emphasis on preserving organ function; currently, non-operative management (NOM) has become the standard of care for hemodynamically stable patients with solid organ injury. Objective: The aim of this study was to determine the different clinical variables associated with the success rate of NOM of blunt abdominal trauma with involving solid organs. Material and methods: We conducted a retrospective, observational, longitudinal, and analytical study of patients admitted for blunt abdominal trauma between January 1, 2017, and December 1, 2022. The variables evaluated were age, sex, length of hospital stay, complications, transfusion requirements, success rate and mortality. Results: Between January 2017 and December 2022, of 2590 patients seen in the emergency department, 24 were admitted with a diagnosis of blunt abdominal trauma. Fifteen patients did not meet the inclusion criteria. The mean age of the 9 patients included was 39 years (15-80 years) and 6 were men. Thirty-six percent had grade I and II splenic lesions, 27% had grade II renal lesions, and 18% had grade II hepatic lesions. The success rate of our series was 100% and there were no failures. Conclusion: The variables analyzed allowed us to affirm that NOM of blunt abdominal trauma with solid organ injury was feasible and allowed us to achieve a high success rate, without deaths.

A hospital-based study on acute on chronic liver failure underlying etiology and precipitating factors

Background: Acute-on-chronic liver failure (ACLF) is an increasingly recognised entity that includes the acute deterioration of chronic liver disease usually associated with a precipitating event, development of one or more organ failure and high short-term mortality. Methods: This is a prospective observational study. Clinical data of patients admitted with ACLF at Goa Medical College between November 2019 to November 2021 are summarized and analyzed using relevant statistical tests. Results: A total of 70 patient抯 data was collected. Most common cause of underlying chronic liver disease was alcohol (85.7%) followed by hepatitis B (4.3%), autoimmune diseases (4.3%), cryptogenic (4.3%) and hepatitis C (1.4%). Infections were the most common precipitating factors for ACLF (42.8%) followed by alcohol (28.5%), upper gastrointestinal bleeding (21.42%), drug (AKT) induced (1.42%), unknown cause (10%). Conclusions: Infection and alcohol were found to be important precipitating factors. A multicentre study involving larger numbers of patients are required to know further details and to form a standard treatment protocol.

Prediction of esophageal varices in cirrhosis by using splenic stiffness measurement

Background: Predicting esophageal varices in cirrhosis using the measurement of splenic stiffness is an exciting area of study. Vein enlargement in the lower esophagus, known as varices, is a common symptom of cirrhosis caused by portal hypertension. These varicose veins are potentially fatal since they bleed easily. The present study aims to predict the OV in cirrhosis patients by splenic stiffness in and around this region. Methods: After receiving permission from the Institutional Ethics Committee, the study was performed. The present study authors measured splenic stiffness and liver stiffness by using FibroScan in 112 consecutive cirrhotic patients who met the inclusion criteria. Patients were also assessed by hepatic venous pressure gradient (HVPG), upper gastrointestinal endoscopy, liver stiffness, liver spleen diameter to platelet ratio score, and platelet count to spleen diameter ratio. Results: Among 112 patients enrolled, 64 patients had valid liver stiffness and splenic stiffness measurement, and 64 patients had EV (small, n=23 and large n=42). There was a significant difference in median liver stiffness (54.2 vs. 21.3 kPa, p<0.05), splenic stiffness (56.1 vs. 30 kPa, p<0.05), liver spleen diameter to platelet ratio score (6.3 vs. 2.7, p<0.05), and platelet count to spleen diameter ratio (798 vs 1,241, p<0.05) between patients with OV and those without OV. Conclusions: Non-invasive markers, such as splenic stiffness, may help identify individuals with cirrhosis who are at risk of having esophageal varices, especially large ones, and who are at risk of bleeding, the study's authors conclude.

Experience in the treatment of liver echinococcosis in Grodno Region, Belarus

Background: A parasitic hydatid disease called liver echinococcosis is brought on by the tapeworm echinococcus and is a reason for concern for global health. In addition to the liver, the lungs can harbor parasites. In the life cycle of parasites, humans occupy a middle position. Depending on the size and intensity of the cyst, the clinical signs can vary and be non-specific. The complications include bleeding, perforation, suppuration, cyst rupture, mechanical jaundice, and portal hypertension. Here is an analysis of own results of surgical treatment of patients with liver echinococcosis in Grodno region, Belarus between June 2012 to October 2022. Methods: The research design was cross-sectional. Diagnostic methods that are instrumental and laboratory-based include a general blood test, a biochemical blood test, an enzyme immunoassay (IFA), abdominal and retroperitoneal MRIs and ultrasounds, abdominal and chest CT scans and brain scans. There were 10 men and 17 women among the 27 patients. The age range of the majority of the patients was 18 to 83. Results: All patients underwent resections, including laparoscopic procedures. One of the patients in our series of cases received a two-stage therapy regimen due to a secondary focus of echinococcosis in the left lung. In our series of cases, no postoperative complications or mortality occurred. Conclusions: Patients with hepatic echinococcosis should be treated at specialized hospitals. Abdominal, chest, and brain CT scans are required in order to search for additional foci. When it comes to treating echinococcosis, minimal invasive surgical procedures should be preferred.

Clinico-etiological profile of acute liver failure in children in a tertiary care hospital of northernmost India

Background: Acute liver failure is a life-threatening condition with sudden onset liver injury, decreased liver functions, hepatic encephalopathy, and coagulopathy in patients without preexisting liver disease. The objective of this study was to find out the clinical and etiological factors of acute liver failure in children.Methods: This study was a hospital based prospective observational study conducted from November 2017 to October 2019 at Pediatric Intensive Care Unit (PICU) of Postgraduate Department of Pediatrics, Government Medical College Srinagar, Kashmir. Fifty-one consecutive patients of ALF in the age group of 1 to 18 years were included in this study.Results: The most common clinical presentation in our study was jaundice which was present in all cases followed by anorexia (90.2%), vomiting (84.3%), fever (76.5%) and abdominal pain (64.7%). HE was present at admission in 54.9% cases and exaggerated DTR抯 was present in 49% cases. Of the other clinical manifestations, bleeding was present in 49% cases, ascites in 33.3% cases and edema in 5.9% cases. Infections (76.5%) were the most common cause of ALF in children followed by indeterminate (9.8%), autoimmune (5.9%), drug induced (3.9%), Wilson抯 disease (2%) and HLH (2%). In infectious etiology, the most common cause was Hepatitis A (66.7%) followed by Enteric fever (7.8%) and Hepatitis E (2%).Conclusions: The most common clinical manifestation of ALF in children is Jandice. Hepatitis A is the most common cause of ALF in children.

Baveno VII Criteria for the Exclusion of Esophageal Varices in a Peruvian Population: Cross-Sectional Study / Criterios de Baveno VII para la exclusión de várices esofágicas en una población peruana: estudio transversal

Abstract Introduction: Esophageal varices represent one of the main complications in patients with liver cirrhosis. The main objective was to determine the diagnostic performance of the new Baveno VII criteria to exclude the presence of esophageal varices in compensated advanced chronic liver disease (cACLD), in an independent Peruvian population. Materials and methods: A cross-sectional study, including patients with cACLD, upper digestive endoscopy, and transient hepatic elastography from January 2017 to December 2019. Results: The mean age was 59.4 (12.9) years, while the mean measurement of liver stiffness was 27.21 (14.6) kPa. The prevalence of esophageal varices was 85.6%; non-alcoholic fatty liver disease (NAFLD) (63.6%) was the most prevalent etiology, followed by viral hepatitis (14.4%). For esophageal varices exclusion, Baveno VII criteria for all etiologies demonstrated adequate sensitivity and negative predictive value (sensitivity: 96.7%; 95% confidence interval [CI]: 92.3%-98.8%; negative predictive value: 76.9%, 95% CI: 56.4% -91%). However, better diagnostic performance was found when applying the Baveno VII criteria without considering NAFLD patients (sensitivity: 98.4%, 95% CI: 79.2% -99.2%; negative predictive value: 90.9%, 95% CI: 79.2% -99.2%). This would prevent 14% of endoscopic studies with a 9% risk of failing to detect esophageal varices. Conclusions: The Baveno VII criteria present good diagnostic performance for the exclusion of esophageal varices, especially in patients with cACLD without NAFLD, in an independent Peruvian population.

Resumen Introducción: Las várices esofágicas representan una de las principales complicaciones en pacientes con cirrosis hepática. El objetivo principal fue determinar el rendimiento diagnóstico de los nuevos criterios de Baveno VII para excluir la presencia de várices esofágicas en la enfermedad hepática crónica compensada (cACLD), en una población peruana independiente. Materiales y métodos: Estudio transversal que incluyó a pacientes con cACLD, endoscopia digestiva alta y elastografía hepática transitoria desde enero de 2017 hasta diciembre de 2019. Resultados: La edad media fue de 59,4 (12,9) años, mientras que la medición media de rigidez hepática fue de 27,21 (14,6) kPa. La prevalencia de várices esofágicas fue del 85,6%; la enfermedad metabólica asociada al hígado graso (MASLD) (63,6%) fue la etiología más prevalente, seguida de la hepatitis viral (14,4%). Para la exclusión de várices esofágicas, los criterios de Baveno VII para todas las etiologías demostraron una sensibilidad y un valor predictivo negativo adecuados (sensibilidad: 96,7%; intervalo de confianza [IC] del 95%: 92,3%-98,8%; valor predictivo negativo: 76,9%, IC 95%: 56,4%-91%). Sin embargo, se encontró un mejor rendimiento diagnóstico al aplicar los criterios de Baveno VII sin considerar a los pacientes con MASLD (sensibilidad: 98,4%, IC 95%: 79,2%-99,2%; valor predictivo negativo: 90,9%, IC 95%: 79,2%-99,2%). Se evitaría el 14% de estudios endoscópicos con un riesgo del 9% de no detectar várices esofágicas. Conclusiones: Los criterios de Baveno VII presentan buen rendimiento diagnóstico para la exclusión de várices esofágicas, especialmente en pacientes con cACLD sin MASLD, en una población peruana independiente.

Presentación inusual de coriocarcinoma metastásico a hígado y pulmón: un reporte de caso / Unusual presentation of metastatic choriocarcinoma to liver and lung: a case report

La enfermedad trofoblástica gestacional (ETG) es un trastorno proliferativo del trofoblasto. Incluye la mola hidatidiforme, el coriocarcinoma, la mola invasiva, el tumor trofoblástico del lecho placentario y el tumor trofoblástico epitelioide. Las últimas cuatro hacen parte de la neoplasia trofoblástica gestacional, que agrupa menos del 1% de todos los tumores ginecológicos. La incidencia de la ETG puede variar, siendo aproximadamente de 1 a 3 de cada 1.000 embarazos en América del Norte y Europa. El coriocarcinoma es la forma más agresiva por su rápida invasión vascular y compromiso metastásico. Sin embargo, es un tumor muy quimiosensible con una alta tasa de respuestas y posibilidad de curación superior al 90%. Se presenta el caso de una paciente de 40 años quien ingresó al servicio de urgencias por disnea súbita secundaria a tromboembolia pulmonar y posteriormente tras el inicio de anticoagulación presentó hemoperitoneo debido a lesiones hepáticas metastásicas de un coriocarcinoma, además de compromiso metastásico pulmonar. Se presenta este caso por ser una patología poco frecuente, agresiva y con presentaciones inusuales, con el fin de mostrar la importancia de un diagnóstico y tratamiento oportuno.

Gestational trophoblastic disease (GTD) is a condition in which the trophoblast, a layer of cells surrounding the embryo, develops abnormally. GTD includes both pre-malignant and malignant pathologies, such as hydatidiform mole, choriocarcinoma, invasive mole, placental site trophoblastic tumor, and epithelioid trophoblastic tumor. Although GTD is rare, it affects about 1 to 3 out of every 1,000 pregnancies in North America and Europe. Choriocarcinoma is the most aggressive form of GTD, as it can quickly invade blood vessels and metastasize to other parts of the body. However, it is highly responsive to chemotherapy, with a cure rate of over 90%. In this case, a 40-year-old patient presented to the emergency department with sudden dyspnea due to pulmonary embolism. After starting anticoagulation therapy, she developed hemoperitoneum due to the spread of choriocarcinoma to her liver, as well as pulmonary metastases. This case is noteworthy because of its unusual presentation and aggressive nature, underscoring the importance of early diagnosis and treatment.

Carcinoma sarcomatoide hepático primario metastásico, una neoplasia infrecuente / Primary hepatic sarcomatoid carcinoma, an unusual case

Resumen El carcinoma sarcomatoide primario hepático es un tumor agresivo que representa el 0.4-0.7% de todas las neoplasias primarias hepáticas. Se asocia a hepa topatía por virus hepatotropos, es más prevalente en la población asiática y en su histología se evidencian componentes de carcinoma y sarcoma. No posee carac terísticas clínicas ni imagenológicas patognomónicas y su diagnóstico se realiza en base a los hallazgos de la anatomía patológica e inmunohistoquímica. La cirugía en estadio localizado representa la única modalidad terapéutica con impacto en la sobrevida. Reportamos el caso de una paciente de 72 años, coreana, con an tecedentes de hepatopatía crónica por virus B, a quien se le diagnosticó un carcinoma sarcomatoide hepático primario con metástasis ósea y ganglionares.

Abstract Primary hepatic sarcomatoid carcinoma is a very ag gressive tumor, representing 0.4-0.7% of all primary he patic neoplasms. The disease is associated with liver dis ease due to hepatotropic viruses and is more prevalent in Asians. Histology shows sarcomatous and carcinoma components. It does not have pathognomonic clinical or imaging characteristics and its diagnosis is based on the pathological and immunohistochemistry findings. Surgery could prolong survival in localized stages. We report the case of a 72-year-old Korean patient with a history of chronic liver disease due to B virus, who was diagnosed with primary hepatic sarcomatoid carcinoma with bone and lymph node metastases.

RESUMEN Antecedentes: la cirugía hepática ha evolucionado con el correr del tiempo. No existe bibliografía publicada sobre experiencia previa de hepatectomía en Corrientes. Nuestro grupo de trabajo se desenvuelve en el ámbito público y privado. Objetivo: describir los resultados iniciales de una serie consecutiva de pacientes con hepatectomías de distinta extensión, por el mismo equipo quirúrgico. Material y métodos: trabajo retrospectivo, observacional, descriptivo, sobre datos de las historias clínicas y libros de quirófano de pacientes con hepatectomías realizadas entre septiembre de 2019 y enero de 2023, en la práctica pública y privada. Resultados: fueron intervenidos 27 pacientes, con media de edad 53 años (25-72); 16 eran mujeres. El abordaje fue convencional en 25 casos y laparoscópico en 2. Se realizaron 4 hepatectomías mayores y 23 menores. Los diagnósticos fueron de patología maligna en 22 oportunidades y benigna en 5. La sobrevida a los 90 días fue de 96,2%. La mortalidad fue de 1 paciente (3,7%). Con respecto a las complicaciones, 2 pacientes (7,4%) presentaron abscesos hepáticos en el posoperatorio, 2 pacientes (7,4%) requirieron reintervención quirúrgica por sangrado, con buena evolución posterior y alta hospitalaria. Conclusión: la morbimortalidad en la serie descripta estuvo en relación con lo comunicado por otros autores.

ABSTRACT Background: Liver surgery has evolved over time. There are no prior publications on the experience of liver surgery in the province of Corrientes. Our work group operates in both the public and private sectors. Objective: The aim of this study was to describe the initial results of a consecutive series of patients undergoing different types of liver resections, performed by the same surgical team. Material and methods: We conducted a retrospective, observational, and descriptive study based on data from the medical records and operating room records of patients undergoing liver resection at public and private institutions from September 2019 to January 2023. Results: A total of 27 patients were operated on; mean age was 53 years (25-72) and 16 were women. We used the conventional approach in 25 cases and laparoscopy in 2. Four procedures were major liver resections and 23 were minor liver resections, The diagnoses were cancer in 22 cases and benign conditions in 5. Survival at 90 days was 96.2% One patient died (3.7%). The complications included postoperative liver abscesses in 2 patients (7.4%) and re-operation due to bleeding in 2 patients (7.4%), who had a subsequent favorable course and were discharged from the hospital. Conclusion: The morbidity and mortality in the described series were similar to those reported by other authors.

Resección hepática en enfermedad de Caroli unilobar / Liver resection in monolobar Caroli's disease

RESUMEN La enfermedad de Caroli es un trastorno congénito causado por malformación de la placa ductal. Se manifiesta con litiasis intrahepática y colangitis recurrente, habitualmente en personas jóvenes. Los hallazgos imagenológicos incluyen dilatación multifocal y segmentaria de los conductos biliares intrahepáticos. El colangiocarcinoma puede aparecer como complicación a largo plazo debido a la inflamación crónica de los conductos, por lo que debe estar siempre presente dentro de los posibles diagnósticos diferenciales. Se describe el caso infrecuente de una mujer de 52 años que presentó un cuadro de obstrucción biliar poscolecistectomía laparoscópica y requirió en su tratamiento quirúrgico la resección de los segmentos hepáticos II y III por enfermedad de Caroli, con buena evolución.

ABSTRACT Caroli's disease is a congenital disorder caused by a defect of the ductal plate. The clinical picture includes intrahepatic duct lithiasis and recurrent cholangitis usually in young people. The imaging tests reveal the presence of multifocal and segmental dilatation of the intrahepatic bile ducts. Cholangiocarcinoma can develop as a long-term complication of chronic bile duct inflammation and should always be considered as a differential diagnosis. We describe a rare case of a 52-year-old woman who presented with bile duct obstruction after laparoscopic cholecystectomy and required resection of liver segments II and III due to Caroli's disease with a favorable outcome.

Factores de riesgo asociados a mala adherencia en adolescentes trasplantados hepáticos en transición / Risk factors associated with poor adherence in adolescent liver transplant recipients in transition

Cada vez más pacientes trasplantados hepáticos durante la edad pediátrica alcanzan la adultez debido al aumento en las tasas de sobrevida a largo plazo, por lo que requieren continuar su atención en un centro de adultos. Este pasaje entre centros se asocia con peores resultados clínicos y mayor mala adherencia, debido al momento de vulnerabilidad que representa este momento en la atención médica y por el mismo momento vital atravesado por el paciente adolescente. La mayoría de los centros de trasplantes establecieron programas de transición para mejorar estos resultados. Para que estos programas sean efectivos, deben conocerse las barreras y los facilitadores de adherencia tanto en el paciente como en su entorno. El objetivo de este trabajo es reconocer estos factores de riesgo y su relación con mala adherencia y resultados clínicos, y realizar un seguimiento a corto plazo de los pacientes transferidos a un centro de atención de adultos. Para esto, se realizó una encuesta pre y post derivación a una cohorte de pacientes adolescentes del Hospital Garrahan. Para medir mala adherencia se utilizaron métodos objetivos y subjetivos, cada uno de los cuales correlacionó con distintos factores de riesgo, como presencia de violencia, consumo de sustancias y déficit educativo. Como conclusión, medir la mala adherencia es complejo debido a que su origen es multifactorial. Al parecer, combinar cuestionarios validados con entrevistas no estructuradas es la estrategia más efectiva para detectar mala adherencia en la consulta médica. Luego, las variables psicosociales están cobrando cada vez más relevancia y deben ser consideradas en los programas de transición de los servicios de trasplante si se quiere lograr un seguimiento a largo plazo exitoso (AU)

An increasing number of pediatric liver transplant patients reach adulthood due to the increase in long-term survival rates, and therefore require continued care in an adult center. This transition between centers is associated with worse clinical outcomes and poorer adherence, due to the vulnerability that this moment in medical care represents and the same vital moment that the adolescent patient goes through. Most transplant centers have established Transition Programs to improve these outcomes. For these programs to be effective, the barriers and facilitators of adherence in both the patient and their environment should be known. The aim of this study was to identify these risk factors and their relationship with poor adherence and clinical outcomes, and to perform a short-term follow-up of patients transferred to an adult care center. For this purpose, a pre- and post-referral survey was conducted on a cohort of adolescent patients from the Garrahan Hospital. Objective and subjective methods were used to measure poor adherence, each of which correlated with different risk factors, such as the presence of violence, substance use, and educational deficits. In conclusion, measuring poor adherence is complex because its origin is multifactorial. Combining validated questionnaires with unstructured interviews seems to be the most effective strategy for detecting poor adherence in the medical consultation. Therefore, psychosocial variables are becoming increasingly relevant and should be considered in the Transition Programs of transplantation services if a successful longterm follow-up is to be achieved (AU)
