Liver abscess due to Granulicatella adiacens in an immunocompetent patient: Case report / Absceso hepático por Granulicatella adiacens

Pyogenic liver abscesses due to Granulicatella adiacens are infections associated with high mortality, mainly in immunocompromised patients. The main microorganisms associated with liver abscesses are Klebsiella pneumoniae, and Escherichia coli, though it may also be polymicrobial. However, case reports describing liver infection by Granulicatella adiacens are scarce. We present the case of an immunocompetent adult patient who presented 15 days of evolution consisting of quantified fever peaks associated with asthenia, adynamia, chills, jaundice and coluria. The initial clinical examination revealed a generalized icteric tint without abdominal pain, and blood pressure with a tendency to hypotension. Biliopancreatic confluent neoplasia, secondary cholangitis and sepsis of biliary origin were suspected, initiating fluid resuscitation and antibiotic therapy; blood cultures and complementary diagnostic studies were taken. Hepatobiliary ultrasound with evidence of an abscess of 73 x 62 mm in segment IV; the bile duct and pancreas were within normal limits. To better characterize the lesion evidenced in the liver, a contrast-enhanced computed tomography of the abdomen was performed. The patient completed antibiotic management with ciprofloxacin, vancomycin, and metronidazole in good condition and was successfully discharged. This is the first pyogenic liver abscess reported caused by Granulicatella adiacens in an immunocompetent patient, in whom early microbiological diagnosis in conjunction with targeted antibiotic treatment and percutaneous drainage of the lesion was decisive in the clinical outcome.

Los abscesos hepáticos piógenos por Granulicatella adiacens son infecciones asociadas a una alta mortalidad, principalmente en pacientes inmunocomprometidos. Los principales microorganismos asociados a los abscesos hepáticos son Klebsiella pneumoniae y Escherichia coli, aunque pueden ser polimicrobianos. Sin embargo, los informes de casos que describen la infección hepática por G. adiacens son muy escasos. Se presenta el caso de un paciente adulto inmunocompetente que presentó 15 días de evolución de picos febriles cuantificados asociados a astenia, adinamia, escalofríos, ictericia y coluria. El examen clínico inicial reveló un tinte ictérico generalizado sin dolor abdominal, y presión arterial con tendencia a la hipotensión. Se sospechó neoplasia biliopancreática confluente, colangitis secundaria y sepsis de origen biliar, y se inició reanimación con líquidos y antibioterapia. Se tomaron hemocultivos y estudios diagnósticos complementarios. En el ultrasonido hepatobiliar, se observó un absceso de 73 x 62 mm en el segmento IV; la vía biliar y el páncreas se encontraron dentro de los límites normales. Se realizaron múltiples pruebas moleculares de detección de microorganismos (FilmArray), y se identificó a G. adiacens como el principal agente patógeno. El paciente completó el manejo antibiótico con ciprofloxacina, vancomicina y metronidazol en buenas condiciones y fue dado de alta con éxito. Este es el primer absceso hepático piógeno reportado causado por G. adiacens en un paciente inmunocompetente, en quien el diagnóstico microbiológico temprano en conjunto con el tratamiento antibiótico dirigido y el drenaje percutáneo de la lesión fueron determinantes en el resultado clínico.

Abscesos hepaticos en tiempos de pandemia (covid19) / Hepatic abscesses in time of pandemic (COVID 19)

Introducción. Los abscesos hepáticos son infecciones focales supurativas. La Klebsiella pneumoniae es el agente etiológico más frecuente. Afecta principalmente a hombres de edad media, diabéticos, con afecciones hepáticas o en contexto de inmunodepresión. Se clasifican en abscesos colangíticos, pioflebíticos, hematógenos, por continuidad, traumáticos y criptogénicos, según mecanismo de producción. Se manifiestan con dolor abdominal en hipocondrio derecho, sd. febril y sd. colestásico en presencia de obstrucción de vía biliar. La ecografía, TAC y la Resonancia magnética de abdomen son los métodos de elección para determinar topografía y morfología de las colecciones. El tratamiento consiste en el drenaje oportuno de la colección por vía percutánea o quirúrgica, asociado al tratamiento antibiótico. Objetivos: 1. Análisis epidemiológico de abscesos hepáticos durante la Pandemia por Covid 19 en una Institución privada de Tucumán. 2. Estudiar la fisiopatología y agentes patógenos responsables de los mismos. 3. Comparar estadísticas con era similar no Covid 19. Material y métodos. Estudio descriptivo retrospectivo. Se incluyeron seis pacientes con diagnóstico de Absceso Hepático, cinco de ellos del período de la era Covid 19 y uno de la era no Covid 19. Las variables analizadas fueron: cantidad de pacientes ingresados al Servicio, pacientes con absceso hepático, sexo, edad, comorbilidades, métodos de diagnóstico imagenológico utilizados, localización anatómica del absceso, número de lesiones, microbiología de la muestra quirúrgica y en sangre, tratamiento implementado, días desde el diagnóstico hasta la resolución, STROC y recidiva. Resultados: En el análisis epidemiológico se evidenció un notable descenso de la actividad quirúrgica en el periodo del 2020, respecto al mismo período del año previo, a predominio del mes de abril con un porcentaje de descenso del 52%, coincidiendo este período con el inicio de la cuarentena en la provincia. En nuestra serie resultaron todos masculinos, hipertensos y 3 de ellos diabéticos. Todos estudiados por ecografía y 3 complementaron con TAC con contraste EV. Fueron tratados en un promedio de 48hs desde el diagnóstico. Cultivos positivos, Klebsiella Pn (3), St aureus (1), E. Coli (1), Bacilo gram ­ (1). Hemocultivos: 3 negativos, 2 positivos para Klebsiella Pn y 1 para St. Aureus. 3 pacientes fueron sometidos a drenaje percutáneo, 2 a laparoscópico y uno convencional. Se registraron 2 STROC IIIA y 1 IIIB. Un paciente obitó, el resto recibió alta sanatorial. Se registraron 2 recidivas. Conclusiones: Nuestros pacientes, en su totalidad masculinos y diabéticos, desarrollaron abscesos hepáticos piógenos; el agente patógeno más frecuente fue la Klebsiella Pneumoniae. Los abscesos criptogénicos fueron los más prevalentes. En las recidivas documentadas, se determinó misma ubicación topográfica y agente etiológico del primer episodio, lo que nos lleva a preguntarnos sobre la eficacia del tratamiento implementado en cada caso.

Introduction: liver abscess is a common infection. Klebsiella pneumoniae was de most frecuently etiologic agent. The patients were middle-aged men with diabetes, another liver afection or immunodepression context. According to the production mechanism, they are classified in colangitics, pyophlebics, haematogenes, by continuity, traumatic and cryptogrnics. Patients usually present with right upper quadrant, fever, colestasic síndrome when bile-way obstruction exist. Imaging techniques such as ultrasonography, computed tomography scanning and magnetic resonance are useful tools to demostrtate a space occupying lesión and morfology of liver abscess. Treatment consist in timely drainage by percutaneous or surgical route, plus antibiotic treatment. Objetives: 1. Epidemiological análisis of liver abscesses during the pandemic Covid 19 in a private center in Tucumán. 2. Study physiology and pathogenic agents. 3. Campare statistics whit previusly period. Materials and methods: retrospective descriptive study. Six live abscess diagnosis patient were included, five of them included in stage Covid 19 and only one belong stage no Covid 19. Variables analysed: number of patients belong to the Service, number of patients whit liver abscess diagnosis, sex, age, comorbilities, imaging methods, location and number of abscess, microbiology of surgical sample and blood, treatment, days from diagnosis to resolution, STROC and recidivation. Results: epidemiological análisis showed a decrease in surgeries in the period 2020, compared to the same period of the previous year, a predominance in April with a percentage decrease of 52%, coinciding with the start of quarantine in the province. All patients were male, hypertensive and 3 of them with diabetes. Al lof them studied by ultrasound and tomography with contrast. They were treated at 48hours of diagnosis. Microbiology of surgical sample positive: Klebsiella Pn (3), St aureus (1), E. Coli (1), Bacillos gram ­ (1). Microbiology of blood: 3 negative, 2 positive to Klebsiella Pn and 1 to St. Aureus. 3 patients were drainage by percutaneous , 2 by laparoscopic and 1 by surgical conventional. They registered 2 STROC IIIA y 1 IIIB. 1 patiente dead, the rest were external from hospital. Conclusions: our patients developed liver abscess, they were male, diabetics and the most frecuently agent was the Klebsiella pneumoniae. Criptogenics abscess were the most prevalent. The same topographic location in the liver and the etiologic agent was determined in recurrence. That´s why we wonder about the effectiveness of the treatment implemented.

Morphological characteristics of liver abscesses according its etiology / Características morfológicas de los abscesos hepáticos según su etiología

Although infrequent in the diagnostics areas, liver abscesses are of significant relevance, which is related to the high morbidity and mortality figures they can cause if they are not detected and treated in time. Although multiple operational classifications are described, the one most recognized for its usefulness is that related to its causative agent (pyogenic or bacterial infection, hydatid origin or secondary to infected hydatidosis, and amoebic or by invasive amebiasis). The objective of this article was to generate a study report regarding the morphological characteristics of liver abscesses, characterizing them according to their etiology, as well as describing their study and the latest recommended treatments.

Los abscesos hepáticos son entidades nosológicas de baja frecuencia, pero de significativa relevancia, la que se relacionada con las elevadas cifras de morbilidad y mortalidad que pueden causar si no son detectados y tratados a tiempo. Si bien se describen múltiples clasificaciones operacionales, aquella más reconocida por su utilidad es la relacionada a su agente causal (piógenos o bacterianos, hidatídicos o secundarios a hidatidosis infectada, y amebianos o por amebiasis invasora). El objetivo de este artículo fue generar un documento de estudio respecto de las características morfológicas de los abscesos hepáticos, caracterizándolos de acuerdo con su etiología, así como describir su estudio y tratamiento recomendado de acuerdo con el estado del arte.

Absceso hepático neonatal asociado a cateterización de vasos umbilicales / Neonatal liver abscess associated with an umbilical catheter

INTRODUCCIÓN. Los abscesos hepáticos piógenos en neonatos son una entidad rara con menos de cien casos reportados en la literatura mundial. El diagnóstico en esta edad es difícil porque tanto signos y síntomas son inespecíficos y se relacionan con sepsis. OBJETIVOS. Identificar la clínica y características patológicas del absceso hepático en neonatos y correlacionar al posicionamiento de catéter umbilical en hígado como factor de riesgo asociado para desarrollar absceso hepático en neonatos. MATERIALES Y MÉTODOS. Estudio retrospectivo, descriptivo, informes de casos, con una muestra y población conocida, de 5 pacientes recién nacidos. Criterios de Inclusión: neonatos de ambos sexos con edad gestacional mayor a las 34 semanas de gestación, con antecedentes de mal posicionamiento de catéteres umbilicales documentado mediante un examen de imagen "radiografía". Criterios de Exclusión: pacientes sin el antecedente de cateterización umbilical y/o que no se haya documentado mediante estudio de imagen con la evidencia del catéter colocado de manera errónea en tejido hepático. Se utilizó la base de datos registrada en los archivos del Servicio de Gastroenterología Pediátrica de las interconsultas solicitadas del Servicio de Neonatología y Unidad de Cuidados Intensivos Neonatales del, Hospital Civil de Guadalajara "Dr. Juan I. Menchaca". Jalisco- México, en un tiempo de 5 años, desde Enero 2013 a 2018. RESULTADOS. Fueron cinco pre términos (n=5) entre 34 y 36 semanas, con edad gestacional media de 35 semanas y 2039 gr de peso al nacer. El promedio de días para el diagnóstico fue de 7,8. Cuatro pacientes tuvieron hepatomegalia 80,0% (4;5), el volumen de los abscesos fueron entre 2 y 12mm en lóbulo hepático derecho. CONCLUSIÓN. El absceso hepático es poco común pero su clínica debe sospecharse en un recién nacido con sepsis y antecedente de cateterismo umbilical. El manejo y evolución clínico favorable en el 100,0 % (5;5), de los neonatos y no se requirió resolución quirúrgica.

INTRODUCTION. Pyogenic liver abscesses in neonates are a rare entity with less than one hundred cases reported in the world literature. Diagnosis at this age is difficult because both signs and symptoms are nonspecific and are related to sepsis. OBJECTIVES. Identify the clinical and pathological characteristics of liver abscess in neonates and correlate to the positioning of umbilical catheters in the liver as an associated risk factor for developing liver abscess in neonates. MATERIALS AND METHODS. Retrospective, descriptive study, case reports, with a sample and known population, of 5 newborn patients. Inclusion Criteria: neonates of both sexes with gestational age over 34 weeks of gestation, with a history of poor positioning of umbilical catheters documented by an "x-ray" imaging exam. Exclusion Criteria: patients without a history of umbilical catheterization and / or who have not been documented by imaging study with evidence of the catheter incorrectly placed in liver tissue. The database registered in the archives of the Pediatric Gastroenterology Service of the requested interconsultations of the Neonatal and Neonatal Intensive Care Unit of the Civil Hospital of Guadalajara "Dr. Juan I. Menchaca ". Jalisco- Mexico, in a time of 5 years, from January 2013 to 2018. RESULTS. There were five pre terms (n = 5) between 34 and 36 weeks, with an average gestational age of 35 weeks and 2039 grams of birth weight. The average number of days for diagnosis was 7,8. Four patients had 80,0% hepatomegaly (4; 5), the volume of abscesses was between 2 and 12mm in the right hepatic lobe. CONCLUSION. Hepatic abscess is uncommon but its clinic should be suspected in a newborn with sepsis and a history of umbilical catheterization. Management and favorable clinical evolution in 100,0% (5; 5) of infants and no surgical resolution was required.

Concomitant Liver and Brain Abscesses Caused by Parvimonas Micra / 대한소화기학회지

Anaerobic infections have been reported to be responsible for 3–10% of pyogenic liver abscesses in Korea, and reported anaerobes include Fusobacterium, Bacillus fragilis, and Bacteroides melaninogenicus. Parvimonas micra is an anaerobic, Gram-positive, non-spore-forming bacterial species and a constituent of normal flora on skin, vagina, gastrointestinal tract, and oral cavity that can cause opportunistic infections. However, it has only rarely been reported to be a cause of liver abscess; only one such case has been reported in Korea. We experienced a case of concomitant liver and brain abscesses caused by Parvimonas micra in a non-immunodeficient 65-year-old female patient without diabetes or periodontal disease. Parvimonas micra infection was confirmed by blood culture using VITEK® 2 cards and by bacterial 16s ribosomal RNA gene sequencing. We conclude that we should not overlook anaerobes as a cause of liver abscess.

Pyogenic Liver Abscess Caused by Endoscopic Submucosal Dissection for Early Colon Cancer

Endoscopic submucosal dissection (ESD) is widely used for the treatment of colorectal neoplasia in patients who are candidates for endoscopic resection. In particular, pyogenic liver abscess (PLA), although rare, can occur. To our knowledge, there are no reports of PLA cases after ESD. Therefore, we report a rare case of PLA caused by ESD. A 76-year-old man was referred from a local clinic and admitted to our hospital for colonic ESD for a large polypoid mass. During colonoscopy, a 5-cm mass was seen in the cecum. ESD was performed. Four days after the procedure, he complained of myalgia and abdominal discomfort. Computed tomography revealed a 5.4-cm PLA in the medial segments of the liver. He was treated with antibiotics, and a percutaneous drainage catheter was inserted. Here, we report a very rare complication (PLA) after ESD. In conclusion, comprehensive awareness of the development of PLA is needed in ESD cases.

Laparoscopic Treatment of Hepatic Abscess Caused by an Ingested Foreign Body

Pyogenic hepatic abscess caused by an ingested foreign body is extremely uncommon, and reports on the laparoscopic treatment for it are very rare. We report here on a case of hepatic abscess caused by an ingested chicken bone which was treated with a laparoscopic approach. A 61-year-old man visited an emergency room with the chief complaints of high fever. He was diagnosed with pyogenic liver abscess that contained a sharp calcified foreign body seen on a CT-scan. At first, percutaneous transhepatic drainage of the abscess was performed to achieve recovery of the patient's condition. Subsequent laparoscopic exploration found and removed the foreign body in the lesser sac. The foreign body turned out to be an ingested chicken bone. The patient was discharged on the 10th day after surgery.

Two cases of pyogenic liver abscess due to Klebsiella pneumoniae in immunocompetent children

Pyogenic liver abscess (PLA) can be caused by bacteria entering the liver via the portal vein or primary bacteremia, or it can be cryptogenic. Recently, Klebsiella pneumoniae has been increasingly found as a PLA pathogen. PLA due to this bacterium often leads to formation of extrahepatic abscesses. The treatment of choice is dual therapy with insertion of percutaneous catheter drainage and antibiotic therapy. We report 2 cases of PLA due to K. pneumoniae in immunocompetent children. We successfully treated patient 1 with percutaneous catheter drainage for 18 days and 6-week course of antibiotic therapy. Patient 2 was treated with percutaneous needle aspiration and antibiotic therapy for the same period. In both patients, the PLAs showed the ultrasound-confirmed resolutions after the dual therapy.

Ruptured Gas-forming Pyogenic Liver Abscess into the Peritoneal Cavity Treated Successfully with Medical Treatment / 대한소화기학회지

Gas-forming pyogenic liver abscess (GFPLA) is very rare and has a very high mortality in case of rupture into the abdominal cavity, which usually require surgical treatment. We experienced a case of a ruptured GFPLA due to Klebsiella pneumoniae complicated with peritonitis and sepsis in a 68-year-old diabetic woman. Immediate and aggressive medical treatments including intravenous antibiotics, percutaneous drainage, and continuous renal replacement therapy dramatically improved the liver abscess, peritonitis, and metabolic problems. We report an unusual case of a ruptured GFPLA without surgical management, treated successfully with only medical treatment.

Hepatectomy for pyogenic liver abscess treatment: exception approach? / Hepatectomia para o tratamento do abscesso hepático piogênico: abordagem de exceção?

ABSTRACT Background: Percutaneous drainage for pyogenic liver abscess has been considered the gold-standard approach for the treatment on almost of the cases. However, when percutaneous drainage fails or even in some especial situations, as multiloculate abscess, lobe or segment surgical resection can solve infectious clinical condition. Aim: To report a series of patients who underwent hepatectomy for pyogenic liver abscess performed by a single surgical team. Methods: Eleven patients were operated with ages ranging from 45-73 years (mean and median 66 years). There were eight men and three women. The etiologies were: idiopathic (n=4), biliary (n=2), radiofrequency (n=2), direct extension (n=1), portal (n=1), and arterial (n=1). The mean lesion diameter was 9.27 cm (6-20 cm). Results: The mean operation length was 180 min (120-300). The mean intra-operative blood loss was 448 ml (50-1500). Surgical approaches were: right hepatectomy (n=4), left hepatectomy (n=3), left lateral sectioniectomy (n=1), right posterior sectioniectomy (n=2), resection of S8 (n=1), and S1 (n=1). Postoperative morbidity rate was 30%, while mortality was null. Median hospital stay was 18 days (5-45). The median follow-up period was 49 months (13-78). There was single lesion recurrence. Conclusion: Hepatectomy can be done as exception approach for pyogenic hepatic abscess treatment; it is a good therapeutic option in special situations.

RESUMO Racional: A drenagem percutânea do abscesso hepático piogênico tem sido considerada padrão-ouro para o tratamento na maioria dos casos. Mais raramente, quando essa abordagem falha ou em casos de abscessos multiloculados, a ressecção daquele segmento ou lobo destruído pode resolver o contexto infeccioso. Objetivo: Relatar uma série de doentes com abscesso hepático que foram submetidos a hepatectomia. Método: Onze doentes foram operados. A idade variou de 45-73 anos (média e mediana 66). Foram oito homens e três mulheres. As causas foram: idiopática (n=4), biliar (n=2), radiofrequência (n=2), portal (n=1), arterial (n=1), e extensão direta (n=1). A média do tamanho das lesões foi 9,27 cm (6-20). Resultados A média de tempo cirúrgico foi de 180 min (120-300). A média de sangramento intra-operatório foi de 448 ml (50-1500 ml). Os procedimentos cirúrgicos foram: hepatectomia D (n=4), hepatectomia E (n=3), setorectomia lateral E (n=1), setorectomia posterior D (n=2), ressecção do S8 (n=1) e S1 (n=1). A morbidade pós-operatória foi 30%, enquanto a mortalidade foi nula. Mediana de internação foi de 18 dias (5-45). A mediana de seguimento foi 49 meses (13-78). Houve uma única recidiva de lesão. Conclusão: Embora a hepatectomia possa ser considerada conduta de exceção para tratamento do abscesso hepático piogênico, ela deve ser boa opção terapêutica em situações especiais.

Keeping an Eye Out for Klebsiella Endopthalmitis: Klebsiella Pneumoniae Invasive Liver Abscess Syndrome

@#Hypervirulent Klebsiella pneumoniae strain is a major cause of liver abscess and this bacteria has metastatic properties. This distinct liver abscess syndrome has been increasingly reported in Asia over the past two decades, but is emerging as a global disease. We described an 81-year-old lady, who presented to the emergency department with 1-week prior duration of fever and right eye swelling. She had been admitted for recurrent liver abscess prior to this. Hence, she was initially treated as sepsis secondary to recurrent liver abscess. Meanwhile, she was managed concurrently by ophthalmology team for endophtalmitis. Despite the initiation of treatment with antibiotics, she did not show any improvement and required right eye evisceration to treat the sepsis. Invasive liver abscess syndrome with metastatic endophthalmitis should be screened in patient with Klebsiella liver abscess. They should be monitored for ocular symptoms as early recognition can prohibit delays in treatment, which has debilitating consequences.

Puerperal sepsis caused by liver abscess: case report / Sepse puerperal secundária a abscesso hepático: relato de caso

Abstract Introduction: sepsis is a serious public health problem, affecting millions of people in the world each year, with a high mortality rate (one out of four patients) and an increasing incidence. Sepsis is one of the main causes of maternal mortality and an important cause of admission to obstetric intensive care units. Case description: In this study, the authors report the case of a woman having been submitted to cesarean section three days before presenting clinical signs of sepsis and septic shock caused by a liver abscess. The patient had a set of complications secondary to shock, such as thrombocytopenia, coagulopathy, toe ischemia and acute kidney failure. The patient had cholelithiasis and recurrent pain in the right hypochondrium during pregnancy. During hospitalization, the mechanism involved in the development of hepatic abscess was infection of the biliary tract. The patient was treated in an obstetric intensive care unit with antibiotics and drainage of the liver abscess. Progress was favorable and the patient was discharged in good health. Discussion: pyogenic liver abscess during pregnancy and puerperium is a serious condition which represents a diagnostic and therapeutic challenge, with few cases reported. The normally nonspecific clinical and laboratory findings can lead to a late diagnosis, which increases the risk of maternal morbidity and mortality.

Resumo Introdução: a sepse é um problema grave de saúde pública, afetando milhões de pessoas no mundo a cada ano. Apresenta uma alta mortalidade, um em quatro doentes, e vem aumentando sua incidência. É uma das principais causas de mortalidade materna, sendo uma causa importante de admissões emunidades de terapia intensiva obstétrica. Descrição do caso: puérpera, no terceiro dia pós-cesariana, apresentou quadro clinico de sepse e choque séptico secundário a um abscesso hepático piogênico.Evoluiu com complicações secundárias ao choque: plaquetopenia, coagulopatia, isquemia de pododáctilos e insuficiência renal aguda. A paciente era portadora de colelitíase e apresentou repetidas crises álgicas em hipocôndrio direitodurante a gestação.Durante o internamento, ficou definido que a causa do abscesso hepático foi a infecção das vias biliares.Realizou-se tratamento em unidade de terapia intensiva obstétrica, tendo a paciente sido submetida à drenagem do abscesso hepático e antibioticoterapia. A evolução foi satisfatória e a paciente obteve alta em boas condições. Discussão: o abscesso hepático piogênico durante a gravidez e o puerpério é uma condição extremamente grave, com poucos casos relatados, representando um desafio diagnóstico e terapêutico. Como os achados clínicos e laboratoriais são usualmente inespecíficos, um diagnóstico retardado é possível, aumentando os riscos de morbidade e mortalidade materna em casos não tratados precocemente.

Absceso hepático piógeno secundario a cuerpo extraño / Pyogenic hepatic abscess secondary to a foreign body

El absceso hepático piógeno es una enfermedad secundaria a un foco primario cuyas vías básicas de infección son: vía biliar y el sistema portal. Se presenta el caso de un paciente de 23 años que presenta dolor a nivel de hemiabdomen superior que refiere haber ingerido un alambre en forma de gancho. Sobre la base de los antecedentes y exámenes complementarios se interpreta la posibilidad de un absceso hepático secundario a un cuerpo extraño. Se realizó drenaje del absceso y yeyunotomía para extracción del cuerpo extraño endoluminal. Actualmente, el paciente se encuentra totalmente recuperado(AU)

Pyogenic hepatic abscess is a disease secondary to a primary focus whose basic pathways of infection are the bile duct and the portal system. The case is presented of a 23-year-old patient with pain at the level of the upper hemiabdomen and who reported having ingested a wire in the shape of a hook. Upon the basis of the antecedents and complementary examinations the possibility is interpreted for a hepatic abscess secondary to a foreign body. Drainage of the abscess and jejunostomy were performed to remove the foreign body from the endoluminal system. Currently, the patient is fully recovered(AU)

Absceso hepático piógeno en pediatría: experiencia en un centro pediátrico de referencia / Pyogenic liver abscess in children: clinical experience in a pediatric reference center

Introduction: Liver abscess is a serious and an uncommon pediatric disease. Objective and Method: Description of 20 pediatric patients with liver abscess admitted in "Ricardo Gutierrez" Children’s Hospital, a Tertiary Reference Center of Buenos Aires, between 2009 and 2015. Results: The hospitalization rate was 35/100.000 admissions. Median age was 5 years old, male/female ratio 4/1. Five patients (25%) had predisposing factors. Median days at diagnosis were 12. Features: Fever 100%, prolonged fever 60%, abdominal pain 50%. The majority had leukocytosis and elevated CRP (median 160 mg/L). Liver enzymes were elevated in only 40% of patients. Ultrasonography detected 90%. A single abscess was observed in 60%; localized at right hepatic lobe, 65%. Purulent material was positive in 12/17 (70%) and bacteremia was present in 3/20 (15%). Wide empirical antibiotic therapy was used. Treatment shift was needed in four patients. The median days of intravenous antibiotics were 30 and the median of total treatment were 53. Surgical procedures were performed in 13/20 (65%). Conclusion: Community-acquired methicillin resistant Staphylococcus aureus (CA-MRSA) was the most frequent pathogen, especially in healthy children that associated skin or respiratory illness. Appropriate antibiotic treatment and eventual drainage allows good outcome without sequela or deaths.

Conclusión: Staphylococcus aureus resistente a meticilina de la comunidad (SARM-AC) fue el patógeno predominante, especialmente en niños previamente sanos asociados a un foco cutáneo o respiratorio.

Hepatogastric fistula as a rare complication of pyogenic liver abscess

Hepatogastric fistula following a pyogenic liver abscess is extremely rare, and only a handful of cases have been reported. An 88-year-old female presented with generalized weakness, fever and chills. An abdominal computed tomography scan revealed a 5cm-sized hypodense lesion with internal septa in the left lateral section of the liver. Due to initial suspicion of early liver abscess, she was treated with empirical intravenous antibiotics. Initially, aspiration or drainage of the liver abscess was not performed due to immature lesion characteristics. An ultrasonography-guided percutaneous drainage of the liver abscess was performed 17 days after hospitalization due to a more mature lesion appearance on follow-up imaging. On tubography, contrast media leakage through the fistulous tract was visualized. Surgical management was performed, and she was discharged 2 weeks after surgery.

A Case of Advanced Gastric Cancer Concomitant with Pyogenic Liver Abscess in the Patient with Subtotal Gastrectomy / 대한소화기학회지

The hematogenous spreading of an infectious pathogen via the portal vein from a mucosal injury in the gastrointestinal tract has been considered as one of the pathologic mechanisms of pyogenic liver abscess. Several studies have presented the association between colorectal cancer and pyogenic liver abscess. However, the cases of stomach cancer concomitant with pyogenic liver abscess have rarely been reported in the world. Herein, we present a case of advanced gastric cancer concomitant with pyogenic liver abscess in a patient who previously underwent subtotal gastrectomy due to peptic ulcer perforation.

A Case of Combined Hepatocellular-cholangiocarcinoma Mimicking Pyogenic Liver Abscess

Heterogeneous features of liver cancer can mimic liver abscess. Therefore it is essential to double-check tumor markers in the diagnosis of liver abscess. Herein, we report a case of combined hepatocellular-cholangiocarcinoma (cHC) occurred in an unrecognized chronic hepatitis B patient initially misdiagnosed as liver abscess. A 49-year old male initially presented with chill, right upper quadrant pain, and a liver mass. Mass showed peripheral enhancement in arterial phase of computed tomography, which was not typical for hepatocellular carcinoma (HCC). Strikingly elevated alpha-fetoprotein and fine needle aspirated pathology revealed HCC. Despite discordant image findings he was treated with transarterial chemoembolization. He was treated with sorafenib due to metastatic retrocaval lymphadenopathy afterwards. The mass presumed to be HCC progressed with sorafenib. It was surgically resected and he was finally confirmed as cHC. Discordant tumor markers with presumptive image findings should prompt the suspicion of rare type of primary liver cancer, the cHC.
