Molecular mechanism of Xuebijing in treating pyogenic liver abscess complicated with sepsis / 世界急诊医学杂志（英文）

@#BACKGROUND: Xuebijing (XBJ) can alleviate the inflammatory response, improve organ function, and shorten the intensive care unit (ICU) stay in patients with pyogenic liver abscess (PLA) complicated with sepsis, but the molecular mechanisms have not been elucidated. This study aimed to explore the molecular mechanism of XBJ in treating PLA complicated with sepsis using a network pharmacology approach. METHODS: The active ingredients and targets of XBJ were retrieved from the ETCM database. Potential targets related to PLA and sepsis were retrieved from the GeneCards, PharmGKB, DisGeNet, Online Mendelian Inheritance in Man (OMIM), Therapeutic Targets Database (TTD), and DrugBank databases. The targets of PLA complicated with sepsis were mapped to the targets of XBJ to identify potential treatment targets. Protein-protein interaction networks were analyzed using the STRING database. Potential treatment targets were imported into the Metascape platform for Gene Ontology (GO) functional enrichment and Kyoto Encyclopedia of Genes and Genomes (KEGG) pathway enrichment analyses. Molecular docking was performed to validate the interactions between active ingredients and core targets. RESULTS: XBJ was found to have 54 potential treatment targets for PLA complicated with sepsis. Interleukin-1β (IL-1β), interleukin-6 (IL-6), and tumor necrosis factor (TNF) were identified as core targets. KEGG enrichment analysis revealed important pathways, including the interleukin-17 (IL-17) signaling pathway, the TNF signaling pathway, the nuclear factor-kappa B (NF-κB) signaling pathway, and the Toll-like receptor (TLR) signaling pathway. Molecular docking experiments indicated stable binding between XBJ active ingredients and core targets. CONCLUSION: XBJ may exert therapeutic effects on PLA complicated with sepsis by modulating signaling pathways, such as the IL-17, TNF, NF-κB, and TLR pathways, and targeting IL-1β, IL-6, and TNF.

Massive pleural empyema secondary to amoebic liver abscess in a child / Empiema pleural masivo secundario a absceso hepático amebiano en un niño

Abstract Background: Pleural empyema secondary to a ruptured amoebic liver abscess is a rare complication in the pediatric population. Case report: We report the case of a 13-year-old male with right flank abdominal pain, productive cough with foul-smelling sputum, fever, and respiratory distress. Physical examination revealed breathlessness, decreased vesicular murmur in the right hemithorax, abdominal distension, hepatomegaly, and lower limb edema. Laboratory tests revealed mild anemia, leukocytosis without eosinophilia, elevated alkaline phosphatase, hypoalbuminemia, and positive immunoglobulin G antibodies against Entamoeba histolytica in pleural fluid. He required a chest tube and treatment with metronidazole. After 2 months of follow-up, the abscesses disappeared, and the empyema decreased. Conclusions: Massive pleural empyema secondary to a ruptured liver abscess is a rare complication. The epidemiological link associated with the symptoms and serological tests can help in the diagnosis.

El nexo epidemiológico asociado con la sintomatología y pruebas serológicas pueden ser de ayuda en el diagnóstico.

Burkholderia cepacia causing liver and splenic abscess: Two case reports

Burkholderia cepacia infections are common among immunocompromised patients but multiple reports have shown that it can affect immunocompetent patients also. We are reporting two patients with multiple liver and splenic abscesses caused by Burkholderia cepacia. First case is a 54-year-old diabetic male presenting with fever, abdominal pain, bilateral lower limb weakness, and incontinence of urine. Second case is a 41-year-old male presenting with fever and confusion. Both had liver and splenic abscesses. Pus aspirated from the abscesses grew Burkholderia cepacia. Both responded to cotrimoxazole. Our case report emphasizes growing incidence of Burkholderia cepacia in immunocompetent patients.

An-unusual-complication-of-liver-abscess—hepatoduodenal-fistula

Liver abscess is an intra-abdominal infection characterized by localized pus collection with destruction of hepatic parenchyma. When a liver abscess ruptures and extends into adjacent structures, it leads to development of complications which further increases mortality rate. Involvement of peritoneal, pericardial and pleural cavity are often noted but, extension into gastro-intestinal tract is rare and unusual; with only a limited number of cases reported, we present a recently encountered case of liver abscess. The abscess was found to be complicated by formation of fistulous tract with duodenum.

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.

Diagnóstico por imagen de abscesos hepáticos y pulmonares por estreptococos del grupo viridans. Presentación de caso / Imaging diagnosis of liver and lung abscesses due to viridans streptococci. Case presentation

Resumen El Streptococcus viridans es conocido más comúnmente como agente infeccioso en las endocarditis, sin embargo, poco se conoce sobre su potencial infeccioso en otros órganos o sistemas, donde ha demostrado una elevada mortalidad. El reconocimiento del Streptococcus viridans como agente productor de abscesos en otras localizaciones como a nivel hepático o pulmonar, permitirá un diagnóstico oportuno mediante los distintos métodos de imagen, reduciendo las graves consecuencias para el paciente y los tiempos de hospitalización. Se presenta el caso de un paciente del sexo masculino de 33 años de edad sin antecedentes crónico degenerativos, que inició con sintomatología 7 meses previos a su ingreso, con fiebre intermitente, fatiga, astenia, anorexia y pérdida de peso. A la exploración física presentó dolor a la palpación media y profunda en hipocondrio derecho, en el panel de laboratorios presentó llamativa neutrofilia, en la tomografía de tórax y abdomen se mostró lesión cavernomatosa en pulmón y quistes complicados hepáticos, a los cuales se les realizó drenaje percutáneo guiado por ultrasonido, con envío de muestras a cultivo con resultado positivo para Streptococcus viridans, lo que permitió brindar el tratamiento dirigido al paciente, y que remitiera la enfermedad.

Abstract Streptococcus viridans is more commonly known as an infectious agent in endocarditis, however, little is known about its infectious potential in other organs or systems, where it has shown high mortality. The recognition of Streptococcus viridans as an abscess-producing agent in other locations, such as the liver or lungs, will allow timely diagnosis using different imaging methods, reducing serious consequences for the patient and hospitalization times. We present the case of a 33-year-old male patient with no chronic degenerative history, who started symptoms 7 months prior to admission, with intermittent fever, fatigue, asthenia, anorexia and weight loss, on physical examination he presented pain at the medium and deep palpation in the right hypochondrium, in the laboratory panel I present striking neutrophilia, in the tomography of the thorax and abdomen a cavernous lesion in the lung and complicated hepatic cysts are shown, to which percutaneous drainage guided by ultrasound is performed, with sending of cultured samples with a positive result for Streptococcus viridans. Thus, allowing treatment to be provided to the patient, thereby achieving remission of the disease.

Microabscesos hepáticos colangiolares secundarios a coledocolitiasis

Los abscesos hepáticos son colecciones supurativas encapsuladas dentro del parénquima hepático, las cuales generalmente se encuentran infectadas por bacterias. Se forman por diferentes mecanismos, una de ellas es la secundaria a la infección de las vías biliares, colangitis aguda, la misma que en su evolución natural puede progresar a una infección severa e incluso a sepsis o choque séptico y es por ello que requiere un diagnóstico y tratamiento adecuados. La litiasis biliar puede complicarse con colangitis aguda tras la obstrucción al flujo de salida de la bilis con posterior infección, generalmente bacteriana, no solo del árbol biliar sino también del parénquima hepático. Se presenta el caso clínico de una paciente mujer joven que cursó con microabscesos hepáticos colangiolares tras un evento de coledocolitiasis no tratado oportunamente.

Hepatic abscesses are suppurative collections encapsulated within the liver parenchyma, which are generally infected by bacteria. They are formed by different mechanisms, one of them is secondary to bile duct infection, acute cholangitis, which in its natural history can progress to severe infection and even sepsis or septic shock and that is why it requires a proper diagnosis and treatment. Gallstones can be complicated by acute cholangitis after bile outflow obstruction with subsequent infection, usually bacterial, not only of the biliary tree but also of the liver parenchyma. We present the clinical case of a young female patient who presented with cholangiolar hepatic microabscesses after an event of choledocholithiasis not treated in a timely manner.

Changes in clinical and CT manifestations related to liver abscesses in patients with vs. without basic diabetes mellitus before and after CT-guided interventional therapy: An observational study

Abstract Purpose: To explore differences in the changes of clinical and CT manifestations related to liver abscess before and after CT-guided interventional therapy between patients with and without Diabetes Mellitus (DM). Materials and methods: Fifty-eight consecutive patients with liver abscesses were retrospectively enrolled in this study. All patients underwent upper abdominal contrast-enhanced CT scans before and after CT-guided interventional therapy. They were divided into two groups including the DM group (n = 30) and the Non-DM group (n = 28) if the liver abscess occurred in patients with and without DM, respectively. The changes in the clinical and CT manifestations related to liver abscess after CT-guided interventional therapy in both groups were statistically analyzed. Results: After CT-guided interventional therapy, the length of hospital stay, white blood cell recovery time and drainage tube removal time in the DM group were longer than in the Non-DM group (all p-values < 0.05). The incidence of postoperative complications in the DM group was higher than in the Non-DM group (p < 0.05). As shown on CT, the postoperative reduced percentage of maximum diameter of abscess cavity and the reduction rate of edema band surrounding the liver abscess in the DM group were smaller than in the Non-DM group (both p-values < 0.05). The time intervals of the previous characteristic changes on CT before and after interventional therapy in the DM group were longer than in the Non-DM group (all p-values < 0.05). Conclusions: The liver abscesses patients with DM could not have a faster recovery and better therapeutic effect than those without DM after the CT-guided interventional therapy.

Clinical features of bacterial liver abscess in the context of coronavirus disease 2019 in Changchun， China / 临床肝胆病杂志

ObjectiveTo investigate the clinical and epidemiological features of patients with bacterial liver abscess during the outbreak of coronavirus disease 2019 （COVID－19） in Changchun， China. MethodsA retrospective analysis was performed for 37 411 patients who were discharged from The First Hospital of Jilin University from March 1 to June 30 in 2022， and finally 135 patients with bacterial liver abscess were included for analysis. Related clinical data were collected to summarize their clinical features， and these patients were compared with the patients with bacterial liver abscess in 2019－2021 in terms of disease onset and pathogen. The Kruskal－Wallis H test was used for comparison of continuous data between multiple groups， and the chi－square test was used for comparison of categorical data between multiple groups. ResultsThe patients with bacterial liver abscess accounted for 0.36% of the patients admitted to our hospital during the same period of time， which showed varying degrees of increase compared with the previous years （χ2=32.081， P<0.001）. The 135 patients with bacterial liver abscess had a mean hospital stay of 11 （6－18） days， which was longer than that in the previous years （H=9.223， P=0.026）. The patients with bacterial liver abscess had higher levels of white blood cell count and C－reactive protein （CRP） than the previous years （H=14.150 and 8.736， P=0.003 and 0.033）. Among the 135 patients， 69 （51.11%） received blood culture， and the results showed sterile growth （59.42%）， Klebsiella pneumoniae （30.43%）， Escherichia coli （4.35%）， Bacteroides fragilis （1.45%）， Enterococcus faecium （1.45%）， Staphylococcus epidermidis （1.45%）， and Klebsiella oxytoca （1.45%）. Among the 135 patients， 90 （66.67%） received pus culture， and the results showed Klebsiella pneumoniae （72.22%）， sterile growth （14.44%）， Escherichia coli （4.44%）， Enterococcus faecium （2.22%）， Pseudomonas aeruginosa （2.22%）， Acinetobacter baumannii （1.11%）， Klebsiella aerogenes （1.11%）， Klebsiella oxytoca （1.11%）， and Enterococcus casseliflavus （1.11%）. Of all 135 patients， 127 （94.07%） were improved and cured after anti－infective therapy and ultrasound－guided abscess puncture and drainage， and 3 patients （2.22%） died during hospitalization. ConclusionDuring the outbreak of COVID－19 in Changchun， there are increases in the number of patients with liver abscess in our hospital， the length of hospital stay， and the levels of white blood cell count and CRP， with Klebsiella pneumoniae as the main pathogen， and most patients are improved after treatment.

Clinical analysis of 12 cases of invasive Klebsiella pneumoniae liver abscess syndrome / 中华全科医师杂志

Objective:To analyze the clinical features of patients with invasive Klebsiella pneumoniae liver abscess syndrome (IKLAS). Methods:The clinical data of 12 patients diagnosed as IKLAS in Zhuzhou Central Hospital from January 2020 to January 2023 were retrospectively analyzed.Results:Among 12 patients there were 6 males and 6 females with an mean age of 65.3±12.2 years (49-90). Nine patients were complicated with type 2 diabetes. The main clinical manifestations were fever ( n=9), chill ( n=6), shiver ( n=4), nausea and vomiting ( n=2), upper abdominal pain ( n=2), fatigue and anepithymia ( n=2), cough and expectoration ( n=1), disturbance of consciousness ( n=1) and hemoptysis ( n=1). The leukocyte count was increased in 8 cases, lymphocyte count decreased in 10 cases, and platelets count decreased in 3 cases. C-reactive protein and procalcitonin levels were elevated, while serum albumin levels were lowered in all patients. The alanine aminotransferase (ALT) and aspartate aminotransferase (AST) were increased in 7 cases each. Liver abscess was located in the right lobe in 8 cases, in the left lobe in 1 cases, and in both lobes in 3 cases. There were 7 patients with single abscess, and 5 patients with multiple abscesses. The etiology was confirmed by liver pus culture ( n=10) and blood culture ( n=5), respectively. The main sites of invasion were lung and blood stream ( n=10 and n=5, respectively). The majority of Klebsiella pneumoniae isolates were antibiotic sensitive strains and the overall drug resistance rate was relatively low. All patients were given antibiotics, and 10 of them also received liver abscess puncture drainage. After treatment, 11 patients were discharged, and 1 died of septic shock. Conclusions:Patients with IKLAS exhibit diverse clinical symptoms, most patients are complicated with diabetes, and the main sites of invasion are in the lungs and blood stream. Timely diagnosis, active screening of extrahepatic infection sites, effective drainage of abscess and appropriate antibiotic treatment can improve the survival of patients.

Effect of diabetes on sepsis in patients with pyogenic liver abscess / 中华肝胆外科杂志

Objective:To study the effect of diabetes mellitus (DM) on sepsis in patients with pyogenic liver abscess (PLA).Methods:The clinical data of 116 patients with PLA treated in the Affiliated Hospital of Jiangnan University from January 2021 to May 2022 were retrospectively analyzed, including 64 males and 52 females, aged (62.3±12.6) years old. Patients were divided into DM group ( n=56) and non-DM group ( n=60), which were also divided into the sepsis group ( n=29) and the non-sepsis group ( n=87). The clinical features were compared among the groups, the risk factors of PLA complicated with sepsis were analyzed by multivariate logistic regression. Mediation model was used to analyze how DM affects the development of sepsis. Results:Compared with the non-DM group, patients in DM group had higher incidences of hypertension and acute physiology and chronic health evaluation II, a higher proportion of blood neutrophil count, a higher serum levels of triglyceride, urea nitrogen, fasting blood glucose and glycated hemoglobin at admission. The DM group also higher incidences of hypoproteinemia, pleural effusion, and sepsis, with longer hospital stay and higher hospitalization cost (all P<0.05). The levels of hemoglobin, albumin and hematocrit were lower in DM group (all P<0.05). Multivariate logistic regression analysis showed that comorbidity of DM ( OR=3.431, 95% CI: 1.245-9.455) and abscess with a larger diameter ( OR=1.664, 95% CI: 1.258-2.220) were associated with a higher risk of developing sepsis (all P<0.05). Mediation model showed that neutrophil count and triglyceride were the mediating variables of sepsis in patients with PLA. Conclusion:Comorbidity of diabetes is an independent risk factor of developing sepsis in patients with pyogenic liver abscess. Diabetes may induce sepsis by affecting the neutrophils and triglyceride.

Clinical characteristics and prognosis of bacterial liver abscess in patients with diabetes mellitus / 中华传染病杂志

Objective:To compare the clinical characteristics and prognosis of bacterial liver abscess in patients with or without diabetes mellitus (DM), to provide a reference for clinical diagnosis and treatment.Methods:Patients with bacterial liver abscesses hospitalized in Tongren Hospital, Shanghai Jiao Tong University School of Medicine from January 2016 to August 2021 were enrolled, and their clinical data were collected. The patients were divided into diabetic and non-diabetic groups for comparison according to whether they had comorbid DM. Statistical analysis was performed by chi-square test or Fisher′s exact test, and multivariate logistic regression analysis.Results:A total of 131 patients with bacterial liver abscesses were included, including 47 cases in the diabetic group and 84 cases in the non-diabetic group. The percentages of platelet count <100×10 9/L, C-reactive protein>10 mg/L, and total bilirubin>17.5 μmol/L were lower in the diabetic group than that in the non-diabetic group, and the differences were all statistically significant ( χ2=3.90, 6.44 and 5.56, respectively, all P<0.05). The percentage of multiple abscesses in the diabetic group was 10.6%(5/47), which was lower than 29.8%(25/84) in the non-diabetic group, and the difference was statistically significant ( χ2=6.24, P=0.012). The positive rate of pus culture for Klebsiella pneumoniae was 64.9%(24/37) in the diabetic group, which was higher than 41.5%(27/65) in the non-diabetic group, with a statistically significant difference ( χ2=5.13, P=0.023). The incidences of pleural effusion and abscesses at other sites in the diabetic group were 29.8%(14/47) and 10.6%(5/47), respectively, which were both higher than 14.3%(12/84) and 1.2%(1/84) in the non-diabetic group, respectively, and the differences were statistically significant ( χ2=4.55, Fisher′s exact test, both P<0.05). The proportion of hospital stays>21 d was 34.0%(16/47) in the diabetic group, which was higher than 16.7%(14/84) in the non-diabetic group, with a statistically significant difference ( χ2=5.15, P=0.023). DM (odds ratio ( OR)=2.654, 95% confidence interval ( CI) 1.020 to 6.907, P=0.046) and abscess maximum diameter>10 cm ( OR=11.045, 95% CI 4.493 to 27.154, P<0.001) were significant risk factors for hospital stay>21 d. Conclusions:Bacterial liver abscesses combined with DM are more common with single abscess, a higher rate of Klebsiella pneumoniae infection, and more likely to develop pleural effusions and abscesses at other sites. Liver abscesses>10 cm in maximum diameter and comorbid DM would prolong hospital stay.

Clinical features of patients with malignant tumor-related pyogenic liver abscess / 临床肝胆病杂志

Objective To investigate the clinical features of malignant tumor-related pyogenic liver abscess (PLA), and to provide a basis for early judgment of disease progression and timely and effective treatment. Methods A retrospective analysis was performed for the clinical data of 371 patients with PLA who were admitted to the Second Affiliated of Air Force Medical University, from March 2005 to July 2018, among whom 34 patients with malignant tumor-related PLA were enrolled as tumor group, and after matching for time and at a ratio of 1∶2, 70 patients without malignant tumor-related PLA were enrolled as non-tumor group. Clinical features were compared between the two groups. The group t -test was used for comparison of normally distributed continuous data between groups, and the Mann-Whitney U test was used for comparison of non-normally distributed continuous data between groups; the chi-square test or the Fisher's exact test was used for comparison of categorical data between groups. Results In the tumor group, there were 22 patients with hepatobiliary tumor (64.7%), 7 patients with gastrointestinal tumor (20.6%), and 5 patients with non-gastrointestinal tumor (14.7%). Compared with the non-tumor group, the tumor group had a significantly higher proportion of patients with a history of abdominal surgery (44.1% vs 7.1%, χ 2 =20.142, P 16 (44.1% vs 15.7%, χ 2 =9.846, P =0.002). Compared with the non-tumor group in terms of laboratory examination, the tumor group had a significantly lower level of albumin [(27.2±5.2) g/L vs (30.8±2.6) g/L, t =-3.131, P =0.002] and a significantly higher level of total bilirubin [54(13~313) μmol/L vs 33(7~96) μmol/L, U =1 816.0, P < 0.001]. Escherichia coli was the main pathogen in the tumor group (23.5%), while Klebsiella pneumonia was the main pathogen in the non-tumor group (23.5%), and compared with the non-tumor group, the tumor group had a significantly higher proportion of patients infected with more than two types of bacteria (11.8% vs 2.8%). Radiological examination showed that the tumor group had a significantly higher proportion of patients with multiple abscesses than the non-tumor group (47.1% vs 24.3%, χ 2 =5.479, P =0.019). Compared with the non-tumor group, the tumor group had a significantly longer mean length of hospital stay ( U =1 728.5, P < 0.001) and a significantly higher treatment failure rate ( P =0.005). Conclusion Patients with malignant tumor-related PLA often have hepatobiliary tumor, with Escherichia coli as the main pathogen. Abscesses at multiple sites are common, and patients tend to have a poor prognosis. Appropriate antibiotics combined with percutaneous drainage should be used in clinical practice, and for the high-risk population, the threshold for surgical intervention can be lowered to reduce mortality.

Absceso hepático por Enterobius vermicularis como diagnóstico diferencial de metástasis hepática en cáncer colorrectal, reporte de caso / Liver Abscess Caused by Enterobius vermicularis as a Differential Diagnosis for Liver Metastasis in Colorectal Cancer, Case Report

Resumen Introducción: el cáncer colorrectal es la cuarta causa de mortalidad asociada con cáncer en el mundo. La identificación de las metástasis de este tumor en el momento prequirúrgico es cada vez más frecuente por los estudios imagenológicos con los que se cuenta en la actualidad. Presentamos el caso de una paciente con infección por Enterobius vermicularis que simula la presencia de metástasis hepáticas. Presentación del caso: se presenta el caso de una paciente femenina proveniente del área rural, con dolor abdominal de 1 año de evolución asociado con hemorragia de vías digestivas bajas y pérdida de peso. Las imágenes y estudios endoscópicos muestran una lesión tumoral en el colon sigmoide con biopsias que reportan adenocarcinoma de colon sigmoides, además de lesiones hepáticas sugestivas de malignidad. Se llevó a resección anterior de recto y sigmoides con anastomosis alta y toma de biopsias hepáticas, que descartaron la malignidad e informaron la presencia de infección hepática por E. vermicularis. Discusión: La infección por E. vermicularis a nivel hepático presentada en el caso es poco frecuente, dicha infección puede simular la presencia de metástasis hepáticas, por lo cual debe tenerse en cuenta como diagnóstico diferencial de enfermedad metastásica de cáncer colorrectal.

Abstract Introduction: colorectal cancer is the fourth leading cause of cancer-related mortality worldwide. The identification of the metastases of this tumor in the preoperative stage is increasingly frequent due to the imaging studies currently available. We present the case of a patient with an infection caused by Enterobius vermicularis that simulates the presence of liver metastases. Case presentation: a female patient from a rural area showing a one-year abdominal pain evolution associated with lower gastrointestinal tract bleeding and weight loss. Endoscopic imaging and studies displayed a tumor lesion in the sigmoid colon, with biopsies reporting sigmoid colon adenocarcinoma and liver lesions suggesting malignancy. Anterior resection of the rectum and sigmoid was performed with high anastomosis and liver biopsies, which ruled out malignancy and reported the presence of liver infection by E. vermicularis. Discussion: in this case, the hepatic E. vermicularis infection was rare. This infection can simulate the presence of liver metastases; therefore, it should be considered a differential diagnosis of metastatic colorectal cancer.

"A": initial nonoperative management, laparoscopic lavage due to symptomatic hemoperitoneum, percutaneous drainage of liver abscess, catheter replacement and ERCP due to persistent biliary fistula. "B": initial damage control surgery without liver resections, percutaneous drainage of liver abscess and catheter replacement. "C": initial nonoperative management, laparoscopic lavage due to symptomatic hemoperitoneum, percutaneous drainage of liver abscess and catheter replacement. None of the patients died. Conclusion: These cases summarize the use of different management modalities of blunt hepatic trauma and the possibility of minimally invasive management of the complications.

Diagnostic approach of liver abscess

Liver abscess is an infection of parasitic or bacteria into the liver parenchyma which causes encapsulation of suppurative material surrounded by inflammatory tissue. Liver abscess is an important health problem especially in low-middle income countries. It is not easy to diagnose liver abscess due to non-specific clinical signs. This case report, we presenteda 46-year-old man who was hospitalized with suspected pulmonary infection. However, in the course of the patient's disease, we found a liver abscess.

Gas Under Right Hemidiaphragm: A Rare Presentation of Unruptured Liver Abscess

A perforated liver abscess mimics hollow viscus perforations. It may be accompanied by pneumoperitoneum and peritonitis. A hollow viscus perforation appears to be the most common cause of gas under diaphragm. In about 10% of the cases, it can be due to rare abdominal and extra-abdominal causes. One of the causes could be intra-abdominal infection caused by gas-forming organisms. We are reporting a rare case of pneumoperitoneum resulting from an unruptured liver abscess in an old male with no comorbidity. An unruptured pyogenic right lobe liver abscess in a 70-year-old male was accompanied by X-ray flat plate abdomen features suggestive of free gas under the right hemidiaphragm. Culture of the pus drained from liver abscess grew Klebsiella sensitive to piperacillin and tazobactam, and antibiotic treatment was administered.

Disseminated tuberculosis presenting as cardiac tamponade—Uncommon presentation in common disease

Tuberculosis is the most common infection in India, and its incidence accounts for approximately one-fifth of the global burden. Cardiac tamponade resulting from the liver abscess with subdiaphragmatic rupture communicating with pericardial cavity presenting as disseminated tuberculosis is uncommon. Here, we reported a case of a 63-year-old man who presented with the shortness of breath for 3 days with orthopnea. Imaging studies reveal pericardial effusion, left liver lobe loculated lesion, and enlarged right supraclavicular lymph node. Further image-guided pericardiocentesis, left liver lobe aspiration cytology, and right supraclavicular lymph node cytology reveal granulomatous inflammation with positive acid-fast bacillus in the liver aspirate. The patient was managed in the emergency room symptomatically initially and was then successfully treated with antituberculous treatment.

Demographic, Clinical, Laboratory and Management Profile in Patients of Amoebic Liver Abscess from Northern India

Background: Amoebic liver abscess (ALA) is a serious extra-intestinal manifestation of amoebiasis and a major problem in developing countries. Due to rapid urbanization, improved sanitation and hygiene in India, there has been a shift in disease epidemiology towards non-communicable disease, but recent changes in epidemiological and clinical pattern in ALA are not well studied. Aim: To evaluate recent demographic, clinical, laboratory and management profile in patient with ALA. Methods: It is a prospective observational study conducted in the Department of Gastroenterology, SMS medical college, Jaipur, Rajasthan from June 2018 to December 2020. A predesigned semi structured questionnaire consisting of socio-demographic factors, risk factors, clinical, laboratory and management profile was used to collect data. Result: A total 508 patients of amoebic liver abscess were analysed. Median age of presentation was 40 years, majority were males (90.4%) with chronic alcoholism (44.1%) and belonging to lower socio-economic class. Abdominal pain, fever and anorexia were the most common symptoms. A majority had right lobe involvement (77.6%) and solitary abscess in 67.5%. Most of the small liver abscesses (68%) were managed by medical treatment alone. Percutaneous needle aspiration was done in 62.6% patients, mostly for abscess size 5-10 cm (93%) with 90% success. A total of 24.6% patients underwent percutaneous catheter drainage, all successfully done. Intraperitoneal rupture was seen in 10% patient. Mortality was 1.5%. Conclusion: This is one of the largest cohorts of ALA which shows that a majority of cases are males from lower socioeconomic status with history of significant alcohol intake. Early initiation of a combined therapeutic approach leads to early symptomatic improvement, fewer complications and better outcomes.

Liver abscess: A case study

Liver abscess is a suppurative lesion in the liver formed as a result of invasion and multiplication of microorganisms which gain access by entering directly from an injury through the blood vessels or by the biliary ductal system/ septicemia, direct infection latrogenic & cryptogenic. It can be diagnosed by comparing the lab values with the diseased condition such as hemoglobin (10.9g/dl), neutrophils (83), ESR (120mm), Serum albumin (3.4g/dl), ALP (245U/L), Gamma GT (347U/L), prothrombin time (25.2 seconds), APTT (37.9 seconds). By performing the above tests, we have confirmed that the patient was suffering from liver abscess.
