Pyogenic liver abscess – 20 years' experience

BACKGROUND AND AIMS: Our aim is to give an audit of our experience over the past two decades in the form of a retrospective study. PATIENTS/METHODS: In two equal periods between 01.01.1982 and 31.03.2001, 56 patients (37 males and 19 females) with pyogenic liver abscess were treated. Image-guided percutaneous drainage was performed in 22.2%/20.6% of the patients; the remainder were treated with open drainage with or without biliary tract reconstruction and liver resection. For antibiotic perfusion of the liver an umbilical vein cannula was inserted in 40.7%/24.1%. Microbiological findings, types of therapy, complications and mortality, etiology, patient characteristics, symptoms, and laboratory data were investigated. The results in the two groups were compared and analyzed statistically. RESULTS: The most common cause of abscess, biliary disease, was seen more often in the second period. Solitary liver abscesses were more frequent. The only characteristic biochemical finding was an elevated alkaline phosphatase level. There were more positive cultures in the second period (70.4%/79.3%), and the number of Escherichia coli or Enterobacter aerogenes infections also increased. In the first period the mortality was 18.5%, whereas in the second no patients were lost. CONCLUSION: We suggest the importance of individualized therapy based on an early and exact diagnosis. The first treatment step should be image-guided drainage, but under well-defined circumstances open drainage can also be performed with good results.     

Pyogenic liver abscess: an audit of 10 years' experience and analysis of risk factors.

BACKGROUND/AIMS: Despite continuous improvement in image modalities, availability of potent antibiotics and advancement in the knowledge and treatment of pyogenic liver abscess, mortality remains high. The high mortality rate has underlined the important role of prognostic factors and prompts a number of studies to identify the risk factors. The present study aims to audit our experience in managing patients with pyogenic hepatic abscess during the period of 1989-1999, and to document changes in etiology, bacteriology and outcome, and to identify any risk factor associated with mortality. METHODS: One hundred and thirty-three patients with pyogenic hepatic abscess were studied to determine the demographic characteristics, clinical features, laboratory, bacteriological findings, methods of treatment, final outcome and risk factor analysis. All patients were treated with parenteral antibiotics. One hundred and twelve patients were subjected to ultrasound-guided percutaneous aspiration of the abscess. A percutaneous drainage catheter was inserted after aspiration in all patients. Laparotomy was done in 21 patients. RESULTS: The overall hospital mortality rate was 6% (8/133). Biliary tract disease was the most frequently identified cause. Leukocytosis, hypoalbuminemia and hyperbilirubinemia were common laboratory findings. The most common microorganism cultured was Klebsiella pneumoniae. The most common concomitant disease was diabetes mellitus. On univariate analysis, large abscess, diabetes mellitus and sepsis were significantly associated with hospital mortality. On multivariate logistic regression analysis, the presence of sepsis (p = 0.0031) was found to be an independent risk factor. CONCLUSIONS: In addition to early diagnosis and prompt treatment, making every effort to treat patients with adverse prognostic factors and systemic complications, the hospital mortality rate will be decreased significantly.     

Pyogenic liver abscess

The objective of this study was to investigate and report changes in presentation, management and outcome of patients with pyogenic liver abscess (PLA). Between 01.01.1995-31.12.1999, 27 patients with PLA were treated in the General Surgical Service of the Fundeni Clinical Hospital. The incidence of cryptogenic abscesses was dominant (55.5%). The symptoms and the biological status are frequently nonspecific. The CT scan and echographic examination sensibility in the diagnosis of the PLA was 89.5% and 78.3%. The aerobe germs are most involved. All patients received antibiotic treatment in preoperative as in postoperative period. The surgical treatment was performed in 24 patients: in 9 patients (33.3%), the abscess was surgically evacuated and drained and in 15 patients (55.5%), a liver resection was performed. Percutaneous catheter drainage under CT or echo-guidance was performed in three patients (11.1%). The clinical evolution was good in 21 patients (77.7%). There was four complications (14.8%) and two death (7.4%). Although with a better prognostic, the PLA remains an important pathology.

Pyogenic liver abscess

Experience with 34 patients with pyogenic liver abscess is reviewed to evaluate the impact of percutaneous drainage and duration of antibiotic therapy on results of treatment. Patients with shock, adult respiratory distress syndrome, disseminated intravascular coagulation, jaundice, severe hypoalbuminemia, and diabetes had a poor prognosis. Percutaneous drainage was used successfully in 4 of 6 patients, but its use did not affect mortality rate or length of hospital stay. Percutaneous drainage may be the procedure of choice for selected patients. Half of our patients received antibiotics for 2 weeks or less with no abscess recurrences in this group. Long-term antibiotics may not be necessary after adequate surgical or percutaneous abscess drainage.

Resumen Se revisó la experiencia con treinta y cuatro pacientes con absceso piogénico del hígado con el fin de evaluar el impacto del drenaje percutáneo y la duración de la terapia antibiótica sobre los resultados del tratamiento. Los pacientes con shock, síndrome de dificultad respiratoria del adulto, coagulación diseminada intravascular, ictericia, hipoalbuminemia severa, y diabetes exhibieron un mal pronóstico. El drenaje percutáneo fue utilizado exitosamente en 4 de 6 pacientes pero su uso no modificó la tasa de mortalidad ni la duración de la hospitalización. El drenaje percutáneo puede ser el procedimiento de elecctión en casos seleccionados. La mitad de nuestros pacientes recibió antibióticos por 2 semanas o menos, sin que se presentara recurrencia del absceso. La antibioticoterapia a largo plazo puede ser innecesaria una vez realizado un adecuado drenaje, quirúrgico o percutáneo, del absceso.

Résumé Nous avons analysé notre expérience des abcès hépatiques pyogènes pour déterminer l'influence du drainage percutané et de la durée de l'antibiothérapie sur les résultats du traitement. On observait un mauvais pronostic chez les patients ayant eu un choc, un syndrome de détresse respiratoire de l'adulte, une coagulopathie vasculaire disséminée, un ictère, une hypoalbuminémie et/ou un diabète. Le drainage percutané a été utilisé avec succès chez 4 des 6 patients mais n'a influencé ni la mortalité ni la durée d'hospitalisation. Le drainage percutané a été le procédé de choix chez un groupe de patients sélectionnés. La moitié des patients avaient reçu des antibiotiques 2 semaines ou moins sans récidive. Une utilisation prolongée des antibiotiques n'est pas nécessaire si l'abcès a été correctement drainé chirurgicalement ou par voie percutanée.

     

Pyogenic liver abscess: an improvement in prognosis

Forty-six patients with pyogenic liver abscess have been treated at Paul Brousse Hospital between 1966 and 1986. The overall mortality was 24 per cent, all 11 deaths occurring in 24 patients seen prior to 1978 when there was often a considerable delay in the diagnosis of liver abscess (mean 90 +/- 71 days). In seven patients the diagnosis was not made until post-mortem examination. The mainstay of treatment was surgical drainage. Since 1978 high resolution imaging techniques for the liver, and in particular ultrasound, have been available. The diagnostic delay has been significantly reduced (mean 28 +/- 20 days, P less than 0.01). Patients are receiving definitive treatment at an earlier stage in the evolution of the disease process, with fewer established complications prior to treatment (P less than 0.05). Percutaneous drainage under ultrasound control is the preferred initial drainage procedure in high-risk patients. There have been no deaths in 22 patients treated for pyogenic liver abscess since 1978 (P less than 0.001).     

Pyogenic liver abscess: Changing patterns in approach

AIM: To define optimum management of the pyogenic liver abscess and assess new trends in treatment.METHODS: One hundred and sixty nine patients with pyogenic liver abscess managed at Sher-i-Kashmir Institute of Medical Sciences, Srinagar, Kashmir (India) from July 2001 to August 2006 were studied to evaluate and define the optimum treatment.RESULTS: Mortality in the surgically treated group of patients was 9.4% (12/119), while those treated non-surgically had a fatality rate of 16.66% (7/42). Multiple liver abscesses treated surgically had a surprisingly low mortality of 30%. The biliary tract (64.97%) was the most common cause of liver abscess. Multiple abscesses, mixed organisms and abscess complications are all associated with a significantly increased mortality. However, the lethality of the primary disease process was the most important factor in determining survival.CONCLUSION: Transperitoneal surgical drainage and antibiotics are the mainstay of treatment. Percutaneous drainage is recommended for high risk patients only.     

Pyogenic liver abscess. Modern treatment

Historically, open surgical drainage has been the treatment of choice for pyogenic liver abscess. The records of 54 patients with pyogenic liver abscess were reviewed to determine whether earlier diagnosis with current imaging tests and definitive treatment with antibiotics, aspiration, or catheter drainage was an effective alternative to open drainage. Twenty-nine patients were treated with broad-spectrum antibiotics and diagnostic aspiration. Twenty-three (79%) recovered uneventfully, and six required catheter or operative drainage. Twenty-three patients (including five who failed aspiration) underwent drainage with percutaneously placed catheters. Nineteen (83%) recovered; four required open surgical drainage. Of seven patients who required open surgical drainage, six recovered. One (2%) of the 54 patients died following failed aspiration and catheter and surgical drainage. Four patients were successfully treated with antibiotics alone without aspiration. These results confirm that pyogenic liver abscess can be successfully treated with broad-spectrum antibiotics and aspiration or percutaneous catheter drainage. Open surgical drainage is reserved for patients in whom treatment fails or who require celiotomy for concurrent disease.     

Pyogenic liver abscess: Multivariate analysis of risk factors

Seventy-three patients with pyogenic liver abscess during the year 1978–1988 were studied in the Kaohsiung Medical College Hospital. The overall mortality rate was 19.2% in this study. By using univariate analysis, it was revealed that clinical jaundice, pleural effusion, bilobar abscess, profound hypoalbuminemia (<2.5 g/dl), hyperbilirubinemia (>2 mg/dl), elevated level of serum AST (>100 IU/L), alkaline phosphatase (>150 IU/L), and marked leukocytosis (>20,000 mm³) were associated with a higher mortality rate. Multivariate stepwise logistic regression analysis detected only 3 factors of marked leukocytosis (>20,000 mm³), profound hypoalbuminemia (<2.5 g/dl), and presence of pleural effusion with independent significance in predicting mortality. Meanwhile, it was also revealed that the laboratory data could not predict a risk factor to mortality unless they became markedly abnormal.

Resumen Setenta y tres pacientes con absceso hepático piógeno manejados en el período 1978–1988 fueron estudiados en el Hospital del Colegio Médico de Kaohsiung. La mortalidad global fue de 19.2 por ciento. Mediante el análisis univariable, se encontró que la ictericia clínica, la efusión pleural, los abscesos bilobares, la hipoalbuminemia profunda (<2.5 g/dl), la hiperbilirrubinemia (>2 mg/dl), la elevación del nivel de la AST sérica (>100 IU/L), la elevación de la fosfatasa alcalina (>150 IU/L), y la leucocitosis pronunciada (>20,000 mm³) aparecieron como factores asociados con una alta tasa de mortalidad. El análisis multivariable de regresión logística détectó solo 3 factores con significatión independiente en cuanto a la predictión de mortalidad: leucocitosis pronunciada (>20,000 mm³), hipoalbunemia profunda (<2.5 g/dl), y efusión pleural. El estudio también reveló que los datos de laboratorio no tienen capacidad para predecir riesgo a menos que los valores se hagan notoriamente anormales.

Résumé Soixante-treize patients ayant un abcès pyogène du foie observé pendant les années 1978–1988 ont été étudiés à l'Hôpital de l'Ecole de Médecine Kaohsiung. La mortalité globale a été de 19.2%. En analyse monofactorielle, un plus fort taux de mortalité a été noté lorsqu'étaient associés ictère clinique, épanchement pleural, abcès dans les deux lobes, hypo-albuminémie (<2.5 g/dL), bilirubinémie (>2 mg/dL), sérum AST (>100 IU/L), phosphatases alcalines (>150 UI/L), et hyperleucocytose (>20,000 mm³). L'analyse multifactorielle pas à pas n'a détecté que 3 facteurs, hyperleucocytose, hyperleucocytose (>20,000 mm³), hypoalbuminémie (<2.5 g/dL), et l'existence d'un épanchement pleural, ayant une valeur significative dans la prédiction de mortalité. Il a été démontré qu'un seul facteur de risque n'avait de valeur prédictive que lorsque sa valeur était très anormale.
