RESUMO
BACKGROUND: To evaluate complications and identify risk factors for adverse events in patients undergoing high-dose-rate interstitial brachytherapy (iBT). MATERIAL AND METHODS: Data from 192 patients treated in 343 CT- or MRI-guided interventions from 2006-2009 at our institution were analyzed. In 41 %, the largest tumor treated was ≥ 5 cm, 6 % of the patients had tumors ≥ 10 cm. Prior to iBT, 60 % of the patients had chemotherapy, 22 % liver resection, 19 % thermoablation or transarterial chemoembolization (TACE). Safety was the primary endpoint; survival data were obtained as the secondary endpoints. During follow-up, MRI or CT imaging was performed and clinical and laboratory parameters were obtained. RESULTS: The rate of major complications was below 5 %. Five major bleedings (1.5 %) occurred. The frequency of severe bleeding was significantly higher in patients with advanced liver cirrhosis. One patient developed signs of a nonclassic radiation-induced liver disease. In 3 patients, symptomatic gastrointestinal (GI) ulcers were detected. A dose exposure to the GI wall above 14 Gy/ml was a reliable threshold to predict ulcer formation. A combination of C-reactive protein ≥ 165 mg/l and/or leukocyte count ≥ 12.7 Gpt/l on the second day after the intervention predicted infection (sensitivity 90.0 %; specificity 92.8 %.) Two patients (0.6 %) died within 30 days. Median overall survival after the first liver treatment was 20.1 months for all patients and the local recurrence-free surviving proportion was 89 % after 12 months. CONCLUSIONS: Image-guided iBT yields a low rate of major complications and is effective.

Data regarding prognostic factors for patients with septic pulmonary embolism (SPE) are lacking. The purpose of the present study was to investigate the clinical features of SPE and to ascertain the risk factors for mortality in patients with this condition. Patients with SPE, whose data were retrospectively collected from a tertiary referral center in Korea, were categorized by the presence or absence of in-hospital death into two groups: death and survival groups. The two groups were compared for clinical and radiologic parameters. SPE was community-acquired in most patients (78%). The most common focus of primary infection was that of bone, joint, or soft tissue (33%), followed by liver abscess (17%). The in-hospital mortality was 12%. Multivariate analysis showed that tachypnea (odds ratio [OR] 4.73, 95% confidence interval [CI] 1.09-20.53, p = 0.038) and segmental or lobar consolidation on computed tomography (CT) scan (OR 10.79, 95% CI 2.51-46.43, p = 0.001) were independent predictors of in-hospital death in SPE patients. Taken together, the primary infectious foci of SPE in Korea are different from those reported in Western countries. Tachypnea and segmental or lobar consolidation on CT scan may be independent risk factors for in-hospital death in these patients.

OBJECTIVE: The aim of this study was to compare the effectiveness of percutaneous needle aspiration (PNA) and percutaneous catheter drainage (PCD) in the management of liver abscess. METHODS: Electronic searches (Cochrane Library, MEDLINE, EMBASE, SCIE) were conducted to identify randomized controlled trials (RCTs) comparing PNA and PCD. A meta-analysis was subsequently performed. RESULTS: A total of five RCTs covering 306 patients were included. The meta-analysis showed that outcomes in patients treated with PCD were superior to those in patients treated with PNA in terms of success rate [relative risk (RR): 0.81, 95% confidence interval (CI) 0.66-0.99; P = 0.04], clinical improvement [standardized mean difference (SMD): -0.73, 95% CI 0.36-1.11; P = 0.0001] and days to achieve a 50% reduction in abscess cavity size (SMD: -1.08, 95% CI 0.64-1.53; P < 0.00001). No significant differences were found in duration of hospitalization (mean difference: -0.17, 95% CI -2.10 to 1.75; P = 0.86) or procedure-related complications (RR: 0.50, 95% CI 0.10-2.63; P = 0.41). Days to achieve the total or near total resolution of the abscess cavity and mortality were not calculated because data in the RCTs in the meta-analysis were insufficient. CONCLUSIONS: Both PNA and PCD are safe methods of draining liver abscesses. However, PCD is more effective than PNA because it facilitates a higher success rate, reduces the time required to achieve clinical relief and supports a 50% reduction in abscess cavity size. However, among successfully treated patients, the outcomes of PNA are comparable with those of PCD.

BACKGROUND: Recently, a striking new clinical manifestation of Klebsiella pneumoniae (KP) infection referred to as invasive KP liver abscess syndrome (IKPLAS), defined by liver abscess with contemporaneous metastatic KP infections at other body sites has been documented. Until now, however, there have been relatively few reports regarding its radiologic features. PURPOSE: To describe the clinical and radiological features of IKPLAS patients, and to compare them with those with KP liver abscess without metastatic infections to ascertain possible predictors of IKPLAS. MATERIAL AND METHODS: From January 2008 to May 2010, 35 patients (26 men and 9 women; mean age, 59.4 years) with both liver abscess and metastatic KP infections were diagnosed with IKPLAS. Their clinical and radiological features were retrospectively evaluated and compared with those of 25 contemporaneous non-metastatic patients to investigate predictive factors for metastatic infections. RESULTS: The rate of intensive care unit admissions and overall mortality was 34.3% and 17.1% in IKPLAS patients, and was significantly higher than those of the non-metastatic group (8% and 0%, respectively). As for metastatic infections, the lung was the most common site and multiple nodules or masses (n = 9) were the most common manifestations. Univariate analysis revealed that liver abscess ≤5.8 cm, bilobar involvement of abscess and altered mentality were significantly related with IKPLAS. At multivariate analysis, liver abscess ≤5.8 cm was proven to be a significant independent predictor of IKPLAS (OR, 3.6; P = 0.038). In addition, altered mentality was present solely in IKPLAS (25.7% vs. 0%) although its P value (P = 0.052) did not reach a statistical significance at multivariate analysis. CONCLUSION: IKPLAS has significantly worse prognosis than non-metastatic KP abscess patients. In patients with KP liver abscess, liver abscess ≤5.8 cm can be used as an independent predictor of IKPLAS and altered mentality as a very specific feature in diagnosing IKPLAS.

The genetic mechanisms that contribute to reduced susceptibility to vancomycin in Staphylococcus aureus are complex and heterogeneous. In addition, debate is emerging as to the true effect of reduced susceptibility to vancomycin on staphylococcal virulence. To investigate this, comparative genomics was performed on a collection of vancomycin-exposed isogenic S. aureus pairs (14 strains in total). Previously described mutations were observed in genes such as vraG, agrA, yvqF, and rpoB; however, a new mechanism was identified involving a serine/threonine phosphatase, Stp1. After constructing an stp1 deletion mutant, we showed that stp1 is important in vancomycin susceptibility and cell wall biosynthesis. Gene expression studies showed that stp1 also regulates virulence genes, including a hemolysin, superantigen-like protein, and phenol-soluble modulin, and that the deletion mutant is attenuated in virulence in vivo. Stp1 provides a new link between vancomycin susceptibility and virulence in S. aureus.

Severe infections caused by hypermucoviscous Klebsiella pneumoniae have been reported in Southeast Asian countries over the past several decades. This report shows their emergence in France, with 12 cases observed during a 2-year period in two university hospitals. Two clones (sequence type 86 [ST86] and ST380) of serotype K2 caused five rapidly fatal bacteremia cases, three of which were associated with pneumonia, whereas seven liver abscess cases were caused by K1 strains of ST23.

PURPOSE: To assess retrospectively the cause of hepatic failure related to hepatic arterial embolization (HAE) for hemostasis after pancreaticoduodenectomy or hepatic lobectomy. MATERIALS AND METHODS: Between June 1993 and March 2006, Twenty HAEs in 17 patients (15 men, two women; mean age, 64 years) were performed. Angiographic findings, including portal vein stenosis, collateral arterial pathways after HAE, and the difference of embolic materials, were recorded. The morbidity (hepatic failure and abscess) and mortality were detailed according to collateral arterial pathways, portal vein stenosis, and embolic material used. RESULTS: Bleeding was controlled in all patients, although two patients required repeat embolization. Hepatic failure (n = 8) and abscess (n = 2) arose in nine of 20 HAEs. Death occurred after six of eight HAEs complicated by hepatic failure. The morbidity and mortality rates of HAE were 45% and 30%, respectively. Hepatic complication was eight times more likely to occur (P = .005) in cases with no hepatic collaterals involving hepatic, replaced, or accessory hepatic arteries. Death was observed only in the cases without hepatic collaterals (P = .011). The correlation between the embolization outcome and the presence of portal vein stenosis or the difference of embolic materials was not significant (P > .61). CONCLUSIONS: HAE can be used to successfully control bleeding secondary to hepatic arterial rupture. In the absence of hepatic collaterals, collateral circulation distal to the occlusion from nonhepatic sources may be inadequate and lead to hepatic failure after HAE.

INTRODUCCIÓN: El absceso hepático (AH) es el tipo mas común de abscesos viscerales. Se estima que el perfil epidemiológico de esta enfermedad ha cambiado con el aumento de la resistencia de los microorganismos y el uso de nuevos medicamentos. OBJETIVO: Describir las características demográficas y clínicas de los pacientes hospitalizados con diagnóstico de AH en un hospital universitario del suroccidente colombiano. MÉTODOS: Se realizó un estudio observacional retrospectivo, en la Fundación Valle del Lili, Cali, Colombia. Se incluyeron pacientes mayores de 18 años con diagnóstico de AH hospitalizados entre 2011-2020. RESULTADOS: Se incluyeron 182 pacientes. La mediana de edad fUe 56 años (rango intercuartílico, 45-67) y 62,1% fueron hombres. El microrganismo mas común fue Klebsiella pneumoniae (17,6%). La mayoría requirió drenaje percutáneo (58,2%). El 58,8% tuvo un absceso único y 54,4% fue manejado en cuidados intensivos. El 7,1% de los pacientes falleció. Al comparar los casos que fueron manejados en cuidados intensivos vs. aquellos que no lo fueron, hubo más hepatomegalia (28,3 vs. 11,0%, p = 0,004), derrame pleural derecho (48,5 vs. 28,1%, p = 0,010), cirugía (42,4 vs. 13,4%, p < 0,001), falla terapéutica (22,2 vs. 7,3%, p = 0,007) y muerte (12,1 vs. 1,2%, p = 0,005) en los atendidos en UCI. CONCLUSIÓN: Las Enterobacterales son la principal causa de AH en nuestra población. La mortalidad ha disminuido, pero la hospitalización en cuidados intensivos sigue siendo alta.
BACKGROUND: Liver abscess (LA) is the most common type of visceral abscess. It is estimated that the epidemiological profile of this disease has changed with the increase in resistance and the use of new drugs. AIM: To describe the demographic and clinical characteristics of hospitalized patients with a diagnosis of LA in a university hospital in the southwestern region of Colombia. METHODS: A. retrospective observational study was conducted at Fundación Valle del Lili, Cali, Colombia. Patients older than 18 years with a diagnosis of LA hospitalized between 2011-2020 were included. RESULTS: A total of 182 patients were included. The median age was 56 years (interquartile range, 45-67) and 62.1% were men. The most common microorganism was Klebsiella pneumoniae (17.6%). The majority required percutaneous drainage (58.2%). A 58.8% had a single abscess and 54.4% were treated in ICU. A 7.1% of the patients died. When comparing cases treated in the ICU vs. those who did not, there was more hepatomegaly (28.3 vs. 11.0%, p = 0.004), right pleural effusion (48.5 vs. 28.1%, p = 0.010), surgery (42.4 vs. 13.4%, p < 0.001), therapeutic failure (22.2 vs. 7.3%, p = 0.007) and death (12.1 vs. 1.2%, p = 0.005) in patients treated in ICU. CONCLUSION: Enterobacterales are the main cause of LA in our population. Mortality has decreased, but intensive care hospitalization remains high.

BACKGROUND: Primary liver abscess caused by Klebsiella pneumoniae is an infection that is emerging worldwide and that is associated with severe morbidity and considerable mortality. METHODS: A retrospective analysis of 110 episodes of primary liver abscess caused by K. pneumoniae that required hospitalization during 2001-2002 was conducted to identify predictors of metastatic infection, mortality, and the efficacy of first-generation cephalosporins and percutaneous drainage. The potential role of Klebsiella rmpA and magA genes was also evaluated. RESULTS: The study included 59 men and 51 women, with a mean age of 61.8 years. Diabetes was noted in 67 patients (60.9%). Metastatic infection occurred in 17 patients (15.5%), with meningitis accounting for 11 patients (64.7%) and endophthalmitis accounting for 4 patients (23.5%). The overall mortality rate was 10.0% (11 patients). Most of the severe complications occurred within the first 3 days after hospital admission. Ninety-two patients (83.6%) received treatment with cefazolin for >3 days. Four patients (4.3%) of the group who received cefazolin had metastatic infection, 1 patient (1.1%) experienced septic shock, and 3 (3.3%) experienced acute respiratory failure. Five (5.4%) of those 92 patients died. Multivariable analysis revealed that rmpA (odds ratio [OR], 28.85), Acute Physiologic and Chronic Health Evaluation (APACHE) II score >or=20 (OR, 8.08), and septic shock (OR, 4.33) were statistically significant predictors of metastatic infection. Metastatic infection (OR, 6.73), severity of disease (APACHE II score >or=16; OR, 11.82), septic shock (OR, 8.30), acute respiratory failure (OR, 69.92), and gas formation revealed on imaging (OR, 13.26) predicted mortality. Pigtail drainage protected against both metastatic infection (OR, 0.25) and mortality (OR, 0.14). CONCLUSION: Management of primary liver abscess caused by K. pneumoniae with use of first-generation cephalosporins and percutaneous drainage was associated with low rates of mortality, metastatic infection, and complications. These rates are comparable to those reported for third-generation cephalosporins.

PURPOSE: Hypervirulent Klebsiella pneumoniae (hvKp) has emerged as a leading cause of severe community-acquired pneumonia, liver abscess and disseminated infection in the Far East. Data regarding the incidence, clinical features and microbiological characteristics related to hvKp infections in the Western world are scarce. METHODOLOGY: The incidence, clinical features and microbiological characteristics of hvKp infections were investigated through a 5-year survey conducted in a single French intensive care unit. K. pneumoniae strains were screened for hypermucoviscosity based on a string test. Multilocus sequence typing and multiplex PCR analysis targeting virulence genes were performed on string test-positive strains. RESULTS: Over a 53-month period, a total of 59 infections due to K. pneumoniae were identified including 26 community-onset infections. Twelve hvKp infections were documented, accounting for 46.1â% of community-acquired K. pneumoniae. Community-acquired pneumonia (n=6), aspiration pneumonia (n=4) and liver abscess (n=2) represented initial sites and mode of infection. Compared to non-hvKp infections, patients with hvKp infections displayed higher rates of multi-organ failure (83.3â% vs 35.7â%; P=0.04), but mortality rates were not different (50â% vs 35â%; P=0.71). Strains K1/ST23 (n=5) and K2/ST86 (n=5) predominated. All hvKp strains displayed wild-type susceptibility. CONCLUSION: hvKp represent a potentially underestimated cause of fatal infections in the Western world.

In Thailand, the burden of liver abscess, a life-threatening infectious disease, has not been thoroughly evaluated. We developed a predictive scoring system to estimate survival of patients with liver abscess using information from the 2008-2013 Nationwide Hospital Admission Data to evaluate the burden of liver abscess in Thailand. All patients with primary diagnosis of pyogenic liver abscess (PLA) and amoebic liver abscess (ALA) were included. Epidemiological data, baseline characteristics, hospital course, and survival were analyzed. Overall, 11,296 admissions comprising 8,423 patients from 844 hospitals across Thailand were eligible for analysis. The mean age was 52 ± 17 years and 66.1% of patients were male. ALA was significantly prevalent in southern and western border regions of Thailand, and PLA occurred nationwide. The highest incidence of liver abscess occurred in the rainy season (June-November, P < 0.01). The median length of hospital stay was 8 days (interquartile range = 4-13 days), and mean direct cost of hospitalization was 846 ± 1,574 USD. The overall inhospital mortality rate was 2.8%. Incidence of ALA decreased over the 5-year study period, whereas PLA incidence increased (P < 0.01). Using multivariable Cox regression methods with stepwise variable selection, we developed a final model with five highly significant baseline parameters associated with increased 60-day mortality: older age, PLA, underlying chronic kidney disease, cirrhosis, and human immunodeficiency virus infection. Range of estimated probability of 60-day survival was 95-16% at cumulative risk score 0-13. This simplified score is practical, and may help clinicians prioritize patients requiring more intensive care.

Introducción: La extensión transdiafragmática del absceso hepático piógeno constituye un caso raro de empiema pleural. Es una enfermedad de progresión rápida y con altas tasas de mortalidad, cercanas al 100 por ciento si no se trata a tiempo. Objetivo: Describir el caso de una paciente con empiema pleural derecho, secundario a ruptura de absceso piógeno del lóbulo hepático izquierdo. Caso clínico: Paciente femenina de 70 años de edad que acude al cuerpo de guardia con fiebre, dolor abdominal, síndrome general. La tomografía computadorizada mostró absceso hepático el lóbulo izquierdo con licuefacción casi total y posteriormente presentó como complicación un empiema torácico derecho. La paciente fue tratada con drenaje con sonda pleural. A pesar de los tratamientos antibióticos y quirúrgicos oportunos la paciente fallece en shock séptico. Conclusiones: Se reporta un caso raro de empiema secundario a absceso hepático del lóbulo izquierdo. La demora de la paciente en acudir a instituciones de salud conllevó al fallecimiento de la paciente a pesar del tratamiento antibiótico y quirúrgico(AU)
Introduction: The transdiaphragmatic extension of the pyogenic liver abscess constitutes a rare case of pleural empyema. It is a rapidly progressive disease with high mortality rates close to 100 percent if it is not treated in time. Objective: To describe the case of a patient with right pleural empyema secondary to a ruptured pyogenic abscess of the left hepatic lobe. Clinical case: A 70-year-old female patient who came to emergency with fever, abdominal pain and general syndrome. The computed tomography scan showed a liver abscess in the left lobe with almost total liquefaction, and later a right thoracic empyema was a complication. The patient was treated with chest tube drainage. Despite timely antibiotic and surgical treatments, the patient died of septic shock. Conclusions: A rare case of empyema secondary to liver abscess of the left lobe is reported. The delay of the patient in going to health institutions led to the death of the patient despite antibiotic and surgical treatment(AU)

OBJECTIVES:: Septic pulmonary embolism is an uncommon but life-threatening disorder. However, data on patients with septic pulmonary embolism who require critical care have not been well reported. This study elucidated the clinicoradiological spectrum, causative pathogens and outcomes of septic pulmonary embolism in patients requiring critical care. METHODS:: The electronic medical records of 20 patients with septic pulmonary embolism who required intensive care unit admission between January 2005 and December 2013 were reviewed. RESULTS:: Multiple organ dysfunction syndrome developed in 85% of the patients, and acute respiratory failure was the most common organ failure (75%). The most common computed tomographic findings included a feeding vessel sign (90%), peripheral nodules without cavities (80%) or with cavities (65%), and peripheral wedge-shaped opacities (75%). The most common primary source of infection was liver abscess (40%), followed by pneumonia (25%). The two most frequent causative pathogens were Klebsiella pneumoniae (50%) and Staphylococcus aureus (35%). Compared with survivors, nonsurvivors had significantly higher serum creatinine, arterial partial pressure of carbon dioxide, and Acute Physiology and Chronic Health Evaluation II and Sequential Organ Failure Assessment scores, and they were significantly more likely to have acute kidney injury, disseminated intravascular coagulation and lung abscesses. The in-hospital mortality rate was 30%. Pneumonia was the most common cause of death, followed by liver abscess. CONCLUSIONS:: Patients with septic pulmonary embolism who require critical care, especially those with pneumonia and liver abscess, are associated with high mortality. Early diagnosis, appropriate antibiotic therapy, surgical intervention and respiratory support are essential.

The presenting features, modes of treatment and clinical course were reviewed for 55 patients with pyogenic liver abscess, seen at Duke University Medical Center over a 15-year period. Thirty-three patients had a solitary abscess and 22 had multiple abscesses. Most patients were between the ages of 40 and 60 years. Males predominated, 2.4:1. Major underlying conditions included biliary tract disease, malignancy and colonic disease. Eight patients, each with a solitary abscess, had no identifiable underlying condition. Symptoms and signs were nonspecific: fever, chills, focal abdominal tenderness and hepatomegaly were common. A raised serum alkaline phosphatase level was the most consistent abnormal laboratory finding. CT with contrast enhancement, radioisotope scanning and ultrasonography all accurately defined solitary hepatic abscesses. However, CT scan was more successful than other imaging techniques in detecting multiple abscesses. In seven patients the diagnosis was made only at laparotomy. Overall, a diagnosis of liver abscess was made in 50 living patients (91%). Microorganisms were recovered from pus and/or blood cultures of 44 patients (80%). Most common were enteric gram-negative facultative rods, anaerobic gram-negative rods, and microaerophilic streptococci. Single abscesses were more likely than multiple abscesses to contain more than one organism. All patients received antibiotics; the choice of antibiotic does not appear to be critical provided the regimen has a broad spectrum including activity against anaerobes. Surgical or percutaneous drainage was successful when attempted in all patients with a single abscess, but the outcome was less favorable in those with multiple abscesses. Percutaneous drainage is currently replacing open operative drainage as the method of choice. Overall mortality in patients with single abscesses was 15% (5/33) and in those with multiple abscesses 41% (9/22).

Pyogenic liver abscess (PLA) is an important entity with a changing clinical spectrum and may be more prevalent than previously reported. PLA remains most common in older patients, although we found a trend in age range downward. In contrast to earlier reports, PLA affected male and female patients with equal frequency. The most common known cause of PLA remains biliary tract disease, but the majority of patients with PLA were those in whom no underlying cause of PLA could be identified. Single PLA was more common than multiple PLA regardless of etiology. The clinical presentation of patients with PLA ia nonspecific and emphasizes the fact that a high index of suspicion is often required to make the diagnosis. Jaundice and a markedly elevated alkaline phosphatase are clues to the possibility of biliary tract involvement, but may not distinguish patients with liver abscess from those with other hepatic processes. While plain chest and abdominal X-rays were often abnormal and may point to the right upper quadrant as a source of abnormality, ultrasound (US) and abdominal computed tomography (CT) play a central role in this disease. Not only are they often paramount in elucidating the diagnosis of PLA, but US and CT are critical because of their ability to provide other useful information that may address the cause of PLA (that is the biliary tract, and in the case of abdominal CT, other structures). Further, our data suggest that in patients without clinical or imaging evidence of biliary tract disease or pylephlebitis, aggressive random evaluation of the intestinal tract is unwarranted. Percutaneous drainage combined with intravenous antibiotics was the most common therapeutic modality and resulted in cure in 76% of all patients in which it was used (compared to 65% with antibiotics alone and 61% with surgery) and has been successful in 90% of patients over the last 5 years (n = 50). In this study, percutaneous catheter drainage (PCD) appeared to result in a higher cure rate than percutaneous needle aspiration (PNA) but comparative studies are required to further address and determine their relative efficacies. Intravenous antibiotics alone are an important option in carefully selected patients. Surgical intervention as a primary mode of therapy has been almost completely replaced by less invasive approaches such as PCD/PNA, but remains an important consideration in patients who fail these therapies. Although PLA was once considered a fatal disease, the prognosis is now excellent. We have identified a subgroup of patients with no or low-level elevations in bilirubin and alkaline phosphatase and most often single right-sided PLA who do not have a readily identifiable cause of PLA (that is, cryptogenic), as having a particularly favorable prognosis. Death due to PLA is now limited primarily to those patients with severe underlying disease processes, including malignancy.

The cause of liver abscess is frequently obscure at initial presentation. We reviewed the medical records of 20 patients with pyogenic liver abscess over a 6-year period from 1981 to 1987. Liver abscess was suspected in only 3 patients on admission; the most common initial diagnosis was fever of unknown origin. Subsequently, the origin of the abscess was found to be intestinal in 7 patients, pancreatobiliary in 11 patients, and cryptogenic in 2 patients. Eleven patients underwent percutaneous transhepatic drainage of the abscess as the initial treatment, while open operation was the initial treatment in 9 patients. Percutaneous transhepatic drainage was ultimately successful in only 4 patients (36%). In the absence of an obvious pathologic condition of the biliary tract, all patients should undergo full gastrointestinal evaluation.

BACKGROUND: Prognosis of pyogenic liver abscesses in patients with malignant disease is generally considered poor. The discrepancy between the outcomes of liver abscesses caused by hepatopancreatobiliary malignant disease and those caused by other malignant diseases, however, to our knowledge has never been investigated. OBJECTIVES: To clarify the clinical course of pyogenic liver abscess in patients with different types of cancer, and to compare outcomes in abscesses caused by hepatopancreatobiliary malignant disease and other malignant disease. DESIGN: Retrospective review of case series in our experience from 1980 through 1993. SETTING: Tertiary care university teaching hospital. PATIENTS: Fifty-two patients with pyogenic liver abscess related to the underlying cancer were divided into 2 groups. Group 1 (n=32) was composed of patients with cancer originating from the hepatic parenchyma, bile duct, and pancreas; group 2 (n=20) was composed of patients with cancer originating from other sites. INTERVENTIONS: Parenteral antibiotics, percutaneous drainage, surgical drainage, or hepatectomy, in combinations, were employed. MAIN OUTCOME MEASURES: Patient characteristics, symptoms, laboratory data, abscess characteristics, microbiological study, management, and outcome of the 2 groups were analyzed. RESULTS: Thirteen patients (41%) in group 1 and 16 patients (80%) in group 2 had undergone prior anticancer treatment. Jaundice was encountered more often in group 1 than in group 2 (29 patients [91%] vs 6 patients [30%], respectively, P=.001), whereas nausea and vomiting were more frequently seen in group 2 than in group 1 (17 patients [52%] vs 6 patients[31%], respectively, P=.04). Leukocytosis, hypoalbuminemia, hyperbilirubinemia, and reversed albumin-globulin ratio were more pronounced in group 1 than in group 2 (P=.001, .02, .003, and .03, respectively). Abscesses communicating with the intrahepatic biliary tree were more frequently encountered in group 1 than in group 2 (11 patients [34%] vs 2 patients [10%], respectively, P=.03). Escherichia coli and Klebsiella pneumoniae predominated in group 1, while the bacteria species in group 2 were more diverse. The hospital mortality rates of group 1 and group 2 were 28% (9 of 32 patients) vs 10% (2 of 20 patients) (P=.04), respectively. Twenty-three patients (72%) of group 1 died of uncontrolled biliary sepsis or progressive cancer or both within 6 months after the diagnosis, while 17 patients (85%) of group 2 survived longer than 1 year without relapse of the abscess and continued with anticancer treatment. CONCLUSIONS: Pyogenic liver abscess could be a presentation of hepatopancreatobiliary malignant disease at the preterminal stage, and carries a grave prognosis. Pyogenic liver abscess in patients with nonhepatopancreatobiliary malignant disease has a better chance of favorable outcome.

A retrospective review of 39 patients with pyogenic hepatic abscess treated from 1977 through 1984 included 23 patients who were surgically treated and 16 who underwent percutaneous drainage. The average age in each group was similar (about 55 years). The most common cause of abscesses in each group was biliary tract disease. Abscesses caused by portal seeding and local extension were more common in the surgical group, 14 of whom required additional surgical procedures at the time of surgical drainage. Of the 16 patients in the percutaneously drained group, seven were seen during the immediate postoperative period. Most of the abscesses occurred in the right lobe of the liver, but single abscesses in the left lobe (30%) and multiple abscesses (57%) were more common in the surgical group. Klebsiella enterobacter and group D streptococcus were most common in the surgically and percutaneously drained groups, respectively. All patients received antibiotics, with a mean length of treatment of 14 days. Mean time to defervescence was about four days in both groups, with a longer hospital stay for the percutaneously drained group (26 vs 46 days). Morbidity was high in both groups (surgical, 48%; percutaneous, 69%). Three of the percutaneously treated patients required surgical drainage because of highly viscous abscess contents. Mortality was 17% in the surgical group and 13% in the percutaneously drained group. Percutaneous drainage with computed tomography probably should be the initial drainage procedure in patients with pyogenic hepatic abscesses in whom no concomitant surgical procedure is planned. Regardless of treatment, the morbidity and mortality remain high.

PURPOSE: Liver abscess is rare in patients with cirrhosis of the liver. The aim of this retrospective study was to investigate the incidence, clinical presentation, causal pathogens, and outcome of liver abscess in cirrhotic patients. METHODS: We collected 21 liver abscess specimens (from 14 male patients and 7 female patients; Child A: B: C, 4: 7: 10) from 22,731 admissions of 6450 cirrhotic patients, from 1986 through 1998. RESULTS: The common clinical symptoms and signs included fever, chills, and abdominal tenderness. The major predisposing factors were biliary tract disease (52%) and diabetes mellitus (48%). The diagnosis rate with abdominal ultrasonography was 79%. Gram-negative aerobes were the predominant pathogens (Klebsiella pneumoniae, 66.7%; Escherichia coli, 23.8%), and occurred in 80% and 69% of blood and pus cultures, respectively, while 38% of cases showed polymicrobial pathogens. The location of the abscess was predominantly in the right lobe (71.4%), and 47.6% of patients had multiple abscesses. Six patients died (all with Child C cirrhosis). The overall mortality rate was 28.6% (6/21). CONCLUSIONS: The incidence of liver abscess in the cirrhotic patients was low, at 0.09% (21/22,731 admissions). The clinical presentations and pathogens were not different from those in noncirrhotic patients, except that in our cirrhotic patients, there was no significant difference in mortality between those with monomicrobial and those with polymicrobial abscess: nor was there a significant difference in mortality between those with single and those with multiple abscesses. The Child C patients were the high-risk group.

This study demonstrates that hepatic abscesses are highly lethal when untreated. There was an overall mortality of 29 per cent; however, if autopsy cases are excluded the mortality was only 13 per cent. Positive blood cultures (especially if multiple or anaerobic organisms), significant anemia, elevated bilirubin levels, multiple abscesses, and being Caucasian were identified as factors associated with increased mortality. Early diagnosis coupled with aggressive surgical and antibiotic therapy is needed.
