Eikenella corrodens liver abscess complicated by endophthalmitis.

A 64-year-old man who presented with sudden, unilateral loss of vision was found to have endophthalmitis associated with a pyogenic liver abscess. The patient was successfully managed with subtotal vitrectomy and percutaneous drainage of the liver abscess. Eikenella corrodens was cultured from the blood and the pus drained from the liver abscess. This is the first reported case of Eikenella corrodens liver abscess complicated by endophthalmitis.

Computed tomography of experimental liver abscesses using a new liposomal contrast agent.

RATIONALE AND OBJECTIVES: Evaluation of computed tomographic enhancement characteristics of a new liposomal contrast agent (liposomal iodixanol [LI]) in a pyogenic liver abscess model in 17 rabbits. METHODS: Eight to 14 days after abscess induction (Escherichia coli), density-time curves were calculated for regions of interest in liver, abscess wall and center, spleen, portal vein, abdominal aorta, inferior vena cava, and kidney. Images were obtained every minute between 1 and 10 minutes, every 5 minutes between 15 and 60 minutes, and 75 minutes after 200 mg/kg LI application (group A: 7 rabbits) and after 600 mg/kg iopentol application (group B: 10 rabbits), and 90, 105, and 120 minutes after LI. RESULTS: The abscess wall-liver contrast after LI lasted from 10 to more than 120 minutes with a maximum of 30 delta Hounsfield Units (HU) at 45 minutes. For iopentol, the abscess wall-liver contrast lasted from 2 to 7 minutes with a maximum of 8 delta HU at 5 minutes. The abscess wall-center contrast after LI lasted from 1 to more than 120 minutes with a maximum of 112 delta HU at 40 minutes. For iopentol, the abscess wall-center contrast lasted from 1 to 75 minutes with a maximum of 79 delta HU at 1 minute. The liver-portal vein contrast after LI lasted from 1 to more than 120 minutes with a maximum of 100 delta HU at 20 minutes. For iopentol, the liver-portal vein contrast lasted from 1 to 8 minutes with a maximum of 38 delta HU at 2 minutes. An abscess wall was detected in a higher percentage of the LI images (86% LI, 56% iopentol), and images in the LI group correlated better with histopathology. CONCLUSIONS: The diagnostic value of LI exceeds that of iopentol in terms of overall abscess contrast and duration of the diagnostic interval. The higher hepatic vessel contrast allows better abscess localization.

A comparison of amebic and pyogenic abscess of the liver.

We evaluated the clinical features of 96 cases of amebic liver abscess and 48 of pyogenic hepatic abscess. Most patients with amebic abscess were young Hispanic males. Those with pyogenic abscess were older, without any ethnic predominance. Symptoms tended to be acute and localized to the right upper quadrant in amebic infection. In pyogenic disease, symptoms were often nonspecific and chronic in nature. A marked shift to the left of the leukocyte count occurred more frequently in pyogenic abscess, as did markedly abnormal values of the serum albumin, direct bilirubin, lactic dehydrogenase and aspartate aminotransferase. Sonography detected all cases of amebic abscess and missed the lesions in 2 of 39 patients with pyogenic abscess. Abscess cultures yielded pathogens in 90% of cases of pyogenic disease, while blood cultures were positive in 50%. Five of 20 patients with positive blood cultures had additional organisms isolated from the abscess that would have required adjustment of antibiotics for optimal coverage. We believe that all pyogenic abscesses should be aspirated to guide antibiotic therapy. In amebic abscess, the diagnosis was usually based on clinical and sonographic findings, aspiration being performed in only 14% of cases. Ninety-eight percent of patients were treated with amebicidal agents alone, and all responded to therapy. Therapeutic needle aspiration is rarely necessary. In pyogenic abscess, prolonged fever was common during medical therapy. Even in those eventually cured without surgery, the median time to defervescence was 8 days. Though 19 patients underwent surgical drainage, only 2 clearly did not benefit from medical treatment, having high fevers after more than 2 weeks on a regimen of appropriate antibiotics. Surgery is often performed prematurely because physicians expect fever to resolve quickly, but persistent fever of less than 2 weeks' duration should not constitute an indication for surgical drainage. Seven patients with pyogenic abscess died, 5 as a result of hepatic abscess. In 3 of these cases, the diagnosis was unsuspected till autopsy. Improved awareness of this disease may decrease morbidity and mortality from this treatable condition.

Clinical and microbiological features of liver abscess after transarterial embolization for hepatocellular carcinoma.

OBJECTIVES: To present the clinical and microbiological features of liver abscess after transarterial embolization (TAE) for hepatocellular carcinoma (HCC). METHODS: We retrospectively reviewed records of 452 TAE procedures in 289 patients with HCC over a 2-yr period. RESULTS: Four men and one woman with a mean age of 68.4 yr were diagnosed with liver abscess 1-8 wk (mean 4.6 wk) after the embolization. The incidence was 1.1% (5/452). Common symptoms included fever, chills, and right upper quadrant pain. Serum aminotransferase, alkaline phosphatase, and gamma-glutamyltransferase levels and leukocyte count were frequently elevated. All the abscesses appeared as areas of hypodensity on CT scan and hypoechogenicity on ultrasonogram. The areas contained gas in the embolized tumor, which led to the suspicion and finally the diagnosis of abscess. In contrast to predominance of gram-negative aerobes in sporadic pyogenic liver abscesses, the causative microorganism was predominantly gram positive (60%). All patients were treated with parenteral antibiotics plus percutaneous aspiration, drainage, or operation, but one patient died from the abscess. CONCLUSIONS: For patients receiving TAE for HCC, few specific clinical or radiological features could readily differentiate patients complicated with liver abscess from those without. This may delay a timely diagnosis and lead to significant morbidity. Hence, in patients with risk factors, including old age, previous biliary tract disease, large tumor size (>5 cm), and gas forming in the embolized tumor, aspiration of the suspected focal hepatic lesion should be performed as soon as possible.

[Pyogenic hepatic abscess: report of 51 cases].

Pyogenic hepatic abscesses are uncommon. We report our findings in 51 patients with pyogenic liver abscess treated from 1975 through 1992. Twenty-eight patients were men and twenty-three were women. The median age of patients was 46 years (range, 13 to 77 years). Fever was present in 100% of patients, abdominal pain in 58.8% and jaundice in 39.2%. Twenty eight patients (54.9%) had leukocytosis; 45% hyperbilirrubinemia and 35.3% a high serum level of alkaline phosphatase. The most common cause of abscesses was biliary tract disease (66%). Thirty-three (64.7%) were surgically treated and thirteen underwent percutaneous drainage with 90.4% and 69.2% of good results, respectively. Mortality was 9.6% in the surgical group and 0% in the percutaneously drained group. A review of literature of this condition and a discussion about the diagnosis, treatment and etiopathogenesis are presented.

Liver abscesses in children: a single center experience in the developed world.

OBJECTIVES: The aim of this study was to investigate the clinical and radiologic features, predisposing risk factors, and complications of children with pyogenic liver abscess (PLA) referred to a tertiary pediatric hepatology center. METHODS: We analyzed our database of all children referred to our unit over a 10 year period and performed a case note review of all patients with a radiologically proven PLA. RESULTS: PLA was diagnosed in 15 children (7 boys), 0.5% of all referrals. They presented at a median age of 10 years (range 2 months-15 years). In three children (2 boys), PLA was the first manifestation of chronic granulomatous disease. Among the others, five had radiologic evidence of other intra-abdominal pathology (1 with subsequently proven appendicitis), and four developed portal vein thrombosis with portal hypertension. The commonest isolated pathogen was Staphylococcus aureus. Combined treatment with guided aspiration and prolonged intravenous antibiotics was successful in all patients. CONCLUSION: PLA is a rare diagnosis in children in the developed world. It may be caused by primary neutrophil disorders even in the absence of a previous history of infection. Co-existent appendicitis, intra-abdominal sepsis, and ascending pylephlebitis must be sought because these children are at risk of developing portal vein obstruction and portal hypertension. Prolonged intravenous antibiotic treatment guided by microbiologic sensitivities is highly effective.

Epidemiological aspects of liver abscesses in children in the Western Cape Province of South Africa.

A high incidence (28 per 100,000 admissions) of liver abscesses is reported in children from the Western Cape Province of South Africa. Of a total of 84 childhood hepatic abscesses over a 10-year period, 51 per cent (43 patients) were primary pyogenic, 30 per cent (25 patients) amoebic, 2 per cent (two patients) Ascaris, and 17 per cent (14 patients) were culture negative. Protein calorie malnutrition was evident in 56 per cent of cases. Amoebic abscesses originated in patients from rural areas, whereas pyogenic abscesses occurred in patients from urban and periurban environments. Staphylococcus aureus was cultured in 85 per cent of pyogenic liver abscesses. Gram negative organisms were identified in four cases of amoebic hepatic abscess where secondary infection occurred. Co-existing parasites of Ascaris lumbricoides and Trichuris trichiura were identified in the stools of 31 per cent of patients. A low (4.8 per cent) mortality is reported for this series.

[The conservative treatment of hepatic abscesses with echo-guided transcutaneous drainage].

Liver abscesses are a rare disease with 80-100% mortality in untreated cases. The advent of ultrasound in the clinical practice has improved the prognosis. Surgery for this disease has a percentage of complications of 15-52% and a mortality of 12-33%. In a review of the literature about 200 liver abscesses treated with ultrasound-guided percutaneous drainage the complications were 7.5% and the mortality was 3%. The authors report their personal experience about 21 hepatic abscesses in 13 patients. Nineteen abscesses were treated with ultrasound-guided percutaneous drainage and two with antibiotics. Six patients had pyogenic liver abscesses, two amebic and in five patients the cultures were sterile. In 9 cases the location was in the right lobe of the liver, in 3 was in the left lobe. One patient had multiple abscesses. The size of the abscesses ranged from 0.5 to 13 cm. We drained with Seldinger technique or direct procedure with Trocar's needle under ultrasound guidance without serious complications and without mortality. In 6 cases the patients had pain during the procedure and in 3 cases medical therapy was necessary. In one case we had a pleuritis for the puncture of costophrenic space. All the patients treated had a complete resolution of the abscesses. The ultrasound-guided percutaneous drainage is the treatment of choice for liver abscesses. But other reports with more patients are necessary to clarify the indications and the ultrasound criteria of recovery.

Hepatic abscess resulting from asymptomatic diverticulitis of the sigmoid colon.

I have described a case of pyogenic liver abscess secondary to completely asymptomatic diverticulitis. Because extensive diverticulitis may be present with minimal or no clinical symptoms, it should be strongly considered as the cause when dealing with a so-called "cryptogenic" liver abscess, and treatment should be planned accordingly.

Liver abscess secondary to intrahepatic perforation of the gallbladder, presenting as a liver mass.

We present an unusual case of a large pyogenic liver abscess containing multiple stones caused by perforation of a necrotic gallbladder and spread of the infection into the liver. It manifested by weakness, weight loss, and a palpable liver mass, pointing toward a neoplastic process. Workup for metastatic disease was negative, and tumor markers also were negative. Ultrasound and computerized tomography were inconclusive, and the diagnosis was established by laparoscopy. Open drainage and cholecystectomy were performed, with good outcome. In the literature, there have been very few reports of intrahepatic perforation of the gallbladder resulting in formation of hepatic abscess. The presentation, diagnosis, and management of liver abscesses, as well as the complications of acute cholecystitis, are discussed.

[Hepatic abscess. Diagnostic approach and therapeutic orientation].

The paper examines the cases of 7 patients affected by pyogenic liver abscesses who had been brought to the authors' attention over the last 6 years; 2 of whom presented multiple and 5 single abscesses: 4 were located on the right lobe and 1 on the left lobe. The extent of the pathology, its morbidity and mortality necessitate special attention during the diagnostic path in order to discover the origin. CAT and above all ultrasonography have proved to be indispensable tests. The therapeutic approach, which has been compared with previously published data, has eclectically benefited from both antibiotic treatment, used for multiple abscesses, and the insertion of echo-guided drainage, when general conditions do not permit surgical intervention. In the case of liver abscesses whose origin is evident, surgical drainage remains the obligatory choice, whereas, in the authors' opinion, resective surgery is perhaps out of proportion to this type of disease.

[Pyogenic hepatic abscess].

Ten patients, 6 men and 4 women, with a mean age of 53 years, having pyogenic liver abscess, were studied to review the principal features of the clinical and bacteriological diagnosis. In 9 cases the abscess was located in the right hepatic lobe. Bacteriological diagnosis was made in 6 cases: the etiology was nonmicrobian in 3 and two microorganisms were found in the other 3 cases. The isolated pathogens were: Escherichia coli (3 cases), Staphylococcus sp (3 cases), Enterobacter agglomerans (1 case), Citrobacter sp (1 case), Streptococcus sp (1 case). The basic clinical pattern included fever in 9 patients, pain in upper right side of the abdomen in 8, jaundice in 5 and respiratory symptoms in 5. In 2 cases the diagnosis was confirmed by ultrasonography, in 2 by scintigraphy and in 3 both methods were used. Surgical drainage was practiced in 7 patients, with favorable course in 6. Three patients were not operated; 2 died and the third was cured with medical treatment. The importance of the clinical suspicion even with few data is pointed out, specially prolonged fever with painful syndrome in upper right side of the abdomen. The aid of the diagnosis imaging is valuable for verification. The precise bacteriological diagnosis by culture of the material obtained in surgery or by percutaneous drainage of the abscess allows the selection of the most suitable antibiotic therapy.

Streptococcus milleri infection of a hepatopulmonary hydatid cyst.

A case of hepatopulmonary hydatid disease in a Cypriot who presented with pyogenic infection with Streptococcus milleri is described. Although hydatid disease and pyogenic liver abscess are both rare in the UK, an underlying echinococcal pathology should be suspected in any patient from an area endemic for hydatid who presents with a pyogenic hepatic or hepatopulmonary abscess.

Hepatobiliary infections.

Major hepatobiliary infections include cholangitis and liver abscess. Liver abscess is typically either of pyogenic or amebic origin. Amebic liver abscess usually occurs in individuals from endemic areas or those traveling to endemic areas and is associated with an excellent prognosis if properly managed, usually with one of several antiamebicidal drugs alone. Pyogenic liver abscess is most often cryptogenic in origin, although sophisticated advanced interventional procedures such as transarterial embolization and cryoablation are leading to a new generation of patients with pyogenic liver abscess. A distinct clinical entity appears to be evolving, namely that of monomicrobial Klebsiella pneumoniae pyogenic liver abscess, characterized by the same symptoms and signs as classic pyogenic liver abscess, but further distinguished by the presence of diabetes mellitus, a paucity of coexistent intra-abdominal pathology, a single cavity, and an excellent prognosis. As of 1999, the vast majority of pyogenic liver abscesses should be approached therapeutically by percutaneous aspiration or drainage techniques. The overall prognosis for patients with pyogenic liver abscess is improving, although poor outcomes are common in patients with serious underlying medical disorders, especially malignancy.

Low mechanical index contrast-enhanced sonographic findings of pyogenic hepatic abscesses.

OBJECTIVE: Low mechanical index contrast-specific sonography is a new technique that uses the harmonic capabilities of second-generation contrast agents to produce real-time contrast-enhanced gray-scale images. We describe the contrast-specific sonographic findings of pyogenic hepatic abscesses. CONCLUSION: Contrast-specific sonography was used to assess eight cases of aspiration-confirmed pyogenic liver abscesses. All cases were correlated with multiphasic helical CT findings. Continuous sonographic exploration allowed recognition of morphologic details not detectable on CT images. Contrast-specific sonograms showed features including rim enhancement, arteries along abscess margins and internal septa, dense and persistent septal enhancement, absent microcirculation in fluid and necrotic components, transient arterial phase hypervascularity around abscesses, and portal phase hypovascularity around abscesses. This constellation of findings is suggestive of liver abscess.

[Results of the treatment of pyogenic hepatic abscess over a 10-year period].

The experience of the Hospital Clínico de la Universidad de Chile in the treatment of pyogenic liver abscess, during various periods of the last decade is presented. Fifty six cases treated by means of three therapeutic options are reviewed retrospectively. The overall mortality during period was of 27% and it decreased to 19% if only the last three years were taken into account. There were no significant changes comparing surgical treatment in different periods. Fourteen patients were managed with percutaneous drainage, with therapeutic success in 85% of cases and one death. Five cases were treated only with antibiotics; results were good in four of them. The different mortality figures were analyzed concluding that they belonged to man comparable universes because of the unavoidable patient selection. Surgery was reserved for the more severe cases. Percutaneous drainage is the first choice treatment in patient with solitary abscess without a surgically treatable abdominal primary location.
