Solitary pyogenic liver abscess: a statistical analysis of 117 cases.

In this study, we present 117 cases of solitary pyogenic liver abscess. The average age was 30, and the most important clinical findings were pain (81.8%), chills and fever (52.2%) and hepatomegaly (64.1%). The laboratory findings were as follows: leukocytosis (61.4%), elevated sedimentation rate (71.6%), BUN over 50 mgs (15.3%), average SGOT: 20.1, SGPT: 20.3, and alkaline phosphatase: 82.6 mU. X-ray examination revealed pathological findings in the right pleural cavity and diaphragm in 61.5% of cases. Radioisotope scanning of the liver was helpful in 88.5% of cases. The preoperative diagnosis was correct in 72%. The abscess was located in the right lobe in 83.8%, in the left lobe in 14.5%, and in both lobes in 1.7%. The average abscess volume was 500 cc, and the pus was sterile in 77.7%. The overall complication rate was 31.6%, and the mortality rate was 17.9%. The patients were treated by early systematic surgical drainage.

Pyogenic liver abscesses secondary to carcinoma of the sigmoid colon: a case report and clinical features of 20 cases in Japan.

We report a case of liver abscesses associated with sigmoid colon cancer in an 81-year-old woman. The patient was referred to our hospital because of a tumorous lesion of the sigmoid colon. Five days before the scheduled operation, she presented abdominal pain, fever and chill. Imaging scans revealed multiple liver abscesses in both lobes, which were successfully treated with intravenously administered antibiotics. Two weeks later, the patient underwent laparoscopic-assisted sigmoidectomy. Nineteen cases of liver abscess associated with colonic cancer have been reported during the past ten years in Japan, and we report the clinical features of these cases in this paper. An aggressive search for the underlying cause of pyogenic liver abscess should be an integral part of the definitive treatment of this disease.

Pyogenic liver abscess: warning indicator of silent colonic cancer. Report of a case and review of the literature.

PURPOSE: Carcinoma of the colon, manifested clinically as an enterococcal hepatic abscess, in the absence of liver metastases, is very uncommon. However, having treated a patient with such a condition, we would like to draw the attention of surgeons to this possibility. Most reports describe secondary infections of hepatic metastases only in patients with a known malignancy. However, increased awareness of colonic cancer as an underlying cause of pyogenic liver abscesses will afford earlier diagnosis and treatment. METHODS: The case was analyzed for history, presentation, laboratory data, radiologic studies, and bacteriology. RESULTS: A 66-year-old woman presented with abdominal pain, fever, and chills. Imaging scans revealed a solitary liver abscess, which was successfully treated with percutaneous drainage and broad-spectrum intravenous antibiotics. Pus cultures grew Streptococcus faecalis. A search for the underlying cause led to the discovery of an adenocarcinoma of the sigmoid colon. CONCLUSIONS: An aggressive search for the underlying cause of pyogenic liver abscesses should be an integral part of the definitive treatment of this disease. After prevailing etiologies have been excluded, silent colonic cancer should be considered.

Pyogenic liver abscess: the role of surgical treatment.

MATERIALS AND METHODS: We present an analysis of 48 patients with pyogenic liver abscess (PLA) that were treated according to a protocol between 1975 and 1993. In this period, 35 patients with PLA were treated by surgical drainage (SD). The indication for surgical treatment of the abscess were patients in septic conditions, underlying intra-abdominal surgical disease and the failure/contraindication of other therapeutic methods. Thirty-one patients were submitted to surgical treatment as the initial procedure and four patients unsuccessfully treated by percutaneous drainage, underwent SD. RESULTS: The surgical approach was indicated in patients with severe disease and presented 91.5% of good results, and a mortality rate of 8.5%. CONCLUSIONS: These results suggest that surgical treatment is a good alternative as a first step not only for the treatment of the primary cause of the abscess but also in septic patients with severe disease where a delay in adequate drainage, frequent in percutaneous management, can lead to high morbidity and mortality rates.

Metallic cough and pyogenic liver abscess.

The curious symptom of a metallic cough in association with a pyogenic hepatic abscess should heighten awareness of a fistula. We describe a 78-year-old female with severe diverticular disease, on long-term steroid treatment for polymyalgia rheumatica. She developed a pyogenic liver abscess, treated initially by antimicrobial therapy, and subsequently drained by ultrasound and computed tomography-guided percutaneous transhepatic pigtail catheterization. This was complicated by a fistulous communication between the abscess cavity and the bronchus, confirmed by radiology. After repeated attempts at drainage and antimicrobial therapy the abscess cavity, including the hepatobronchial fistula, resolved.

Continuing changing patterns of disease in pyogenic liver abscess: a study of 38 patients.

Changes in the etiology, clinical features, methods of diagnosis, and treatment of pyogenic liver abscess have occurred slowly but continuously over the past century. The earlier changes are well documented in the literature, and continuing variations in the classic patterns of disease are now evident. These include 1) a recent increase in incidence reflecting more accurate diagnostic techniques; 2) changes in bacteriology with a high incidence of Klebsiella infection; 3) a reduction in mortality, reflecting earlier diagnosis and more refined therapeutic methods; and 4) changes in the population at risk namely a large population of terminal cancer patients. Thirty-eight patients treated at the Mount Sinai Hospital over the past 16 years, 1967-1982, have been divided into two groups, each of 8 years duration, reflecting an earlier era before routine use of scanning procedures, and a later period when technetium, gallium, sonographic, and more recently CT imaging procedures were regularly done. During the latter period there was a significant increase in both the total number of liver abscesses diagnosed and in the number estimated as a proportion of all hospital admissions. Mortality has continued to fall to more acceptable levels with a 25% reduction overall. In the early era, extrahepatic intra-abdominal infection caused all four deaths. In the past 8 years obstructing or metastatic cancer has caused four of the five deaths. Bacteremia occurred in six of the nine deaths, five of these being of biliary origin. The decrease in mortality may reflect earlier diagnosis, an increase in the number of solitary abscesses, and better therapy.

Changing management of pyogenic liver abscess.

The case records of 23 patients who presented over a 5-year period with a diagnosis of pyogenic liver abscess were reviewed. Ascending cholangitis was implicated in nine cases, seven of which were associated with underlying malignancy. Haematogenous spread via the portal route accounted for five cases. Primary treatment included percutaneous abscess drainage in 15 patients. Whereas nine of the 11 patients with benign underlying pathology were managed successfully, the four with malignant biliary obstruction did not survive. Only one of the 23 patients who presented with hepatic abscess required surgical intervention. Percutaneous abscess drainage combined with appropriate antibiotic therapy is an effective means of managing hepatic abscess, but there remains a substantial overall mortality rate resulting from the increasing incidence of malignant biliary obstruction as a cause of this condition.

A member of the delta subgroup of proteobacteria from a pyogenic liver abscess is a typical sulfate reducer of the genus Desulfovibrio.

Strain FH26001/95 (ATCC 700045) was previously isolated from a pyogenic liver abscess from a human. Comparative 16S rRNA gene sequence analysis showed that this strain is related to members of the delta subgroup of the proteobacteria, within a cluster of sulfate-reducing bacteria (Desulfovibrio spp.) and non-sulfate-reducing bacteria (Bilophila wadsworthia and Lawsonia spp.). The phenotype of strain FH26001/95 was found to be typical of members of the genus Desulfovibrio. Growth and substrate transformations were possible at oxygen concentrations of 2 to 5% (vol/vol) but not at oxygen concentrations of 21% (vol/vol) in air. Its isolation from an infection in a human suggests that some members of the genus Desulfovibrio can be considered opportunistic pathogens.

Hepatocellular carcinoma presenting as pyogenic liver abscess: characteristics, diagnosis, and management.

We performed a 17-year retrospective analysis of 10 cases of hepatocellular carcinoma presenting as pyogenic liver abscess. Spontaneous tumor necrosis and biliary obstruction caused by tumor thrombi, superimposed with bacterial infection, were the two major pathogeneses. Exact diagnosis of the underlying hepatocellular carcinoma was made for five of the 10 patients before management was attempted. Main clinical manifestations included fever, chills, right-upper-quadrant pain, malaise, anorexia, jaundice, and hepatomegaly. Characteristics such as middle age and male sex, seropositivity for hepatitis B and/or hepatitis C, chronic liver disease, unexplained anemia, marked weight loss, and a severely inversed albumin/globulin ratio raise suspicions about the underlying hepatocellular carcinoma. Management strategies included percutaneous drainage (n = 3), surgical drainage (n = 4), and hepatectomy (n = 3) in addition to administration of parenteral antibiotics in all cases. The prognosis was dismal, with a mean survival of 3.5 months (range, 8 days to 6 months).

[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. A case report with a short review of current concepts of diagnosis and management.

A case of a large pyogenic liver abscess in a 16-year-old boy with appendicitis is presented. The clinical picture, bacteriology and treatment of the disease are discussed on the basis of 397 cases reported in the literature. It is concluded that ultrasound scanning of the liver is essential for early diagnosis and that the treatment of choice is percutaneous needle aspiration in combination with bactericidal antibiotics.

Pyogenic liver abscess presenting as a "warm" lesion in Ga-67 scintigram. A potential pitfall in interpretation.

In the Ga-67 scintigram, most pyogenic liver abscesses appear to be areas of high radiotracer concentration; rarely photon-deficient lesions may also occur. We present a 58-year-old man with sepsis and hepatic abscess, demonstrated by a Tc-99m BIDA study and a computerized tomogram of the body, showing homogenous radiogallium uptake throughout the liver in the Ga-67 images. To avoid missing such a "warm" lesion, it is emphasized that abdominal Ga-67 scintigrams for localization of a focal inflammatory lesion should be done along with Tc-99m sulfur colloid or Tc-99m BIDA scintigraphy.

Sonographic features of amebic and pyogenic liver abscesses: a blinded comparison.

We blindly compared the sonographic findings in amebic (112 lesions) and pyogenic (30 lesions) liver abscesses. Two sonographic features were significantly more prevalent in amebic abscesses: the lesions had a round or oval shape and the lesions had an echogenicity that was lower than that of normal liver and were internally homogeneous on high-gain scans. Amebic abscesses were round or oval in 92 instances (82%), while 18 pyogenic abscesses (60%) (p less than .01) had these shapes. Fifty-nine (58%) of 101 amebic abscesses displayed low echogenicity and homogeneous internal echoes with high-gain settings compared with nine (36%) of 25 pyogenic abscesses (p less than .04). Despite these different sonographic patterns, image findings alone were inadequate in distinguishing pyogenic from amebic liver abscesses. However, when the sonographic findings were coupled with clinical and laboratory data, a correct diagnosis was possible in 83 (86%) of 96 patients with amebic abscess. It appears that, although some sonographic features of amebic abscess differ from those of pyogenic abscess, these differences are not sufficient to allow a specific diagnosis on the basis of sonography alone. Sonography can expedite abscess detection and, when coupled with clinical and laboratory data, can aid in differentiating pyogenic from amebic liver abscesses.

An unusual presentation of spontaneous pneumoperitoneum secondary to the rupture of a gas-containing pyogenic liver abscess: report of a case.

We describe a rare case of spontaneous pneumoperitoneum secondary to the rupture of a gas-containing pyogenic liver abscess in a 59-year-old man. The patient was diagnosed as having a hollow viscus perforation based on a sudden onset of acute abdominal pain along with radiological evidence of bilateral subphrenic feee air (pneumoperitoneum), and underwent an emergency laparotomy. Contrary to expectations, the surgery revealed no perforations of the hollow viscus, but instead a ruptured liver abscess at the dome of the right hepatic lobe was identified associated with suppurative peritonitis. To the best of our knowledge, such a case of spontaneous pneumoperitoneum secondary to the rupture of a gas-containing liver abscess is extremely rare.

Pyogenic liver abscess. Diagnostic and therapeutic strategies.

A retrospective review of 26 adult patients admitted to University of California, Davis, Medical Center (UCDMC) with pyogenic liver abscess (1980-1986) was performed to ascertain the impact of rapid diagnosis and percutaneous drainage. Ultrasonographic examinations and computed tomography (CT) scans were highly sensitive and noninvasive imaging modalities. Sixteen patients had solitary abscesses and seven had multiple microscopic abscesses. The median time interval from admission to diagnosis and therapy was 2 and 3 days, respectively. Origin of the abscess was determined in 22 patients, the biliary tree being the most common source. Medical therapy was successful in three patients with microabscesses but failed in two. Nine patients had percutaneous drainage; two required repetitive percutaneous catheter placement, and two proceeded to surgical drainage. Twelve patients had surgical drainage; one required repetitive surgical drainage. Postdrainage complications were minimal in all groups. Overall mortality role was 11.5% (two patients). Deaths were related to delay in diagnosis, gram-negative sepsis at presentation, and biliary origin of the abscess.

Comparison of pyogenic liver abscess caused by non-Klebsiella pneumoniae and Klebsiella pneumoniae.

From January 1996 to April 2002, a total of 248 patients with pyogenic liver abscess were enrolled in this study. Abscesses caused by Klebsiella pneumoniae accounted for 69% (171) of cases. Abscesses caused by K. pneumoniae were more strongly associated with diabetes mellitus or impaired fasting glucose than liver abscesses caused by non-K. pneumoniae (70.2% vs 32.5%). Solitary abscess and monomicrobial isolates were more frequent in the K. pneumoniae group than that in the non-K. pneumoniae group. A total of 42 patients were treated with antibiotics alone. Antibiotics treatment was combined with other procedures, including single aspiration in 23 patients, percutaneous drainage in 176 and surgical drainage in 7. A higher incidence of metastatic infections occurred in the K. pneumoniae group than in the non-K. pneumoniae group (14.6% vs 3.8%). By contrast, the mortality rate of the K. pneumoniae group was lower than that of non-K. pneumoniae group (4.1% vs 20.8%). There was no significant difference in the relapse rate between these 2 groups (6.5% vs 6.4%). We also found that the presence of respiratory symptoms (including cough, dyspnea, or chest distress), size of abscess > or =5 cm in diameter and non-K. pneumoniae pathogens were significant prognostic factors for mortality.
