Pyogenic liver abscess. Diagnostic and therapeutic approach: a case report.
We report a case of liver abscess secondary to an asymptomatic, subacute appendicitis in a 51-year-old man. The general condition of the patient was altered but there were no gastrointestinal signs. Treatment consisted in broad-spectrum antibiotics, followed by surgical drainage of the abscess and appendicectomy.
[Pyogenic liver abscess. Analysis and follow-up examination of a personal patient sample 1981-1992].
From January 1, 1981 to January 1, 1992 a total of 30 liver abscesses were treated in the University Clinic for Surgery in Cologne. 23 patients underwent an primary operative treatment and seven patients received a controlled guided percutaneous drainage. During the observation period four patients (13.3%) died by the effect of the liver abscess. 20 patients (66.7%) were subjected to clinical, laboratorical and computertomographical post examinations. The primary rate of operation success amounted to 47.8%, that of controlled guided percutaneous drainage of 42.8% (NS). The secondary success rate (that means after successful operative reintervention) amounted to 86.9% by the operative and to 85.7% by the percutaneous drainaged cases. During the post examination no relapse was determinated. Larger or chambered liver abscesses as well as extrahepatic spreading required operative drainage and, in cases of multifocal spreading, a resection with concomitant antibiotics. In case of solitary abscesses the controlled guided percutaneous drainage is the least harmful and low-prices method.

Resolution of liver abscesses: comparison of pyogenic and amebic liver abscesses.
To examine the resolution of liver abscesses, a prospective ultrasonographic follow-up study was conducted in 51 patients, each with a solitary abscess (26 pyogenic and 25 amebic) which had been treated successfully by non-surgical measures. The rate of complete abscess resolution for each of the initial 6 months was 0%, 5%, 10%, 23%, 30%, and 30% in the amebic group; and 20%, 54%, 77%, 89%, 94%, and 94% in the pyogenic group. The absorption volume of the pyogenic group in the first month was also greater than that of the amebic group (3.0 +/- 5.0 ml/day vs. 1.1 +/- 0.8 ml/day, P less than 0.05). The resolution ratio of pyogenic and amebic liver abscesses in the first month was 74% +/- 38% and 36% +/- 23%, respectively. In 3 patients in the amebic group, the abscess was still detectable 2 years after treatment. These results suggest that pyogenic liver abscesses resolve more rapidly than amebic abscesses. These findings should be considered in the differential diagnosis of asymptomatic space-taking lesion in the liver.
Ultrasonic features of pyogenic and amoebic hepatic abscesses.
Pyogenic liver abscesses are not infrequent in some developing countries. Amoebic abscesses may also occur in endemic areas and differentiation may be difficult. The ultrasonic data of proven cases of both conditions were compared and we are now more more confident in predicting the aetiology of these lesions.
Blunt trauma and liver abscess.
Three cases of pyogenic liver abscess following blunt trauma to the torso are described. The association between blunt trauma with liver contusion and the development of bacterial pyogenic liver abscess is explored. Reported series of liver abscess are reviewed. It is suggested that physicians look for the development of liver abscess in patients who have had major blunt trauma to the torso. Physicians should also inquire about blunt trauma in patients with documented pyogenic liver abscesses.
[Sonographic percutaneous drainage of liver abscesses].
13 patients with pyogenic liver abscess and five patients with amoebic abscess underwent percutaneous drainage of the abscesses using the Seldinger (n = 8) or trocar technique (n = 11). The results showed that the trocar method was easier and faster to perform and well tolerated by the patients. No complications were observed despite of one case of transient peritonitis caused by a dislocated catheter. One patient with pyogenic liver abscess died of septic shock. All other patients were successfully treated, using local drainage and systemic antibiotic therapy.
Right colon adenocarcinoma presenting as Bacteroides fragilis liver abscesses.
Pyogenic abscesses of the liver occur in association with a variety of diseases. Sometimes they are caused by anaerobic infections of liver metastases. Uncommonly, however, multiple hepatic abscesses caused by anaerobic bacteria are the presenting signs of unsuspected colonic cancer in the absence of liver metastases. We report a 60-year-old man who presented with febrile cholestatic liver disease initially thought to be metastases. Repeated ultrasound-directed liver biopsies yielded a diagnosis of multiple abscesses. Bacteroides fragilis was grown from the liver specimen and the patient responded well to metronidazole treatment. Two months later, however, overt symptoms of large bowel disease led to the diagnosis of colonic adenocarcinoma. After a 6-month postoperative follow-up, the patient is free of liver metastases. Anaerobic liver abscesses should always alert the clinician to possible silent colonic cancer.
Hepatobiliary disorders presenting as fever of unknown origin in Cairo, Egypt: the role of diagnostic ultrasonography.
Among 130 patients with fever of unknown origin (FUO) studied from 1981 to 1985, 34 were diagnosed as having hepatobiliary disorders: amoebic liver abscess (11), pyogenic liver abscess (4), hepatic hydatid cysts (2), hepatic fascioliasis (2), tuberculous hepatic granulomas (1), chronic calcular cholecystitis with recurrent cholangitis (2), chronic active hepatitis (2), hepatocellular carcinoma (3), lymphoma involving the liver (4) and hepatic metastasis in (3) cases. Hepatobiliary disorders were the cause in 27% of FUO seen during 4 years.
Hepatobiliary infections.
The major hepatobiliary infections (excluding the viral hepatitides) include amebic and pyogenic liver abscess and cholangitis. Little new information has been published in the area of cholangitis during the last several years. In contrast, the clinical presentation and management of liver abscess have evolved considerably, not only in the last several years but also during a more extended period spanning the last two decades. In the United States, amebic liver abscess occurs largely in individuals from endemic areas or in those traveling to endemic areas. Recent data suggest that patients with human immunodeficiency virus (HIV) infection are at an increased incidence of amebic liver abscess. New serologic tests and molecular techniques are being added to the diagnostic armamentarium for amebic liver abscess. In most cases, amebic liver abscess is associated with an excellent prognosis (up to 100% survival) if properly managed. Pyogenic liver abscess, although commonly occurring in patients with known biliary tract disease, is often cryptogenic in origin (ie, no clear causal factor can be identified) or often is caused by underlying medical disorders. An emerging population of patients with pyogenic liver abscess includes those with complications of aggressive interventions (hepatic chemoembolization, cryoablation, liver transplantation). Pyogenic liver abscess was predominantly managed by surgical methods up until the early 1980s, but almost entirely has changed to being managed by interventional techniques; in 2000, this trend has continued. In contrast to amebic liver abscess, pyogenic liver abscess is associated with greater morbidity and mortality, ostensibly caused by the severity of the underlying disease in many patients. However, it should be emphasized that the prognosis of patients with pyogenic liver abscess, who do not have underlying comorbid conditions, is excellent.
