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.

[Amebic liver abscess: sonographic and clinical observations on 20 patients].

A retrospective analysis of 20 patients with amoebic liver abscesses was performed. Seven of 20 patients had more than one abscess. In all, 33 separate abscesses were observed. The diagnosis was based on clinical findings such as malaise, fever, abdominal discomfort, and pain in the right abdomen, haematological and serological anomalies, such as leukocytosis, elevated erythrocyte sedimentation rate, and slightly elevated liver enzymes. The serological investigation included complement fixation, indirect haemagglutination, and latex fixation test; this latter test produced strong reactions in all patients with acute symptoms. The typical ultrasonographic pattern resembled that of a minor echogenic lesion at the time of diagnosis and initiation of therapy. However, in a few acutely ill patients the lesions could not be identified by ultrasonography on first examination, but were clearly identifiable on second investigation on the following days. This finding has not been published previously. It may be observed in a very early stage of the disease only and is, therefore, dependent on rapid diagnosis of amoebiasis. During the follow-up investigations of three months to one year, the majority of abscesses could still be identified.

Multiple liver abscesses: an unusual case which demonstrates the importance of ultrasonography in the detection of liver pathology.

A 48-year-old caucasian male was admitted to hospital with right-sided chest pain, pyrexia and cough. He had no history of dysentery. He was treated with erythromycin and cotrimoxazole for right lower lobe pneumonia but failed to respond. Tender hepatomegaly developed and ultrasound scan demonstrated multiple abscesses in the liver. Entamoeba histolytica was identified in his faeces. He was treated with intravenous metronidazole, chloramphenicol and gentamicin and then oral tinidazole, after which improvement was rapid. He was later transferred to Australia. Subsequent abdominal CAT scan and aspiration of abscesses confirmed the diagnosis of multiple amoebic liver abscesses with secondary bacterial infection. Final treatment was with oral ciprofloxacin and metronidazole for four weeks. Ultrasonography is a noninvasive technique which is invaluable in the diagnosis of abdominal and especially liver pathology. This technique should be available in larger centres in tropical countries. Anyone living in or visiting the tropics should be aware of possible exotic diseases presenting in unusual ways.

A case of multiple cholangiogenic liver abscess due to residual biliary stone cured by percutaneous drainage controlled by CT and endoscopic papillotomy.

The case of a patient treated for multiple cholangiogenic liver abscess due to residual biliary stone after acute cholecystitis is reported. The multiple liver cyst was cured by percutaneous transhepatic double drainage controlled by CT as well as puncture and aimed local systemic antibiotic treatment. The residual gallbladder stone was removed by endoscopic papillotomy. A similar case has not been reported so far.

Liver abscess concomitant with hemobilia due to rupture of hepatic artery aneurysm: a case report.

Hepatic artery aneurysm is an uncommon lesion, usually extrahepatic and rarely intrahepatic. Rupture of hepatic artery aneurysm into the biliary tract is a rare cause of hemobilia. Angiography is the diagnostic method of choice and surgical intervention is the procedure of choice for extrahepatic rupture. Interventional angiography with embolization is optimal for inaccessible intrahepatic aneurysm and extremely poor risk patients. Reported here is a rare case of left intrahepatic artery aneurysm ruptured into the intrahepatic bile duct in the course of liver abscess. Embolization of the hepatic artery resulted in cessation of bleeding.

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.

Liver abscess caused by Edwardsiella tarda.

Edwardsiella tarda, among other Enterobacteriaceae, is a rare isolate from clinical specimens in man. A liver abscess caused by E. tarda was found in a middleaged woman without overt epidemiologic exposure to known reservoirs of this organism. While the most likely source of infection was the bowel, we failed to demonstrate a gut carriage of E. tarda or to show any local condition predisposing to the development of the liver lesion.

Amebic liver abscess: diagnosis and treatment evaluation with MR imaging.

Magnetic resonance images were obtained before and after treatment in 17 patients with 29 amebic liver abscesses. Pretreatment T1-weighted images showed a sharply circumscribed, heterogeneous, low-signal-intensity mass, devoid of normal hepatic tissue and corresponding to the abscess cavity as measured sonographically. T2-weighted images showed the abscess cavity as a hyperintense region and also showed a larger region of hyperintensity extending from the cavity margins to the liver surface, corresponding to edematous but morphologically normal liver tissue. After treatment, the abscess cavity became homogeneously hypointense on T1-weighted images, corresponding to liquefaction of the abscess center. With successful treatment, concentric rings corresponding to (a) an inner margin of inflamed granulation tissue, (b) bands of type I collagen, and (c) the outer margin of atrophic and/or mildly inflamed liver tissue became prominent on T1- and T2-weighted images. T2-weighted images showed rapid resolution of the perifocal hepatic edema.

Pseudomonas aeruginosa liver abscesses following endoscopic retrograde cholangiography. Report of a case without biliary tract disease.

We report a case of Pseudomonas aeruginosa liver abscesses following endoscopic retrograde cholangiopancreatography (ERCP) in a patient without evidence of biliary tract disease and of any known cause of hepatic infection. Computer tomography (CT) scan was the best method of diagnosis, allowing, through guided percutaneous puncture of the abscesses, isolation of the organism, which was sensitive to carbenicillin. One month of antibiotherapy with repeated aspirations of the largest abscesses was successful. This report suggests that ERCP may induce cholangitic sepsis by inoculating pathogens in the biliary tree even in the absence of extrahepatic obstruction.

Inflammation, complement, ischemia and amoebic survival in acute experimental amoebic liver abscesses in hamsters.

We have examined the role of inflammatory cells, ischemia and serum complement on the development of acute experimental amoebic liver abscess in hamsters (AEALAH). In hamsters made leukopenic by whole body radiation (800 rad) and daily intraperitoneal glycogen injections, the absence of inflammatory cells and liver tissue damage surrounding the parasites resulted in their rapid (24 h) disappearance from the liver, which showed no lesions. Focal liver ischemia, always present in control AEALAH with inflammation and tissue destruction, was reproduced in radiated hamsters by injection of amoebae mixed with Superdex microspheres, but again in the absence of inflammation, amoebae caused no liver damage and disappeared in 24 h. In hamsters made hypocomplementemic by injection of purified cobra venom factor (CVF), amoebae caused AEALA indistinguishable from controls, but in leukopenic + hypocomplementemic hamsters, amoebae were unable to produce lesions and disappeared from the liver in 48 h. We conclude that inflammation and tissue damage are required for the survival of amoebae in AEALAH and for the progression of the experimental disease.

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.
