The clinical presentations of liver abscess, hepatoma, and metastatic tumor to the liver may be quite similar, and procedures such as computerized tomography, radionuclide scanning, and ultrasonography of the liver cannot make a specific diagnosis. Therefore, we compared the clinical presentations of 38 patients seen during the last five years with liver abscess (13 patients), hepatoma (eight patients), and undifferentiated carcinoma metastatic to the liver (17 patients). Patients with liver abscess were distinguished from the other two groups by a significantly shorter prodrome, a history of known risk factors for liver abscess, fever, leukocytosis, and a normal-sized liver (P values all less than .1). A finding of three or more of these criteria correctly identified all cases of liver abscess. Only one of the 25 patients with neoplasms had three of the criteria. The presence of multiple or single lesions, abdominal pain, weight loss, or liver function abnormalities did not differ significantly among the three groups. Thus patients with liver abscess can be reliably differentiated from patients with hepatic neoplasms by clinical criteria alone, and appropriate empiric antibiotic therapy can be started while the diagnosis is being confirmed.

The first case of pyogenic liver abscess during pregnancy is described. Despite its rarity, this severe complication has to be considered when a febrile illness accompanied by upper abdominal pain and hepatomegaly occurs during pregnancy and puerperium. Diagnostic methods and treatment are suggested.

Twenty-four cases of pyogenic liver abscess admitted between 1977 and 1986 are presented. A mean age of 43 years (range 5-78) with a 3:1 male:female ratio and 25% mortality were noted. Fever and abdominal pain were encountered in over 80% of cases and anorexia and malaise in over 60%. Hepatomegaly and right upper quadrant tenderness were the commonest signs. Leucocytosis, raised alkaline phosphatase and gamma-glutamyl transpeptidase, and hypoalbuminaemia were each noted in roughly 80% of cases. None of these showed any prognostic significance. Predisposing factors were noted in 11 cases. No cases of associated biliary disease were noted. Multiple, polymicrobial, aerobic and mixed aerobic/anaerobic abscesses were associated with a higher mortality. Patients aged over 50 years or more also had a higher mortality (P less than 0.05). Anaerobic abscesses were often solitary and were associated with a lower mortality (P less than 0.05). Surgical drainage and guided percutaneous drainage showed no difference in morbidity.

A forty-eight year-old man complained of upper abdominal pain and diarrhea with mucinous bloody stool. He had not been abroad. Except high fever, anemia, leukocytosis and elevated rate of erythrocyte sedimentation, laboratory findings were not abnormal. Gastrofiberscopy showed the protrusion of gastric mucosa with a hollow on its surface in the angle. Abdominal CT scan and echogram revealed an abscess in the right hepatic lobe and an abscess in the left lobe. Ulceration and small protrusion of the rectal mucosa were found by romanoscopy. Stool examinations could not reveal amebas, but serological test for amebiasis by the Ouchterlony method showed positive. Under the diagnosis of the perforation into the stomach of amebic liver abscess, he was treated with Metronidazole and tetracycline. But, as a diffuse shadow appeared in the right thoracic cavity on the chest x-ray films with bloody sputa, perforation of amebic liver abscess to the right thoracic cavity was suspected. Laparotomy showed the communication of the abscess to gastric lumen. The post operative course was uneventful. We reported a case with the rare complication of amebic liver abscess.

Liver abscess is a rare complication following the ventriculoperitoneal (V-P) shunt operation. There has been only one case reported in the literature. We present a case of liver abscess developed about 3 months after V-P shunt operation. A 31-year-old female was admitted to our hospital in comatose condition due to second bleeding from an aneurysm of the right internal carotid artery on January 1, 1984. Obliteration of the aneurysm was performed on the following day. She received V-P shunt operation for the marked hydrocephalus on February 4, but she developed low spinal fluid pressure syndrome. She was able to walk by herself after the replacement of shunt valve on March 4. In the middle of April, she suffered from abdominal pain with a pyrexia for about 5 days. On May 13, a new peritoneal tube was placed in another part of the peritoneal cavity because of the recurrence of hydrocephalus. On the following day, she developed severe abdominal and back pains with a high fever. Abdominal CT scans and ultrasonogram were performed on May 22, showing a well-defined, cystic mass lesion in the liver and the peritoneal tube lying just beneath the mass lesion. Approximately 100 ml of white creamy pus was aspirated from the cystic mass by ultrasound-guided percutaneous puncture, and a 8.3 French pigtail nephrostomy catheter was left in place for 9 days until purulent drainage stopped. Microbiologic examination demonstrated staphylococcus epidermidis in the cerebrospinal fluid (CSF) from the shunt tube but was negative in the abscess fluid. The ventricular fluid was drained externally with the V-P shunt tube for a while, but the new ventricular drainage was instituted because of continuous positive cultures in the CSF from the shunt tube. Thereafter, the cultures of the CSF became negative and ventriculoatrial (V-A) shunt operation was performed on July 2. Postoperative course was uneventful. It is considered that the formation of the liver abscess seems to be caused by the focal injury to the liver surface by the insidiously infected peritoneal tube with St. epidermidis, and by the decrease in systemic resistance to infection. Percutaneous aspiration and drainage under the guidance of abdominal computed tomography or ultrasonography are very useful and efficient for the diagnosis and the treatment of liver abscess. When patients show signs of infection to the V-P shunt, we should remove the shunting system and place a new external ventricular drainage, and institute a V-A shunt after confirming negative cultures of the CSF.

27 patients who presented with pyogenic liver abscess from 1957 to 1984 are analyzed retrospectively and compared with the literature. Diagnosis and start of therapy were frequently delayed because of the unspecificity of symptoms. Symptoms included fever, abdominal pain, weakness, and loss of weight. In 50% of all patients, the abscess was found by chance at laparotomy or autopsy. The most frequent causes of abscess formation were cholestasis due to extrahepatic obstruction and intraabdominal infections. Frequently a predisposing condition such as carcinoma, diabetes mellitus or alcohol abuse was found. The overall mortality was 25%, and was higher in patients with multiple abscesses of the liver (36%) than in patients with solitary abscesses (10%). With the introduction of new imaging procedures (ultrasound, computer tomography), the abscesses can be punctured under view and the antibiotic therapy can be based on bacterial analysis. The causative bacterial organism could be identified by cultures of the abscess fluid and blood in up to 90%. The bacteria identified usually were identical to the intestinal flora. Using specific antibiotic therapy, surgical treatment is often unnecessary and can be reserved for abscesses resistant to conservative treatment and for those due to correction of the original source of abscess formation.

Twelve cases of liver abscess in children and adolescents presenting at Children's Hospital at Los Angeles from 1974 to 1983 were reviewed. Most occurred in children younger than 5 years of age. The time from onset of symptoms to presentation did not differ over the 10-year period examined. However, diagnosis was made more rapidly in the latter half of the decade due to the development of advanced noninvasive imaging techniques and serologic methods. A constellation of fever, abdominal pain (whether or not localized in the right upper abdomen), vomiting or anorexia, hepatomegaly, elevated white blood cell count and sedimentation rate, and an unexplained anemia should prompt the clinician to include occult liver abscess in the differential diagnosis and proceed to early use of ultrasound or isotopic liver-spleen scan. History of travel or immigration or exposure to food handlers harboring the infection is important to differentiate amebic abscess from bacterial abscess. This suspicion may greatly alter the course of treatment.

The presenting features of seven elderly patients with pyogenic liver abscess were reviewed retrospectively. Symptoms of malaise, anorexia and abdominal pain referrable to intra-abdominal pathology were present in only 43% cases and physical examination was frequently unhelpful. Leucocytosis, hyperbilirubinaemia and raised alkaline phosphatase were of diagnostic value in the majority of patients. Chest and urinary tract infections were frequent predisposing conditions. Antibiotic therapy for four weeks is adequate in elderly patients if combined with drainage procedures.

Infections with Entamoeba histolytica do not necessarily cause disease in those infected. The parasite may act as commensal (cysts living in the bowel) or it may cause a broad spectrum of clinical illness. Some of the factors causing overt disease are poorly understood. An acute amebic dysentery is accompanied by bloody stools, abdominal pain and indigestion. The most important extraintestinal complication of an amebic infection is a liver abscess causing severe pain, fever, nausea and vomiting. The diagnosis of an amebic infection is based upon isolation of the parasite from the stools. Extraintestinal amebiasis is diagnosed - apart from the clinical picture - by serology. For treatment of intestinal amebiasis so-called contact-amebicides can be recommended. An amebic abscess of the liver usually responds well to dehydroemetine, metronidazole or any other derivative or imidazole and chloroquine. Surgical treatment of amebic liver abscess is only required if complications arise.

We evaluated the efficacy and safety of ceftriaxone in 50 adults with serious infections, usually giving 1 g every 12 h. Of the 35 patients who could be evaluated for clinical efficacy, 15 had failed on previous therapy, 15 had nosocomial infections, and all but 1 had underlying diseases. One patient had three sites of infection. Favorable responses were seen in 34 of 37 infections, including 11 of 13 respiratory tract infections, all 7 urinary tract infections, all 12 skin and soft tissue infections, 1 of 2 bone and joint infections, a catheter-related septicemia, a liver abscess, and an otitis media and externa. Favorable bacteriological responses were seen for 48 of 58 organisms. This included 6 of 7 Staphylococcus aureus strains, 14 of 16 other aerobic gram-positive cocci, 18 of 20 Enterobacteriaceae, 6 of 9 Pseudomonas aeruginosa, and 1 of 2 anaerobes. Peak plasma ceftriaxone levels on day 1 were 152 micrograms/ml by bioassay and 78 micrograms/ml by high-pressure liquid chromatography. Four of the 31 initial isolates of aerobic gram-negative rods developed resistance to ceftriaxone on disk diffusion testing. Diarrhea occurred in 3 of 50 patients. All three had received a higher than usual dose. Drug administration was stopped twice, once for a thrombocytopenia and once for a thrombocytopenia with leukopenia. Neither problem could be attributed exclusively to ceftriaxone. Other adverse reactions were eosinophilia, abdominal pain, inguinal candidiasis, and nonsuppurative phlebitis. Even among debilitated adults, ceftriaxone was safe and effective in a twice daily regimen.
