Amebic colitis is associated with serious complications and a high fatality rate if it progresses to its fulminant form. The purpose of this retrospective study was to determine the risk factors associated with fulminant amebic colitis. From February 1978 to February 1993, 60 adults were diagnosed with intestinal amebiasis at Chang Gung Memorial Hospital. Sixteen patients with massive bloody diarrhea, persistent systemic toxicity or signs of peritonitis were classified as having fulminant colitis, five of whom progressed to fulminant colitis after admission to the hospital. Forty-four patients with good responses to amebicides and without complications were classified as having moderate colitis. There was no amebiasis-related mortality among patients with moderate colitis. In contrast, five patients with fulminant colitis died. Early diagnosis and surgical treatment significantly decreased mortality when compared with conservative treatment. Significant factors associated with the development of fulminant intestinal amebiasis in univariate analyses were being male, age over 60 years, having an associated liver abscess, progressive abdominal pain, signs of peritonitis, leukocytosis, hyponatremia, hypokalemia and hypoalbuminemia. Only the factors of being over 60 years of age and hypokalemia were important in multivariate analyses. We conclude that early and extensive surgical treatment is mandatory for patients with typical presentations of fulminant amebic colitis on admission to the hospital, such as progression to peritonitis, persistent systemic toxemia and explosive bloody diarrhea. For other patients, especially the elderly and those with low serum potassium levels, close monitoring and observation for signs of fulminant colitis is important.

All 69 patients with amebic liver abscess that we treated in 1981-1992 were studied retrospectively. Men predominated by a 10:1 ratio. Of our 227 patients with amebiasis, some 30% yearly had liver involvement. The incidence peaked in 1988, decreasing later but increasing again in 1992. Most patients were 30-50 years old, the overall mean age being 45 years (range, 22-79), and decreasing with time. Patients with the related factors of travel abroad, positive results of a test for Treponema pallidum hemagglutination, and homosexuality have increased in number in recent years. Fever, abdominal pain, and hepatomegaly were the most frequent findings, and 39 patients had neither bloody stools nor diarrhea. Only 8 patients had had amebiasis previously. A solitary abscess in the right lobe of the liver was found in 40 patients. Entamoeba histolytica was found in the stool of 31 patients and in the pus of 39 patients. Sixty-one patients had positive results for an amebic serological test(s). The abscesses ruptured into the peritoneal cavity in 4 patients. All patients received metronidazole. Percutaneous or surgical drainage (or both) was done in 62 patients. The outcome was good, with 1 exception, and only 2 patients had recurrences.

A prospective study was undertaken to evaluate the clinical and sonographic patterns of resolution in amebic liver abscess (ALA). There were 146 patients of ALA attending the gastroenterology clinic of a tertiary care centre of whom 25 died. Of the remaining 121 patients, 107 were followed up for 20.9 +/- 11.4 months. 14 (11.3%) patients were lost to follow up before complete disappearance of the cavity. Complete disappearance of the cavity was seen in 84 (78.5%) and a reduction in volume to 50% at entry in 23 (21.5%). Abdominal pain, fever and hepatomegaly were the predominant forms of clinical presentation. On ultrasound, there were 121 cavities in 107 patients. The most frequent type of lesion was solitary, (96%) round cavity (80.4%) in the right lobe of liver (85%). Clinical and hematological parameters of resolution occurred rapidly (3.2 +/- 2.9 months). Sonographic resolution took much longer (9.6 +/- 6.8% months) in the 84 patients. The remaining 23 patients are on follow up. Three pattern of resolution were observed: Type I--where complete disappearance of the cavity occurred within 3 months (29.8%), Type II--where a gradual reduction and disappearance of the cavity occurred (64.3%) and Type III--where a rapid reduction till 25% of original cavity size remained and then a delayed resolution occurred (5.9%). There were no relapses in the patients on follow up. Factors that influenced healing time included the size of the abscess cavity at admission, hypoalbuminemia and anemia. The type of clinical presentation, nature of therapy, number or location of abscesses and time for clinical resolution did not influence the resolution time. None of the variables studied influenced the pattern of resolution. We conclude that rapid clinical resolution is common in patients with ALA. Sonographic resolution may be delayed and does not warrant additional or prolonged therapy.

In the period of 1989-1995 seven patients with amebic liver abscess were observed in Clinic of Infectious Diseases of Pomeranian Medical School in Szczecin. The diagnosis has been made on the base of epidemiological data, presence of intrahepatic defect by a scanning procedure of liver (ultrasonography, CT, scintigraphy) and positive serologic test for amebiasis. All patients were male of Polish nationality, 29-57 years old, who became ill after travel to Africa or India. Intestinal amebiasis was present only in two cases. Five patients had acute onset of disease and two chronic. The most common complaints included fever, abdominal pain, anorexia. A cough, chest pain, diarrhea or weight lose were less common. At physical examination paleness of skin, subjaundice, abdominal tenderness, hepatomegaly and sometimes pleural effusion have been observed. Laboratory tests revealed high RBS, leucocytosis and mild anemia. Slightly higher serum level of bilirubin, alkaline phosphatase were transient. Trophozoits of Entamoeba histolytica have been found in stool specimens of one only patient. Amebic antibodies tested with indirect hemagglutination (IHA) were present in all cases. Visual technics have shown abscess of 3 to 9 cm in diameter located at right liver lobe. Six patients have been treated with both chemotherapy (metronidazole or/and dehydroemetine) and "skin needle" aspiration. In two cases recrudescence of abscess has been observed after one and three years respectively. These two patients have been undergone second course of treatment with using not only needle aspiration and metronidazole/dehydroemetine but luminal agents as well.

A case with multiple liver abscess accompanied by massive portal venous gas is reported. A 61-yr-old male was admitted because of left lower abdominal pain, fever, and diarrhea. Abdominal x-ray examination demonstrated multiple branching lucencies in the liver. Computed tomography revealed multiple liver abscesses and massive gas in the portal system as well as a thickened wall of the sigmoid colon. Enema study using contrast medium revealed a perforation of the sigmoid colon with diverticulitis. The outcome was favorable after sigmoid colectomy in addition to intensive treatment with antibiotics. Bacteroides fragilis, which produces gas (H2 and NH3) by fermentation, was isolated not only from the resected specimen but also from blood samples. Although the presence of portal venous gas is a sign of poor prognosis in patients with intestinal infectious diseases, the sensitive detection of hepatic portal venous gas by computed tomography and the appropriate treatment may improve the patient's prognosis.

A total of 483 patients with pyogenic liver abscess during the years 1986 to June 1995 were studied at Chang Gung Memorial Hospital in Kaohsiung: 343 were a single abscess and 140 were multiple abscesses. Males were predominantly affected by this disease. Abdominal pain was more frequent with the single abscess than with multiple abscesses, and jaundice was more frequent with multiple abscesses. Blood levels of alkaline phosphatase, bilirubin, and creatinine and the white blood cell count were significantly higher in patients with multiple abscesses than in those with a single abscess; and the hemoglobin level was higher with single abscesses. The single abscess was usually larger than 5 cm, and the multiple abscesses were usually smaller than 5 cm. The single abscess was always located on the right side (72%) and the multiple abscesses always on the right or both sides. Single abscesses mainly had a cryptogenic origin (58.9%) and multiple abscesses a biliary origin (45.0%). Liver aspirates revealed Klebsiella pneumoniae, Escherichia coli, Streptococcus, Bacteroides, Enterococcus, among others. K. pneumoniae was more often found in a single abscess and E. coli more often in multiple abscesses. Percutaneous catheter drainage and aspiration comprised the main treatment initially, and the failure rate with multiple abscesses was higher than that with single abscesses. Surgical intervention should be considered for multiple abscesses because of the underlying disease. The overall mortality with multiple abscesses (22.1%) was higher than that with a single abscess (12.8%). Partial hepatectomy produced a low mortality rate for both single and multiple abscesses and should be considered in the presence of severe hepatic destruction by an abscess or a stone.

A 37-year-old man with fever, jaundice, severe right upper quadrant abdominal pain and impending septic shock was pre-operatively diagnosed to have hypoplastic right lobe liver with retrohepatic gallbladder, left hepatolithiasis and liver abscess by computed tomography. An urgent operation with cholecystectomy, choledocholithotomy, operative choledochoscopy and T-tube drainage was performed. Postoperative cholangiograms depicted multiple residual stones behind the sharply angulated biliary strictures in the medial branches of the left intrahepatic duct, which could not be eradicated by biliary dilatation via the T-tube tract. The left hepatolithiasis might be coincidental, or secondary to the congenital anomaly of the liver, because of the distorted biliary architecture, and the hypoplastic right lobe liver was associated not only with the retrohepatic gallbladder, but also with the much more complicated left biliary strictures and the hepatolithiasis behind them.

Hepatic actinomycosis is rare. We report an 86-year-old Japanese man with a 3-day history of high fever and anorexia who had an actinomycotic liver abscess complicated by disseminated intravascular coagulation (DIC). A definitive diagnosis was made when an Actinomyces species was cultured from aspirated pus. The clinical course was satisfactory. Treatment included prompt percutaneous drainage coupled with long-term intravenous administration of high-dose minocycline and piperacillin, combined with therapy for DIC. We reviewed 11 cases in Japan of Actinomyces involving the liver, including the case reported here. In most patients, there were no predisposing factors. Common symptoms and laboratory findings included fever, abdominal pain, leukocytosis, and elevated C-reactive protein. In 6 of the 11 patients a partial hepatectomy was performed because hepatic tumor was suspected. Five patients presented with a liver abscess. Hepatic actinomycosis should be considered in the differential diagnoses of pyogenic liver abscess and space-occupying lesions of the liver.

Amoebic liver abscess is a rare complication of pregnancy. It however, carries significant morbidity and because the diagnosis is often delayed, physicians in developing countries need to be reminded of its possibility when patients present with right lower chest and abdominal pain. This study presents the clinical reports of two cases in which the diagnosis was delayed and review the literature on amoebic liver abscess in pregnancy.

Two cases with spontaneous regression of a histologically confirmed hepatocellular carcinoma (HCC) are presented. This rarely seen phenomenon of a spontaneous tumor involution is discussed and compared with the current literature. The clinical symptoms were very similar to that of a liver abscess. A 56-year-old male suffered from a multicentric, highly differentiated, trabecular HCC. First symptoms were epigastric pain, septic fever and arthritis. The tumor marker AFP was constantly normal and no hepatitis could be verified. A resection of the tumor was performed. In patient 2, a 74-year-old male, a multicentric, clear cell HCC was found. The patient had completely recovered from hepatitis type B and within the liver tissue no viruses could be identified. Clinical symptoms were mainly characterized by upper abdominal pain and septic fever. AFP was excessively elevated (3850 ng/ml) but returned to normal preoperatively. In both cases, the specimen showed a subtotal necrotic HCC with insignificant amounts of vital tumor cells. Neither patient had a liver cirrhosis macroscopically, however patient 2 had local periportal fibrosis histologically. After 24 and 41 months of follow-up, respectively, both patients are in good health
