Amebic liver abscess is an uncommon disease in the northern states of North America with 11 cases seen among approximately 500,000 Mount Sinai Hospital admissions over a 16-year period. Five of 11 cases originated in, or had recently visited South America. In three of these, and two patients with concomitant intestinal amebiasis, the diagnosis was suspected on admission. Diagnosis after admission was rapid, mean 5 days, compared with a mean of 13 days in pyogenic liver abscess. There was a higher incidence of male patients, nine males versus two females which was greater than the excess found in our pyogenic abscesses, 22 versus 16. Multiplicity was less common than in pyogenic abscess, 27 versus 50%, respectively. All three patients with multiple abscesses survived with surgical drainage and antibiotic therapy despite numerous complicating factors, including secondary bacterial infection. One patient resolved with drug treatment only; all others were treated with drugs and concomitant drainage; surgical drainage in earlier cases, and percutaneous drainage more recently. There was a single postoperative death. Drug treatment is the first therapeutic modality, and if recovery is delayed more than 2 days percutaneous aspiration should be carried out. This was successful in four cases. Surgery should seldom be required with present methods of accurately localizing amebic liver abscess, but is essential for ruptured abscess with peritonitis, and liver abscess with associated intestinal problems such as toxic megacolon, colonic perforation, or fulminating colitis. There has been a significant reduction in mortality of amebic liver abscess over the past 50 years and particularly within the past decade.(ABSTRACT TRUNCATED AT 250 WORDS)  相似文献

Pyogenic Liver Abscess   总被引:6,自引:0,他引:6  
Opinion statement Pyogenic liver abscess is an important and often life-threatening disorder. It is commonly caused by underlying disease of the biliary system, but more frequently, no predisposing disorder can be identified. Its diagnosis requires a high index of suspicion and imaging of the liver. The optimal treatment of pyogenic liver abscess is percutaneous drainage and intravenous broad-spectrum antibiotics with activity against enteric aerobic and anaerobic bacteria. Blood and abscess cultures should be obtained and amebic liver abscess carefully eliminated when the diagnosis is in doubt. Surgical drainage, preferably laparoscopic, is reserved for patients with complicated abscesses or after failure of response to initial medical therapy. Possible primary predisposing conditions to pyogenic liver abscess, such as biliary tract disorders, should be sought and managed accordingly. Intravenous antibiotics should be administered for a period of 2 weeks, followed by a more prolonged course of oral antibiotics. The choice and duration of antibiotic therapy, and the need for further intervention are determined by microbiologic data, the patient’s clinical response, and repeated imaging studies.  相似文献

BACKGROUND: It is universally recognized that the most frequent cause of hepatic abscess is biliary disease. The aim of this study was to determine the efficacy of endoscopic drainage and local antibiotic lavage via nasobiliary catheter in the treatment of liver abscesses of biliary origin. METHOD: From January 1994 to December 1995, twenty-two cases of pyogenic liver abscess were treated. Diagnosis was established with ultrasound, computed tomography, endoscopic retrograde cholangiography, and laboratory tests. All patients were assigned prospectively to endoscopic or other non-surgical forms of therapy, depending on the etiology of the pyogenic process. Patients in whom this treatment failed underwent surgical drainage. Twenty patients had hepatic abscesses of biliary origin. In this subgroup, a nasobiliary catheter was placed into the biliary tree for continuous antibiotic lavage (infusion technique: 1 to 1.5 mL/min for 8 to 10 days) after endoscopic sphincterotomy. Two patients had hepatic abscesses of hematogenous and amebic origin, respectively. They were treated only with the appropriate systemic antibiotics. RESULTS: Nineteen patients of the biliary subgroup (95%) and the two patients with non-biliary disease (100%) had complete resolution of the abscesses. "Salvage" surgical drainage was required in only one patient (4.5%). There was no treatment related mortality. CONCLUSION: Endoscopic sphincterotomy and local antibiotic lavage via an endoscopically placed nasobiliary catheter is a safe and effective treatment for biliary liver abscesses. It should be considered as first-line treatment in this subgroup of patients with liver abscesses. Percutaneous or surgical drainage modalities should be reserved for patients in whom endoscopic treatment fails.  相似文献

This study aims to compare the therapeutic effectiveness of continuous catheter drainage versus intermittent needle aspiration in the percutaneous treatment of pyogenic liver abscesses. Over a 5-year period, 64 consecutive patients with pyogenic liver abscess were treated with intravenous antibiotics (ampicillin, cefuroxime, and metronidazole) and randomized into two percutaneous treatment groups: continuous catheter drainage (with an 8F multi-sidehole pigtail catheter); and intermittent needle aspiration (18G disposable trocar needle). There was no statistically significant difference between the two groups regarding patient demographics, underlying coexisting disease, abscess size, abscess number, number of loculation of abscess, the presenting clinical symptoms such as fever, abdominal pain, and pretreatment liver function test. Although not statistically significant, the duration of intravenous antibiotics treatment before percutaneous treatment was longer with the catheter group, and the change of antibiotics after the sensitivity test was more frequent with the needle group. The needle group was associated with a higher treatment success rate, a shorter duration of hospital stay, and a lower mortality rate, although this did not reach statistical significance. In conclusion, this study suggests that intermittent needle aspiration is probably as effective as continuous catheter drainage for the treatment of pyogenic liver abscess, although further proof with a large-scale study is necessary. Due to the additional advantages of procedure simplicity, patient comfort, and reduced price, needle aspiration deserves to be considered as a first-line drainage approach.  相似文献

OBJECTIVES: To study the variations of aetiology in the patients with acute pyogenic iliopsoas abscess and identify the appropriate diagnostic modalities as well as therapeutic alternatives (e.g. extraperitoneal or retrofascial percutaneous catheter drainage, PCD) other than surgery. METHODS: We carried out a retrospective review and analysis of 25 patients with acute pyogenic iliopsoas abscess in our institution from August 1988 to July 1998. Blood and urine cultures, imaging studies of the plain films of the abdomen (KUB), ultrasonography (echo) and computed tomography (CT scan) were performed in all patients. The therapeutic regimens included antibiotics only, PCD or aspiration, and surgery. RESULTS: The male to female ratio was 7: 18. The mean age was 64 years old. Diabetes mellitus (64%) was the dominant predisposing or associated factor. The most common aetiological source was urinary tract infection (52%) with enteric micro-organisms (Escherichia coli: 44% and Klebsiella spp.: 24%). Nineteen patients (76%) had pain in the abdomen, flank or back. Six cases (24%) were classified as 'primary' abscess, and only two patients survived. Nine cases were treated with antibiotics alone, only four responded and the others expired. Of the 15 cases receiving PCD or aspiration, five cases received subsequent surgical drainage or nephrectomy and survived. Another one case of Clostridia gas gangrene received emergency fasciotomy and expired. The total mortality was extremely high (11/25, 44%). CONCLUSIONS: We concluded that: (i) the aetiology of iliopsoas abscess may vary with the country of origin, with a preponderance of urinary tract infection in our Taiwanese series; (ii) a high index of suspicion is mandatory to enable early diagnosis of acute pyogenic iliopsoas abscess, particularly for older diabetic patients with fever, pain in the abdomen or flank, limp or flexion of the ipsilateral hip; (iii) CT scan can confirm the diagnosis and define the extent of the abscess; (iv) effective management should include appropriate antibiotic therapy and drainage of the abscess; (v) image-guided PCD should be tried first because of its low morbidity. However, should it fail, subsequent surgical drainage should be performed.  相似文献

Pyogenic and amebic liver abscesses are the two most common hepatic abscesses. Amebic abscesses are more common in areas where Entamoeba histolytica is endemic, whereas pyogenic abscesses are more common in developed countries. Pyogenic abscess severity is dependent on the bacterial source and the underlying condition of the patient. Amebic liver abscess is more prevalent in individuals with suppressed cell-mediated immunity, men, and younger people. The right lobe of the liver is the most likely site of infection in both types of hepatic abscess. Patients usually present with a combination of fever, right-upper-quadrant abdominal pain, and hepatomegaly. Jaundice is more common in the pyogenic abscess. The diagnosis is often delayed and is usually made through a combination of radiologic imaging and microbiologic, serologic, and percutaneous techniques. Treatment involves antibiotics along with percutaneous drainage or surgery.  相似文献

Thirty-six consecutive cases of liver abscess seen at the BP Koirala Institute of Health Sciences Hospital, Dharan, Nepal, from 1995 to 1998, were reviewed. Twenty-one cases were male and 15 female, with a mean age of 42 years. Twenty-four cases (66.7%) were amebic, 7 (19.4%) pyogenic, 3 (8.3%) indeterminate and 2 (5.5%) tuberculous. The most frequent clinical features included fever (88%), leukocytosis (66.7%), abnormal level of serum albumin (44.4%) and alkaline phosphatase (38.9%). The liver abscess was single in 61.1%, multiple in 27.8%, and in 66.7% of cases the abscess was present in the right lobe of the liver. Ultrasonography was diagnostic in all cases. A positive culture of the abscess was obtained in 7 cases (19.4%). The most frequent bacteria found were Klebsiella pneumoniae (4;11.1%), followed by Escherichia coli (3;8.3%). Two cases were due to Mycobacterium tuberculosis and none had malignancy. Percutaneous drainage was performed in 27 patients (75%). Mortality attributable to the abscess was 5.5%. We found percutaneous needle aspiration of liver abscess helpful in confirming diagnosis, as it provides a better bacteriological culture yield, gives a good outcome, and may uncover clinically unsuspected conditions like malignancy and tuberculosis. These two conditions should certainly be considered possible causes in our part of the world when an abscess fails to respond to standard treatment. In developing countries like Nepal, the clinical presentation of liver abscess has not varied over time. At present, rapid diagnosis and image-guided percutaneous drainage offer a better prognosis for liver abscess. We also recommend routine cytological examination of aspirated abscess materials, as well as stains and cultures for acid-fast bacilli.  相似文献

One hundred twenty-five cases of amebic liver abscess were diagnosed at Chang Gung Memorial Hospital in Taiwan from January 1981 to December 1989. An analysis of possible prognostic factors for severe amebic liver abscess was done retrospectively. The majority of the patients came from the southern part of Taiwan. Severe amebic liver abscess was defined as the rupture of an abscess that was resistant to 72 hr of medical treatment, or complicated by secondary bacterial infection. The results showed significant differences between patients with severe liver abscess and those with more moderate forms of amebic liver abscess in indices such as jaundice, hemoglobin and serum bilirubin levels, and dyspnea, as well as in pulmonary changes (right diaphragm elevation, right pleural effusion) seen on chest radiographs. Those patients with diabetes mellitus also had greater evidence of severe liver abscess. Moderate cases that were treated with amebicides showed excellent responses (no mortality). Severe cases required, in addition to amebicide therapy, either percutaneous or surgical drainage of pus, especially in those patients with ruptured abscesses. Those patients with abscesses that ruptured into the thoracic cavity were treated by either thoracostomy or needle aspiration, and all were cured. Three patients died of abscess rupture into the abdominal cavity, associated with secondary bacterial infection. The overall mortality rate was 2.4%. These symptoms and signs of severe liver abscess are indicators of the need for intensive treatment such as aspiration or surgical drainage.  相似文献

Hepatic abscess: changes in clinical, bacteriologic and therapeutic aspects   总被引:4,自引:0,他引:4  
Clinical, bacteriologic and therapeutic aspects of 53 patients with hepatic abscess seen from 1961 to 1973 are reviewed. Of these abscesses, 50 were pyogenic and 3 amebic in etiology. The mortality was 63 per cent; the greatest number of cases (38) and the greatest mortality (79 per cent) occurred in patients over 50 years of age. Thirty-five patients had macroscopic abscesses; in the remaining 18 the abscesses were microscopic in size. The most common causes of pyogenic macroscopic abscess were biliary tract infection (11 cases), direct extension from contiguous sites of infection (8 cases) and nonpenetrating trauma (5 cases). The causes of microscopic abscesses were biliary tract infection (9 cases), systemic bacteremia (8 cases) and pylephlebitis (1 case). Although the diagnosis was often obscure with nonspecific clinical and laboratory findings, the hepatic scintiscan and abdominal angiography were positive in all cases in which the abscesses were greater than 1 cm in diameter. Bacteria of bowel origin (particularly Escherichia coli, other Enterobacteriaceae and anaerobes) were the common etiologic agents. Staphylococcus aureus was implicated predominantly in children with bacteremia. Prolonged antibiotic administration and aggressive surgical drainage are the cornerstones of effective therapy.  相似文献

Distinguishing amoebic from pyogenic liver abscesses is crucial because their treatments and prognoses differ. We retrospectively reviewed the medical records of 577 adults with liver abscess in order to identify clinical, laboratory, and radiographic factors useful in differentiating these microbial aetiologies. Presumptive diagnoses of amoebic (n = 471; 82%) vs. pyogenic (n = 106; 18%) abscess were based upon amoebic serology, microbiological culture results, and response to therapy. Patients with amoebic abscess were more likely to be young males with a tender, solitary, right lobe abscess (P = 0.012). Univariate analysis found patients with pyogenic abscess more likely to be over 50 years old, with a history of diabetes and jaundice, with pulmonary findings, multiple abscesses, amoebic serology titres <1:256 IU, and lower levels of serum albumin (P < 0.04). Multivariate logistic regression analysis confirmed that age >50 years, pulmonary findings on examination, multiple abscesses, and amebic serology titres <1:256 IU were predictive of pyogenic infection. Several clinical and laboratory parameters can aid in the differentiation of amebic and pyogenic liver abscess. In our setting, amebic abscess is more prevalent and, in most circumstances, can be identified and managed without percutaneous aspiration.  相似文献

Twelve renal abscesses were treated with percutaneous aspiration (6 patients), percutaneous drainage (3 patients) or antibiotics alone (3 patients). The diagnosis was established based on computed tomography-guided aspiration in 9 cases and on radiographic findings and follow-up in the remaining 3. A bacterium was isolated in 2 out of 9 blood cultures, 2 out of 11 urine cultures and in all cultures of pus obtained by percutaneous aspiration. All patients had a good outcome. Our findings confirm the efficacy of percutaneous aspiration in the treatment of renal abscesses. Percutaneous drainage should only be considered when the abscess is very large or aspiration has failed.  相似文献

Three cases of pyogenic sacroiliitis are described, and the English literature from 1878 to 1990 reviewed, for a total of 166 cases. In 1 patient the source of infection was identified at the site of an intravenous line; 1 patient had 2 risk factors for developing the disease (pregnancy and intravenous drug use); and a third patient had no source of infection and no associated risk factors. The diagnosis of pyogenic sacroiliitis was made in each patient by history, physical examination, and positive skeletal scintigraphy or computed tomography of the sacroiliac joint. The infectious agent causing septic arthritis was identified by fine-needle aspiration of the sacroiliac joint under fluoroscopic guidance. Two of the 3 patients also had an open biopsy of the sacroiliac joint--one to confirm the organism causing septic arthritis, and the other for surgical drainage of the infected sacroiliac joint. Cultures from all 3 patients grew organisms uncommon for this disease, and all were treated for 6 weeks with intravenous antibiotics. In all patients pain diminished after treatment. Pyogenic sacroiliitis is a relatively rare condition (1-2 cases reported/year) that may be clinically difficult to diagnose unless the clinician is familiar with the disease. A prompt diagnosis can prevent significant morbidity and reduce serious complication. Major predisposing factors include intravenous drug use, trauma, or an identifiable focus of infection elsewhere, but 44% of patients have no predisposing or associated factors identified. Most patients present with an acute febrile illness with pain in the buttocks and pain on movement that stresses the affected sacroiliac joint. There is no specific blood test which points to the diagnosis of pyogenic sacroiliitis, although the erythrocyte sedimentation rate may be greater than 100 mm/hr. The diagnostic procedure of choice is bone scan with attention to the early perfusion phase, which usually localizes the affected sacroiliac joint. Unilateral involvement is the rule. In patients whose blood cultures fail to reveal a causative organism, fluoroscopic guided fine-needle aspiration of the sacroiliac joint under general anesthesia may help to identify the organism. If all cultures are negative, open biopsy of the sacroiliac joint may be required. Open biopsy should also be done if sequestration or an abscess is formed, or if the patient fails to respond to antibiotic therapy.(ABSTRACT TRUNCATED AT 400 WORDS)  相似文献

Objectives: To present the clinical and microbiological features of liver abscess after transarterial embolization (TAE) for hepatocellular carcinoma (HCC). Methods : We retrospectively reviewed records of 452 TAE procedures in 289 patients with HCC over a 2-yr period. Results : Four men and one woman with a mean age of 68.4 yr were diagnosed with liver abscess 1–8 wk (mean 4.6 wk) after the embolization. The incidence was 1.1% (5/452). Common symptoms included fever, chills, and right upper quadrant pain. Serum aminotransferase, alkaline phosphatase, and γ-glutamyltransferase levels and leukocyte count were frequently elevated. All the abscesses appeared as areas of hypodensity on CT scan and hypoechogenicity on ultrasonogram. The areas contained gas in the embolized tumor, which led to the suspicion and finally the diagnosis of abscess. In contrast to predominance of Gram-negative aerobes in sporadic pyogenic liver abscesses, the causative microorganism was predominantly Gram positive (60%). All patients were treated with parenteral antibiotics plus percutaneous aspiration, drainage, or operation, but one patient died from the abscess. Conclusions : For patients receiving TAE for HCC, few specific clinical or radiological features could readily differentiate patients complicated with liver abscess from those without. This may delay a timely diagnosis and lead to significant morbidity. Hence, in patients with risk factors, including old age, previous biliary tract disease, large tumor size (>5 cm), and gas forming in the embolized tumor, aspiration of the suspected focal hepatic lesion should be performed as soon as possible.  相似文献

Background/Aim:

Although liver abscess is more prevalent in developing countries than in developed countries, there is scant data about the characteristics of pediatric liver abscess in our region. We aimed to analyze the characteristics of pediatric liver abscess in our region and compare these with those of developed countries.

Materials and Methods:

The clinical features, laboratory, imaging, microbiologic findings, management strategy, and final outcome were extracted from the patients’ records retrospectively.

Results:

There were 18 cases of liver abscess including 16 pyogenic liver abscess, one amebic liver abscess and one candida liver abscess. Fever and abdominal pain were the most common clinical findings and leukocytosis was the most common laboratory finding. The most predisposing factors of liver abscesswere immune deficiency, minor thalassemia. Origin of liver abscess was appendicitis in two patients, the rest were considered as cryptogenic. While one patient was treated with antibiotics alone, five cases were taken for open drainage, and 12 cases were treated with percutaneous aspiration. Percutaneous aspiration failed in two patients who were later ttaken for open drainage, with an overall mortality rate of 5.5%. Conclusion: The overall characteristics of liver abscess in children in our society are not so different from developed countries. However, in contradiction to cases reported in developed countries, most cases of liver abscess were seen in healthy patients in our centre. Moreover, liver abscess was reported in our patients at a younger age and was more commonly seen in male children. Mortality rate was similar to that of developed countries.  相似文献

The presenting features, modes of treatment and clinical course were reviewed for 55 patients with pyogenic liver abscess, seen at Duke University Medical Center over a 15-year period. Thirty-three patients had a solitary abscess and 22 had multiple abscesses. Most patients were between the ages of 40 and 60 years. Males predominated, 2.4:1. Major underlying conditions included biliary tract disease, malignancy and colonic disease. Eight patients, each with a solitary abscess, had no identifiable underlying condition. Symptoms and signs were nonspecific: fever, chills, focal abdominal tenderness and hepatomegaly were common. A raised serum alkaline phosphatase level was the most consistent abnormal laboratory finding. CT with contrast enhancement, radioisotope scanning and ultrasonography all accurately defined solitary hepatic abscesses. However, CT scan was more successful than other imaging techniques in detecting multiple abscesses. In seven patients the diagnosis was made only at laparotomy. Overall, a diagnosis of liver abscess was made in 50 living patients (91%). Microorganisms were recovered from pus and/or blood cultures of 44 patients (80%). Most common were enteric gram-negative facultative rods, anaerobic gram-negative rods, and microaerophilic streptococci. Single abscesses were more likely than multiple abscesses to contain more than one organism. All patients received antibiotics; the choice of antibiotic does not appear to be critical provided the regimen has a broad spectrum including activity against anaerobes. Surgical or percutaneous drainage was successful when attempted in all patients with a single abscess, but the outcome was less favorable in those with multiple abscesses. Percutaneous drainage is currently replacing open operative drainage as the method of choice. Overall mortality in patients with single abscesses was 15% (5/33) and in those with multiple abscesses 41% (9/22).  相似文献

We report eight cases of amebic liver abscess. All patients were men, and four were homosexual. Five of the eight patients had syphilis, but the four homosexual patients who were tested for HIV infection were negative. Ultrasonography (US), with or without needle aspiration, is the best method for diagnosing amebic liver abscess, and the treatment of choice is US-guided needle aspiration of the abscess followed by metronidazole therapy. Complication by other sexually transmitted diseases is another important factor affecting the treatment of this disease.  相似文献

BackgroundLiver abscess is a serious disease traditionally managed by open drainage. The advances in interventional radiology over the last two decades have allowed a change in approach to this condition. We have reviewed our experience in managing liver abscess over the last 7 years.MethodsDetails of all patients admitted with liver abscess between 1995 and 2002 were prospectively entered onto our database. A review was performed to document the use of imaging and drainage techniques. Aetiology, morbidity, mortality and duration of hospital stay were recorded.ResultsForty-two patients (median age 53 [22–85] years; M:F 18:24) were admitted with liver abscess (multiple abscess 20); 19 cases were of portal tract origin, 16 cases were of biliary tract origin and 7 cases were spontaneous. Forty-one patients were managed non-operatively, all received antibiotics (cephalo-sporins 76%, metronidazole 88%, quinolones 33%). Diagnosis was made on ultrasound scan (22) or CT (20). Five patients were managed with antibiotics alone. Fifteen patients were managed initially with percutaneous aspiration and five subsequently required percutaneous drainage. Twenty-one patients had primary percutaneous drainage, nine requiring a further procedure (aspiration 3, drainage 6). One patient underwent hepatic resection. Median hospital stay was 16 (6–35) days. There was one death, but no procedure-related morbidity.DiscussionNon-operative management of solitary and multiple liver abscesses is safe and effective.  相似文献

Liver abscess can be caused by bacterial, parasitic, or fungal infection. Amebic abscesses are more common, but pyogenic abscesses account for three quarters of hepatic abscess in developed countries. Most common pathogens of the pyogenic liver abscess are Escherichia coli, Klebsiella pneumoniae, Bacteroides, Enterococci, Streptococci, and Staphylococci. However, liver abscess caused by Salmonella species has rarely been reported. We experienced a case of Salmonella liver abscess which improved after antibiotic therapy and percutaneous drainage. The patient was 52 years-old man who had an episode of intermittent fever, chills and epigastric pain for 2 weeks. He was diagnosed as liver cirrhosis eight years ago and diabetes three years ago. Salmonella group D, non-typhi was cultured from blood and pus from the liver respectively at the same time. With percutaneous drainage and susceptible antibiotic therapy, liver abscess decreased in size with improvements in fever and abdominal pain.  相似文献

A 49-year-old male who had been diagnosed as having amebic liver abscess when he was 32-year-old was admitted to our hospital with fever and watery diarrhea. Ultrasonography and CT examination demonstrated a solitary abscess in the right lobe of the liver. Cysts of Entamoeba histolytica were detected in the stool and an aspiration of the liver abscess looked like anchovy paste. Serum amebic antibody by the IFA method was positive and the case was diagnosed as amebic liver abscess. The patient was treated with metronidazole, and percutaneous transhepatic abscess drainage was performed. The liver abscess decreased remarkably in size and serum amebic antibody was negative after the treatment. Recurrence of amebic liver abscess is rare and we report this case with some literature.  相似文献
