Liver abscess in patients with cirrhosis of the liver: a 12-year experience

Purpose. Liver abscess is rare in patients with cirrhosis of the liver. The aim of this retrospective study was to investigate the incidence, clinical presentation, causal pathogens, and outcome of liver abscess in cirrhotic patients. Methods. We collected 21 liver abscess specimens (from 14 male patients and 7 female patients; Child A: B: C, 4: 7: 10) from 22 731 admissions of 6450 cirrhotic patients, from 1986 through 1998. Results. The common clinical symptoms and signs included fever, chills, and abdominal tenderness. The major predisposing factors were biliary tract disease (52%) and diabetes mellitus (48%). The diagnosis rate with abdominal ultrasonography was 79%. Gram-negative aerobes were the predominant pathogens (Klebsiella pneumoniae, 66.7%; Escherichia coli, 23.8%), and occurred in 80% and 69% of blood and pus cultures, respectively, while 38% of cases showed polymicrobial pathogens. The location of the abscess was predominantly in the right lobe (71.4%), and 47.6% of patients had multiple abscesses. Six patients died (all with Child C cirrhosis). The overall mortality rate was 28.6% (6/21). Conclusions. The incidence of liver abscess in the cirrhotic patients was low, at 0.09% (21/22 731 admissions). The clinical presentations and pathogens were not different from those in noncirrhotic patients, except that in our cirrhotic patients, there was no significant difference in mortality between those with monomicrobial and those with polymicrobial abscess; nor was there a significant difference in mortality between those with single and those with multiple abscesses. The Child C patients were the high-risk group. Received: November 6, 2000 / Accepted: February 2, 2001     

Pyogenic liver abscess：An audit of 10 years’experience

AIM: To describe our own experience with pyogenic liver abscesses over the past 10 years and investigate the risk factors associated with failure of initial percutaneous therapy.METHODS: A retrospective study of records of 63 PLA patients presenting between 1998 and 2008 to Australian tertiary referral centre, were reviewed. Amoebic and hydatid abscesses were excluded. Demographic, clinical, radiological, and microbiological characteristics, as well as surgical/radiological interventions, were recorded.RESULTS: Sixty-three patients (42 males, 21 females) aged 65 (± 14) years [mean ± (SD)] had prodromal symptoms for a median (interquartile range; IQR) of 7 (5-14) d. Only 59% of patients were febrile at presentation; however, the serum C-reactive protein was elevated in all 47 in whom it was measured. Liver function tests were non-specifically abnormal. 67% of patients had a solitary abscess, while 32% had > 3 abscesses with a median (IQR) diameter of 6.3 (4-9) cm. Causative organisms were: Streptococcus milleri 25%, Klebsiella pneumoniae 21%, and Escherichia coli 16%. A presumptive cryptogenic cause was most common (34%). Four patients died in this series: one from sepsis, two from advanced cancer, and one from acute myocardial infarction. The initial procedure was radiological aspiration ± drainage in 54 and surgery in two patients. 17% underwent surgical management during their hospitalization. Serum hypoalbuminaemia [mean (95% CI): 32 (29-35) g/L vs 28 (25-31) g/L, P = 0.045] on presentation was found to be the only factor related to failure of initial percutaneous therapy on univariate analysis.CONCLUSION: PLA is a diagnostic challenge, because the presentation of this condition is non-specific. Intravenous antibiotics and radiological drainage in the first instance allows resolution of most PLAs; However, a small proportion of patients still require surgical drainage.     

Acute pyogenic iliopsoas abscess in children in Nepal

We describe a prospective study of twenty-four cases of acute pyogenic abscess of the iliopsoas in children treated conservatively and operatively. Eight patients were managed conservatively with antibiotics alone while sixteen others were managed operatively by open drainage. All made a complete recovery.     

Liver abscess: What determines the prognosis?

Records of all patients with liver abscess who presented to a teaching hospital between 1979 and 1986 were reviewed in order to determine prognostic factors and optimal treatment. Of 32 patients, the diagnosis was made ante-mortem in 30, and 24 patients survived. Patients who died tended to be older and more likely to exhibit confusion and other features of systemic toxicity at presentation. Fine needle aspiration, guided by computerized tomography, provided the correct diagnosis in 18 of 19 patients. Of 24 patients with isolated abscesses (1 or 2) 22 survived, whereas six of eight patients with multiple (more than 2) abscesses died ( P < 0.001). Aspirates from patients who survived appeared to grow anaerobes more commonly (NS), whereas those from non-survivors more often grew multiple organisms which usually included Gram-negative bacilli ( P < 0.01). All patients received broad spectrum antibiotics and a drainage procedure was carried out in 26. Of 19 patients treated by percutaneous drainage, 12 recovered, one required hepatic resection before recovering, and six died (four with multiple abscesses). Of nine patients (all with 1–2 abscesses) treated by open drainage, all eventually recovered, but three needed additional procedures. Six of eight non-survivors compared with four of 24 survivors had predisposing biliary sepsis ( P < 0.01). It is concluded that isolated liver abscesses are relatively benign, commonly grow anaerobes, and are usually resolved with antibiotics and drainage (closed or open), whereas multiple abscesses occur in sicker, older patients who are usually jaundiced with uncontrolled biliary sepsis. The prognosis in patients with multiple liver abscesses is poor irrespective of treatment.     

Liver transplantation: the Italian experience

BACKGROUND: Liver transplantation is the standard treatment for patients with end-stage liver disease no longer responsive to conventional medical treatment AIMS: To report the long-term experience of liver transplantation in Italy. PATIENTS AND METHODS: Data were obtained retrospectively by means of a multiple-item form collected from 15 Italian liver transplant centres. The filing centre was centralized. RESULTS: A total of 3323 liver transplants were performed on 3026 patients, with a cumulative proportional survival of 72.4%. Three, 5 and 10 years' patient survival rates were 72.3%, 68.8% and 61.3%, respectively. The most common indication for liver transplantation were hepatitis B virus (+/- hepatitis D virus)- and hepatitis C virus-related cirrhosis (59.4%). Excellent survival rates were observed particularly in controversial indications, such as alcoholic cirrhosis, hepatitis B virus-related cirrhosis and hepatocellular carcinoma. Retransplantation was required in 8.9% of the cases. The overall prevalence of acute cellular rejection episodes was 43.5%. In our study population, primary non-function and disease recurrence were the most common causes of graft failure (28.7% and 25.4%, respectively). Infections and/or sepsis were the most common causes of death after transplantation (42%). CONCLUSION: This study confirms that patients with controversial indications to liver transplantation such as alcoholic cirrhosis, HBV-related cirrhosis and hepatocellular carcinoma can achieve excellent survival when properly selected.     

Liver abscess caused by an unnoticed swallowed toothpick perforating the colonic wall

We present an unusual case of a liver abscess caused by a swallowed toothpick in a 43-year-old man. The abscess was first punctured under percutaneous ultrasound control and intraveneous administration of antibiotics whereas the diagnosis of the foreign body stuck in the sigmoid bowel wall was only made by a follow-up computed tomography since the patient had no complains indicating a colonic pathology. Even more, the patient did not remember ever having ingested a foreign body. The wooden toothpick was then successfully removed by endoscopy. The case report stresses the need for a search of the cause of unexplained liver abscesses and highlights the importance of computed tomography as the first imaging technique as the foreign body was missed on the ultrasound examination. Finally, the non-surgical treatment as first line management of liver abscesses will be discussed.     

Kusunda: an Indo-Pacific language in Nepal

The Kusunda people of central Nepal have long been regarded as a relic tribe of South Asia. They are, or were until recently, seminomadic hunter-gatherers, living in jungles and forests, with a language that shows no similarities to surrounding languages. They are often described as shorter and darker than neighboring tribes. Our research indicates that the Kusunda language is a member of the Indo-Pacific family. This is a surprising finding inasmuch as the Indo-Pacific family is located on New Guinea and surrounding islands. The possibility that Kusunda is a remnant of the migration that led to the initial peopling of New Guinea and Australia warrants additional investigation from both a linguistic and genetic perspective.     

Liver resection: 10-year experience from a single institution

BACKGROUND: Liver resection constitutes the main treatment of most liver primary neoplasms and selected cases of metastatic tumors. However, this procedure is associated with significant morbidity and mortality rates. AIM: To analyze our experience with liver resections over a period of 10 years to determine the morbidity, mortality and risk factors of hepatectomy. PATIENTS AND METHODS: Retrospective review of medical records of patients who underwent liver resection from January 1994 to March 2003. RESULTS: Eighty-three (41 women and 42 men) patients underwent liver resection during the study period, with a mean age of 52.7 years (range 13-82 years). Metastatic colorectal carcinoma and hepatocellular carcinoma were the main indications for hepatic resection, with 36 and 19 patients, respectively. Extended and major resections were performed in 20.4% and 40.9% of the patients, respectively. Blood transfusion was needed in 38.5% of the operations. Overall morbidity was 44.5%. Life-threatening complications occurred in 22.8% of cases and the most common were pneumonia, hepatic failure, intraabdominal collection and intraabdominal bleeding. Among minor complications (30%), the most common were biliary leakage and pleural effusion. Size of the tumor and blood transfusion were associated with major complications (P = 0.0185 and P = 0.0141, respectively). Operative mortality was 8.4% and risk factors related to mortality were increased age and use of vascular exclusion (P = 0.0395 and P = 0.0404, respectively). Median hospital stay was 6.7 days. CONCLUSION: Liver resections can be performed with low mortality and acceptable morbidity rates. Blood transfusion may be reduced by employing meticulous technique and, whenever indicated, vascular exclusion.     

Liver abscess and sepsis with Bacillus pantothenticus in an immunocompetent patient： A first case report

Bacillus species are aerobic, gram-positive, spore forming rods that are usually found in the soil, dust, streams, and other environmental sources. Except for Bacillus. anthracis (B. anthracis), most species display low virulence, and only rarely cause infections in hosts with weak or damaged immune systems. There are two case reports of B. cereus as a potentially serious bacterial pathogen causing a liver abscess in an immunologically competent patient. We herein report a case of liver abscess and sepsis caused by B. pantothenticus in an immunocompetent patient. Until now, no case of liver abscess due to B. pantothenticus has been reported.     

Liver abscess: a rare but an important complication that must be considered in Crohn's disease

Liver abscess is a quite rare complication in Crohn's disease. Early diagnosis and differentiation of pyogenic abscess from amoebic abscess are as important as the choosing of proper treatment in the management of liver abscess. Herein, 28-year-old man with Crohn's disease developing liver abscess is presented. He was treated with surgical drainage.
