Endoscopic drainage of pyogenic liver abscesses with suspected biliary origin

OBJECTIVES: Pyogenic liver abscesses remain an important and life-threatening clinical problem but their causes and management have changed over the last two decades. The aim of this study was to assess the feasibility and the impact of an endoscopic approach in the management of liver abscesses with suspected biliary origin. METHODS: We reviewed the records of 16 patients suffering from pyogenic liver abscess, who underwent endoscopic retrograde cholangiopancreatography (ERCP) in the setting of biliary diseases between January 1995 and December 2004. Nine patients had an underlying neoplastic disease; 13 had a history of biliary endoscopic maneuvers. When the collections were communicating with the biliary tree, an endoscopic drainage of the abscess was performed either by sphincterotomy, dilation, insertion of a nasobiliary catheter, or stenting. In noncommunicating liver abscesses associated with bile duct abnormalities, biliary decompression was obtained by insertion or replacement of biliary stents. RESULTS: Fourteen patients had liver abscesses communicating with the biliary system and underwent an endoscopic drainage of the cavity. Ten of these patients had an exclusive endoscopic drainage of the abscess, while four cases required additional percutaneous drainage. The two noncommunicating abscesses were associated with previous insertion of biliary stents; these were cured percutaneously after endoscopic stent replacement. Among the 16 patients, 13 had a rapid resolution of symptoms (81%). CONCLUSION: This initial clinical experience suggests that ERCP can demonstrate communications between the biliary tract and liver abscesses, and that an internal drainage of the cavity is feasible and safe.

Hepatectomy for pyogenic liver abscess

BackgroundCommensurate with the advances in diagnostic and therapeutic radiology in the past two decades, percutaneous needle aspiration and catheter drainage have replaced open operation as the first choice of treatment for both single and multiple pyogenic liver abscesses. There has been little written on the place of surgical resection in the treatment of pyogenic liver abscess due to underlying hepatobiliary pathology or after failure of non-operative management.MethodsThe medical records of patients who underwent resection for pyogenic liver abscess over a 15-year period were retrospectively reviewed. The demographics, time from onset of symptoms to medical treatment and operation, site of abscess, organisms cultured, aetiology, reason for operation, type of resection and outcome were analysed. There were 49 patients in whom the abscesses were either single (19), single but multiloculated (11) or multiple (19). The median time from onset of symptoms to medical treatment was 21 days and from treatment to operation was 12 days. The indications for operation were underlying hepatobiliary pathology in 20% and failed non-operative treatment in 76%. Two patients presented with peritonitis from a ruptured abscess.ResultsThe resections performed were anatomic (44) and non-anatomic (5). No patient suffered a recurrent abscess or required surgical or radiological intervention for any abdominal collection. Antibiotics were ceased within 5 days of operation in all but one patient. The median postoperative stay was 10 days. There were two deaths (4%), both following rupture of the abscess.DiscussionExcept for an initial presentation with intraperitoneal rupture and, possibly, cases of hepatobiliary pathology causing multiple abscesses above an obstructed duct system that cannot be negotiated non-operatively, primary surgical treatment of pyogenic liver abscess is not indicated. Non-operative management with antibiotics and percutaneous aspiration/drainage will be successful in most patients. If non-operative treatment fails, different physical characteristics of the abscesses are likely to be present and partial hepatectomy of the involved portion of liver is good treatment when performed by an experienced surgeon.     

Endoscopic ultrasound‐guided drainage of pelvic abscess without fluoroscopy guidance

Background and Aims: Few case series are reported on endoscopic ultrasound (EUS)‐guided drainage of pelvic abscesses under fluoroscopy guidance. We hypothesized that EUS‐guided drainage of pelvic abscesses without fluoroscopy is an effective alternative to surgery in patients whose abscesses are not amenable to percutaneous drainage techniques. The aim of this study is to evaluate the clinical efficacy of EUS‐guided trans‐rectal/transcolonic drainage of pelvic abscess without fluoroscopy. Methods: Fourteen consecutive patients with pelvic abscesses not amenable to percutaneous drainage underwent EUS‐guided drainage over a period of 22 months. Main outcome measures were the resolution of the pelvic abscess on repeat imaging and improved clinical symptoms. Results: Fourteen consecutive patients were enrolled. EUS‐guided aspiration was performed in three patients. In two patients, dilatation and aspiration was performed, while trans‐rectal stent was placed in nine patients. All patients became afebrile within 72 h. Stent was removed in all patients, after confirming the resolution of the abscess on repeat computed tomography after 7 days. One patient in whom only aspiration was done had recurrence of fever and abscess on the seventh day and was treated by surgical drainage. A follow‐up EUS done in 13 of the patients after 3 months revealed no recurrence, and all patients were asymptomatic at 6 months. The procedure was uneventful in all patients. Conclusion: Endoscopic ultrasound‐guided drainage without fluoroscopy is a safe and effective modality of treatment for pelvic abscesses not amenable to radiologically guided drainage, thus reducing the need for surgical intervention.     

ERCP and pyogenic liver abscess.

BACKGROUND: Liver abscess is commonly biliary in origin. We assessed the role of endoscopic retrograde cholangiopancreatography (ERCP) in patients with pyogenic liver abscesses. METHODS: Between January 1986 and December 1997, 63 patients with pyogenic liver abscesses were referred for ERCP. Twenty-one patients had a history of previous biliary procedures including cholecystectomy (21), biliary-enteric bypass (9), surgical sphincteroplasty (5), and endoscopic sphincterotomy (2). Demographic data, clinical features, biochemical parameters, treatment, clinical progress, and follow-up were recorded and analyzed. RESULTS: Two patients required laparotomy and 61 patients underwent guided aspiration and/or drainage at a median interval of 3 days after presentation. ERCP was performed at a median of 8 days (range 1 to 69 days) after initial treatment and succeeded in 90% of cases with no associated complication or death. Abnormalities were shown in 29 (46%) patients: biliary obstruction due to stones or strictures (15), ductal dilatation alone (7), spontaneous choledochoduodenal fistula (3), communication between abscesses and biliary tree (3), and splaying of biliary ducts by space-occupying effect (2). No abnormality was found in 34 patients. Eight patients underwent endoscopic therapy including sphincterotomy (5), stone extraction (6), and nasobiliary drainage (2). Overall mortality rate from liver abscesses was 6%. CONCLUSIONS: ERCP is useful in the treatment of patients with pyogenic liver abscesses.     

Non-operative management of pyogenic liver abscess

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.     

A case report of a lung abscess as a rare complication of a pyogenic liver abscess

Rationale:A hepatobronchial fistula and lung abscess following a pyogenic liver abscess is a rare entity and it is not easy to diagnose this condition based on the symptoms and chest radiography.Patient concerns:An 81-year-old man presented with productive cough and dyspnea.Diagnosis:Chest radiography indicated increased opacities in the right lower lung field with an air-fluid level suggestive of pneumonia complicated by a lung abscess. Chest and abdominal computed tomography revealed an abscess in the right lower lung field that bordered an abscess at segment 7 of the liver. Tubography confirmed a fistula between the liver and lung abscesses.Interventions:Due to communication between 2 abscesses, transhepatic approach was done instead of transpleural approach to avoid complications.Outcomes:A liver abscess complicated by a lung abscess was resolved following percutaneous transhepatic drainage of the liver abscess and antibiotic administration.Lessons:Though uncommon, the lack of suspicion of sub-diaphragmatic liver abscess often lead to a delay in diagnosis and proper treatment. Our case implies the importance of computed tomography in early diagnosis of liver abscess in case of lung abscess in the right lower lung field.     

Features distinguishing amoebic from pyogenic liver abscess: a review of 577 adult cases

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.     

The role of percutaneous transhepatic abscess drainage for liver abscess

To evaluate the efficacy of percutaneous transhepatic abscess drainage (PTAD) as an initial choice of treatment for liver abscess, the medical records of 28 patients with liver abscess were retrospectively analyzed. The patients were predominantly men (23 of 28) with a mean age of 59 years (range, 19—86 years). Their chief complaints were fever (86%), right hypochondralgia (32%), and jaundice (11%). Fifteen of the 28 patients (54%) had hepatobiliary and pancreatic carcinoma, and 31% had postoperative liver abscess. PTAD was performed in 23 patients and surgical drainage in 5. The overall success rate for PTAD was 83%. The success rate for PTAD for patients with multiple abscesses was 83% (5 of 6), compared with a success rate of 82% (14 of 17) for patients with solitary abscess. The prognostic factors for survival were cancer and sepsis and the mortality rate for patients with cancer was 40% (6 of 15) while the mortality rate for patients with sepsis was 56% (5 of 9). As a complication of drainage, 1 patient (4%) in the PTAD group had pleural abscess due to the transpleural puncture. Our findings support the use of PTAD as the primary treatment for liver abscess, as it is safe and effective irrespective of the number of abscesses and the patient's condition.     

Non-surgical treatment of biliary liver abscesses: efficacy of endoscopic drainage and local antibiotic lavage with nasobiliary catheter

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.     

A case of Salmonella liver abscess]

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.     

Hepatobronchial fistula with percutaneous pyogenic abscess drainage of the liver

Percutaneous abscess drainage has been successfully used in the treatment of hepatic abscesses. We present a case of a posttraumatic pyogenic liver abscess treated by CT-guided percutaneous catheter drainage with an unusual complication of a hepatobronchial fistula. Patient management and the subtle roentgenographic features of this case are presented. Early signs of hepatobronchial fistula including paroxysms of coughing and a peculiar metallic taste during the performance of an abscessogram are reported.     

Liver abscess after implantation of dental prosthesis

Pyogenic liver abscesses are rare but a life-threatening important condition. Dental procedures constitute only rare cases of pyogenic liver abscesses, with only a few cases in the literature. We report a patient with liver abscess following a dental procedure. A 74 years old diabetic male patient was admitted to our hospital with complaints of fatigue, 40 ℃ fever, rigors and right upper quadrant pain, 3-4 d after a dental procedure. Physical examination revealed fever and tenderness in the right upper quadrant. Laboratory examination revealed leucocytosis, elevated erythrocyte sedimentation rate and Creactive protein and moderately elevated transaminases. An abscess was detected in radiological examination in the medial part of the left lobe of liver, neighboring the gall bladder. He was suc-cessfully treated with percutaneous abscess drainage and antibiotherapy.     

Percutaneous catheter drainage in drug-resistant amoebic liver abscess

This communication records our experience with the percutaneous catheter drainage (PCD) of 22 amoebic liver abscesses in 19 patients who had failed to respond to amoebicidal therapy. In one patient with a left lobe abscess, imminent rupture was an additional indication for drainage. PCD combined with amoebicidal therapy not only expedited recovery, but was curative in all 19 patients. There were no complications. We conclude that PCD is a most useful adjunct to drug therapy and recommend its routine use in the management of drug-resistant amoebic liver abscesses.     

Ascaris liver abscess in children

Background Liver abscess in childhood is a very challenging subject both for patients and doctors. In India, pyogenic liver abscesses have been found mostly in children, especially in rural areas. Liver abscess due to wandering ascarids is a common complication in children in Kashmir, although it is rare outside. Methods The study was carried over a period of 10 years at Sheri-Kashmir Institute of Medical Sciences Srinagar India. Ten cases of liver abscesses due to wandering ascarids in children were encountered. The children were aged 2 years to 13 years. Results 70% of the children were from rural areas. All ten patients presented with fever, while three patients presented with peritonitis. Ultrasonography was the main tool of diagnosis. All ten patients were managed by open surgical drainage. Conclusion We conclude that Ascaris infestation should always be kept in mind while dealing with liver abscess in children.

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.     

Amoebic liver abscess. Study of 20 cases with literature review

PURPOSE: The management of amoebic liver abscess includes antiamoebic drugs combined or not with percutaneous puncture or surgical drainage. This study was to suggest a decision tree for the therapeutic approach of such feature. METHODS: We report a retrospective analysis of 20 imported cases with amoebic liver abscesses admitted at the Department of Tropical Diseases during 1995-1999 at the Bordeaux University Hospital Centre, France, and a review of the literature. RESULTS: The twenty patients were 14 males and 6 females, mainly 20 to 40 years old. The clinical presentation was mainly accounting a painful liver enlargement with hyperthermia. The echographic picture was mostly represented by a unique liver element located at the liver right lobe. They were numerous in an HIV infected patient. Thirteen patients have been treated using a medical therapeutic approach. A percutaneous puncture has been necessary for 4 cases. A percutaneous drainage has been realised for two patients as regard to the persistence of the hepatalgia occurrence. A surgical drainage has been experienced by two patients after a lack of efficacy of a percutaneous drainage, after rupture of an abscess treated medically, respectively. A review of the literature and the analysis of the 20 cases history have been used to determine a therapeutic algorithm. CONCLUSION: The occurrence of immediate complications at onset must indicate a first line surgical drainage procedure. Beside this situation, risk factors for rupture must be assessed (high size abscess, pejorative localization), as well as poor prognosis feature (liver failure, bacteraemia). If no pejorative condition occurs, a first-line exclusive medical approach can be undertaken with a clinical efficacy evaluation at H72. Otherwise, the indication of the percutaneous drainage must be discussed.     

Endoscopic biliary drainage in patients with amebic liver abscess and biliary communication.

BACKGROUND: Percutaneous drainage or surgery is required when amebic liver abscess (ALA) fails to respond to medical management. In some of these patients, non-response may be due to communication of ALA with the biliary tree. This report describes our experience with the use of endoscopic biliary draining in such patients. METHODS: Medical records of patients with ALA undergoing either needle aspiration or percutaneous pigtail drainage were retrieved; the indications for drainage were: abscess volume exceeding 250 mL, a thin rim of tissue (< 1 cm thick) around the abscess, systemic toxic features and failure to improve on medical treatment. Patients with abscess drain output >25 mL/day persisting for 2 weeks or presence of bile in the drain fluid underwent endoscopic biliary drainage. RESULTS: A total of 115 patients with ALA underwent percutaneous treatment. None of the 25 patients with needle aspiration needed any further treatment. Of the 90 who underwent catheter drainage, the catheter could be removed within one week in 77 patients; the remaining 13 patients (median age 42 years, range 24-65; all men) had an abscess-biliary communication. In them, the median catheter output was 88 mL/day (range 45-347) and 54 mL/day (28-177) at 2 days and 2 weeks after catheter placement. The drain fluid contained bile in all 13 patients and in addition contained pus in 10 patients. Eleven patients had a solitary abscess and two had multiple abscesses. Cholangiogram showed biliary communication in all 13 patients. All patients were treated with placement of 10F biliary endoprosthesis or 10F nasobiliary drain. Pigtail catheter was removed within 1 week in 11 of 13 patients. CONCLUSION: In patients with amebic liver abscess communicating with the biliary tree, biliary stenting may hasten clinical recovery and allow early removal of liver abscess catheter drain.     

Cholangiocarcinoma Presenting as Pyogenic Liver Abscess: Is Its Outcome Influenced by Concomitant Hepatolithiasis?

Objective : The etiology of pyogenic liver abscess is changing. Malignant biliary obstruction has emerged as one of the most important causes. We explored the clinical course of pyogenic liver abscess caused by cholangiocarcinoma. Methods : The medical records of 19 patients with cholangiocarcinoma presenting as pyogenic liver abscess were reviewed. Of them, 57.8% (11 of 19) had concomitant hepatolithiasis. Escherichia coli and Klebsiella pneumoniae were the most common pathogens isolated from aspirates of the abscesses. Eight patients received percutaneous drainage, whereas 11 patients initially underwent surgical drainage because of the presence of ascites or coagulopathy or lack of awareness of the underlying cholangiocarcinoma. Results : Overall, the hospital mortality rate was 36.8% (seven of 19). Patients with hepatolithiasis had a hospital mortality rate of 54.5% (six of 11), compared with 12.5% (one of eight) in those without (   p < 0.01  ). Notably, 84.2% (16 of 19) of the patients died within 6 months after the diagnosis was made. Conclusions : Cholangiocarcinoma presenting as liver abscess has a dismal prognosis. Concomitant hepatolithiasis worsened the infectious process and adversely affected the survival.
