Initial presentations and final outcomes of primary pyogenic liver abscess: a cross-sectional study.

ABSTRACT:

Background

Although pyogenic liver abscess (PPLA) fatalities are decreasing owing to early diagnosis and effective treatments, PPLA-associated complications still exist. The purpose of this study was to analyze the characteristic features of initial presentations and final outcomes of PPLA caused by different pathogens.

Methods

This retrospective study collected and analyzed information regarding initial presentations and final outcomes in patients diagnosed with PPLA at admitted at Changhua Christian Hospital from January 1 to December 31, 2010.

Results

During the study period, we analyzed the records of a total of 134 patients with documented PPLA. There were no significant causative pathogen-related differences in symptoms at initial presentation. Compared with the survivor group, patients in the mortality group were characterized by male gender (p < 0.001), malignancy (p < 0.001), respiratory distress (p =0.007), low blood pressure (p = 0.024), jaundice (p = < 0.001), rupture of liver abscess (p < 0.001), endophthalmitis (p = 0.003), and multiple organ failure (p < 0.001). No patients received liver transplantation or were diagnosed with HIV during the study period. According to univariate logistic regression analysis, gender (OR = 1.185, 95% CI: 0.284-11.130, p = 0.006), malignancy (OR = 2.067, 95% CI: 1.174-13.130, p = 0.004), respiratory distress (OR = 1.667, 95% CI: 1.164-14.210, p = 0.006), low blood pressure (OR = 2.167, 95% CI: 2.104-13.150, p = 0.003), jaundice (OR = 1.9, 95% CI: 1.246-3.297, p = 0.008), rupture of liver abscess (OR = 5.167, 95% CI: 2.194-23.150, p = 0.003), endophthalmitis (OR = 2.167, 95% CI: 1.234-13.140, p = 0.005), and multiple organ failure (OR = 3.067, 95% CI: 1.184-15.150, p = 0.001) differed significantly between the mortality and survivor groups.

Conclusion

Although the initial presentations of PPLA caused by different pathogens were similar, there were significant differences in mortality in cases involving: (1) male patients, (2) malignancy, (3) initial respiratory distress, (4) initial low blood pressure, (5) jaundice, (6) rupture of liver abscess, (7) endophthalmitis, , and (8) multiple organ failure. We strongly recommend using a severity score of the disease to determine the risk of mortality for each patient with PPLA. In order to prevent complications and reduce mortality, more attention must be paid to high-risk PPLA patients.

Project description:BACKGROUND: Commensurate 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. METHODS: The 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. RESULTS: The 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. DISCUSSION: Except 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.
