Pyogenic liver abscess: Retrospective analysis of 80 cases over a 10‐year period

A total of 80 patients with pyogenic liver abscess managed at a single institution over a 10-year period were studied.The clinical features, laboratory, imaging, and microbiologic findings, management strategy, and final outcome were studied.Fever and chills, leucocytosis and elevated alkaline phosphatase were the most common clinical and laboratory findings. Forty-one percent of patients were diabetic and 61% had biliary pathology. Systemic antibiotics and image-guided aspiration had a success rate of 94%. By multiple logistic regression analysis, malignancy on presentation (P = 0.011) was an independent risk factor associated with mortality. A past history of endoscopic sphincterotomy was an independent factor associated with resolution of liver abscess within 6 weeks (P = 0.03).Pyrexia, leucocytosis, elevated alkaline phosphatase, presence of diabetes, and underlying biliary pathology are common clinical and laboratory findings in patients with pyogenic liver abscess. Malignancy was associated with a poor outcome. Previous endoscopic sphincterotomy was a good prognostic factor for early resolution.
