BACKGROUND: Historically, the operative mortality associated with hepatic abscess was >50%. More recently, patients have been treated with percutaneous drainage; however, those failing conservative management are treated operatively. Our aim was to evaluate the outcome of operation for hepatic abscess in those failing conservative treatment or in those presenting as a surgical emergency. PATIENTS AND METHODS: This was a retrospective review of patients undergoing operation for hepatic abscess at the Mayo Clinic, Rochester, Minnesota from 1990 to 2003. RESULTS: Of 288 patients diagnosed with hepatic abscesses, 32 required operation. Percutaneous drainage was the initial treatment in 15 (47%). The remaining 17 were initially managed with operation. Operative indication was septic shock (41%), failed nonoperative management (31%), and failure to make a diagnosis (28%). Operation was drainage (62%) or resection (38%). The morbidity and mortality rates were 41% and 15.6%, respectively. Factors associated with increased operative mortality were shock (p=0.04), INR > 1.5 (p=0.03), WBC >15 000 (p=0.04), AST > 150 U/L (p=0.01), alkaline phosphatase >500 U/L (p=0.03), positive blood cultures (p=0.03), total bilirubin >2.0 mg/dl (p<0.01), multiple abscesses (p=0.01), and second operation (p<0.001). Factors not associated were extent of resection (p>0.10), peritonitis (p>0.10), intensive care admission (p>0.10), polymicrobial infection (p>0.10), and blood transfusion (p>0.10). CONCLUSION: Operative intervention is avoided in 89% of patients with hepatic abscess. Septic shock is the most common reason for operation. Patients with septic shock, INR>1.5, WBC>15 000, AST>150 U/L, total bilirubin >2.0 mg/dl, positive blood cultures, or alkaline phosphatase >500 U/L have increased mortality when undergoing operation for hepatic abscess.
