A Case of Pyogenic Liver Abscess Complicating Cardiac Tamponade Caused by Klebsiella pneumoniae / 대한내과학회지

An 83-year-old female patient visited the emergency department for abdominal pain and dyspnea with hemodynamic instability. Abdominal computed tomography showed multiple liver abscesses and a large volume of pericardial effusion. A transthoracic echocardiography revealed features suggestive of cardiac tamponade, including massive pericardial effusion and diastolic collapse of the right atrial wall. Emergency percutaneous pericardial drainage and percutaneous transhepatic drainage were performed. Klebsiella pneumoniae (KP) was isolated from both the pericardial effusion and bile. The first case of cardiac tamponade secondary to a liver abscess in Korea was reported in 1981, and it was caused by amoebal infection via fistula formation between the pericardium and abscess. We recently experienced a case of pyogenic liver abscess caused by KP complicating cardiac tamponade via direct invasion. This is an unusual complication of KP infection because KP is more frequently associated with hematogenous spread.

A Case of Large Bile Duct Stones Complicated by Pyogenic Pericarditis, Liver Abscess, and Pyothorax / 대한소화기내시경학회지

The complications of bile duct stone are cholangitis, pancreatitis, obstructive jaundice, liver abscess, and secondary biliary cirrhosis. Liver abscess may produce pyothorax, peritonitis, subphrenic abscess, and pyogenic pericarditis. The case studies of pyogenic pericarditis secondary to pyogenic liver abscess are rarely reported. Stones greater than 20mm in diameter are difficult or impossible to remove with a standard basket or balloon after sphincterotomy. There are several nonsurgical treatment options for large bile duct stone: mechanical lithotripsy, endoprosthesis, extracorporeal shock-wave lithotripsy (ESWL), electrohydraulic lithotripsy, contact dissolution therapy, and laser lithotripsy. We experienced a case of large bile duct stone which complicated by pyogenic pericarditis, liver abscess, and pyothorax. He treated with antibiotics, closed thoracostomy, partial pericardiectomy, and removal of bile duct stones by extracorporeal shock-wave and mechanical lithotripsy after endoscopic sphincterotomy and nasobiliary drainage.
