PYOGENIC LIVER ABSCESS • Secondary to bacterial infection Etiology / route of dissemination • Biliary : cholangitis , ERCP • Portal: intra-abdominal; appendicitis, diverticulitis • Arterial: IVDU, pneumonia, endocarditis • Adjacent organ: cholecystitis • Direct trauma: after ablation on TACE Keep underlying tumor at the back of your mind specially if you don’t find a source!
PYOGENIC LIVER ABSCESS Clinical presentation • Fever • Abdominal pain • Nausea, vomiting, weight loss • Sepsis
PYOGENIC LIVER ABSCESS Diagnostic workup • Labs: leukocytosis and elevated LFTs • US • CT • MRI • Blood culture • Workup for source
PYOGENIC LIVER ABSCESS Treatment: • Antibiotics - IV - prolong course • Percutaneous approach - drain placement - aspiration (may need multiple trips to IR) • Surgical drainage/debridement/resection - failure of percutaneous approach - intra-peritoneal rupture - need for operative intervention to address other abdominal process
HYDATID LIVER DISEASE • Echinococcusspecies • Humans become accidental intermediate hosts when they become infected after ingesting ova passed in dog feces¹ • Liver is the most common involved organ² • It may take months to years for individual to become symptomatic after infection ¹William R.

HYDATID LIVER DISEASE Clinical presentation • Asymptomatic • RUQ pain • Allergic reaction and anaphylactic shock
HYDATID LIVER DISEASE Diagnostic work up • Laboratory - eosinophilia > 3% ¹ - LFTs may be normal - serology; electrophoresis, ELIZA • CT/MRI - multiple types -hydatid sand, honeycomb ¹Pitt HA, et al.: Management of hepatic echinococcosis in Southern California.

AMEBIC LIVER ABSCESS • Entamoebahistolytica • Most common extra-intestinal location • Fecal-oral transmission Killed Napoleon!!
AMEBIC LIVER ABSCESS Presentation • Asymptomatic • Abdominal pain and fever Unlikely to have concomitant colitis
AMEBIC LIVER ABSCESS Diagnosis: • US • CT • Serology ? Role of aspiration William R. Jarnagin and Leslie H. Blumgart, MD. Blumgart's Surgery of the Liver, Pancreas and Biliary Tract, 5th Edition Courtesy Professor A.K. El Dory, Ain Shams University, Cairo.
AMEBIC LIVER ABSCESS Treatment: • Metronidazole • Therapeutic aspiration - imminent rupture - failure or contraindication of medical treatment - secondary bacterial infection
LIVER FLUKE Fasciolahepatica • Fecal-oral transmission • Inhabit hepatocytes, bile duct, and gallbladder • Presentation: abdominal pain, fever, hemobilia • Diagnosis: CT, serology • Treatment - Triclabendazole - ERCP if biliary obstruction
LIVER FLUKE Clonorchissinensis • Fecal –oral transmission • Oriental cholangiohepatitis • CT, serology • Praziquantel
