Core Tip

Core tip: Approximately 10% of patients with alveolar echinococcosis experience hepatobiliary complications that occur on average 3.7 years (range: 0-41 years) following first diagnosis. Elevated hepatic transaminases in association with jaundice, abdominal pain, and weight loss are typical symptoms facilitating the diagnosis. Interventional endoscopic methods represent important options in these patients’ management. Even in cases of repeated interventions, the rates of complications and treatment-associated mortality are low. The average survival following onset of hepatobiliary complications and interventional treatment stands at 8.8 years.
