Outpatient care is directed towards the following end points:

  • Chemotherapy: Postoperative treatment with benzimidazoles is continued for 1 month in patients with cystic echinococcosis (CE) who have successfully undergone complete resection or puncture, aspiration, injection, and reaspiration (PAIR). The treatment is continued for 3-6 months for patients with resected alveolar echinococcosis (AE), incompletely resected CE, spillage during surgery or PAIR, and metastatic lesions. Chemotherapy is needed for 3-10 years for patients with partially resected AE, unresectable AE, or liver transplant for AE.

  • Laboratory tests: Patients on benzimidazoles should have a complete blood cell (CBC) count and liver enzyme evaluation performed at biweekly intervals for 3 months and then every 4 weeks to monitor for toxicity. Enzyme-linked immunosorbent assay (ELISA) or indirect hemagglutination tests are usually performed at 3-, 6-, 12-, and 24-month intervals to assess for recurrence of resected disease or aggravation of an existing disease.

  • Imaging: Ultrasonography and/or computed tomography (CT) scanning are used in follow-up at the same intervals as the laboratory tests or as clinically indicated.
