Treatment of Hydatid Disease of Liver with CE2 or CE3b Cyst >5 cm
This protocol applies to patients with uncomplicated hepatic cystic echinococcosis whose cyst is classified as WHO‑IWGE type CE2 or CE3b and measures more than 5 cm in diameter — a presentation for which active intervention is indicated.
For CE2 and CE3b cysts exceeding 5 cm, the recommended approach combines surgical intervention with antiparasitic pharmacotherapy — with the specific agents, perioperative schedule, and adjunctive measures for particular intraoperative circumstances detailed in the full protocol.
Response is assessed by cyst changes at 3 months — including detachment of the parasitic layers from the outer cyst wall, size reduction, or stage modification. Complete response is evaluated no earlier than 12 months after treatment end.

- In patients with uncomplicated hepatic cyst types CE2 or CE3b > 5 cm, surgery combined with ALB is suggested.
- This can be open surgery (in tiers 2–4) or laparoscopy (in tiers 3–4).
- A lack of response is defined as an absence of cyst changes after 3 months of treatment (detachment of the parasitic layers from the outer cyst wall, size reduction or stage modification).
- Complete response should be evaluated not earlier than 12 months after treatment end.
