A new surgical approach (subadventitial cystectomy) has been developed for liver hydatid disease. We retrospectively compared clinical outcomes and immune status 24 months after a subadventitial cystectomy with traditional surgical approaches. Patients with liver hydatid cysts were treated with a subadventitial cystectomy ( = 11), pericystectomy ( = 16), partial pericystectomy ( = 18), or hepatic resection ( = 12). By the end of the follow-up period, the subadventitial cystectomy group had the fewest post-operative complications and shortest hospital stays. Two recurrences occurred: one recurrence after partial pericystectomy and one recurrence after pericystectomy. The total immunoglobulin E (IgE) level decreased significantly in the subadventitial cystectomy group. The post-surgery IgG level was lower in the subadventitial cystectomy than the pericystectomy and partial pericystectomy groups. In conclusion, subadventitial cystectomy completely removes the parasite, causing lower complication rates and lower immune reactions.
