Abstract

A review was carried out in Medline, LILACS and the Cochrane Library. Our database search strategy included the following terms: “hydatid cyst”, “liver”, “management”, “meta-analysis” and “randomized controlled trial”. No language limits were used in the literature search. The latest electronic search date was the 7th of January 2014. Inclusion and exclusion criteria: all relevant studies on the assessment of therapeutic methods for hydatid cysts of the liver were considered for analysis. Information from editorials, letters to publishers, low quality review articles and studies done on animals were excluded from analysis. Additionally, well-structured abstracts from relevant articles were selected and accepted for analysis. Standardized forms were designed for data extraction; two investigators entered the data on patient demographics, methodology, recurrence of HC, mean cyst size and number of cysts per group. Four hundred and fourteen articles were identified using the previously described search strategy. After applying the inclusion and exclusion criteria detailed above, 57 articles were selected for final analysis: one meta-analysis, 9 randomized clinical trials, 5 non-randomized comparative prospective studies, 7 non-comparative prospective studies, and 34 retrospective studies (12 comparative and 22 non-comparative). Our results indicate that antihelminthic treatment alone is not the ideal treatment for liver hydatid cysts. More studies in the literature support the effectiveness of radical treatment compared with conservative treatment. Conservative surgery with omentoplasty is effective in preventing postoperative complications. A laparoscopic approach is safe in some situations. Percutaneous drainage with albendazole therapy is a safe and effective alternative treatment for hydatid cysts of the liver. Radical surgery with pre- and post-operative administration of albendazole is the best treatment option for liver hydatid cysts due to low recurrence and complication rates.

Core tip: Hepatic hydatid disease still exists worldwide. Because of human migration, surgeons in developed countries are encountering patients with hepatic hydatid disease more frequently but may be unfamiliar with the treatment options for this condition. This review article is particularly important because there are no current updates of evidence-based practices for the treatment of hydatid cysts of the liver. Thus, a careful search of the published literature pertaining to this disorder was carried out.
