    Abstract:
    UNLABELLED: The aim of the study was to characterize the therapeutic pathways in patients with echinococcal hydatids in an institution outside the endemic areas but with a high frequency of oncological hepatic surgery. PATIENTS AND METHODS: 44 patients with echinococcosis from 1987-1997 were reviewed. To evaluate the long-term results, clinical examination, chest x-ray, serology and liver ultrasound were performed. According to the study protocol 39 patients were evaluable. 89.7 % of the patients suffered from a primary disease, whereas 7.7 had a local recurrence and another 2.5 of patients showed a second site of manifestation after former operation. E. cysticus occurred in 82.5 %, E. alveolaris in 17.5 %. RESULTS: In 66.7 % of all cases a resecting procedure (pericystectomy, atypic resection, regular and extended hemihepatectomy) was performed. One patient underwent an orthotopic liver transplantation and in 10 % the surgical procedure included only an open drainage of the cysts. A simple cystectomy was performed in 23 %. One patient died from multiple organ failure as a consequence of local bleeding complications. The overall complication rate was 38.5 %, including the postoperative death and 7.7 % reoperations. The complication rate following pericystectomy was much higher than after simple cystectomy. At the time of follow-up (median 66 months) no patient showed a recurrent disease. CONCLUSION: Compared to reports from endemic regions the rate of resective procedures was much higher. The therapeutic strategy lead to excellent long-term results. Simple cystectomy should be preferred as pericystectomy showed a higher morbidity.
