BACKGROUND/PURPOSE: Surgery is the cornerstone in the treatment of echinococcosis. The purpose of this study is to report the long-term results of partial cystectomy and omentoplasty in the management of hepatic hydatid disease.
MATERIAL AND METHODS: In a retrospective survey over the past 20 years (1982-2001) there were 36 patients (13 men and 23 women, with a mean age of 50 years) with hepatic echinococcosis, treated by partial cystectomy and omentoplasty. All patient data were carefully studied and short-term as well as long-term results were assessed. The cystic lesion was single in all but two cases (5.6%), located in the right lobe of the liver (69.4%), the left lobe (25%) or both lobes (5.6%). The mean size of the cyst was 12 cm in diameter (range 3 to 25 cm). The follow-up was achieved at regular intervals and recently in all, including computed tomography and specific immunological test ELIZA. It has completed a mean 12-year period (range 2 to 21 years) and in 75% of cases up to 10 years.
RESULTS: The mean hospital stay was 23 days (range 9 to 51 days). The morbitity was 8/36 (22%) due mainly to septic complications. The 30-day mortality was 1/36 (2.7%). The residual cavity remained for a mean of 8 months (range 4 to 18 months), while fistula formation was seen in 1/36 (2.7%). There was cure in 29 cases (80.6%) without any serological or imaging evidence of residual disease. However, recurrence was documented in 7 cases (19.4%) requiring further treatment.
CONCLUSIONS: Following the experience of the authors, partial cystectomy and omentoplasty may be an acceptable alternative to more radical procedures, especially in high risk cases and in developing countries.
