Recurrence and long-term outcome after open cystectomy with omentoplasty for hepatic hydatid disease in an endemic area.
OBJECTIVE
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.


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.
