Treatment of hydatid disease of the liver. Evaluation of a UK experience.

BACKGROUND

Hydatid disease of the liver though endemic in many countries, is rare in the UK. We evaluated a 16-year experience of treating hydatidosis using a management protocol combining surgery with anti-scolicidals.

PATIENTS AND METHODS

There were 30 patients. 14 (47%) males, median age 41 (range 25-72) years, of whom 21 (70%) were symptomatic. Diagnosis was by serological tests and imaging. All had disease confined to the liver and received peri-operative anti-scolicidal drug therapy.

RESULTS

The initial 4 (13%) patients received praziquantel combined with albendazole for 2 weeks and the following 26 (87%) patients received two cycles of albendazole 400 mg twice daily for 28 days, with a 14-day break in between. However, 2 (7%) patients could not tolerate albendazole, one due to GI side effects and the other developed deranged liver functions. These 2 patients subsequently received praziquantel for 2 weeks. All patients underwent surgery. Subtotal cystectomy was carried out on 29 (96%) patients and 1 patient required a segmentectomy. Cystobiliary communications were identified in 15 (50%) of patients which were oversewn using fine absorbable sutures. Of these, 7 had the bile ducts decompressed using a T tube, with only 1 developing a post-operative bile leak. In comparison, 8 were not drained of which 6 leaked (p = 0.03). The median post-operative hospital stay was 8 days (range 5-24). Patients who developed post-operative bile leaks, however, needed prolonged abdominal drainage for a median of 21 days (range 18-24). Two (7%) patients developed histologically proven recurrent disease. The median follow-up was 56 months (range 3-87).

CONCLUSION

Surgery combined with anti-scolicidal therapy proved effective. Cystobiliary communications are common and, when identified, should result in the biliary system being drained, to avoid post-operative bile leaks.
