[Surgical treatment of hepatic alveolar echinococcosis].

INTRODUCTION

Alveolar hydatid disease is an uncommon parasitosis found in the northern hemisphere, caused by the larval stage of a tapeworm growing in the liver: Echinococcus multilocularis. It behaves like a malignant tumor, producing liver necrosis and invading the biliary tract, main vessels and surrounding structures.

METHODS

Review of the different therapeutic approaches in hepatic alveolar echinococcosis over 21 years in an epidemic area.

RESULTS

The various surgical approaches (all types of hepatectomy, palliative surgical procedures and liver transplantation) were combined with medical, endoscopic and radiological interventional treatment. Recently, asymptomatic forms were more frequently encountered.

CONCLUSIONS

The wide use of ultrasonography and specific serological tests have led to early diagnosis, allowing more curative hepatectomies.
