Recurrence of hydatid disease

Abstract

Surgical management of hepatic hydatid disease has been associated with an overall local recurrence rate of approximately 10%. Local recurrence is rarely seen following complete resection of an intact cyst and is usually the result of spillage of live parasites or leaving a residual cyst wall containing germinal epithelium, daughter cysts, or protoscolices during surgery. Recurrence is frequently asymptomatic, so the diagnosis depends on dedicated follow-up of treated patients with serology and either ultrasonography or computed tomography. The management of locally recurrent disease should include administration of albendazole followed by the appropriate application of interventional radiotherapy or operation. As with the treatment of primary disease, the preservation of liver function and minimizing the risk to the patient remain the guiding principles of therapy of local recurrence.
