We present our surgical technique for treating hepatic hydatidosis. This includes careful evacuation of the hydatid cyst through a wide capsectomy, interlocking suturing of the edges of the remaining cavity and postoperative drainage with negative pressure, closed drainage systems. During the operation, the abdomen is carefully isolated and strict precautions are taken to avoid spillage of hydatid fluid. Technical details on treating cystobiliary communications and exogenous daughter cysts are also described. As shown in our series, this method has very acceptable postoperative results, avoiding the complications of more aggressive operations, applied in other centres for the treatment of hydatid disease.
