Surgical treatment of pericyst in liver hydatid cysts.

The results of the surgical treatment of the pericyst in 94 patients with liver hydatid cyst are analyzed. Hepatic resections were performed in 2 patients, subtotal pericystectomy in 2 patients, partial pericystectomy in 65 patients, resection of the cyst dome in 9 patients and pericystodigestivostomy in 16 patients. The postoperative complications were statistically significant in complicated cysts (p < 0.001), in those with rigid walls (p < 0.001) and when lacking the adequate drainage (p < 0.01). The mean period of hospitalization was of 14 days in patients with supple pericyst and 40.1 days in those with rigid pericyst. Only one patient died of pulmonary embolism. In the absence of modern means of investigations and technical equipment in the treatment of the liver hydatid cyst, which is a benign disease, we have applied much simpler methods, but without vital risks.
