[Risk Factors for Post-surgery Recurrence of Multiple Pulmonary Cystic Echinococcosis].

Clinical information of patients with multiple pulmonary cystic echinococcosis who received surgery in the Department of Thoracic Surgery of the Hospital from January 2005 to October 2014 was collected. Multivariate logistic regression analysis was used to analyze the predisposing factors for post-surgery recurrence of multiple pulmonary cystic echinococcosis. Among the 73 cases of multiple pulmonary cystic echinococcosis, 40 were males and 33 were females, with a male-to-female ratio of 1.21 : 1. The average age of patients was 37.6 years. All the patients reported a living history in pastoral areas or contacts with dogs. Thirty-eight patients were administered with albendazole tablets or liposomal albendazole for 3 to 12 months after surgery. Recurrence occurred in 6 cases, with a rate of 8.2%. Multivariate logistic regression analysis revealed the preoperative rupture of hydatid cyst to be the risk factor for post-surgery recurrence. The administration of anti-hydatid drugs after surgery plays a protective role against recurrence, and may reduce the risk of recurrence.
