The comparative analysis by bronchial fistulae closure by hydatid lung cysts in children using two surgical techniques was conducted. All patients were divided in two groups: the first group (n=98) included cases of fistula closure using the traditional solitary Z-suture; the second group (n=54) had fistula closure with the use of the original method. The least was thoroughly described in the paper. The were no cases of postoperative complications among patients of the 2nd group, whereas 6 patients of the 1st group had bronchial fistula recurrence after the operation.
