  1. *P value ≤0.05 was significant
  2. The mean differences of time of the recurrence between study groups including (group A and Group B) were shown in Table 7. There were no significant differences in means of time of the recurrence between study groups (29 months after operation in group A versus 27 months after operation in group B) (P = 0.778)
