Clinical Research On Using Improving Lift Surgery (Tunnel-type Fistula Resection And Ligation) For The Treatment Of High Anal Fistula

Objectives:To observe and evaluate the clinical efficacy and safety of the Improving LIFT Surgery (Tunnel-type fistula resection and ligation) for treatment of high anal fistula.Methods:The randomized study was made in 62 patients with high anal fistula. The study group (31 cases) received the Improving LIFT Surgery and the control group (31 cases) received the treatment of Resection, Suture or Thread-drawing. Then observe the operating time、VAS score、infection、healing time、hospital stay、 hospitalization expenses、efficacy、anus functions and recurrence rate of each group.Results:There was no significant difference in the efficacy、infection、and VAS score on the 7、14 day between the Improving LIFT Surgery and the control group (P>0.05). The Improving LIFT Surgery needs longer operating time than the control group (P<0.05). However there were statistically significant differences in the hospital stay、hospitalization expenses、VAS score onl day、anus function、and recurrence rate of 3 months(P< 0.05).Conclusion:The Improving LIFT Surgery has the same efficacy with Resection, Suture or Thread-drawing for treating high anal fistula,and is better in anus function、hospitalization time、hospitalization expenses and the recurrence rate of 3 months. It is efficacy and safe,selectively use in fibrotic high anal fistula may be economical and reliable.
