Abstract:

Objective To investigate the clinical effect of modified ligation of the sphincteric fistula tract (LIFT) in the treatment of sphincter anal fistula. Methods According to the random number table, patients with perianal horseshoe abscess were randomly divided into two groups, the experimental group (by modified LIFT ) 50 cases and the control group (by classic operation) 50 cases. The operation

time, intraoperative blood loss, duration of the postoperative pain, hospital stay, healing time of surgical incision, anal function, anal morphology and recurrence rate of two groups were recorded and analyzed. Results The observation group was better than the control group in operation time, operation blood loss, postoperative pain duration, incision healing time, anal function and anal morphology, the difference wassignificant (P<0.05), but there was no significant difference in hospital stay and anal fistula recurrence

rate between the two groups (P>0.05). Conclusion Compared with the classic operation, it has good clinical effect to treat sphincteric perianal fistula through modified LIFT.
