Abstract
Objective: To evaluate long-term results of ligation of intersphinteric fistula tract (LIFT) for anal fistula. Subject and method: The study was conducted descriptively prospectively and longitudinally all of transsphincteric fistula patients with ligation of intersphinteric fistula tract at 108 Military Central Hospital from February 2016 to February 2020. Result: 33 patients, average age 41.0 ± 12.3 years, male/ female 15.5/1, average length of diseases 11.5 ± 10.9 months. 97.3% of patients with high transsphincteric fistula, 63.6% of patients with preoperative abscess incision, 21.2% of patients with recurrent anal fistula, 87.9%, 9.1%, 3.0% of patients had 1, 2, 4 external opening, respectively. The mean operative time was 48.9 ± 11.5 minutes, 100% of patients with less pain after surgery according to the VAS scale. Average hospital stay 2.8 ± 1.2 days, mean healing time 3.1 ± 0.9 weeks, there was 1 patient (3%) recurrence, which had fistulectomy. Average follow-up time 21.1 ± 16.9 months, the assessing the degree incontinence anal scores before surgery, 2 weeks, 2 months after surgery respectively 0; 1.1 ± 0.3, 0.1 ± 0.3 points.
