Video Abstract DCR over LIFT

BACKGROUND: Ligation of the intersphincteric fistula tract is a well-accepted and often used surgical procedure for perianal fistulas. OBJECTIVE: This study aims to confirm results of the ligation of the intersphincteric fistula tract in a specialized colorectal center. DESIGN: This is a retrospective cohort study. SETTING: This study took place in a large colorectal surgical department with a tertiary referral center for perianal fistulas. PATIENTS: Consecutive patients were operated on with ligation of the intersphincteric fistula tract for a transsphincteric perianal fistula between 2012 and December 2018. INTERVENTIONS: Patients underwent ligation of the intersphincteric fistula tract. MAIN OUTCOME MEASURES: The primary outcome measured was the healing rate. The secondary outcomes measured were conversion into an intersphincteric perianal fistula, risk of recurrence, complications, and postoperative continence status. RESULTS: Forty-six patients were treated with a ligation of intersphincteric fistula tract procedure. All patients (100%) had preoperative imaging in their workup. Forty patients (87%) had a high transsphincteric fistula. The primary healing rate was a disappointing 17 of 46 patients (37%). The median time until failure was 4.2 months (interquartile range, 3.5-6.5). Of the failures, 16 converted to an intersphincteric fistula (55% of failures and 35% of all patients). The mean duration of follow-up in patients without a recurrence was 9.5 months (SD 11.9). Four patients (9%) were lost to follow-up. The mean Fecal Incontinence Severity Index postoperatively was only 2.35 (SD 5.7; range, 0-30). This resulted in 9 patients (20%) having a newly impaired continence status postoperatively. Continence impairment was mild in all these patients. The risk of developing a recurrence 1 year after surgery is 64.2% (95% CI, 49%-80%). LIMITATIONS: This study was limited by its retrospective design and the small numbers with possible selection bias. CONCLUSIONS: Results with the ligation of intersphincteric fistula tract procedure were not as good as hoped. The effect on fecal continence, however, was minimal. The procedure might be more suitable for low transsphincteric fistulas.
