Comparing IFOC and LIFT surgery for high anal fistula.
Official title: Early Outcomes of Intra-anal Fistulotomy With Fistula Opening Closure (IFOC) Compared With Ligation of the Intersphincteric Fistula Tract (LIFT) in High Anal Fistula: A Pilot Randomized Controlled Trial
Run by Cairo University · NCT07520500 · Data updated 2026-11-12
This will test whether IFOC or LIFT surgery leads to better healing and continence for people with high anal fistula.

Is this trial a fit for you?
✓Likely a good fit
Adults of any gender with a high anal fistula (involving more than one-third of the sphincter complex) who do not have inflammatory bowel disease, colorectal cancer, prior fecal incontinence, or fistulas caused by trauma or radiation.
✕Probably not a fit
Patients with IBD, fistulas from cancer, pre-existing fecal incontinence, low anal fistulas, or those unable to attend follow-up are unlikely to benefit from participation.

What this trial studies
Adults presenting with high anal fistula at Kasr Al-Ainy Hospitals will be screened and have preoperative MRI fistulogram and continence scoring. Eligible participants will be randomly assigned 1:1 to receive either the LIFT procedure or the intra-anal fistulotomy with fistula opening closure (IFOC) using standard surgical techniques. Postoperative care will follow the same protocol for both groups with clinical follow-up to document healing, discharge, and continence using the Jorge-Wexner score. Patients with inflammatory bowel disease, colorectal malignancy, pre-existing fecal incontinence, traumatic or radiation-related fistula, or low fistulas are excluded.
Why it matters
Potential benefit: If successful, the comparison could identify the approach that best heals fistulas while preserving bowel continence.
How similar studies have gone: Previous studies of LIFT have generally shown good continence preservation with variable healing rates, while intra-anal closure approaches have produced mixed results, so comparative data are available but not definitive.
