Closure of Anal Fistula with Laser- FiLaC™: a Novel Sphincter-Saving Procedure for Complex Fistula In-Ano.

There are several surgical options described for the treatment of anorectal fistulas, specially in complex cases where recurrence rates and the possibility of postoperative complications are still high. Laser- FiLaC™ has been described in this study as an option in the management of anorectal fistula. The aim of this study was to assess the novel radial laser probe treatment in complex fistula in-ano and report the success rate and recurrence rate. We studied retrospectively 56 patients who, according to our hospital patient records, underwent radial laser probe surgery between March 2019 and August 2020. In a mean follow-up time of 6 months, the success rate at 2 months was 86.0%. Most operations were done under spinal anesthesia. The recovery time was rapid and median sick leave was 7 days. Of those initially successfully treated, 3.0% developed a recurrence. Altogether 4.0% of the patients underwent a re-operation. There is a good success rate using FiLaC™ treatment. FiLaC™ is very effective in treatment of complex fistula and as well as recurrence of fistula. It has a short hospital stay and as well as it is painless surgical technique that should be largely used in our country.
