Comparative outcomes of standard laser fistula closure (filac) versus flac combined with advancement flap in the treatment of complex anal fistula.

Could you please clarify whether suturing the internal opening was done in the standard FiLaC technique applied to the patients in your study?

The preliminary publication at Research Square states that the internal orifice was closed with a suture. However, nothing was mentioned in the paper published this month at Techniques in Coloproctology.
