A randomized controlled trial of trans-intersphincteric double seton (TRISDS) for the treatment of perianal abscess.

ABSTRACT:

Background

Incision and drainage (I&D) for perianal abscesses is associated with high rates of fistula formation. Our study aimed to evaluate the effectiveness of a novel technique, trans-intersphincteric double seton (TRISDS), designed to preserve anal sphincter integrity and improve clinical outcomes compared to I&D.

Methods

This prospective, randomized, non-blinded controlled study included adult patients with perianal abscesses located below the levator ani muscle with an internal opening. Patients were randomly assigned to either the TRISDS group (n = 55) or the I&D group (n = 51). The TRISDS technique involved two incisions: intersphincteric and drainage incisions with the placement of two loose setons. One seton was positioned to preserve the internal an
