Rectoperineal Fistula Repair Through Perineal Approach, Martius Flap, and House Advancement Flap

A rectoperineal fistula (RPF) is a relatively rare, non-life-threatening form of anorectal malformation that nevertheless causes significant physical discomfort, and remains technically challenging for surgeons to treat. We present a case of a 72-year-old female with a history of a recurrent perianal fistula with multiple approaches including endorectal advancement flap previously attempted. Our procedure involved laparoscopic loop ileostomy with transversus abdominis plane (TAP) block, and RPF repair through the perineal approach with primary repair involving Martius flap and house advancement flaps. The patient tolerated the procedure well with no known peri-operative complications and resolution of stool incontinence at subsequent post-operative visits, the first within a month of the procedure. This case was used to demonstrate and highlight the surgical technique of the RPF repair by Martius flap. Informed consent was obtained from the patient for video recording for educational purposes.
