During laser therapy, defined energy will be led into the fistula tract with help of an innovative laser probe. By this, the fistula tissue will be destroyed in a most sparing way and has not to be tediously extracted during a complex surgery by a surgeon. The laser probe is slowly pulled back step by step like a zipper, and the fistula is being closed. The highly flexible probe is suitable for the application even in wound tracts and can be applied independently from the length of the fistula tract. The laser treatment takes only a few minutes and provides the possibility to completely spare the enucleation of the fistula out of the healthy tissue.
After insertion of the laser probe into the fistula tract, the laser destroys the fistula tissue and closes the tract. The treatment is virtually painless, and the period of recovery is tangibly shorter than for conventional surgical methods.
The latest Distal Laser Proximal Ligation (DLPL) procedure for complex fistula-in-ano is a safe, relatively simple, minimally invasive, sphincter-saving procedure with a high chance of success. The laser Distal Laser Proximal Ligation (DLPL) applies energy to the pathway of the fistula tract. The 360° energy emission ensures homogenous photothermal destruction of the complex fistula tract, allowing safe closure. Any flap techniques can be performed before or after the laser application. The efficient radiation concept of the laser Distal Laser Proximal Ligation (DLPL) fiber makes optimal use of the laser energy applied. Optimal monitoring of the fiber tip is possible thanks to its excellent ultrasound visibility (if applied)
Our Patient had either a primary or a recurrent trans‐sphincteric Complex Anal fistula, a previously placed seton or a fistula involving a significant portion of the sphincter with a potential risk of postoperative incontinence on fistulotomy. The surgical procedure consisted of ‘sealing’ the complex fistula by laser energy. The primary end‐point was cure of the disease and evaluation of morbidity.
