Minimally invasive laser therapy of anal fistula


Anal fistulas: minimally invasive treatment


Many people suffer from anal fistula (anal fistulas). An anal fistula is an abnormal channel between the bowel and the skin surface in the anal area. Via the outer opening, pus and in particular cases even faeces can be discharged.

It is supposed that anal fistulas spring from small anus‘ glands. If they get infected, a pus-filled socket is built which opens up a way for discharge. Rarely they are the result of a chronic inflammatory bowel disease. Anal fistulas can also appear in the aftermath of radiotherapy.

For some years now, it has been possible to have these removed with a state-of-the-art medical laser. The gentle FiLaC® laser method by biolitec® protects the sphincter muscle. Its function is retained and the duration of treatment is extremely shortened compared to conventional surgical methods. The procedure is almost painless and convalescence noticeably shorter than with conventional surgical procedures.

Anal fistulas should not be confused with pathologically enlarged hemorrhoids, although they are just as unpleasant. For information about hemorrhoids, see
