Where does the stricture come from?
Narrowing of the anal canal is most often a consequence of previous operations - excessive excision of tissue during hemorrhoidectomy, as well as a consequence of long-term fissures, chronic inflammation and radiation therapy. It manifests itself as difficult defecation, ribbon-like feces, pain and a feeling of incomplete evacuation. The laser allows you to precisely cut scar tissue at the right points without damaging the sphincter muscle, and at the same time coagulate the blood vessels. After the intervention, a course of bougienage must be prescribed - without gradual stretching, the scar contracts again, and the result is lost.
What is removed in the perianal area
The most common findings are genital warts, anal canal polyps, anal fimbriae, atheromas and papillomas. All of them are removed on an outpatient basis under local anesthesia.
The general principle is the same: the formation is excised within healthy tissue and sent for histological examination - in appearance, a benign formation is not always distinguishable from a malignant one.
Scalpel or laser
Classical excision remains a reliable and universal method. Laser destruction works without contact: the beam evaporates the tissue and at the same time seals the vessels, so there is practically no bleeding, and healing proceeds faster and with less scarring. Limitation of the laser - when the tissue is completely evaporated, there is no material left for histology, therefore, in case of suspicious formations, excision is preferable.
After the procedure
During the first few days there may be discomfort during bowel movements. Soft stools, good hygiene and sitz baths are important. Most patients return to work the next day.
