Laser or excision
The anal canal is richly supplied with blood, so when excision of a polyp with a scalpel or loop, bleeding is possible, requiring suturing. The laser solves this problem: dissection occurs simultaneously with coagulation, the field remains dry, and the thermal impact zone is minimal. Healing is faster and with less scarring—this is important because rough scarring in the anal canal can cause it to narrow. A significant limitation: when the tissue is completely evaporated, there is no material left for histology. Therefore, for suspicious polyps, the doctor will prefer excision or take a biopsy before laser treatment.
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.
