Surgical excision using the carbon dioxide laser and second-intention healing are often associated with good results and minimal complications. Healing usually occurs in 4-8 weeks. Use of the laser procedure is now advocated in patients with severe perianal hidradenitis suppurativa and the complex perianal fistula disease (PAD). With the carbon dioxide laser, lesions are ablated by vaporizing the tissue in layers until all macroscopically abnormal tissue is removed. This method effectively eradicates septic tracts and pockets while preserving sphincter function. The lesions are vaporized from the inside and out until surrounding healthy tissue is reached, superficially and deep. In this way, the technique can be tissue sparing and at the same time radical. [1] It also obviates diversion with or without proctectomy. [94]

Moreover, scanner-assisted carbon dioxide laser makes ablation quicker, smoother, and more precise and allows for early treatment of hidradenitis suppurativa lesions that were previously managed with less effective local conservative remedies. [95] Carbon dioxide laser treatment should be considered as a treatment option in patients with Hurley stage II. [96]
