Endoscopic Laser Surgery for Colonic Neoplasia
The potential role of endoscopically directed light amplification by stimulated emission of radiation (LASER) surgery for the palliative treatment of colorectal neoplasms and adenomas in selected patients is reviewed. This technique relies on the precise thermal destruction of exposed tissue. The depth of penetration is determined by the wavelength of the incident laser source, most commonly the argon laser or the neodymium YAG laser. In selected patients, because of the size configuration or location of a lesion, laser surgery appears to be a safe alternative to endoscopic diathermic removal or incisional surgery. This procedure has been well tolerated without complications. Nevertheless, the encouraging preliminary experience reported here is best regarded as palliative treatment.
