Among colorectal polyps, those of the sessile and villous type are said to bear a high frequency cancer degeneration. While surgery is considered the cure, alternative choices are to be offered in the presence of contraindications or lack of an informed consent. We analyzed the results of the "combined therapy" that requires the use of the ND-YAG laser following the ablation of the lesion with diathermic snare. We used an EV laser 132 with double wavelength to allow the ablation of flat lesions and minimize the risk of perforation. We included 12 patients with sessile colorectal polyps. In 9/12 complete eradication was obtained over a follow-up 11 months; of the remaining 3, 2 dropped out, 1 did not respond. Owing to the small series, the relationship between the successful eradication and the size of the polyp cannot be evaluated. We conclude that the treatment of sessile colorectal polyps with this combined approach may be a promising one.
