Results of hemorrhoidectomy by CO2 laser versus hemorrhoidectomy by surgical blade. To determine whether hemorrhoidectomy by CO2 laser has any superiority or not in comparison with hemorrhoidectomy by surgical blade, the authors reviewed 152 cases of hemorrhoidectomies within 3 years (1998-2000) at University Medical Centre. 83 cases were operated by CO2 laser and 69 cases were operated by surgical blade. By comparison the early and late results between the two groups, the authors recognized that hemorrhoidectomy by CO2 laser had relieved postoperative pain, apart from that, early and late complications were same.
