在直肠镜冷光源指引下,用Nd:YAG激光切除、气化直肠息肉510例共688颗。结果直径<1 cm和直径≥1 cm但<2 cm的直肠息肉的一次性治愈率分别为90.8%和68.2%,有显著差异(P<0.01)。且后者有7例在术后3 d内有少量出血及激光性溃疡形成。提示直径<1 cm的直肠息肉用Nd:YAG激光治疗,方法简便,患者痛苦小,疗效好。反之,息肉直径≥1.0 cm者用Nd:YAG激光治疗,虽能治愈,但不能突出激光治疗的优越性,并且存在一定的风险。
Under the guidance of cold light source of rectal mirror, 688 rectal polyps were vaporized using Nd: YAG laser. Results The one-time cure rates of rectal polyps with diameters <1 cm and diameters ≥1 cm but <2 cm were 90.8% and 68.2%, respectively (P <0.01). And the latter 7 patients had a small amount of hemorrhage and laser ulceration within 3 days after operation. Rectal polyps diameter <1 cm with Nd: YAG laser treatment, the method is simple, the patient suffering little, good effect. On the contrary, polyp diameter ≥ 1.0 cm with Nd: YAG laser treatment, although can be cured, but can not highlight the advantages of laser treatment, and there is a certain risk.
