[目的]探讨电子结肠镜下利用高频电治疗大肠息肉的临床效果。[方法]对56例大肠息肉患者在电子结肠镜下利用高频电治疗,并发出血者给予常规止血治疗,术后将切除息肉标本行病理检查。[结果]所有患者依据息肉数量均给予1次或者多次治疗均成功,并发少量出血2例,经再次电凝止血成功,未发生肠穿孔。切除93颗息肉中,腺瘤性息肉35颗(癌变6颗),炎性息肉21颗,绒毛状息肉13颗(癌变4颗),管状息肉31颗(癌变2颗),增生性息肉21颗,混合性息肉7颗(癌变1颗)。[结论]肠镜下利用高频电治疗大肠息肉是安全有效、经济实用的微创手术方法,值得临床进一步推广应用。 [Objective] To investigate the clinical effect of high frequency electrotomy for colorectal polyps under electronic colonoscopy. [Method] 56 cases of colorectal polyps were treated with high-frequency electrotransformation under electron colonoscopy and routine hemostasis was given to the blood recipients. Polyposis specimens were removed for pathological examination after operation. [Results] All patients were given 1 or more treatments according to the number of polyps, and 2 cases were complicated with a small amount of bleeding. After re-coagulation hemostasis was successful, no intestinal perforation occurred. Among the 93 polyps resected, 35 adenoid polyps (6 carcinomas), 21 inflammatory polyps, 13 villous polyps (4 carcinomas), 31 tubular carcinomas (2 carcinomas), 21 proliferative polyps , Mixed polyps 7 (cancer 1). [Conclusion] It is safe, effective and economical to use colonic polyps to treat colorectal polyps under colonoscopy. It is worth to be further popularized and applied clinically.
