目的探讨射频治疗大肠广基、有基、亚蒂三种类型大肠息肉的疗效。方法采用射频治疗仪,经电子结肠镜活检孔对≥2 cm结直肠息肉共45枚多点对称部位,于息肉体部、顶部加用平射、压射射频治疗。结果在3~6个月的时间复查有4例于内在原部位发现2~4 mm息肉,活检结果为管状腺瘤及增生性息肉,再次进行射频治疗,随访2年无复发及癌变,仅2例出现少量暗红色血便,常规休息及一般治疗痊愈,无穿孔及大出血发生。结论内镜下射频治疗大肠息肉是安全可靠、经济可行的,值得推广应用。
Objective To investigate the therapeutic effect of radiofrequency on three types of colorectal polyps, including large intestine, base, and pedicle. Methods The radiofrequency ablation instrument was used. A total of 45 multi-point symmetrical sites of ≥2 cm colorectal polyps were detected by electronic colon biopsy. In the polyp, the top of the polyp was treated with radiofrequency and radiofrequency ablation. Results In 3 to 6 months, 4 cases were found in the inner part of the original location of 2-4 mm polyps, the biopsy results of tubular adenoma and proliferative polyps, and again RF treatment, followed up for 2 years without recurrence and cancer, only 2 Cases of a small amount of dark red bloody stool, regular rest and general treatment healed, no perforation and bleeding occurred.
