大肠息肉高频电切后的术后随访

目的了解大肠息肉高频电切后的复（再）发情况。方法大肠息肉高频电切术后每一年用电子结肠镜进行复查，疑有恶变者每3个月一次，随访时间1～7年，所有病例均取活检送病理。结果110例大肠息肉电切后，复（再）发37例（33．6％）；多发性腺瘤59例，复（再）发25例（42．3％）；单发腺瘤12例，复（再）发4例（33．3％）；大于或等于1cm的腺瘤30例，复（再）发22例（73．3％），小于1cm的腺瘤41例，复（再）发7例（17．1％）。结论大肠息肉高频电切后的复发与大小、病理及是否多发关系密切。术后定期复查很重要，对于大于或等于1cm的多发性腺瘤，建议术后半年至一年内复查。

Surveillance in patients snare polypectomy

Objective To investigate the role of snare polypectomy in preventing the recurrence of polyps. Metods Surveillance colonoscopy was taken yearly after the polypectomy. In suspected patients for malignancy, colonscopy should be taken every three months for a period of 1～7 years, and biopsies were taken for all cases. Results Recurrence was seen in 37（33.6% ） of 110 patients with metachronous polyps after snare polypectomy, in 25（42.3% ） of 59 patients with metachronous multiple adenomas after removal of synchronous adenomas, in 4 （33.3%） of 12 patients after the removal of single adenoma, in 22 （73.3%） of 30 patients with metachronous adenoma with diameter equal to or over 1 cm after the removal of adenoma and in 7 （ 17.1% ） of 41 patients with diameter smaller than 1 cm after the removal of adenoma. Condusion The recurfence of metachronous polyps is closely related to number, size and histological features of polyps. The surveillance should be taken in patients with diameter of polyps larger than 1 cm at an interval of half a year to 1 year.
