摘要
目的观察山田分型法对内镜下大肠息肉诊治的指导意义。方法收集内镜下行大肠息肉摘除术患者220例379颗息肉相关资料,观察息肉山田分型法与息肉大小、分布部位、病理类型(包括上皮内瘤变)、摘除方法及术后出血发生的相关性。结果山田分型中Ⅲ型息肉直径最大,病理结果Ⅰ型和Ⅱ型以管状腺瘤多见,Ⅲ型和Ⅳ型则以混合型多见,且Ⅱ型、Ⅲ型及Ⅳ型息肉上皮内瘤变发生率较高,息肉的不同分型采用摘除方法不同,内镜下大肠息肉摘除术后出血率2.9%。结论山田分型各型间息肉病理类型具有差异,不同分型息肉应选择适当的摘除方法,山田分型法对于内镜下大肠息肉的诊治具有指导意义。
[ Objective ] To evaluate the clinical value of Yamada classification guidance for endoscopic polypec- tomy of large intestine. [Methods] From January 2012 to December 2013, 220 patients with 379 intestinal polyps were assigned to four groups according to Yamada classification. The relevance of the Yamada classification to polyp size, position in the colon, the distribution of pathologic type （including intraepithelial neoplasia）, and endoscopic treatment, the hemorrhage rate were observed and registered. [ Results ] The polyp size of type III was the biggest. There were most tubular adenoma in type I and type II, but most mixed type in type III and type IV, the incidences of intraepithelial neoplasia were high except type I . Different methods were used for polyp of different classifica- tions, the rate of post-polypectomy bleeding was 2.9%. [Conclusion] Pathological types are different in four types according to Yamada classification, it is important to choose appropriate removal methods according to Yamada classification, Yamada classification guidance for polypectomy of gastrointestinal polyps is effective and feasible.
