摘要: 目的:探讨结直肠锯齿状腺瘤患者的临床、内镜及病理特点。方法:对52例结直肠锯齿状腺瘤的临床、内镜及病理特点进行回顾分析。结果:病变位于直肠19例, 位于乙状结肠13例, 位于直肠乙状结肠交界处2例, 位于降结肠6例, 位于横结肠8例, 位于升结肠3例, 盲肠1例;多发1例, 单发51例;腺瘤直径1~25 mm。52例中广基息肉32例, 亚蒂息肉15例, 有蒂息肉5例。病理学检查为单纯锯齿状腺瘤17例, 锯齿状腺瘤伴低级别上皮内瘤变33例, 锯齿状腺瘤伴局部高级别上皮内瘤变1例, 锯齿状腺瘤局部恶变1例。结论:结直肠锯齿状腺瘤临床症状无特异, 以单发广基息肉多见, 多见于直肠, 常伴上皮内瘤变。Abstract: Objective: To investigate the endoscopic and pathologic characteristics of 52 cases with the serrated adenoma of large intestine. Methods: The endoscopic and pathologic characteristics of 52 cases with the serrated adenoma of large intestine were retrospectively analysed. Results: Among 52 cases with serrated adenoma, there were 19 cases in rectum, 13 cases in sigmoid colon, 2 cases in the junction of rectum and sigmoid colon, 6 cases in descending colon, 8 cases in transverse colon, 3 cases in ascending colon and 1 case in cecum. One case with multiple adenoma and 51 cases with single adenoma were found, which diameters were 1 to 25 mm. Fifty-five cases with serrated adenoma included 32 cases with wide base polyps, 15 cases with sub-pedicle polyps and 5 cases with pedicle polyps. The pathologic examination showed 17 cases with pure serrated adenoma, 33 cases with serrated adenoma complicated with low grade intraepithelial neoplasia, 1 case with serrated adenoma complicated with high grade intraepithelial neoplasia and 1 case with local malignant of serrated adenoma. Conclusions: The clinical symptoms of serrated adenoma are non-specificity, the single and wide base polyps complicated with intraepithelial neoplasia are most, located in rectum.
