大多数结肠癌系由良性结肠息肉演变,而且大多数结肠息肉能经结肠镜切除,因此人们对哪些恶性结肠息肉能经结肠镜切除,而对哪些则需手术切除便产生了极大兴趣。本文报道作者8年间所见的80例恶性结肠息肉。 80例患者共有恶性结肠息肉83个,49个(59%)有蒂,34个(41%)无蒂;72%位于乙状结肠,77%的大小为1～3 cm;按组织学分型,管状腺瘤并浸润癌28个,息肉样癌25个,绒毛状腺瘤并浸润癌17个,管状绒毛状腺瘤并浸润癌13个。
Most colon cancers evolve from benign colonic polyps, and most colon polyps can be resected by colonoscopy. Therefore, which malignant colon polyps can be removed by colonoscopy and which ones require surgical resection have great interest. This article reports 80 cases of malignant colon polyps seen by the author in 8 years. Eighty-eight patients had 83 malignant colon polyps, 49 (59%) had pedicles, and 34 (41%) had no pedicles; 72% were located in the sigmoid colon and 77% had a size of 1 to 3 cm; according to histological type, tubular glands Tumors were infiltrated with 28 carcinomas, 25 polypoid carcinomas, 17 villous adenomas with invasive carcinoma, and tubular villous adenomas with 13 invasive carcinomas.
