我院在600例结直肠癌中,有同时多原发癌47例(7.83%),异时多原发癌20例(3.33%)。同时癌多数分布集中,但分散者亦不少。近年来有增加的趋势。多原癌伴息肉者31例(46.29%),其中17例癌变(12.23%),异时癌中残留息肉恶变成癌2例。同时多原癌的另一病变可能比较早,体积相对较小,是同时癌在首次治疗中易忽略的重要原因。本文作者充分利用纤结镜作术前术后检查,术中注意仔细探查,是提高本病的发现率的重要原因。处理主张首次手术应彻底切除癌与癌前病变,以扩大肠段根治与分段根治切除为主,并讨论了结肠次全切除的指征与效果。本病治疗效果较好。
In 600 cases of colorectal cancer in our hospital, there were 47 cases (7.83%) with multiple primary cancers, and 20 cases (3.33%) with multiple primary cancers. At the same time, the majority of cancers are concentrated, but there are also many scattered people. In recent years there has been an increasing trend. There were 31 cases (46.29%) with multiple cancers and polyps, of which 17 cases were cancerous (12.23%). There were 2 malignant cancers with polyps in different time. At the same time, another lesion of multiple cancer may be relatively early, and the volume is relatively small, which is an important reason why cancer is easily overlooked in the first treatment. The author of this article made full use of fibroscopes for preoperative and postoperative examinations, careful attention to intraoperative exploration, is an important reason to improve the discovery rate of the disease. Treatment advocates that the first operation should be completely resection of cancer and precancerous lesions, to expand the bowel radical resection and radical radical resection, and discuss the indications and effects of subtotal colectomy. The disease treatment effect is better.
