摘要
本院9年间2389例纤维结肠镜检查中,共检出下消化道息肉561例,计大肠息肉1256个,末段回肠息肉82个;共摘除息肉1299个,均用活检钳咬切。经病理证实腺瘤406个,其中有异型性增生者89个,恶变者23个;在932个非肿瘤性息肉中,有异型性增生102个。脉瘤属癌前病变,经纤维结肠镜摘除大肠息肉,特别是有异型性增生者,可使大肠癌发病率下降。本组肠癌合井息肉者达51.28%,肠癌术后亦可能再发息肉。及早发现恶变的小腺瘤是提高大肠癌疗效的关键。
The results of 2389 patients examined by colonofiberscope in past nine years are reported. Polyps were found in 561 cases, including 1256 polyps in the large intestine and 82 polyps in the terminal ileum. All 1299 polyps were removed with biopsy forceps. Pathology demonstrated that there were406 adenomas, including 89 atypical hyperplasia and 23 cases with malignant change and 932 non-cancerous polyps with 102 atypical hyperplasia. Since adenoma is seen to be a precancerous change, thepolypectomy by colonofiberscope, especially atypical hyperplastit polyps may decrease morbidity of largeintestinal cancer. Cancer associated with adenoma may be as high as 51. 28%, so the recrudescence ofpolyps may possibly be found even after the cancer removal. These data showed that an early discoveryof small malignant adenoma is key to improve efficiency.
