摘要
本文回顾性调查了：（１）大肠远侧腺瘤是否标志着同存大肠近侧息肉以及危险性；（２）随年龄增加是否有大肠腺瘤从左侧向右侧分布的右移倾向。结果：大肠镜检查并且病理诊断确切者３７４例，分成腺瘤２９７例，炎性息肉７７例。大肠远侧腺瘤的２６２例中，有６９例（２６．３％）同存大肠近侧腺瘤，大肠远侧炎性息肉的７０例中只有５例同存大肠近侧腺瘤（７．０％），二者相比有显著性差异（Ｐ＜０．０１）。故与炎性息肉相比，大肠远侧有腺瘤者同存大肠近侧腺瘤的危险性高６．４倍（９５％可信限２．５～１４．８）。脾曲以上有大肠腺瘤者（１０９例）与脾曲以上无腺瘤者（１９３例）相比，平均年龄大７岁（５７．８±１２．２比５１．７±１６．２，Ｐ＜０．０１），说明随年龄增加大肠腺瘤有右移倾向。
A retrospective investigation was made to know whether: ①distal colonic adenomas marked for synchronous proximal adenoma in the colon;②the increasing age was associated with a left to shift of colonic adenomas.Three hundred seventy four patients with colorectal polyps diagnosed by colonoscopy and histology were evaluated .Of 262 patients with distal colonic adenomas synchronized proximal colonic adenoms (26.4%), While in 70 patients with distal colonic hyperplastic polyps proximal colonic adenoms were diagnosed in 5 pattients(7.0%). Patients with distal adenomas were nearly 6 times as likely to have proximal adenomas as patients with distal hyperplastic polyps(odds ratio 6.5, 95% confidence interval 2.5 ￣14.8). The average age in patients with adenomas proximal to splenic flexure was 7 years oldy with distal cplonic adenomas (57.8±12.2 verse 51.7±16.2, P<0.01), which suggested a left to right shift tendcncy of colonic adenoma associated with the increasing age.
