老年大肠复合性息肉临床研究

Clinical Study of Large Intestine Complex Polyps in the Elderly

目的提高对老年大肠复合性息肉的认识。方法在２２１例老年大肠息肉患者中发现复合性息肉２６例，观察复合性息肉的临床病理特点。结果老年大肠复合性息肉并非少见，检出率为１１．８％，多位于直、乙状结肠，占３８．７％，以炎性息肉和腺瘤并存者居多，占８９％，恶变率２６．９％，多肠段息肉检出复合性息肉率高，为２１．３％（Ｐ＜０．０５）；年龄以７０～７９岁检出率最高，为２６．３％（Ｐ＜０．０５）；其检出率与数目、性别无关（Ｐ＞０．０５）。结论要重视老年复合性息肉，对多发性息肉要尽可能做多个息肉病理检查，提高其诊断率。

Objective To improve the understanding of large intestine complex polyps in the elderly. Methods 26 cases of complex polyps were found out in 221 cases of large intestne polyps in the elderly. Their clinical pathological features were analyzed.Results Complex polyps in the elderly are not rare.The detectable rate was 11 .8% in the study.They were located inchly in the rectum and the sigmoid (38 .7% ). The most common hist ologic type of polyp was inflammatory polyp coexicting with adenomas (89% ). The ma lignant rate was 26.9% .The detectable rate of complex polyp was the highest in the multicle Sections of colon(21. 3%, P < 0.05) and in the age from 70 to 79 (26. 3%, P < 0.05). There was no difference in quantity and sex(P < 0.05). Conclusions More attention should be paid to complex polyps in the elderly. It is necessary biopsy all the polyps in the multicle polyps so as to highten the clinical diagnostic rate.
