目的 探讨老年大肠复合性息肉患者的临床特点及其与癌变的关系。方法 对 336例老年大肠息肉患者结肠镜检查发现复合性息肉 86例 ,分别活检。结果 复合性息肉发生率为 2 5 .5 9%,随年龄增长检出率增加 ;多累及 2个以上的肠段 ;分布多见于直肠、乙状结肠 ;以炎性息肉和腺瘤性息肉并存多见。腺瘤发生率为4 6 .0 7%,高于单发性及多发性息肉 ,有显著性差异 (P <0 .0 1)。复合性息肉的癌变率为 12 .79%,与单发及多发性息肉比较无显著性差异。结论 对老年复合性息肉要重视 ,对多发息肉要分别做病理检查 ,提高诊断率。
Objective To investigate the clinical characteristics of elderly patients with large intestine polyp and its relationship with carcinogenesis. Methods A total of 86 cases of complex polyps were examined by colonoscopy in 336 cases of elderly patients with colorectal polyps and were biopsied. Results The incidence of polyps was 25.59%. The detection rate increased with age. More than two intestinal segments were involved. The distribution was more common in the rectum and sigmoid colon. With the coexistence of inflammatory polyps and adenomatous polyps . The incidence of adenoma was 46.70%, higher than that of single and multiple polyps, there was a significant difference (P <0.01). The canceration rate of complex polyps was 12.79%, with no significant difference compared with single and multiple polyps. Conclusions The polyp of the elderly should pay attention to multiple polyps should be done separately pathological examination to improve the diagnostic rate.
