结肠黑变病的临床特点分析

Analysis of clinical characteristics of melanosis coli

摘要:

目的 分析结肠黑变病（MC）的检出率及其与性别、伴发肠道疾病的相关性。方法 回顾性分析2013年1月－2020年10月该院378例行电子结肠镜检查并诊断为MC的患者的内镜资料及相关临床资料。采用SPSS 20.0统计软件分析MC的检出率及其与年龄、性别、伴发肠道疾病的相关性。结果 MC的检出率呈逐年升高趋势。年龄 ≤ 60岁的患者中，女性检出率高于男性；大于60岁且小于80岁的患者中，男性检出率及上升幅度大于女性。息肉是MC最常见的伴发疾病，约占28.31%。息肉大小和性别差异无统计学意义。结论 MC呈逐年上升趋势。80岁前，其检出率随着年龄的增长而增加。MC与结肠息肉、结肠癌关系密切，可合并炎症性肠病、结肠憩室、结直肠炎和脂肪瘤等。

Abstract:

Objective To analyze the the detection rate of melanosis coli (MC) and its correlation with gender, intestinal diseases.Methods Endoscopic data and relevant clinical data of 378 patients diagnosed with MC who underwent colonoscopy from January 2013 to October 2020 were retrospectively analyzed. SPSS 20.0 statistical software was used to analyze the detection rate of melanosis coli and its correlation with age, gender and concomitant intestinal diseases.Results The detection rate increased year by year. The detection rate of MC in women was higher than that in men when they were under 60 years old. The detection rate and increase range of MC in men were higher than that in women when they were under 60 and 80 years old. Polyp is the most common concomitant disease of MC, accounting for about 28.31%. There was no significant difference in polyp size and gender.Conclusion MC is increasing year by year. Before the age of 80, the detection rate increased with age. MC is closely related to colonic polyps and colon cancer. It can also be associated with inflammatory bowel disease, colonic diverticulum, colorectal inflammation, lipoma and so on.
