门诊患者大肠镜检查的临床意义

目的探讨对有症状就诊人群进行大肠镜检查的临床意义。方法１９９５年～１９９６年对１２４６例因有下消化道症状就诊于消化科的患者进行大肠镜检查。结果肠粘膜炎性改变４３７例，溃疡性结肠炎５５例，息肉１８７例（腺瘤１２１例，增生性息肉６６例），肠癌１１１例，未发现病变４１１例。在１８７例中发现并摘除息肉２９１枚，其中１３例１３枚息肉有局部恶变者电凝摘除后随访１年无异常发现。１１１例肠癌中ＤｕｃｋＡ６０例。腺癌、息肉的检出率与年龄呈正相关（Ｐ＜０．０５），但≤２９岁组腺癌、息肉也分别检出１．８％和１６．４％。结论有症状就诊人群大肠镜检查是一可行、安全、费用不高和省时的方法，能明显减少大肠癌的发病率和死亡率。
