572例大肠息肉内镜治疗的临床分析

目的 探讨大肠息肉的临床表现、内镜治疗、病理结果、息肉与癌的关系和随访情况。方法 对内镜检出的大肠息肉患者的临床表现、内镜治疗、病理资料、随访结果进行分析。结果 大肠息肉的检出率为１２．７３％，其中腺瘤性息肉占５３．９２％。主要临床表现为便血，息肉的分布主要在左半结肠。非腺瘤性息肉未发现癌变，腺瘤性息肉的瘤理类型和大小与重度不典型增生、癌变有密切关系。随访观察大肠息肉有较高的复发率和再发率（６．００％和１８．００％）。结论 高频电凝切除息肉是有效的治疗方法。息肉绒毛成分多、体积大易发生重度不典型增生和癌变。定期随访对于预防息肉恶变、降低癌发生率、提高大肠癌患者的生存率具有重要意义。
