【摘要】
目的 探讨结肠息肉高频电凝切除术后延迟性出血的原因及处理措施。方法分析结肠息肉患者高频电凝切除术后延迟性出血的临床资料。结果 756例结肠息肉经高频电凝切除术后发生延迟性出血15例;病变部位结肠息肉的直径在0.5～3.0cm之间;出血时间为48h～5d;小量出血8例，中量出血4例，大量出血3例，无1例死亡。结论 为了避免延迟性出血的发生，应注意术前、术中和术后3个环节，出血后应及时处理。

利用高频电摘除消化道息肉随着临床不断推广应用和手术器械及操作方法的改进，目前已成为可取代手术的治疗方法。但术后出血并发症影响治疗效果，特别是延迟出血容易误诊，应引起医患人员的高度重视。我院消化内科1995年5月成功开展了经内镜高频电凝摘除结肠息肉术，至今已治疗756例病人。现总结报告如下。
