摘要
目的:探讨内镜下氩离子凝固术,介入治疗胃肠道息肉的应用价值及疗效.方法:采用德国ERBE公司生产的APC300型内镜专用氩气刀,对经病理学证实为胃肠道息肉进行氩离子凝固术,氩离子凝固治疗以内镜下整个病灶凝固为止,每枚息肉根据其部位、大小决定氩离子凝固次数.结果:采集446例患者共659枚息肉,其中508枚为直径小于5 mm的扁平、广基息肉.经内镜氩离子凝固术治疗,3mo内复查内镜病变全部消除,治愈率为100%;直径大于5mm广基或亚蒂、细蒂息肉136例,118例经1次氩离子凝固术治疗,3 mo后复查内镜病变全部消除.18例经第2次氩离子凝固术治疗,3mo后再次复查内镜病变消除;另有15枚有蒂息肉,在内镜圈套高频电刀治疗同时,采用内镜下氩离子凝固术配合治疗,3 mo后再次复查内镜病变全部治愈.结论:内镜下氩离子凝固术对胃肠道广基、扁平息肉或息肉样隆起治愈率高、疗效显著,且简便易行、并发症少,有较高的临床应用价值.
Abstract
AIM: To evaluate the values and therapeutic effects of endoscopic argon plasma coagulation (APC) in the treatment of gastrointestinal (GI) polyps. METHODS: GI polyps confirmed pathologically were coagulated by argon plasma generated by German-made ERBE APC 300 EA. The number of times of coagulation for each polyp was determined by its size and location. RESULTS : A total of 659 polyps in 446 cases were investigated. Five hundred and eight flat and thin (diameter <5 mm) sessile polyps were totally removed by APC (100% ). Among the 136 sessile polyps with diameter > 5 mm, 118 cases were removed by one-time APC and 18 flat polyps were removed by two-time APC. Fifteen pedunculated polyps were removed by combination of APC and high frequency electron surgical unit. CONCLUSION: APC is safe and effective in the treatment of GI polyps, especially in the treatment of flat and thin sessile gastrointestinal polyps.
