目的 探讨氩离子血浆凝固术（ＡＰＣ）对胃肠广基扁平息肉和出血的治疗作用。方法 广基扁平息肉患者１３例，３１枚息肉，行内镜下ＡＰＣ治疗；大息肉内镜切除及活检后出血５例，ＡＰＣ术止血治疗；对照组广基扁平息肉息者２０例，２８枚息肉，行内镜下热凝电极治疗。结果ＡＰＣ术和热凝电极在广基扁平息肉治疗中疗效相同，局部疼痛的副作用相似，但ＡＰＣ术导管探头无粘连，明显优于热凝电极治疗组５５％的发生串（Ｐ＜０．０１）。ＡＰＣ治疗大息肉内镜切除及活检后渗血迅速有效。结论ＡＰＣ术治疗胃肠广基扁平息肉及出血简便有效。
Objective To investigate the therapeutic effect of argon plasma coagulation (APC) on gastrointestinal flat polyps and hemorrhage. Methods Thirteen patients with polypoid flat polyp were treated with endoscopic APC. Large polyp endoscopic resection and post-biopsy hemorrhage were performed in 5 cases and APC operation was performed in 20 cases. Polyps, endoscopic thermocoagulation electrode therapy. Results APC and thermocoagulation electrodes showed the same effect in the treatment of flat-base polyps, but the side effects of local pain were similar. However, the APC catheter probe had no adhesions, which was significantly better than 55% in the thermocoagulation electrode group (P <0.01) ). APC treatment of large polyps endoscopic resection and biopsy quickly and effectively bleeding. Conclusions APC is simple and effective in treating gastrointestinal flattened polyps and bleeding.
