接触法经内镜氩离子凝固术治疗隆起糜烂性胃炎的研究

目的 研究接触法经内镜氩离子凝固术（APC）治疗隆起糜烂性胃炎的疗效、效率及安全性。方法 63例隆起糜烂性胃炎患者随机分成A组（非接触法APC治疗纽）和B组（接触法APC治疗组）；比较两种方法的疗效、效率和安全性。结果 虽然A、B两组在疗效（治愈率：A组：96．8％；B组：96．9％；P〉0．05）和并发症（A、B两组各有3例术后1～3d出现轻微上腹隐痛或腹胀，3～7d后自行消失。均无出血、穿孔等严重并发症发生）上无明显差异，但效率和误伤的差异却极为显著（P〈0．01）；A组无效操作、治疗用时及误伤次数分别为284次，11min38s和137次，而B组分别为96次，7min22s和58次。结论 接触法经内镜APC治疗隆起糜烂性胃炎不仅具有非接触法APC疗效显著，安全性好等优点，而且较非接触法APC操作更加方便，误伤大大减少，效率明显提高。

Study on Contact Endoscopic Argon Plasma Coagulation for the Treatment of Protuberant Erosive Gastritis

Objective To evaluate the efficacy and safety of contact endoscopic argon plasma coagulation(APC) for treating protuberant erosive gastritis. Methods 63 patients with protuberant erosive gastritis were randomly divided into groups A and group B, which were treated with non-contact and contact APC, respectively. The efficacy and safety were compared between the two groups. Results There was no significant difference between group A and group B in the efficacy and complication frequency. The curative rates in group A and B were 96.8% and 96.9%, respectively, and only 3 patients had abdominal pain or distension 1 to 3 days after operation, and disappeared within 3 to 7 days after treatment in each group. The numbers of ineffective operation in groups A and B were 284 and 96, respectively. The duration of operation in groups A and B was 11 min and 38 sec,7 min and 22 sec, respectivley. The numbers of accidental injury in group A and B were 137 and 58 times, respectively (all P<0.01). There were significant differences in the number of ineffective operation, the duration of operation and the number of accidental injury between the two groups. Conclusion Contact endoscopic APC for treating protuberant erosive gastritis not only had same efficacy and safety as non-contact APC, but also was more simple and convenient, less accidental injury and more efficient than non-contact endoscopic APC.
