Endoscopic high-frequency soft coagulation, recently developed in Japan, is available for the management of gastric bleeding in cases of bleeding gastric ulcers and bleeding during endoscopic submucosal dissection. The aim of this study was to evaluate the efficacy of hemostasis with soft coagulation for bleeding gastric ulcers by comparing it with hemoclips in a prospective, randomized trial.
During the period of April 2006 to March 2008, 96 patients that had gastric ulcers with bleeding or nonbleeding visible vessels were enrolled in this study. All of the 96 patients were randomly divided into two groups: endoscopic hemostasis with soft coagulation (Group I) or endoscopic hemoclipping (Group II).
A total of 41 (85%) out of 48 patients in Group I and 38 (79%) out of 48 patients in Group II were successfully treated with soft coagulation or clipping alone, respectively. The endoscopic hemostasis rate for the initial modality in combination with another endoscopic procedure performed after the initial method was 98% in both groups. One patient in Group I (2%) and five patients in Group II (10%) experienced recurrent bleeding. The time required to achieve hemostasis was shorter in Group I compared with Group II (9.2 +/- 11.1 vs. 13.6 +/- 9.4 min; P < 0.05).
This study revealed that soft coagulation is as effective as hemoclipping for treating bleeding gastric ulcers. The time required to achieve hemostasis was shorter with the soft coagulation procedure.
内镜高频电凝软切除术是日本最近开发的一种技术,可用于治疗出血性胃溃疡和内镜黏膜下剥离术中的出血。本研究旨在通过前瞻性随机试验比较软凝止血与止血夹治疗出血性胃溃疡的疗效。
2006 年 4 月至 2008 年 3 月期间,共有 96 例有出血或无出血可见血管的胃溃疡患者入组本研究。所有 96 例患者均随机分为两组:内镜软凝止血(I 组)或内镜止血夹(II 组)。
I 组 48 例患者中,共有 41 例(85%)患者和 II 组 48 例患者中,共有 38 例(79%)患者分别单独采用软凝或夹闭成功止血。两组初始治疗方法联合后续内镜治疗的止血率均为 98%。I 组 1 例(2%)患者和 II 组 5 例(10%)患者出现再出血。I 组达到止血所需的时间明显短于 II 组(9.2 ± 11.1 比 13.6 ± 9.4 分钟;P < 0.05)。
本研究表明,软凝止血与止血夹治疗出血性胃溃疡同样有效。软凝止血所需的时间更短。
