目的 :评价单环密集套扎法治疗食管静脉曲张出血效果 ,并对该操作方法中的一些具体问题进行讨论。方法 :47例门脉高压食管静脉曲张出血患者 ,进行内镜下择期套扎治疗 ,全部病例采用国产或丹麦产单环套扎器。前期的 2 2例接受标准套扎法治疗 ,每次套扎 4个橡皮圈。后期的 2 5例接受密集套扎法 ,每次套扎 10个～ 15个橡皮圈。结果 :标准套扎组平均每例套扎 3.3次 ,平均每例共套扎 13.5个圈。密集套扎组平均每例套扎 1.3次 ,平均每例套扎 11.4个圈。静脉曲张消失率标准组为 72 .7% ,密集组 96 % ,静脉曲张消除的平均天数标准组为 38.2 d,密集组为 19.2 d。结论 :单环密集套扎法疗效优于标准套扎法 ,适合目前国情 ,在食管静脉曲张单环套扎 (EVL )中仍占有重要地位。
OBJECTIVE: To evaluate the effect of single-loop intensive ligation on esophageal varices bleeding and to discuss some of the specific problems in this procedure. Methods: 47 cases of portal hypertension patients with esophageal varices were treated with endoscopic ligation, all cases were made by domestic or Danish single ligation. In the early stage, 22 patients underwent standard ligation and four rubber bands per ligation. The latter 25 cases received intensive ligation, each ligation 10 ~ 15 rubber bands. Results: The standard ligation group averaged 3.3 times per case ligation, an average of 13.5 laps a total of ligation. Intensive ligation group an average of 1.3 ligatures per case, an average of 11.4 laps per case. The disappearance rate of varicose veins was 72.7% in the standard group and 96% in the intensive group. The average number of days of varicose veins disappeared was 38.2 days in the standard group and 19.2 days in the intensive group. Conclusion: The single-loop intensive ligation method is superior to the standard ligation method, which is suitable for the current national conditions and still occupies an important position in the single-loop esophageal varices ligation (EVL).
