Objective To compare the efficiency and safety of using the homemade water sac with conventional affusion methods of endoscopic miniprobe ultrasonography. Methods The esophageal lesions and fundus of stomach lesions were divided into two groups,each group conducted endoscopic miniprobe ultrasonography with homemade water sac and conventional affusion respectively. There were 160 cases in all,and they were divided into 4 groups, with 40 cases in each group. Results Compared with using conventional affusion,using homemade water sac made the operating time shorter and the lesions image more clearly, whether in esophageal lesions or fundus of stomach lesions. Moreover, the accuracy rate of diagnosis was increased by 10% ,the complication rate was reduced by 5%. Conclusion Homemade water sac play a significant role in endoscopic miniprobe ultrasonography for its efficient, practical, economic and security.%目的 对比分析自制水囊和常规注水两种方式在超声小探头内镜检查中的安全性和检查效果.方法 按照食管病变(80例)和胃底病变(80例),分别用自制水囊和常规注水两种方式行超声小探头检查,进行相同病变部位的组内比较.结果 在食管病变和胃底病变中,自制水囊超声小探头检查相比常规注水超声小探头检查操作时间明显缩短(P<0.05),病变图像更清晰,使诊断准确率分别提高约10%(P＞0.05),且并发症发生率相比减少约5%(P＞0.05).结论 自制的水囊在超声小探头检查中起到了高效且相对安全的作用.
