水囊辅助环扫超声内镜对食管黏膜下肿物的诊断价值

Diagnostic value of water sac-assisted radial scanning endoscopic ultrasound for esophageal submucosal tumors

目的比较水囊法和水充盈法在食管黏膜下肿物(SMT)的超声内镜(EUS)检查中的优劣,评估水囊法对提高超声内镜诊断食管SMT的效率、准确性及安全性。方法将某院行超声内镜检查食管SMT患者110例,随机分为水囊法组和水充盈法组,每组55例。分别记录两组患者超声内镜检查操作时间、病变环扫EUS图像清晰度、彩色多普勒(CDFI)图像清晰度、并发症发生率、操作医生满意度和患者耐受度。结果水囊法操作时间短于水充盈法,EUS与CDFI图像清晰度及操作医生满意度、患者耐受度方面均优于水囊法(均P<0.01),两组并发症发生率差异无统计学意义(P>0.05)。结论水囊法在超声内镜诊断食管SMT中较传统水充盈法效率更高、图像质量更好、患者耐受度更高,值得临床推广。

Objective To compare the advantages and disadvantages of water sac method and water filling method in endoscopic ultrasound(EUS)for esophageal submucosal tumors(SMT)and evaluate the role of water sac method in improving the efficiency,accuracy and safety of EUS in the diagnosis of esophageal SMT.Methods A total of 110 patients with SMT who underwent endoscopic ultrasonography were randomly divided into Water-Sac Group and Water-Filling Group,55 cases in each group.The operation duration of endoscopic ultrasonography,image resolution of EUS,image resolution of color Doppler flow imaging(CDFI),the incidence of complications,the satisfaction of doctors and the tolerance of patients were documented for the two groups.Results The operation duration of water-sac method was shorter than that of water-filling method.The resolution of EUS and CDFI images,the satisfaction of operating doctors and the tolerance of patients of water-sac method were better than those of water-filling method(P<0.01).There was no significant difference in the incidence of complications between the two groups(P>0.05).Conclusion Water sac method is more efficient,has a better image quality and is more tolerant for patients in the diagnosis of esophageal SMT by EUS compared with water filling method,which is worth clinical promotion.
