Abstract：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.
