The knowledge level for EUS indications among gastroenterologists across different locations and practices is not known. The aim of this study was to assess knowledge of EUS indications among a diverse group of gastroenterologists, both nationally and internationally.
A web-based survey was designed to assess knowledge of EUS with respect to 4 organ systems: esophagus, gastroduodenum, hepatopancreatobiliary, and colorectum. The survey was distributed by electronic mail (e-mail) to members of the American Society for Gastrointestinal Endoscopy.
The survey was distributed to 3848 physicians, of whom 2848 had an active e-mail address. There were 323 respondents (11.3%), of whom 210 were U.S. members and 113 international. Overall, the mean score for the different organ systems for all respondents was highest for gastroduodenum (93% correct) and lowest for colorectum (71%) compared with esophagus (79%) and hepatopancreatobiliary (83%) systems. The mean total score was higher for U.S. respondents (84% correct) compared with international respondents (79%, p < 0.0001). Endosonographers fared better than those who were not endosonographers (85% vs. 81%, p = 0.0002).
Knowledge levels of colorectal applications of EUS are poorest among the 4 organ systems studied. Future educational initiatives should focus on applications of EUS in this category. Studies are required to assess the impact of this education on the appropriateness of EUS referral patterns.
不同地区和执业情况的胃肠病学家对超声内镜检查（EUS）适应证的了解程度尚不清楚。本研究的目的是评估国内外不同群体胃肠病学家对EUS适应证的了解情况。
设计了一项基于网络的调查，以评估EUS在4个器官系统（食管、胃十二指肠、肝胰胆和结直肠）方面的知识。该调查通过电子邮件分发给美国胃肠内镜学会的成员。
该调查共发送给3848名医生，其中2848名有有效的电子邮件地址。共有323名受访者（11.3%），其中210名是美国成员，113名是国际成员。总体而言，所有受访者在不同器官系统方面的平均得分，胃十二指肠最高（正确率93%），结直肠最低（71%），食管（79%）和肝胰胆系统（83%）居中。美国受访者的平均总分（正确率84%）高于国际受访者（79%，p<0.0001）。超声内镜检查医生的表现优于非超声内镜检查医生（85%对81%，p=0.0002）。
在所研究的4个器官系统中，EUS在结直肠方面的应用知识水平最差。未来的教育倡议应侧重于EUS在这方面的应用。需要开展研究来评估这种教育对EUS转诊模式合理性的影响。
