Purpose: The knowledge level for endoscopic ultrasound (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.

Methods: A web-based survey was designed to assess knowledge of EUS with respect to four organ systems: esophagus, gastroduodenum, hepato-pancreato-biliary, and colorectum. The survey was distributed by electronic mail (e-mail) to members of the American Society for Gastrointestinal Endoscopy.

Results: The survey was distributed to 2848 physicians who had an active e-mail address. There were 323 respondents (11.3%) of whom 210 were US members and 113 international. Overall, the mean score for the different anatomical regions for all respondents was highest for gastroduodenum (93% correct) and lowest for colorectum (71%) compared to esophagus (79%) and hepato-pancreato-biliary (83%) categories, p < 0.0001. The mean total score was higher for US respondents (84% correct) compared to International respondents (79%), p < 0.0001 (Figure 1). Endosonographers fared better than non- endosonographers (85% vs. 81%), p = 0.0002 (Figure 2).

Conclusions: Knowledge of colorectal applications of EUS is poorest. While future educational initiatives should focus on all applications of EUS, particular emphasis appears necessary in this category. Studies are required to assess the impact of this education on the appropriateness of EUS referral patterns.[figure 1][figure 2]
