title: Transnasal OGD: practice survey and impact of a live video retransmission.
abstract: BACKGROUND
  Unsedated transnasal oesogastroduodenoscopy significantly improves patient tolerance compared to unsedated conventional peroral oesogastroduodenoscopy.
  
  
  OBJECTIVE
  To assess the adoption of transnasal oesogastroduodenoscopy among endoscopists from various European countries and its determinants.
  
  
  METHODS
  A survey was distributed to 624 endoscopists attending a live course on digestive endoscopy; a poll was also performed immediately before and after live video retransmission of a transnasal oesogastroduodenoscopy.
  
  
  RESULTS
  Answer rate was 48%; transnasal oesogastroduodenoscopy was practised by 31% of respondents. In multivariate analysis, practice of transnasal oesogastroduodenoscopy was associated with location in France and Netherlands (P<0.0001), availability of many gastroscopes (P<0.0001) and less frequent use of sedation (P=0.006). Endoscopists who did not practise transnasal oesogastroduodenoscopy cited doubts about its advantages over conventional oesogastroduodenoscopy and lack of training (34% each) as barriers to adoption. Seventy-four percent of endoscopists practicing transnasal oesogastroduodenoscopy did actually use it in <20% of eligible cases. Live video retransmission of a transnasal oesogastroduodenoscopy increased the proportion of endoscopists interested in this technique (P=0.006).
  
  
  CONCLUSIONS
  Adoption of transnasal oesogastroduodenoscopy largely varies between European countries; endoscopists practicing this technique use it in a minority of eligible cases. Live case demonstration may decrease barriers to the adoption of this technique.
