*Two hundred twenty-five procedures were performed of which 209 patients had a completed TNE in which the clinical intention was achieved.

†Of these 16 incomplete procedures, a further 5 patients for whom the nasal route was unsuccessful were successfully converted to the oral route; there were also 3 patients who also did not tolerate the oral route either.

‡Of the 16 incomplete procedures, 2 patients had examinations of the oesophagus and stomach in retroflexion before withdrawing consent, giving a figure of 211.

§Four of these patients scoped for Barrett’s or EoE surveillance did not have D2 intubation as they had recent completed examinations.

EoE, eosinophilic oesophagitis; TNE, transnasal endoscopy.
