Abstract
Introduction: Demand for endoscopic services is outstripping capacity in the UK. Transnasal endoscopy (TNE) utilises a narrow calibre endoscope to pass through the nasal passages, thereby reducing retching and discomfort. It is better tolerated compared with standard transoral endoscopy (TOE) but is still rarely used as a diagnostic modality. There is still uncertainty about how well it performs against TOE in diagnostic ability, cost and efficiency. Methods: We explored utilising TNE to deal with the growing demand for endoscopy. We compared findings to TOE procedures undertaken during the same time period. We evaluated cost differences, duration/time in the department for procedures as well as quality of procedures (both in terms of performance indicators as well as image quality using the validated POLPREP score). Results: A total of 241 upper gastrointestinal endoscopy procedures were evaluated (100 TNE and 141 matched TOE) between December 2021 and February 2022. TNE outperformed TOE in obtaining >95% success rate in nationally approved key performance indicators (retroflexion and duodenal intubation, both p=0.026). It also was associated with better image quality in the oesophagus with a POLPREP A3 Score (excellent image quality) in 36/98 available images compared with 26/136 TOE (p=0.028) and was equivalent to TOE in the stomach and duodenum. TNE was identified as having a key role in facilitating complex cases, previously failed via the TOE route with a success rate in 11/12 (91.7%) of such cases. TNE also shows promise in correcting misdiagnoses of short-segment Barrett's oesophagus (39%) compared with TOE (14.8%) (p=0.087). Conclusion: TNE is an emerging endoscopic modality, which shows great promise in replacing TOE in most diagnostic circumstances. In a modern healthcare service, TNE is cheaper, better tolerated and outperforms TOE in multiple domains.
