PTU-019 Nasal or standard endoscopy (nose) for diagnosis of Barrett's oesophagus – efficacy and patient tolerance: Abstract PTU-019

2010 
Introduction In order to detect all cases of Barrett9s oesophagus (BE) in the population, with the aim of reducing adenocarcinoma associated mortality, screening needs to be considered. Unsedated transnasal endoscopy (TNE) can potentially offer a safer and less expensive alternative to conventional sedated endoscopy (CE) for detecting BE. Aims (1) To evaluate the sensitivity and specificity of TNE in diagnosing BE compared with CE. (2) To assess patient acceptability of TNE for a future multicentre screening trial. Methods Patients with known BE under surveillance and those referred for routine endoscopy for other reasons underwent both TNE and CE in a randomised cross-over design. TNE findings of endoscopic BE, biopsy size and presence of intestinal metaplasia (IM) were compared against CE, which was used as gold standard. Pre and post endoscopy short-form spielberger state-trait questionnaires (SF6), a visual analogue scale and a single question addressing preference for endoscopy type were used to measure patient acceptability of the procedures. Results Of 57 patients randomised, 50 completed the study. All 22 BE cases with columnar lined epithelium (CLE) on CE were correctly diagnosed by TNE. Although the biopsy size of TNE was significantly smaller compared to CE (mean size 2.59 vs 4.74 p Conclusion TNE is accurate in diagnosing BE and detecting IM. Despite the smaller biopsy size, it detected an equal number of IM cases and showed potential to detect dysplasia. It was well tolerated and preferred by patients and may be an efficient screening method for BE.
