title: Clinical findings confirm national guidelines regarding primary gastroscopy for upper gastrointestinal symptoms.
abstract: BACKGROUND
  This study describes unsedated transnasal oesophagogastroduodenoscopy (UT-OGD) in the office setting. Evaluation of national guidelines regarding primary endoscopy for the investigation of upper gastrointestinal (GI) symptoms was also a focus of this study.
  
  
  METHODS
  Retrospective registration of 2,000 cases regarding demographics, symptoms, pre-endoscopic treatment, feasibility and findings.
  
  
  RESULTS
  The proportion of males was 42%. 19% of the patients were referred due to alarm symptoms. The transnasal feasibility was 97%. Endoscopic findings: No abnormal findings (NAF) 53%, hiatal hernia 25%, oesophagitis 11%, gastric inflammation 11%, ulcer 10%, cancer 1% and others 1%. Alarm symptoms (AS) versus non-alarm symptoms (NAS): 35% of patients with AS had NAF versus 58% in the NAS group (p < 0.001). Cancer was present in 4% of the cases in the AS group versus 0.1% in the NAS group (p < 0.001). < 45 years versus ≥ 45 years: 69% of patients < 45 years had NAF versus 45% of patients ≥ 45 years (p < 0.001). Cancer was present in 0% of the cases in those < 45 years versus 1.4% in those ≥ 45 years (p = 0.002).
  
  
  CONCLUSIONS
  UT-OGD in private practice had a higher proportion of females than similar procedures performed in hospital settings. Feasibility was high. Endoscopic findings were comparable to those reported by other studies, except for a lower prevalence of oesophagitis. Age < 45 years and absence of alarm symptoms were strong negative predictors for the presence upper GI cancer. Our data thus seem to confirm the Danish guideline regarding primary endoscopy for the investigation of upper GI symptoms.
