Background As with isolated ileitis the findings of nonspecific small bowel enteritis (NSE) on capsule endoscopy (CE) poses a clinical challenge. There is lack of available evidence to help clinicians to predict significant disease and long-term prognosis. Aim To define the natural history of NSE in an Irish cohort. Methods Patients with a finding of NSE were identified from a database. Subsequent investigations, treatments and diagnosis were recorded. Patients were grouped based on ultimate diagnosis: Crohn’s disease (CD), Irritable bowel syndrome (IBS), NSAIDs enteritis (NSAIDs), persistent NSE and no significant disease (NAD). Results 88 patients, 46 (52%) male, mean age 52 ± 17.8 years were included with a mean follow up of 23 ± months. The ultimate diagnoses were NAD = 43 (49%), CD = 17 (19%), IBS = 14 (16%), NSAIDs = 12 (14%) and persistent NSE = 2 (2%). Significantly, more patients diagnosed with CD on follow up were referred with suspected CD. CD = 14/17 (82%) vs 13/57 (23%), p < 0.001. While a diagnosis of CD was associated with a positive baseline Lewis score (> 135); 11/17 (65%) CD versus 16/ 71 (23%). Female gender was associated with an ultimate diagnosis of IBS (OR 5, p < 0.02). Older age was associated with NSAIDs enteritis, while more subjects without significant gastrointestinal disease were anemic on presentation. Conclusion The majority (49%) of NSE patients do not develop significant small bowel disease. CD occurred in 19% of NSE patients on follow up. Clinical suspicion and capsule severity are predictive of Crohn’s disease on initial CE.

Laryngopharyngeal reflux (LPR) is a clinical entity diagnosed by history laryngoscopic findings that has a variable response to empiric proton-pump inhibitor (PPI) therapy. While the reflux finding score (RFS), an endoscopic scoring scheme, has been advanced as a measure of LPR, it has not been externally validated against symptom severity in practice. Extralaryngeal pharyngeal endoscopic findings may have diagnostic utility but remain underexplored. This study assesses the correlation between extralaryngeal findings and (1) 24-hour oropharyngeal pH & (2) PPI response in patients with suspected LPR. Subjects presented to a tertiary care center with laryngeal symptoms ≥1 month and reflux symptom index (RSI) ≥13. Following baseline questionnaires, laryngoscopy, and a 24-hour oropharyngeal pH probe study, subjects were prescribed 8-12 week omeprazole trials. Baseline endoscopic findings were scored in a blinded fashion using the RFS and extralaryngeal score criteria, summatively the 'ELS.' PPI response was defined as ≥50% improvement in RSI. Thirty-three subjects with flexible endoscopic recordings completed baseline and follow-up questionnaires. The cohort's baseline mean RSI was 23.0 ± 7.2 with a ΔRSI = 9.8 after PPI therapy. The baseline RFS score averaged 5.3 ± 2.7. 45% of our subjects was found to be PPI responsive. The Cohen's kappa for the ELS but not the RFS was significant. There were no significant differences between the RFS (P = 0.10) or ELS (P = 0.07) for PPI responders & nonresponders. Oropharyngeal pH measures did not correlate with the RFS or ELS. In conclusion, endoscopic scores of laryngeal and extralaryngeal findings did not predict PPI response or oropharyngeal acid exposure in suspected LPR.

There is lack of available evidence to help clinicians to predict significant disease and long-term prognosis.Aim: To define the natural history of NSE in an Irish cohort. Methods: Patients with a finding of NSE were identified from a database. Subsequent investigations, treatments and diagnosis were recorded. Patients were grouped based on ultimate diagnosis: Crohn’s disease (CD), Irritable bowel syndrome (IBS), NSAIDs enteritis (NSAIDs), persistent NSE and no significant disease (NAD).Results: 88 patients, 46 (52%) male, mean age 52 +- 17.8 years were included with a mean follow up of 23 +- 19 months. The ultimate diagnoses were NAD=43 (49%), CD =17 (19%), IBS =14 (16%), NSAIDs =12 (14%) and persistent NSE=2 (2%). Significantly, more patients diagnosed with CD on follow up were referred with suspected CD. CD= 14/17 (82%) vs 13/57 (23%), p < 0.001. While a diagnosis of CD was associated with a positive baseline Lewis score (>135); 11/17 (65%) CD versus 16/ 71 (23%). Female gender was associated with an ultimate diagnosis of IBS (OR 5, p <0.02). Older age was associated with NSAIDs enteritis, while more subjects without significant gastrointestinal disease were anemic on presentation.Conclusion: The majority (49%) of NSE patients do not develop significant small bowel disease.
