Background

It remains unclear whether patients diagnosed as having obstructive sleep apnea (OSA) incidentally while undergoing gastrointestinal endoscopy under conscious sedation (GE-CS) have predominantly mild disease.

Materials and Methods

We evaluated differences in the disease characteristics, severity and treatments received between patients who were suspected as having OSA during GE-CS (GE group, n = 56) and patients who visited our hospital with a history of OSA-related symptoms (SY group, n = 123).

Results

The median age of patients, percentage of men and percentage of patients with obesity were 54 years, 68%, and 21% in the GE group and 51 years, 78%, and 31% in the SY group, respectively. The percentages of patients with mild, moderate, and severe OSA were 18%, 36%, and 43% in the GE group and 30%, 17%, and 39% in the SY group, respectively. The percentages of patients with subjective symptoms (e.g., daytime sleepiness/tiredness, 61% vs. 75%, p = 0.056) and scores on the Epworth sleepiness scale of ≥ 11 (18% vs. 37%, p = 0.009) were lower in the GE group, whereas there was no difference in the proportion of patients with objective symptoms (e.g., loud snoring or apnea, 70% vs. 70%) between the two groups. Patients with moderate-to-severe OSA who received continuous positive airway pressure (CPAP) therapy were fewer in the GE group (34% vs. 65%, p = 0.001).

Conclusion

A large percentage of patients with OSA diagnosed incidentally while undergoing GE-CS had moderate-to-severe disease but refused CPAP as they often had few subjective symptoms.
