AI Article Synopsis
- The study investigated whether upper GI endoscopy can predict obstructive sleep apnea syndrome (OSAS) by examining patients with laryngo-pharyngeal collapse.
- Among 154 subjects with laryngo-pharyngeal collapse, a significant 70.1% were diagnosed with OSAS compared to only 7.7% of control subjects, showing a strong link between airway obstruction and OSAS.
- Findings suggest that endoscopy could serve as a valuable diagnostic tool, particularly highlighting male sex, higher BMI, and severe obstruction as key predictors of OSAS.
Article Abstract
Background/aims: Despite the high prevalence of obstructive sleep apnea syndrome (OSAS), most individuals are unaware of its diagnosis. We assessed whether an upper gastrointestinal (GI) endoscopy can accurately predict the incidence of OSAS.
Methods: After endoscopic evaluation of laryngo-pharyngeal collapse, a total of 154 subjects with laryngo-pharyngeal collapse and 52 control subjects underwent polysomnography. Based on the modified Fujita Classification, upper airway obstruction was classified into 3 different types: oropharyngeal, supraglottic and combined type, and associations between upper airway obstruction and OSAS were evaluated.
Results: Of 154 subjects with laryngo-pharyngeal collapse, 108 (70.1%) were diagnosed as OSAS, while only 4 (7.7%) control subjects were diagnosed as OSAS (p < 0.001). The sensitivity and specificity of endoscopic diagnosis were 96.4 and 51.1%, respectively. Oropharyngeal involvement was frequently found in 90.2% of the subjects (139/154). The severity of upper airway obstruction was significantly correlated with the apnea-hypopnea index score (r = 0.55, p < 0.001). A multivariate logistic regression analysis revealed that a male sex (OR 5.20; 95% CI 2.65-10.2, p < 0.001), body mass index ≥25 kg/m2 (OR 4.98; 95% CI 2.23-11.2, p = 0.02) and severe obstruction (OR 7.79; 95% CI 3.34-18.2, p < 0.001) were significant independent predictors of severe OSAS.
Conclusion: A conventional upper GI endoscopic examination might be useful as a diagnostic modality for OSAS.

Background: Post thyroidectomy hemorrhage is a potentially life-threatening complication. As the mechanism leading to hypoxemic brain damage and death is still unknown, our aim was to examine the underlaying pathophysiology in an animal model.
Methods: A series of experiments was performed in our established model for post thyroidectomy hemorrhage in 6 pigs.
