Patients presenting for colonoscopy: A great opportunity to screen for sleep apnea.

Aim: To discover the prevalence and the feasibility of screening for obstructive sleep apnea (OSA) in patients presenting for routine colonoscopy.

Methods: Adult patients having a colonoscopy for routine indications at our outpatient endoscopy center were eligible if they did not carry a diagnosis of OSA or had not had a prior sleep study. All patients were administered the Berlin questionnaire prior to the procedure.

Airway observations during upper endoscopy predicting obstructive sleep apnea.

Background: This pilot study examined airway characteristics during upper endoscopy to determine who is at high risk for obstructive sleep apnea.

Methods: Patients undergoing routine upper endoscopy were divided into 2 groups according to the Berlin Questionnaire (high and low risk for sleep disordered breathing). Patients underwent routine upper endoscopy using propofol sedation.
