background and objective: numerous anatomical abnormalities or pathological conditions can cause upper airway obstruction in obstructive sleep apnea syndrome (osas). muller’s maneuver (mm) is one of diagnostic modalities investigating the obstruction site in patients with osas. this study aimed to investigate the obstruction sites of patients with osas based on mm. materials and methods: this w...

background: coeliac disease (cd) is characterized by malabsorption resulting from inflammatory injury to the mucosa of the small intestine by an inappropriate immune response to dietary gluten proteins. the aim of this study was to assess the prevalence of cd in our endoscopy unit by taking routine duodenal biopsies during upper gi endoscopy. materials andmethods: nine hundred and thirteen pati...

most of the ingested foreign bodies pass uneventfully through the gastrointestinal tract. however, long and rigid foreign bodies are associated with an increased risk of gastrointestinal impaction, perforation, and bleeding. spontaneous passage of a toothbrush has not been reported till date and the technique of its removal is a curiosity for surgeons. endoscopy is a recommended technique for t...

OBJECTIVE This study examines subjects' level of consciousness with bispectral analysis in sedation endoscopy of the upper airway. STUDY DESIGN A prospective study. SETTING University hospital. SUBJECTS AND METHODS Bispectral analysis levels recorded in natural sleep of 43 patients with obstructive sleep apnea during an overnight polysomnographic sleep study were directly compared with th...

OBJECTIVE To describe upper airway collapse patterns observed on drug-induced sedation endoscopy (DISE) during screening for a clinical trial and to evaluate the impact of collapse patterns found on preoperative DISE on response rates to upper airway stimulation (UAS) therapy. STUDY DESIGN Retrospective review of an ongoing prospective multi-institutional cohort study. SETTING Twenty-two pa...

BACKGROUND Upper airway obstruction is a common complaint in children presenting to otolaryngology clinics. In such children, adenoid hypertrophy is often suspected. There are numerous ways to determine adenoid size, including palpation, mirror examination, endoscopic examination, lateral neck roentgenogram (X-ray), magnetic resonance imaging (MRI), and acoustic rhinometry. Pediatric patient co...

Minimally invasive imaging of upper airway obstructions in children and adults is needed to improve clinical decision-making. Toward this goal, we demonstrate an anatomical optical coherence tomography (aOCT) system delivered via a small-bore, flexible endoscope to quantify the upper airway lumen geometry. Helical scans were obtained from a proximally-scanned fiber-optic catheter of 820 μm oute...

A 71-year-old woman with end-stage renal disease on hemodialysis, hypertension, diabetes, coronary artery disease, and ischemic cardiomyopathy, on hydralazine 300 mg daily for 2 years, presented with a new onset of vesiculobullous rash, dysphagia, odynophagia, throat pain/tightness, and hoarseness. Physical exam showed multiple vesicles in her upper and lower extremities with significant airway...

OBJECTIVES/HYPOTHESIS Drug-induced sleep endoscopy (DISE) is used to determine surgical therapy for obstructive sleep apnea (OSA); however, the effects of anesthesia on the upper airway are poorly understood. Our aim was to systematically review existing literature on the effects of anesthetic agents on the upper airway. DATA SOURCES PubMed, CINAHL, EBM reviews and Scopus (all indexed years)....
