Dysphagia is a common problem in the elderly population with an especially high prevalence in hospitalized and institutionalized patients. If inadequately addressed, dysphagia leads to significant morbidity and contributes to decreased quality of life. Dysphagia can be categorized as emanating from either an oropharyngeal or esophageal process. A disproportionate number of elderly patients suffer from oropharyngeal dysphagia with a multifactorial etiology. Historically, treatment options have been limited and included mostly supportive care with a focus on dietary modification, food avoidance, and swallow rehabilitation...

A 43-year-old man with complaints of increased difficulty of swallowing and weight loss underwent videofluorographic examination of swallowing, which revealed severely reduced cricopharyngeal opening. Endoscopic cricopharyngeal myotomy was performed using a modified technique (mECPM). A benign fibrotic stricture of the upper esophageal sphincter (UES) was identified under visualization of a distending operating laryngoscope. A vertical midline incision in the strictured mucosa and submucosal resection of the cricopharyngeal muscle were performed using a CO2 laser...

C A Gutschow, P Bauerfeind
Over the last 20-30 years, treatment of pharyngoesophageal diverticula was subject to a number of fundamental changes. Considering the classical open transcervical approaches, the necessity for myotomy of the upper esophageal sphincter with the goal of interrupting the pathogenesis of the disease has become a standard component of the operation. On the other hand, with the growing popularity of rigid and flexible endoscopic techniques, pharyngoesophageal diverticula are increasingly being treated by gastroenterologists and otorhinolaryngologists, often with the argument of a technically easier and less invasive procedure; however, it remains unclear whether this shift towards endoscopic techniques truly translates into better outcome quality...

BACKGROUND: The upper esophageal sphincter (UES) reflexively responds to bolus presence within the esophageal lumen, therefore UES metrics can vary in achalasia. METHODS: Within consecutive patients undergoing esophageal high-resolution manometry (HRM), 302 patients (58.2±1.0 year, 57% F) with esophageal outflow obstruction were identified, and compared to 16 asymptomatic controls (27.7±0.7 year, 56% F). Esophageal outflow obstruction was segregated into achalasia subtypes 1, 2, and 3, and esophagogastric junction outflow obstruction (EGJOO with intact peristalsis) using Chicago Classification v3...

OBJECTIVE: When eating solids, stage II transport (St2Tr) propels triturated food into the pharynx for bolus formation and storage before swallowing. Although the existence of St2Tr is acknowledged, the reason for its existence remains unclear. Understanding it may facilitate development of food appropriate for individuals with dysphagia. The purpose of this study was to explore how measures of duration of eating and swallowing affect the number of St2Tr cycles. DESIGN: Videofluorography was performed on 13 healthy subjects eating 6-g squares of banana, tofu, and cookies...

Although the modified balloon dilatation therapy has been demonstrated to improve pharyngeal swallowing function post stroke, the underlying neural mechanisms of improvement are unknown. Our aims are (1) to investigate the effect of modified balloon dilatation on the excitability of corticobulbar projections to the submental muscle in dysphagic patients with brainstem stroke and (2) the relation between changes in excitability and pharyngeal kinematic modifications. Thirty patients with upper esophageal sphincter (UES) dysfunction due to unilateral brainstem stroke were recruited into two groups...

OBJECTIVES/HYPOTHESIS: External cricoid pressure is increasingly used to augment the upper esophageal sphincter (UES). Our objective was to determine the effect of 1) pressures applied to cricoid, supracricoid, and subcricoid regions on the length and amplitude of the UES high-pressure zone (UESHPZ), and 2) the external cricoid pressure on lower esophageal sphincter (LES) tone. STUDY DESIGN: Case-control study. METHODS: We studied 11 patients with supraesophageal reflux (mean age 58 ± 12 years) and 10 healthy volunteers (mean age 47 ± 19 years)...

The motility of the pharynx, upper esophageal sphincter (UES), and proximal esophagus in patients with oropharyngeal dysphagia is still not entirely understood. High-resolution manometry (HRM) was recently added to the armamentarium for the study of this area. This study aims to describe HRM findings in patients with vagal paralysis. Sixteen patients (mean age 54 years, 69% females) with oropharyngeal dysphagia due to unilateral vagal paralysis were prospectively studied. All patients underwent HRM. Motility of the UES and at the topography of the velopharynx and epiglottis were recorded...

REVIEW
M Jungheim, M Ptok
BACKGROUND: To transport a bolus from the mouth into the stomach, regular contraction of the pharyngeal muscles and a coordinated function of the upper esophageal sphincter (UES) are necessary. The muscle contraction generates intraluminal pressure, which pushes the bolus continuously forward. In contrast to imaging studies, manometric methods enable assessment of intraluminal pressure buildup and the function of the muscles involved. These methods were initially established for the esophagus and have been used increasingly in the pharynx for 7-8 years...

OBJECTIVES/HYPOTHESIS: Quantitative measures of swallowing function may improve the reliability and accuracy of modified barium swallow (MBS) study interpretation. Quantitative study analysis has not been widely instituted, however, secondary to concerns about the time required to make measures and a lack of research demonstrating impact on MBS interpretation. This study compares the accuracy of the penetration/aspiration (PEN/ASP) scale (an observational visual-perceptual assessment tool) to quantitative measures of airway closure timing relative to the arrival of the bolus at the upper esophageal sphincter in identifying a failure of airway protection during deglutition...

BACKGROUND: The association between laryngopharyngeal reflux (LPR) and abnormalities of upper esophageal sphincter (UES) and esophageal motility is not clearly known. High-resolution esophageal manometry (HREM) has allowed accurate measurement and evaluation of UES and esophageal function. GOALS: To evaluate the UES function and esophageal motility using HREM in patients with LPR and compare them to patients with typical gastroesophageal reflux disease (GERD). STUDY: All patients evaluated for GERD or LPR symptoms with esophageal function testing including HREM, ambulatory distal pH monitoring and upper endoscopy between 2006 and 2014 were retrospectively studied (n = 220)...
