Many studies evaluate dysphagia in elderly patients and compare their swallowing to younger controls to assess the degree of swallowing impairment. Previous research suggests that changes should be expected in swallowing due to aging, and these changes need to be considered when performing swallowing assessments. A systematic review was conducted to elucidate the timing of swallowing in healthy. A comprehensive multiengine literature search was conducted to find articles studying swallowing in the healthy elderly, which yielded 22,852 articles of which 11 were judged to be relevant...

BACKGROUND: Globus pharyngeus is common and has a low cure rate. Its etiology is complex and reported to be associated with laryngopharyngeal reflux (LPR). However, some patients with globus do not exhibit any reflux symptoms or respond to proton pump inhibitors (PPIs) treatments. The purpose of this study was to clarify the related risk factors of these patients with a final objective of improving the curative effect. METHODS: Forty two patients afflicted with globus pharyngeus (G group) and 38 patients without globus pharyngeus (NG group) were included in this study...

On the basis of 20 years' experience, the authors present the immediate and long-term results of operative treatment of Zenker's diverticulum. Comparison of two methods of surgery - diverticulopexia (in 21 patients) and excision (in 16), both associated with upper esophageal sphincter myotomy - shows good immediate and longterm results (from 1 to 19 years), with disappearance of symptoms (dysphagia) in all patients. There was no perioperative mortality. Postoperative complications were most commonly of pulmonary origin and were observed in a third of patients in both groups...

OBJECTIVES/HYPOTHESIS: Aspiration of gastric refluxate is one of the most commonly observed complications among long-term nasogastric tube (NGT) fed patients. The upper esophageal sphincter (UES) pressure barrier is the main defense mechanism against pharyngeal reflux of gastric contents. Our objective was to investigate the efficacy and safety of the UES assist device (UES-AD) in preventing gastric reflux through the UES in long-term NGT-fed patients. STUDY DESIGN: Self-Controlled Case series...

INTRODUCTION: Distal esophageal baseline impedance (BI) levels reflect the esophageal mucosal integrity in reflux disease. Systemic sclerosis (SSc) could potentially affect the integrity of esophageal mucosa and consequently impair distal and proximal BI levels, but data in this regard are lacking. AIM AND METHODS: We aimed to prospectively investigate and compare BI levels among non-erosive reflux disease (NERD), SSc patients, and healthy controls (HCs). Consecutive patients with reflux symptoms and well-defined diagnosis of SSc underwent upper endoscopy and, in case of no lesions encountered, manometry and impedance-pH testing off-therapy...
