Filter by:The aim of this study is to evaluate standard investigations performed in patients with bolus impaction in a prospective observational field study. In bolus impaction, ingested food boluses have to be endoscopically removed. Oesophageal narrowing by scar tissue caused by reflux disease or motility disorders are possible causes of bolus impaction. How common these causes are has up to date never been investigated. The discovery of eosinophilic oesophagitis has broadened differential diagnosis of bolus impaction. Currently high resolution oesophageal manometry and 24-hour pHmetry are performed in addition to endoscopy in the assessment of bolus impaction at the University Hospital Zurich. The collection of these examination results is the aim of this prospective unrandomised observational field study to assess weather the currently applied procedures are valid to diagnose the cause of impaction to find optimal therapy for each patient.
This study evaluates the effect of botulinum toxin 100 U or saline, injected endoscopically in the distal esophagus, on symptoms and manometry pattern in patients with diffuse esophageal spasm.
Achalasia and esophageal spasm are primary esophageal motility disorders where the lower esophageal sphincter fails to relax in response to swallowing with no well understood underlying cause. Surgical myotomy represents an appropriate therapeutic option. The purpose of this study is to evaluate flexible endoscopic myotomy a novel therapeutic approach to overcome the need for invasive surgery.
The purpose of this study is to determine whether esophageal dysmotility and dilatation is an important complication in the long term follow-up following laparoscopic gastric banding for morbid obesity.
The purpose of this research project is to determine the effect of a drug called bethanechol on swallowing function in patients with Ineffective Esophageal Motility (IEM). This drug is FDA approved for use in treating other conditions, but not for the treatment of IEM. There is currently no approved therapy for the treatment of IEM. This information is important for the possible development of new ways of treating patients with IEM and for the effectiveness of topically applied Bethanechol on patients with IEM.
In the current study we plan to evaluate the effects of the conversion from gastric banding to gastric bypass on esophageal function using combined monitoring. The primary aim of the current study is to evaluate esophageal function before and 3-months after the conversion from gastric banding to gastric bypass. A second objective is to evaluate the severity of symptoms, esophageal dysmotilities, endoscopic abnormalities and bolus retention found in patients referred for conversion from gastric banding to gastric bypass. Our hypothesis is that esophageal motility disorders associated with gastric banding are reversed by conversion to gastric bypass.
The primary objective of this study is to compare the accuracy of esophageal and anorectal manometric pressure measurements using a newly developed air filled balloon catheter with present standard solid state esophageal and anorectal catheters, respectively.
Noncardiac chest pain (NCCP) is a common clinical problem worldwide. In Hong Kong, it has been estimated that about 20% of patients with chest pain are misdiagnosed to have coronary heart disease. Despite its benign nature, this condition causes anxiety, impairs quality of life and consumes a substantial amount of healthcare resources. While acid reflux and motility disorder in the esophagus are often attributed as the cause of NCCP, visceral hyperalgesia of esophagus is now recognized to play a central role in the pathogenesis of this condition. This research project aims to evaluate the role of visceral hyperalgesia in Chinese patients with NCCP. NCCP patients will be evaluated for the prevalence of gastroesophageal reflux disease and esophageal motility disorder by endoscopy, manometry and pH study. The visceral sensory and pain thresholds of these patients will be compared with asymptomatic controls.
