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.
