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.

All patients undergoing upper endoscopy for removal of a food bolus are asked to sign the standard clinical informed consent form for interventional endoscopy of the Division of Gastroenterology at the University Hospital Zurich. After Diagnosis of food impaction has been made, the food bolus has been removed and the endoscopy has been completed, the patient will be informed of the Diagnosis and the standard procedure of care (High resolution manometry, pH-monitoring, blood sampling) will be explained, and an appointment for these procedures will be given (1-4days thereafter).
