High Resolution Manometry After Partial Fundoplication for Gastro-oesophageal Reflux

"High-resolution manometry is an outpatient examination and part of our routine diagnostic or pre-operative evaluation in GERD.~A thin catheter is placed through the nose into the esophagus, local anaesthesia can be used if the patient experiences a discomfort. Once the tip of the manometry catheter is placed below the esophagogastric junction, the patient is asked to take in water and bread. In rest and during deglutition, pressure measurements are registered with the manometry catheter, allowing the investigator to detect IEM. The examination takes about 1.5 hours. The manometry is a standard and routine intervention being performed for over 30 years with minimal risks.~The GSRS questionnaire pre- and postoperatively is part of our standard workup, no additional assessment for this study is needed."
