Pressure measurement in the esophagus
(High-resolution manometry)Pressure measurement in the oesophagus is useful for certain diseases of the oesophagus. For example, if the movement of food is impaired (motility disorder) or the lower esophageal sphincter is narrowed at the junction with the stomach (achalasia). The examination is also recommended before anti-reflux surgery, which is intended to prevent the reflux of stomach acid.
During the procedure, a special probe with 36 measuring points measures the pressure conditions in the oesophagus. A wafer-thin probe is inserted into the oesophagus via the mouth and throat and pushed further into the stomach. The probe is then slowly pulled out again, with the actual measurement taking place at various points. The patient is asked to drink a few sips of water. This creates a pressure profile of the esophagus. The results of the examination can be discussed with the physician immediately afterwards.
Manometry is also used for unclear swallowing disorders, chest pain that cannot be attributed to heart problems or suspected systemic diseases involving the oesophagus.
Before the examination
No special preparation is necessary. A fasting period of six hours is recommended. The throat is locally anesthetized for the examination.
After the examination
Any form of food can be eaten immediately after the examination. Any discomfort in the throat after the appointment is generally harmless and disappears spontaneously.
