Preparation Before the Procedure

Day of the Procedure
The procedure time is approximately a half hour. A topical anesthetic agent is put in the back of the throat to decrease the gag reflex. While the patient is lying on his side, a soft thin tube is put in the nose or mouth into the esophagus. Measurements are taken while the patient swallows water. Once pressures are measured, the tube is withdrawn and the patient is discharged. [Back to the top]
The exam gives your physician documentation on how your esophagus is functioning. Results of the exam will determine the appropriate treatment.
Side Effects and Complication
No serious problems are associated with esophageal manometry. You may experience some slight, temporary gagging during tube placement and a slight sore throat after the exam. [Back to the top]
