BMC’s Yawkey building doors are now closed as an entrance as part of our ongoing efforts to enhance our campus and provide you with the best clinical care.

All patients and visitors on our main campus must enter our hospital via Shapiro, Menino, or Moakley buildings, where they will be greeted by team members at a new centralized check-in desk before continuing to the hospital. We are excited to welcome you and appreciate your patience as we improve our facilities.

Esophageal Manometry

Select your language:

This test measures the pressure inside the lower esophageal sphincter (LES). A thin tube is inserted through your mouth or nose and into your stomach. Once it is in place, the physician will gently pull the tube back into the esophagus and ask you to swallow. As you do so, the pressure and coordination of your muscle contractions will be measured. If the pressure is low or the LES is not relaxing properly, achalasia may be present. If the pressure is low or the LES is not contracting properly, it may indicate GERD (reflux disease).
