The Heartburn Center at Swedish Medical Center is dedicated to providing the correct diagnosis from the start. We then use that diagnosis to create each patient's individualized treatment plan. Our diagnostic testing may include:
TransNasal Endoscopy (TNE)
This procedure provides a visual evaluation of the back of the throat, esophagus and upper part of the stomach by inserting an ultra-thin endoscope (small tube with a camera) through the nose into the esophagus and lower stomach. It is offered without sedation, using local anesthesia. This procedure helps diagnose disorders of the throat, esophagus and upper stomach and can help create a surgical plan, if needed.
EsophagealGastroDuodenoscopy (EGD)/ Upper GI Endoscopy
This procedure offers our team a look at the esophagus, stomach and first part of the bowel (duodenum). This test can diagnose conditions such as erosions, ulcers and hiatal hernias; it also allows for biopsies and the stretching of a narrowed esophagus. It is performed under sedation and a small, lighted tube with a camera is passed through the mouth into the esophagus, stomach and duodenum.
High Resolution Impedance Manometry (HRIM)/Esophageal Manometry
This procedure is performed by inserting a small tube (catheter) through the nose into the esophagus (local anesthesia is provided). Small amounts of salt water are ingested throughout the test's 10-15 minutes. It measures the pressure and fluid movement of the esophagus and lower esophageal sphincter. This test helps diagnose esophageal motility disorders and is important in planning esophageal surgery.
24 Hour Esophageal Impedance PH Test
This test measures the levels of gastric reflux in the esophagus during 24 hours. A small tube (catheter) is inserted through the nose into the esophagus. It is connected to a pocket-sized recording device that hangs over the patient's shoulder. The patient resumes normal activity and returns 24 hours later to have the device removed. This test is the most accurate documentation of gastroesophageal reflux (GERD).
Bravo Capsule Esophageal PH Test
The Bravo Capsule test also measures the levels of gastric reflux in the esophagus, but does so through a small vitamin pill-sized transmitter. This transmitter can be placed through the mouth via a small tube/catheter; it then suctions to the esophagus and the catheter is removed. It also can be placed during a sedated endoscopy. The transmitter sends information to a pocket-sized receiver the patient carries during the 48-hour test. About three to seven days after placement, the transmitter passes through stool.
Cine Esophagram (Video Barium Swallow)
This test is performed with X-ray technology. The patient is asked to swallow a chalky-tasting thick liquid (barium) and a pill. During the swallows, X-ray video is taken. This test helps diagnose swallowing and reflux conditions and is often used for patients with esophageal and gastric problems.
Solid Gastric Emptying Study (SGE)
During this test, the patient is given eggs that have been labeled with radioactive material. After eating the eggs, the stomach is scanned, hourly for four hours, to evaluate how long it takes the stomach to empty. This test helps diagnose gastroparesis and other gastric motility disorders.
