A colonoscopy is prescribed by a doctor during a preliminary visit, a colonoscopy is a visual tool used for diagnosing and treating diseases of the large intestine

Open Access Colonoscopy

An open access colonoscopy allows healthy, age-appropriate patients to easily schedule a screening colonoscopy, usually without a pre-procedure visit.


Gastroenterology Associates offers in-house Certified Registered Nurse Anesthetists (CRNAs) to provide anesthesia care to patients receiving endoscopic procedures

Capsule Endoscopy

A capsule endoscopy is an imaging test for the small intestine that uses a camera the size of a pill.

Upper GI Endoscopy (EGD)

An EGD is a visual tool used to examine the lining of the upper part of the gastrointestinal tract.


An Endoscopic Retrograde Cholangiopancreatography (ERCP) is used to identify issues of the bile ducts, liver, gallbladder, or pancreas.

Hydrogen Breath Test

A hydrogen breath test provides information about the digestion of certain sugars or carbohydrates, such as lactose (milk sugar) or fructose (fruit sugar). This test will help determine if you are intolerant to certain sugars.

Flexible Sigmoidoscopy

A flexible sigmoidoscopy is a visual examination of the inside of the rectum and lower part of the colon.

Esophageal Manometry

Esophageal manometry is a test to measure the esophageal contraction, relaxation and peristalsis.  During esophageal manometry, a thin, pressure-sensitive tube is passed through the nose, down the esophagus, and into the stomach. The test takes about 15 – 20 minutes.  The tube is removed after the test is completed.  

Bravo- PH Study

Bravo esophageal pH monitoring is a minimally invasive test that evaluates whether acid from the stomach is refluxing into the esophagus and causing various symptoms. It requires attachment of a small monitoring device onto the esophageal wall during an endoscopic procedure called upper endoscopy or EGD.

Ambulatory PH- Impedence Study

Your doctor may recommend Ambulatory Esophageal Reflux Testing (pH-Z monitoring).  This is a catheter-based test using a combination of pH and impedance sensors for the identification of both acid and non-acid reflux (that may be contributing to PPI Refractory Reflux Disease). It can evaluate the number of reflux events, the acid content of each event and how long each event lasted. This enables your physician to improve management of Gastroesophageal Reflux Disease (GERD) and develop the best care plan.
