Endoscopic Retrograde Cholangiopanctreatography (ERCP)
This procedure is performed by Dr. David at the hospital to examine your bile ducts (drainage tubes from the liver/gallbladder) and the pancreas. Tissue can be sampled during this examination if needed, and therapeutics may be required depending on your illness, such as the placement of a stent. This procedure is performed at Banner Good Samaritan Medical Center.

Percutaneous Endoscopic Gastrostomy (PEG) tube placement
This procedure is typically reserved for those who are unable to tolerate oral nutrition due to an underlying illness. This procedure is performed at Banner Good Samaritan Medical Center.

Wireless Bravo pH Monitoring
Using Upper Endoscopy (see above), a tiny device the size of a vitamin can be temporarily placed inside your esophagus to measure the pH (i.e. acidity) within your esophagus. This information helps with therapies and medicines to treat various symptoms. This procedure is performed at Banner Good Samaritan Medical Center.

Esophageal Manometery
This is a test where a very thin, flexible probe is passed through the nose into the esophagus. The pressure sensors measure if the esophagus is swallowing correctly and allows us to diagnose many types of swallowing disorders. This test is performed by a certified RN at Banner Good Samaritan Medical Center and the results are interpreted by Dr. David.

Capsule Endoscopy
After ingesting a tiny capsule the size of a multivitamin, the physician is able to take thousands of pictures deep within your small bowel, which would normally be outside the reach of standard upper endoscope. This procedure is performed at our central Phoenix office.

Expert Consultation

Dr. David is board certified in gastroenterology and has undergone extensive training in diagnostic and therapeutic endoscopy.


Colonoscopy
Colonoscopy is recommended for all adults at age 50 (with average risk) for routine colon cancer screening whereby a careful examination is performed to discover and remove polyps. This procedure, which is performed under conscious sedation, has many indications including unexplained diarrhea, rectal bleeding, a family history of colon cancer, and changed bowel habits. Dr. David offers direct access routine screening colonoscopy without the need for an office visit for patients who do not have significant symptoms. This is routinely performed at Arizona Endoscopy Center.

Upper Endoscopy (EGD and Enteroscopy)
Upper endoscopy is performed to examine the esophagus, stomach and small bowel for abnormalities. The indications include frequent heartburn, trouble swallowing, abdominal pain, black stools, ulcer disease, and abdominal pain. This is routinely performed at Arizona Endoscopy Center.
