Our office has the Video Capsule, also known as Pillcam or Capsule Endoscopy. This is a tiny camera, in the size of a medicine pill, that allows us to visualize the esophagus (Pillcam Eso) and small intestine (Pillcam SB) without needing any procedures or surgeries. The study is performed within the office and the result often is available within 24 hours

Dr. Nguyen has collaborated with St. Lucie Medical Center to acquire the Bravo pH monitor. This is a unique, catheter-free capsule that is placed within the esophagus. It allows us to monitor and record the acid refluxing into the esophagus over 24 to 48 hrs. It also correlates the symptoms of reflux with the pH changes occurring within the esophagus, even during sleep. The best part of the probe is that the patient can maintain normal daily activities and diets, while it transmits and records important data relating to the patient's disease. The physician will use this information to properly treat and provide important recommendations to the patient. This is an outpatient procedure and the result is often available within 1-2 days.

Recently, Dr. Nguyen and St. Lucie Medical Center had obtained the Spyglass Cholangioscopy video scope. It is the most current state-of-the- art equipment and technology to allow Dr. Nguyen to directly visualize, treat and correct any abnormalities, from gall stones to cancer, associated with the bile duct leading into the liver and gall bladder. He and the hospital are the only ones that can effectively operate and provide this modern and high tech machinery along the Treasure Coast. Only Orlando and West Palm Beach are the nearest area that has this technology. After many successful cases, Dr. Nguyen has become very efficient and effective in providing this type of meticulous care.

The physician is also well trained in motility disorder of the entire intestinal tract. Therefore, he can perform and analyze studies and tests to diagnose and treat any illnesses such as difficulty swallowing (dysphagia), stool soiling (stool incontinence), chronic constipation, recurrent bowel obstruction, etc.
