iScan Technology


GI Excellence, Inc. utilizes the most advanced and comprehensive tools possible, empowering us to see more than ever before with unparalleled clarity, precision and resolution.

We utilize the new PENTAX 90 I-FLEX HD scopes providing us 1.25 megapixels of detection power. We now see more than ever before with the highest clarity and truest color. We also are using a straight, raw digital image that needs no conversion. With more data per inch than any other medical image, our HD image at 2X close focus zoom is unmatched in detail with virtually little pixel loss even during those zoom modes. We are the only source in southwest Riversive County to offer such high-definition precision.

GI Excellence, Inc. capitalizes on the only all-computer digital endoscopic platform and highest resolution HD medical image, revealing the once-hidden colors of disease. Through computer generated enhancements, a myriad of calculated tonal, white light, and contrast filters are powerfully applied bringing to life tissue vascularity and tissue topography like never before. Gone are the days of mere single mode, static light filtering techniques. Today, gain the digital dynamics of a virtually limitless number of image enhancements through PENTAX i-SCAN.

Endoscopic Ultrasound (EUS)
Why is Endoscopic Ultrasound (EUS) important to you?

Endoscopic Ultrasound (EUS) brings imaging technologies to the forefront of advancing patient care. Going beyond the layers, the colors of sound bring to life information you need to make confident decisions with unparalleled accuracy.

What are the benefits for using Endoscopic Ultrasound (EUS)?

  • No radiation.
  • Staging of cancers of the esophagus, stomach, pancreas and rectum.
  • Evaluating chronic pancreatitis and other masses or cysts of the pancreas.
  • Studying the bile duct abnormalities including stones in the bile duct or gallbladder, or studying tumors within the bile duct, gallbladder, or liver.
  • Studing the muscles of the lower rectum and anal canal in evaluating reasons for fecal incontinenece
  • Studying submucosal leasions such as nodules or bumps that may be hiding in the intestinal wall covered by normal appearing lining of the intestinal tract.

What is Barrett's Esophagus?

Barrett's esophagus (shown at left) is a pre-cancer condition in which the tissue lining the esophagus (the muscular tube that connects the mouth to the stomach) is replaced by tissue that is similar to the lining of the intestine, called intestinal metaplasia. Patient's with Barrett's esophagus have a much higher risk of developing esophageal cancer compared to the normal population.

The normal esophagus (swallowing tube) is lined by a pinkish-white tissue called squamous epithelium. Some people also have red stomach tissue (normal appearing columnar epithelium) present in the bottom part of the esophagus.

What are Barrett's Esophagus
Risk Factors?


Barrett's esophagus is most commonly diagnosed in middle-aged and older adults; the average age at diagnosis is 55 years. Children can develop Barrett's esophagus, but rarely before the age of 5 years.


Men are more commonly diagnosed
with Barrett's esophagus than women.

Ethnic     Background:    

Barrett's esophagus is equally common in
white and Hispanic populations and is
uncommon in black and Asian populations.


Smokers are more commonly diagnosed
with Barrett's esophagus than nonsmokers.

Patients with intestinal metaplasia have a combined risk of 1.4% per year of progressing to highgrade dysplasia or cancer, which may result in an esophagectomy procedure.

GI Excellence, Inc. GI Excellence, Inc. is committed to a multidisciplinary approach for the treatment of Barrett's esophagus using the latest advances and treatments. As such, we perform focal ablation with the BARRX HALO System HALO90. The HALO90 focal ablation device is designed to treat small areas of Barrett's esophagus, independently or in conjunction with the HALO360 System.

During the Procedure

Using standard endoscopy techniques, the physician activates and controls the different functions of the HALO90 System.

  1. The ablation catheter is first mounted onto the endoscope.
  2. Both devices are introduced into the esophagus.
  3. By manipulating the endoscope, the ablation catheter is positioned within the esophagus at the affected portion of the esophagus.
  4. The physician delivers ablative energy to the targeted tissue. The energy application is less than 1 second and is delivered in an automated manner. The design of this technology limits the energy delivery to a depth clinically shown to remove the diseased tissue (less than 1 mm) while reducing the risk of injury to the deeper tissue layers.
  5. For patients with more than one lesion of Barrett's esophagus, the HALO90 Ablation Catheter is repositioned and the ablation steps are repeated.
