The upper gastrointestinal (GI) tract is an important part of the digestive system. It is comprised of the throat, esophagus, stomach, and upper part of the small intestine (bowel) called the duodenum. Several conditions can impact one or more of these structures and are referred to as upper GI conditions. Some of the most common upper GI conditions include ulcers, esophagitis, gastroesophageal reflux disease (GERD), esophageal stricture, cancer, and cyclic vomiting syndrome (CVS). Should you or a loved one experience symptoms such as trouble swallowing, vomiting, pain, or heartburn, your medical provider may refer you to Colorado Gastroenterology for an upper GI endoscopy procedure. Our Denver, CO gastroenterologists may perform this procedure to diagnose or treat a variety of gastrointestinal concerns.

The GI providers at Colorado Gastroenterology commonly perform endoscopic procedures to detect, evaluate, and treat diseases and conditions affecting the upper GI tract. use procedures to either test for or treat health conditions in the upper GI tract. Some of these include:

  • Upper GI endoscopy: With this procedure, a scope containing a small camera is inserted through the mouth into the esophagus, stomach, and upper part of the small bowel.
  • Capsule endoscopy: An advanced treatment option, a capsule endoscopy involves swallowing a tiny capsule containing a special camera that is used to take images of the GI structures as it migrates through the digestive tract.
  • Esophageal pH/impedance and Bravo pH: These reflux monitoring systems measure the amount of acid reflux affecting the esophagus over a certain period of time.
  • Endoscopic ultrasound: This approach combines an endoscope inserted into the upper GI tract with ultrasonic technology (sound waves) to create diagnostic images of the gastrointestinal structures and surrounding tissues.
  • Laparoscopy: During a laparoscopic upper GI procedure, a small instrument is inserted into the treatment area through a small incision to remove tissues or perform other surgeries.

To perform an upper GI endoscopy, our highly trained gastroenterologists insert an endoscope through the mouth throat down into the upper GI tract (esophagus, stomach, and/or duodenum). An endoscope is a long, pliable tube fitted with a light and a high-resolution camera. With the camera, our team can see and evaluate the internal portions of the digestive tract. The images from the endoscope are transmitted to a computer screen, allowing us to identify and diagnose areas of bleeding, inflammation, and abnormal tissues with greater accuracy than x-ray images.

With the tiny camera, your doctor can see your digestive system from the inside. The images from the camera are magnified and projected onto a computer screen. These images detect problems like inflammation and bleeding better than x-rays. In addition to their diagnostic capabilities, upper GI endoscopies also allow for the removal of polyps (growths), blockages, and tissues samples for biopsies along with the control of bleeding and dilation of structures (like the esophagus) to widen narrow passageways.

Following the endoscopy procedure, your GI provider will discuss the findings of the exam. As biopsy specimens are typically sent to a pathology lab for testing, any biopsy results will usually take about a week to receive.
