Endoscopic procedures for stomach cancer

Endoscopic procedures for stomach cancer

These minimally invasive, outpatient procedures allow us to see inside the stomach.

  • EGD: Known as an upper endoscopy, esophagogastroduodenoscopy or EGD, this is the primary test for diagnosing stomach cancer. To undergo an EGD procedure, you first receive medication which sedates you (i.e., makes you relaxed and sleepy). Your gastroenterologist then inserts an endoscope (a thin, lighted tube) into your mouth. He or she passes the endoscope through your throat, down into your esophagus and stomach, and into the first part of your small intestine. The endoscope enables your gastroenterologist to see inside these organs to check for abnormalities such as tumors, ulcers, obstructions and inflammation. He or she obtains biopsies of abnormal tissue through the endoscope. The tissue is then analyzed in our laboratory to determine if cancer is present. An EGD procedure takes approximately 15 minutes to perform.
  • EUS: Endoscopic ultrasound (EUS) helps your gastroenterologist examine your stomach and organs such as your pancreas, liver, gallbladder and bile duct. This test for stomach cancer uses sound waves to identify tumors and nearby lymph nodes to which the cancer may have spread. EUS allows your gastroenterologist to determine if cancer has spread through multiple layers of your stomach, helping your doctors to stage the disease and tailor your treatment plan.

What is an endoscopic procedure?

The gastroenterologists at CTCA use imaging guidance and innovative tools to perform minimally invasive endoscopic procedures and tests that aid in diagnosing stomach cancer, as well as treating the disease. An endoscopic procedure refers to examining the inside of the body using an endoscope, an instrument that usually has a light attached, which is inserted directly into a body cavity or organ.
