Cotton O’Neil Digestive Health Center

The Cotton O’Neil Digestive Health Center is a one-stop shop for patients with digestive disorders. Patients can meet with providers, be tested for digestive health issues in our Endoscopy Center, and learn how to manage digestive health conditions – all under one roof.

Although the Digestive Health Center is a part of Stormont Vail Health, it has its own location outside of the hospital. This gives our patients the best of both worlds: the resources of a large medical group and the personal touch of an close-knit medical practice.

Because digestive health isn’t the only priority, we encourage all of our patients to continue seeing a primary care provider in order to receive annual physicals, screenings, and other important health services.

Common myths about having a colonoscopy

Conditions We Treat

A patient’s journey through the Endoscopy Center usually begins with their primary care provider.

When patients come with symptoms that point to a gastrointestinal disorder – such as heartburn or rectal bleeding – their primary care physicians may refer them for testing and treatment at the Digestive Health Center.

The Center houses a clinic and the Cotton O’Neil Endoscopy Center, a Medicare/Joint Commission-Certified Ambulatory Endoscopy Center. We perform a variety of procedures and tests on a same-day, outpatient basis.

At the center, patients can meet with gastroenterologists for treatment of symptoms and disorders such as:

  • Diarrhea
  • Heartburn
  • Constipation
  • Rectal bleeding
  • Gastric reflux
  • Nausea
  • Vomiting
  • Unexplained weight loss
  • Colitis
  • Crohn’s disease
  • Gastroesophageal reflux disease (GERD)/Acid reflux
  • Esophageal strictures
  • Swallowing disorders
  • Inflammatory bowel disease

Colonoscopies at the Endoscopy Center

Many patients come to the Endoscopy Center for colonoscopies. Colon cancer is the second-leading cause of cancer deaths in the U.S., and the fourth leading cause of cancer deaths in Kansas. The good news is it can be prevented through regular screenings.

Stormont Vail recommends annual colonoscopies for:

  • Patients over age 50
  • Patients with a family history of colorectal cancer
  • Patients whose physicians believe, for any reason, that an annual colonoscopy is indicated.

Patients or providers call (785) 270-4800 to schedule colonoscopies. Patients do not need a referral.

Our Treatments & Services

  • Colonoscopy

    A colonoscopy is a procedure to check for problems in your colon. During a colonoscopy, your physician will use a scope (a tiny camera attached to long, thin tube). The scope looks inside your rectum and colon for swollen or irritated tissue, polyps (growths), ulcers, and cancer.

    You don’t need a referral to schedule a colonoscopy. Call (785) 270-4800 to make an appointment. You can also fill out our online form, and someone will contact you to schedule your colonoscopy.

  • Upper Endoscopy

    An upper endoscopy (also known as upper GI endoscopy or EGD) is a procedure that looks for problems in your upper gastrointestinal tract. The gastroenterologist uses a thin, flexible tube with an attached camera to look at your esophagus, stomach, and duodenum (the first portion of your small intestine).

    An upper endoscopy can check for many different diseases, including:

    • Cancers of the esophagus, stomach, or duodenum
    • Ulcers
    • Inflammation, or swelling
    • Celiac disease: a disorder of the small intestine that makes you unable to eat gluten
    • Narrowing of the esophagus
    • Blockages
    • Gastroesophageal reflux disease (GERD): where your stomach contents come back up into the swallowing tube – often causing heartburn
    • Warning signs of cancer, like precancerous polyps (growths)

    You don’t need a referral to schedule an upper endoscopy. Call (785) 270-4800 to schedule this procedure.

  • Flexible Sigmoidoscopy

    Inserting a flexible, narrow tube with an attached light and camera to look inside the lower colon and rectum. The test looks for swollen or irritated tissue, polyps (growths), ulcers, and colorectal cancer.
  • Polypectomy

    Removing polyps (growths) from the colon. Since polyps can be precancerous, removing them is a key way to prevent colorectal cancer.
  • Endoscopic Ultrasound

    Creating visual images of the digestive tract, stomach lining, and nearby organs (lungs, liver, gallbladder, and pancreas) using sound waves.
  • Fecal Microbiota Transplant

    Placing thawed stool from OpenBiome — a non-profit stool bank — into the lower gastrointestinal tract. This procedure is often used to treat an infection called clostridium difficile, or C. diff., if antibiotics don’t work.
  • Esophageal Dilation

    Stretching and widening narrow areas of the esophagus.
  • Small Bowel Capsule Endoscopy

    Taking pictures of the small intestine using a pill-sized, swallowable video camera. These pictures allow physicians to diagnose occult small bowel disease, and look for causes of gastrointestinal blood loss.
  • Esophageal Motility Testing

    Threading a catheter through the nose and into the esophagus to evaluate the muscle movements that occur while swallowing. This is usually used in patients with swallowing problems, or as a pre-operative test before acid reflux surgery.
  • Bravo™ Reflux Testing System

    Performing an upper endoscopy to measure and record the pH level (acid level) in the esophagus. This can determine if a person has gastroesophageal reflux disease (GERD). It can also determine the effectiveness of medications or surgical treatment for GERD.
  • Endoscopic Retrograde Cholangiopancreatography (ERCP)

    Combining X-rays and an upper endoscopy into one procedure to treat problems of the pancreatic and bile ducts.
  • Barrx™ Radiofrequency Ablation

    Barrx™ radiofrequency ablation: Using a thin, flexible tube with a balloon attached at the end to destroy layers of abnormal or diseased tissue if you have Barrett’s esophagus.
