Gastroenterology, Hepatology & Nutrition

Gastroenterology, Hepatology & Nutrition at Children’s Hospital & Medical Center treats kids from birth to age 19 who are struggling with a variety of eating and digestive problems — from abdominal pain to constipation, food allergies to liver disease.

In addition to diagnosing and treating a wide range of issues, our team of gastroenterologists — doctors who are specially trained to treat kids with eating and digestive issues — works closely with physicians from other specialties to provide individualized care for every child.

For instance, children with food allergies or hypersensitivities might need to be seen by Allergy, Asthma & Immunology specialists. And patients who struggle with swallowing or aspiration may need to be seen by a pulmonologist (a doctor who specializes in breathing issues) or Ear, Nose & Throat (ENT) specialist.

What Sets Children’s Apart?

Gastroenterology, Hepatology & Nutrition at Children’s is the only service of its kind in the state of Nebraska that has specialized clinics of experienced medical teams who are trained to treat all aspects of your child’s condition.

Our clinics include:

  • Aerodigestive: For infants and children who have swallowing and aspiration issues (where food and liquids are inhaled rather than swallowed). We also see kids with GERD, or gastroesophageal reflux disease, when food in the stomach comes back into the throat.
  • Colorectal: For children who have any problems going number two, such as constipation.
  • Feeding and growth: For children who have significantly slower weight gain than their peers (failure to thrive) or other issues related to eating or feeding difficulties. This clinic includes experts in speech and occupational therapy as well.
  • Food hypersensitivity: For children who have any symptoms of food hypersensitivity and allergy.
  • Inflammatory Bowel Disease (IBD): For children who have conditions such as ulcerative colitis and Crohn’s disease.
  • Liver: For children with elevated liver enzymes or liver disease.
  • Nonalcoholic Steatohepatitis (NASH): For children with NASH and other obesity-related liver diseases.
  • Partial Enteral Nutrition (PEN): For children who require supplemental feeding, including tube feeding.
  • Short Bowel: For children with short bowels or who have had bowel resectioning.

We also conduct clinical trials that involve the latest and most effective treatments for conditions such as liver disease, motility disorders, and intestinal failure.

We participate in ImproveCareNow, which allows us to access and share evidence-based practices with other GI facilities. Sharing knowledge with other experts who have seen patients with your child’s condition enables us to provide the highest-quality, most effective care to your child.

Conditions We Treat

Our team is prepared to diagnose and treat many digestive health issues, including:

  • Crohn’s Disease

    A form of inflammatory bowel disease (IBD) in which the lining of the digestive tract is inflamed.
  • Elevated Liver Enzymes

    Liver disease can be the result of a variety of causes, including infections (like hepatitis A, hepatitis B, or hepatitis C), genetic conditions (like hemochromatosis or alpha-1 antitrypsin deficiency), autoimmune diseases (like autoimmune hepatitis), obesity-related liver disease, cancers (such as bile duct cancer or liver cancer).
  • Failure To Thrive

    Significantly slower (or no) weight gain compared to what is considered developmentally appropriate.
  • Gastroesophageal Reflux Disease (GERD)

    When a muscle in the esophagus fails to close correctly, the contents of the stomach may leak back into the esophagus, causing irritation.
  • Gastrointestinal Polyps

    Small growths in the intestines.
  • Hepatitis

    Liver inflammation.
  • Jaundice

    When the liver is unable to properly process broken down red blood cells, a chemical called bilirubin begins to build up inside the body. This can make a person’s skin and the whites of their eyes turn yellow.
  • Nonalcoholic steatohepatitis (NASH)

    A type of nonalcoholic fatty liver disease that includes inflammation and damage to liver cells, as well as fat in the liver.
  • Short Bowel Syndrome

    When nutrients cannot be absorbed properly because the small or large intestines either did not develop properly or had to be fully or partially removed to address another health issue.
  • Ulcerative Colitis

    A form of inflammatory bowel disease (IBD) in which the large intestine and rectum become inflamed and damaged.

We have the latest diagnostic and treatment technologies and equipment to treat children and provide the following procedures, including:

  • Anorectal Manometry

    Studying the anus and rectum using a catheter and a balloon.
  • Antroduodenal Manometry

    Studying the stomach and a portion of the small intestine using a tube inserted through the nose.
  • Capsule Endoscopy

    Using a swallowable camera the size of a pill to examine the small intestine.
  • Dynamic Nutritional Management Of Tube Feeding And/Or Total Parenteral Nutrition

    Ensuring that adequate nutrition is delivered through the G tube or via parenteral nutrition if your child has difficulty absorbing nutrients or taking food by mouth.
  • Esophageal pH Monitoring

    Measuring the frequency that acid from the stomach goes into the esophagus, using a tube inserted through the nose or mouth.
  • Esophageal Manometry

    Examining if the esophagus is working by inserting a tube through the nose down into the esophagus and stomach.
  • Hydrogen Breath Test

    Measuring hydrogen levels in a person’s breath in order to determine if the amount of hydrogen indicates that the body is not digesting certain nutrients properly.
  • Liver Biopsy

    Using ultrasound guidance and a special needle to remove a small piece of liver tissue for further examination.
  • Lower Endoscopy (Colonoscopy)

    Looking at the lower GI tract (colon and small intestine) by inserting a thin and flexible tube through the anus.
  • Nutrition Management Of Dietary Restrictions

    Helping parents of children with dietary restrictions (allergies, intolerance, or feeding difficulties) to select a diet that meets your child’s nutritional needs and promotes healthy growth and development.
  • Pancreatic Stimulation Testing

    Measuring the pancreas’ response to the hormone secretin (produced by the small intestine as partially digested food passes from the stomach).
  • Percutaneous Endoscopic Gastrostomy (PEG)

    Feeding tube placement with the assistance of an upper endoscope.
  • Push Enteroscopy

    Using a special camera inserted into the throat through a thin, flexible tube in order to look further into the small bowel.
  • Upper Endoscopy

    Looking at the upper gastrointestinal tract (esophagus, stomach, and beginning of small intestine) by inserting a thin and flexible tube with a camera attached into the throat.
