Pediatric Neurogastroenterology and Motility Program

Our Procedures

Our team is always searching for new ways to diagnose and manage motility disorders. We will guide your family through this process and help you every step of the way. We perform the following tests to diagnose motility issues:

  • High-Resolution Esophageal Manometry

      This procedure helps us diagnose digestive problems. It uses a small, pressure-sensitive instrument that is inserted through your child's nose and into his stomach to measure muscle contractions in the esophagus (feeding tube that goes from the stomach to the throat). The test can last from 30 minutes to one hour.

  • Esophageal Multichannel Intraluminal Impedance (MII)

      This test is used to measure movement of substances in the esophagus. It is done with manometry testing to provide information about how your child swallows. This procedure can also be used with pH or acid testing to see if your child is suffering from reflux.

  • Antroduodenal Manometry (AD)

      This measures the activity of your child’s stomach and small intestines. A small tube with pressure sensors measures the activity of your child’s gastrointestinal (GI) tract. The tube will be inserted while your child is under anesthesia—medicine that will put him to sleep so he will not feel anything during the procedure. 

      The tube will stay in place until the next day to give the sleep medicine time to wear off. This test lasts for approximately six hours. We will give your child medicine and special meals during the test to help us understand how medicine and food affects his GI tract. 

  • Colonic Manometry

      This is a test of the small and large intestines that measures pressure and movement in your child's colon. We will prepare your child for this procedure by cleaning his colon of fecal matter. 

      The following day, your child will be given anesthesia (sleep medicine) so that we can insert a small tube called a colonoscope and smaller tube with sensors (about the size of a straw) to measure the activity of the colon. The test will take about six hours. Your child will feel no discomfort from the tube.

  • Anorectal Manometry (ARM)

      This procedure tests patients with constipation or fecal incontinence. A small, flexible tube, about the size of a thermometer with a small balloon at the end, is inserted into your child’s rectum. 

      This tube is connected to a machine that measures pressure. When the balloon is inflated, our doctors can measure your child's response. The procedure takes about 30 minutes, and your child may feel some mild discomfort.
