  • Procedure Information

    • Endoscopic Ultrasound - Endoscopic Ultrasound (EUS) is a highly specialized procedure that is more sensitive than routine X-rays such as CAT scans and even MRI scans for evaluating, staging and sampling GI cancers and GI tract lesions that are below the surface. Dr. Rose Danielson at St. Vincent Physician Network – GI Center is the only physician in southern Montana and northern Wyoming who has completed an Advanced Endoscopic Skills Fellowship in both Endoscopic Ultrasound and Endoscopic Retrograde Cholangiopancreatography. St Vincent's Physician Network- GI center is a referral center for these evaluations and accepts consultations from a wide geographic area.

    • 24 hour pH Monitoring - A catheter is placed through the nose into the stomach to measure stomach acidity in the esophagus for the next 24 hours. Plan to return the following day for the removal of the catheter. During the monitoring, you will keep a diary of any symptoms you experience and record exact times of your activity.

    • Capsule Endoscopy - During a capsule endoscopy procedure, you swallow a tiny camera that's about the size of a large vitamin pill. The capsule contains lights to illuminate your digestive system, a camera to take images and an antenna that sends those images to a recorder you wear on a belt.

    • Colonoscopy - An examination of the lining of the large intestine with a scope. Medications will be given intravenously to help minimize your discomfort and to help you relax.

    • ERCP Biliary Study - An examination of the biliary drainage system under fluoroscopy. Medication will be given intravenously to minimize your discomfort and help you relax. Additional recovery time may be needed after the procedure.

    • Esophageal Manometry - A catheter is placed through the nose into the stomach. We measure the different pressures at different points in your esophagus.

    • Flexible Sigmoidoscopy - An examination of the lower left side of your large intestine with a scope.

    • PEG Tube Insertions - Gastrostomy feeding tube placement is a procedure in which the physician creates an alternate entrance into the stomach. A tube is placed through the abdominal wall directly into the stomach, bypassing the mouth and esophagus. When performed with the aid of a lighted flexible scope it is called Percutaneous Endoscopic Gastrostomy tube insertion (or PEG).

    • Rectal Ultrasound - Endorectal ultrasound (ERUS) is a procedure where a probe is inserted into the rectum and high frequency sound waves (ultrasound waves) are generated. The pattern of echoes as they bounce off tissues is converted into a picture (sonogram) on a television screen.

    • Upper GI Endoscopy (EGD) - An examination of the esophagus, stomach and the first part of the duodenum with a scope. Medication will be given intravenously to minimize your discomfort and help you relax.
