Advanced Diagnostics for GI Conditions

Froedtert & the Medical College of Wisconsin use the most advanced procedures and technology to diagnose the cause of symptoms that occur with digestive tract diseases.

The GI tract, about 28 feet long, consists of the upper and lower GI sections. 

  • The upper GI tract consists of the mouth, pharynx, esophagus and stomach. The esophagus extends through the chest to the stomach, which, in turn, leads to the small intestine. 
  • The lower GI tract comprises the small and large intestines (bowels) and anus. 
  • Related organs include the liver, which secretes bile into the small intestine (using the gallbladder as a reservoir), and the pancreas, which secretes fluid and enzymes into the small intestine. Both of these organs aid in digestion.

The following techniques may be used to diagnose disorders of the digestive tract:

  • Imaging — Uses tools such as magnetic resonance imaging (MRI), compute tomography (CT) and X-rays.
  • Endoscopy — Examines the inside of the body using a lighted, flexible instrument called an endoscope. This includes colonoscopy — a screening specific to the colon and rectum.
  • GI Motility Testing — Diagnoses motility (movement) disorders of the esophagus using tests performed in the GI Manometry Lab.

Screening Exams

Screening exams may be done to check for GI diseases such as: 

The Gastroenterology Program also conducts screening exams for cancer of the esophagus, colon and rectum

Biopsies of the Gastrointestinal Tract

A biopsy is a procedure in which small pieces of tissue are removed for testing in a laboratory to see if abnormalities are present. A tissue sample may be obtained with a needle using endoscopy and ultrasound or CT guidance. A cytologic brushing is a technique to scrape and gather cells to provide a biopsy sample.
