Our Services

Diagnostics & Screenings
We utilize a comprehensive array of techniques to evaluate the health of the gastrointestinal tract (GI).  The GI tract begins with the mouth, where food is eaten, and continues through the digestive system to the esophagus, the stomach, the small intestine, the large intestine or colon, and the rectum.  Other organs associated with the GI system include the liver, pancreas and gallbladder.  Some of the most common disorders that we evaluate and treat include:

  • Stomach Disorders including ulcers, heartburn and reflux.
  • Intestinal Disorders including colitis, colon cancer and irritable bowel syndrome.
  • Liver Disorders including hepatitis, cirrhosis and hemochromatosis.

Outpatient diagnostic services include:

  • Colonoscopy. A longer flexible tube is used to visualize the entire colon, remove polyps, and diagnose colon cancer.
  • Endoscopy. A thin, flexible tube called an endoscope is inserted through the mouth and esophagus into the upper GI tract.  It is used to view the interior of the stomach and small intestine to detect abnormalities and obtain tissue samples for analysis.  
  • Flexible Sigmoidoscopy. A thin, flexible tube called a sigmoidoscope is inserted into the anus to examine the lining of the rectum and colon.  It is used to diagnose diarrhea or rectal bleeding. 
  • Routine Colon Cancer Screening. Colorectal cancer is the second leading cause of cancer deaths, 55,000 persons per year.  Peninsula Gastroenterology supports the recommendation of the American Cancer Society that persons fifty and over and those with a family history of colorectal cancer should receive regular screenings.  Early detection can prevent or cure cancer.   Removing pre-cancerous growths, called polyps prevents colon cancer.  Polyps are a precursor to colon cancer in 80% of cases.

Routine cancer screenings include:

  • Fecal Occult Blood Tests. A diagnostic test used to examine a small sample of stool to determine the presence of blood.
  • Flexible Sigmoidoscopy. A diagnostic test used to visualize the rectum and a portion of the colon for abnormalities, such as polyps.
  • Colonoscopy. A diagnostic test used to visualize the entire colon to remove polyps and diagnose colon cancer.  This is the recommended test for colon cancer screening, as it is most sensitive and specific.
