Colonoscopy

Colonoscopy is a safe, effective method of examining the lining of the colon and rectum using a long, flexible, tubular instrument. It is used to diagnose colon and rectum problems and perform biopsies and remove colon polyps, an important step in the prevention of colon cancer. More

Upper Endoscopy

An upper endoscopy is used to visually examine your upper digestive system with a tiny camera on the end of a long, flexible tube. A gastroenterologist uses endoscopy to diagnose and sometimes treat conditions that affect the esophagus, stomach and beginning of the small intestine. More

Flexible Sigmoidoscopy

Flexible sigmoidoscopy is a routine outpatient procedure in which the inner lining of the lower large intestine is examined. If growths or polyps are found during the procedure, a biopsy may be taken, or you may be advised to have a complete colon exam or colonoscopy. More

Pre-/Post-Procedure Guidelines

It is important to prepare properly for your colonscopy, upper endoscopy or flexible sigmoidoscopy. Learn the simple steps you should take before and after your procedure by contacting your physician's office. More
