Colonoscopy and Laparoscopy

Colonoscopy may be ordered if there is reason to suspect primary colorectal cancer or if you have had colon cancer in the past. A colonoscope is a highly flexible instrument used to examine the entire length of the colon. The instrument is a tiny viewing camera that gives off light and allows the physician to see inside the patient's colon. Occasionally, during colonoscopy, a small tissue sample will be obtained for laboratory analysis (called a biopsy).

Laparoscopy is similar to colonoscopy except that it uses an instrument called a laparoscope. Unlike colonoscopy, most patients undergoing laparoscopy will require a general anesthetic. Like the colonoscope, it is a viewing camera that also emits light. The laparoscope is a small tube-like device used primarily for examining the liver and pancreas. For this test, a small cut is made in the abdomen to insert the instrument. The surgeon may use this opportunity to perform a biopsy.
