At the Memorial Health Gastrointestinal Procedures Center, we proudly share our medical outcomes.

Any time you have an invasive medical procedure, there is a risk of complications. We follow proven standards of care to reduce the risk of complications. Those standards are listed in the first column of the table below. Click on each term to learn what it means. The next columns show how well Memorial Health University Medical Center and similar hospitals around the country provided those standards of care. A higher score is better.

Complications from Colonoscopy

The table below shows how often our colonoscopy patients had complications from the procedure. The first column lists a possible complication. Click on each term to learn what it means. The next columns show what percentage of colonoscopy patients at Memorial Health University Medical Center experienced this complication. The last column shows the national benchmark score so you can reference how we compare to similar hospitals around the country. A lower score is better.

Explanation of Outcomes Terms

Cecal Intubation Rate

The cecum is the very end of the colon. A highly skilled endoscopist knows how to reach the end of the cecum, but also knows when not to reach the cecum. It is not always safe to attempt to reach the end of the cecum, so this number should not be 100 percent, but it should be greater than 95 percent.

Withdrawal Time

This is the time it takes an endoscopist to remove the scope after reaching the end of the cecum. This is an indication of the thoroughness of the endoscopist. Research has shown that withdrawal times under six minutes are linked to a significantly higher number of missed polyps or other growths. Therefore, the withdrawal time should be greater than six minutes.

Adenoma Detection Rates

This refers to the percentage of screening colonoscopies where an adenomatous polyp is found. This should be greater than 15 percent in women over 50 and greater than 25 percent in men over 50. Higher detection rates have been linked to better colon prep, longer examinations, better colonic distension, and ultimately better colon cancer prevention.

Unplanned Perforation

This occurs when the scope unintentionally makes a small hole in the wall of the colon. This can lead to pain, distention, and infection.

Post-op Bleeding

It is not uncommon to have some bleeding from the rectum after colonoscopy. However, severe or prolonged bleeding is not a normal occurrence and may be a sign of a problem.


It is extremely rare for a patient to acquire a bacterial infection from colonoscopy. When standards are correctly followed, the rate of infection should be zero.


It is extremely rare for a patient to have complications that result in death after a colonoscopy. The rate of death should be zero.
