The right side of the colon seems to be the Achilles heel of colonoscopy because polyps there tend to be flat and harder to find, and we confer the least protection from later colon cancer in that zone.
A recent article summary in Journal Watch Gastroenterology concludes that when we see a right-sided colon polyp, we may have missed another, so we should go back and look again.
This provocative recommendation represents a major change in the way we normally perform colonoscopy. But the issue is, and always has been, how to identify and remove all polyps from the colon.

Christian Vaillancourt, MD and his colleagues recently published an article in the journal Annals of Emergency Medicine (2009;54:663-671) entitled “The Out-of-Hospital Validation of the Canadian C-Spine Rule by Paramedics.” This rule was originally developed for “clinical clearance” (e.g., without the use of x-rays) of persons with possible cervical spine fracture (broken neck) in alert and stable trauma patients by qualified persons (generally, emergency physicians) in a health care setting (such as an emergency department). This particular study found that paramedics can apply the Canadian C-Spine Rule reliably, without missing important cervical spine injuries.
The Rule, properly applied to an awake and alert injured person for which there is a concern for a cervical spine injury, provides the following direction:
1. If a person has a high-risk factor (age greater than or equal to 65 years; a dangerous mechanism of injury [a fall from an elevation greater than or equal to 3 feet; fall down 5 or more stairs; direct blow to top of head, such as a diving board accident; motor vehicle accident characterized by high speed, rollover or passenger ejection; motorized recreational vehicle accident; bicycle collision]; or numbness/tingling in an arm or leg), then neck immobilization and x-rays are indicated.
