Dangers And Risks of Colonoscopy Procedures

It’s everyone’s worst nightmare to go in for a routine test only to find that he or she is now worse off than before, yet that’s exactly what happened at VA hospitals in Murfreesboro, Tennessee; Augusta, Georgia; and Miami, Florida. Out of 10,000 patients who had colon cancer screening, 6 veterans tested positive for HIV, 34 tested positive for hepatitis C and 13 tested positive for hepatitis B following their routine procedures. One could argue these people may have needed a hepatitis treatment prior to their colonoscopy treatments; that these were just isolated incidents. However, there are a few risks of colonoscopy procedures that should be discussed beforehand.

The most common side effect of colonoscopy procedures is nothing more than a little bloating and distension. Some patients feel lightheaded, fatigued or nauseous from the sedative. Cramping and abdominal pain are likely if any colon polyps were nicked off. Patients must have a chaperone and may not return to work, drive or operate heavy machinery following the exam. Many individuals say the worst part of the whole process is the colonoscopy prep, where they have to take medications intended to flush their system, leaving them in the bathroom constantly for nearly 8 hours.

In a 2005-2006 study, 110 patients in Chapel Hill, North Carolina were asked about the side effects from their colonoscopy procedures. Of the 110, 17% of the patients reported side effects from their screening colonoscopy process, which included abdominal pain, cramping, vomiting, lightheadedness, sharp pains in the right hip and fatigue. On average, people spent 21 hours prepping for the procedure, which involved 16.5 hours flushing their system, 0.8 hours traveling, 1.4 hours in the waiting room, 12 minutes undergoing sedation, 20 minutes for their colonoscopy procedure and 47 minutes of on-site recovery.

Because a colonoscopy is the golden standard of colon cancer prevention and there is a nation-wide drive to get more people screened for early detection, it is difficult to get an accurate figure on the risk of colonoscopy complications. According to ‘The Annals Of Internal Medicine,’ the rate of serious complications from the procedure is “10 times higher than for any other commonly used cancer-screening test.” In 2006, a CDC-funded study found that 1 in 200 people who had a procedure that involved cancer removal put them in the hospital. In routine procedures where no colon polyps were removed, just 1/1,000 had a serious complication, while patients getting biopsies had 7/1,000 colonoscopy complications like bleeding or perforations.
