Few studies address the development of minor complications after screening or surveillance colonoscopy.
Dr Cynthia Ko and colleagues from Georgia the incidence of new symptoms after colonoscopy in previously asymptomatic people.
The research team also evaluated risk factors for symptoms, and patients' perceptions of this examination.
|94% lost about 2 days from normal activities post colonoscopy|
Patients completed a standardized interview at 7 and 30 days after colonoscopy.
A total of 502 patients aged 40 years and older underwent colonoscopy.
The patients underwent colonoscopy for colorectal cancer screening, surveillance, or follow-up of another abnormal screening test result.
Patients were excluded if they had a history of inflammatory bowel disease, visible gastrointestinal bleeding, or anemia.
The researchers found that minor complications occurred in 34% of subjects before day 7 and in 6% subjects between day 7 and day 30.
The complications were most commonly bloating and abdominal pain.
The team noted that 6 subjects had unexpected emergency department visits or hospitalizations within 30 days, including 2 with postpolypectomy bleeding.
On further analysis, the researchers observed that minor complications were more common in women.
The research team noted that minor complications were more common when the procedure lasted 20 minutes or longer.
Bowel preparation was rated the most difficult part of the examination for 77%.
The team found that 94% of subjects lost 2 or fewer days from normal activities for the colonoscopy itself, preparation, or recovery.
Dr Ko's team concluded, “Minor complications were common after screening and surveillance colonoscopy.”
“The bowel preparation was the most difficult part of the examination for most patients.”
“Most subjects lost 2 or fewer days from normal activities because of colonoscopy.”
