Using California’s Ambulatory Services Databases, the authors identified 1.58 million surveillance/screening colonoscopies (2005-2011) and compared complications to patients who underwent other ambulatory procedures like joint aspiration, arthroscopy and cataract surgery.
- GI complications including perforation and GI bleeding were low but more common with colonoscopy than comparator procedures
- Rates of serious non-GI complications including myocardial infarction, stroke, and serious pulmonary events were no higher than other low-risk comparator procedures.
- Complication rates were higher with advancing age, particularly in those >70 years. see Figure 2 below
