not who you asked but the perforation is 3-5 per 10,000; cardiovascular issues is 52 per 10,000, polyp removal carries risks of bleeding or perforation, and underlying patient physiology.
RESULTS Among the 30,818 records identified, 82 population-based studies from 24 countries were included, involving a total of 38.5 million colonoscopies. The estimated incidence per 10,000 colonoscopies was as follows: gastrointestinal AEs, including perforation (5.15; 95% confidence interval [CI] 4.19-6.34, I2 = 99%), bleeding (18.39; 95% CI 13.53-24.99, I2 = 100%), and splenic injury (0.61; 95% CI 0.43-0.85, I2 = 93%); nongastrointestinal AEs, including cardiovascular events (52.11; 95% CI 18.67-144.59, I2 = 100%), respiratory events (4.26; 95% CI 0.73-24.99, I2 = 100%), and deaths related to colonoscopy (0.18; 95% CI 0.10-0.34, I2 = 74%). Subgroup analyses yielded partially divergent findings. The majority of the included studies exhibited a low to moderate risk of bias.
just ask any AI, i don't got time to play tic-tac-toe with the NIH.gov website gating me behind click bus images for 10 minutes
You are hardly describing "serious complications" ('bleeding', and 'respiratory events' are very non specific, and the fact that this is an uncited meta-analysis across nations makes the whole enterprise suspect), even less so since your source averages 24 countries while we are speaking about US colonoscopy recommendations.
My source is not seeing one perforation each week at work.

These do not give reliable answers, as I am sure you know
What's your reference for this? That's incredibly (read, unbelievable) high for a routine procedure.
