In brief: Colon perforation

The most feared complication of a colonoscopy or colon biopsy is the risk of perforation--inadvertently cutting through the entire thickness of the bowel wall.
This complication used to occur in about 1 in 1000 persons undergoing the procedure. With improved techniques and instruments, the risk is now about 1 in 5000.
