The operating room at Denver's Veterans Affairs Medical Center has been temporarily closed for specialized cleaning.

9Wants to Know has learned that residue was found on some of the surgical instruments. The VA says the decision to cancel all surgeries is out of an abundance of caution.

A residue was found on some surgical instruments during a routine inspection late last month. Surgeries continued without using the affected instruments while they were sanitized.

The decision was then made to complete specialized cleaning of all the instruments.

The VA says patient care has not been compromised.
