Chairman of the Alder Hey Children's NHS Foundation Trust, Sir David Henshaw, said there was "no evidence that patients have been harmed as a result of issues identified in the report".
Sir David said:
We are confident that we are providing a safe service for our children and young people.
Theatres by nature are highly stressful, demanding working environments and we are aware that there have been difficulties within this department for some time.
Over the past year, we have undertaken a range of measures to address concerns from staff and make improvements.
