Anna was transferred from St Mary's Hospital to Great Ormond Street for a surgical procedure known as a "Kasai procedure", which if successful, slows down liver degeneration and delays the need for a liver transplant, which was vital in 1993 when paediatric liver transplants were relative new although fast developing, and the longer a transplant could be delayed, the better the potential success rate.

Anna was transferred at the age of exactly 8 weeks old, which was the last day that such a procedure can be undertaken due to the difficulty in firmly diagnosing Anna's condition.

The surgery was a success; it was so successful that when Anna had her liver transplant almost 2 years later, the transplant surgeon said it was the best Kasai procedure he has ever seen, and aided their surgery considerably.
