It wasn't all bad
Ryan, 9, has undergone eight surgeries over the course of his life, and during each one, he's been accompanied by his favorite stuffed animal, Mike Wazowski from Monsters, Inc.
Ryan has several health issues, and Mike brings him comfort during hospital stays. Before Ryan's last operation, his urologist at Children's Hospital of Wisconsin, Dr. Travis Groth, thought Mike looked worn out, and decided he needed to have surgery, too. Groth had his surgical team come into Ryan's room, where he identified Mike as the patient. Groth then got to work, suturing Mike's arm and making Ryan's day. A spokesperson from Children's Hospital of Wisconsin told People both patients are "recovering well at home."
