Pediatric surgery or paediatric surgery is a subspecialty of surgery involving the surgery of fetuses, infants, children, adolescents, and young adults.
Many pediatric surgeons practice at children's hospitals. Pediatric surgeons have completed a general surgery residency (medicine), then complete 2 years (or more according countries) of subspecialty fellowship training.
Pediatric surgery arose in the middle of the 20th century as the surgical care of birth defects required novel techniques and methods and became more commonly based at children's hospitals.
