A pediatric surgeon is a doctor who operates on patients from before birth through adolescence, treating everything from birth defects and childhood cancers to emergency injuries and common conditions like appendicitis. Unlike adult surgeons, pediatric surgeons train specifically to work on bodies that are still growing, using smaller instruments and techniques adapted for infants, children, and teens. The U.S. Bureau of Labor Statistics defines their scope as diagnosing and performing surgery on fetuses, premature and newborn infants, children, and adolescents.
What Pediatric Surgeons Treat
The range of conditions is broad. On any given day, a pediatric surgeon might remove a child’s appendix, repair a hernia in a toddler, or operate on a newborn whose organs didn’t form correctly in the womb. Some of the most common procedures include appendectomies (removing the appendix through small incisions), gallbladder removal, and pyloromyotomy, which fixes a thickened stomach muscle that prevents newborns from keeping food down.
Other routine surgeries include repairing hydroceles (fluid buildup in the scrotum), placing ports for children undergoing chemotherapy, performing biopsies on swollen lymph nodes, removing the spleen, and correcting tongue-tie in infants who have trouble feeding. Pediatric surgeons also perform fundoplication, a procedure that wraps the stomach around the lower esophagus to stop severe acid reflux in children who don’t respond to medication.
What sets this specialty apart from adult surgery is the newborn and fetal work. Pediatric surgeons are often the first doctors called when a baby is born with a serious structural problem.
Newborn and Fetal Surgery
Some of the most complex cases involve congenital anomalies, structural problems that develop before birth. These include gastroschisis, where a baby’s intestines push through an opening in the abdominal wall, and omphalocele, a similar condition where organs protrude through the belly button area. Both require surgical repair shortly after delivery.
Pediatric surgeons also correct problems with the digestive tract that block food from passing through. Duodenal atresia, for instance, is a blockage in the first part of the small intestine. Biliary atresia affects the bile ducts connecting the liver to the intestine. Hirschsprung’s disease, where nerve cells are missing from part of the colon, causes severe constipation and requires removing the affected section of bowel. Tracheoesophageal fistula, an abnormal connection between the windpipe and esophagus, needs repair within the first days of life so the baby can eat and breathe safely.
Some conditions are detected on prenatal ultrasound, giving the surgical team time to plan. In rare cases, surgeons can even intervene before birth through fetal surgery. Congenital lung masses, chest wall deformities like pectus excavatum (a sunken breastbone), and sacrococcygeal teratomas (tumors at the base of the spine) all fall within the pediatric surgeon’s territory.
Subspecialties Within Pediatric Surgery
Pediatric surgery itself is already a subspecialty of general surgery, but many pediatric surgeons narrow their focus even further. The major areas of concentration include:
- Neonatal surgery: operating on premature and newborn babies, often in the first hours of life
- Pediatric oncology surgery: removing tumors and performing biopsies in children with cancer
- Pediatric urology: correcting problems with the kidneys, bladder, and reproductive organs
- Pediatric trauma surgery: treating injuries from accidents, falls, and other emergencies
- Fetal medicine: intervening surgically before a baby is born
- Minimally invasive surgery: using small incisions and cameras (laparoscopy) to reduce recovery time
- Thoracic surgery: operating on the lungs, chest wall, and airway
- Hepatobiliary surgery: treating conditions of the liver, gallbladder, and bile ducts
At large children’s hospitals, you’ll find surgeons who spend most of their time in just one or two of these areas. At smaller hospitals, a single pediatric surgeon may handle the full range.
Training and Certification
Becoming a pediatric surgeon takes longer than almost any other medical career path. After four years of medical school, a doctor completes a five-year general surgery residency and must earn board certification in general surgery from the American Board of Surgery. Only then can they apply for a pediatric surgery fellowship.
The fellowship lasts two years, with a minimum of 96 weeks of progressive training at a program accredited by the ACGME (the organization that oversees graduate medical education in the U.S.) or its Canadian equivalent. Each year requires at least 48 weeks of full-time clinical work. After completing the fellowship, surgeons must pass both a qualifying exam and a certifying exam in pediatric surgery. They also need a full, unrestricted medical license and must stay current through a continuous certification program.
All told, a pediatric surgeon typically spends 13 to 15 years in education and training after high school: four years of college, four years of medical school, five years of general surgery residency, and two years of fellowship. That extended pipeline is one reason pediatric surgeons are relatively rare compared to other surgical specialists.
How Pediatric Surgery Differs From Adult Surgery
Children are not small adults. Their anatomy is different, their organs are still developing, and their bodies respond to anesthesia and blood loss differently. A newborn’s entire blood volume is roughly the amount in a coffee cup, which means even small amounts of bleeding during surgery require careful management.
Pediatric surgeons also think about long-term growth in a way adult surgeons don’t have to. A repair that works on a six-month-old needs to hold up as that child grows over the next 18 years. Scar tissue, for example, doesn’t stretch the way normal tissue does, so incision placement and surgical technique matter in ways unique to younger patients.
The communication demands are different too. A pediatric surgeon explains a diagnosis to worried parents while also keeping a frightened child calm. For adolescents, the surgeon balances respecting a teenager’s growing autonomy with keeping parents informed and involved in decisions.
