The Pediatric Surgery and Pediatric Trauma Division provides expert surgical care to infants and children with complex and rare gastrointestinal disorders or chest malformations. These include congenital lung malformations; which involve a narrowing or absence of a portion of the esophagus, bile ducts or intestines, called atresia; and other gastrointestinal abnormalities of the colon, trachea and anus. Physicians also plan corrective procedures for infants with neonatal congenital abnormalities while they are still in the womb. The division’s endosurgery program utilizes laparoscopic and thoracoscopic techniques in pediatric procedures. The division conducts clinical research on Russell-Silver syndrome and other disorders, and investigates topics such as intra-abdominal fluid as a diagnostic indicator for intestinal and biliary injuries in children.
