24-hour and 30-day perioperative mortality in pediatric surgery

Multi-institutional analysis of 103,444 pediatric surgical cases (2012-2015) identified necrotizing enterocolitis as the diagnosis with highest 30-day mortality at 19%, with two-thirds of NEC deaths occurring within 24 hours. Overall perioperative mortality was 0.7%, demonstrating the need for large datasets to identify mortality patterns in pediatric surgery.
