Background The treatment of high-grade (III/IV/V) blunt pancreatic injuries remains controversial. The study aims to summarize and evaluate nonresection management of the pancreas for grade III and IV blunt pancreatic injuries in children. Methods Twenty children [6.9 (3–12) years] treated at our center between January 2010 and June 2018 were included in this study. Their medical records and the outpatient follow-up data within 12 weeks after discharge were retrospectively reviewed. Long-term follow-up was conducted by telephone in February 2020. Results Nine children developed complications, including 8 pancreatic pseudocysts and 1 abdominal infection, after treatment at external hospitals and were transferred to our center with an average length of stay of 33.8 (8–63) days. Eleven children were admitted to our hospital directly after injury, with an average length of stay of 47.5 (23–69) days. One child underwent emergency laparotomy for hemorrhagic shock and Roux-en-Y drainage of the distal pancreas. The remaining 10 children received conservative treatment: 7 developed pancreatic pseudocysts, 2 developed abdominal infections, and 1 recovered uneventfully. For children with pancreatic pseudocysts (15/20, 75.0%), 4 recovered after conservative treatment, 4 recovered after percutaneous puncture, 5 recovered after external drainage of the cyst, and 2 recovered after alimentary tract anastomosis. Three children (3/20, 15.0%) who developed abdominal infection recovered after abdominal irrigation and drainage. No child was admitted to the ICU or died. Four children (4/20, 20.0%) developed local pancreatic atrophy within 12 weeks after discharge, but no other long-term complications were observed. Conclusions Nonresection management of the pancreas could be a feasible option for children with grade III and IV blunt pancreatic injuries. Regular long-term follow-up is essential in terms of pancreatic function, especially in patients with pancreatic atrophy.
