Purpose This study investigated the clinical characteristics, anatomical distribution, operative management, and postoperative outcomes of pediatric patients who underwent surgery for intestinal duplication and were registered through a nationwide multicenter survey conducted by the Korean Association of Pediatric Surgeons (KAPS).
Methods KAPS conducted a nationwide multicenter retrospective survey across 18 institutions between 2020 and 2024 and collected data from 144 patients.
Results Female patients accounted for 55.6% of surgically treated cases, corresponding to a male to female ratio of 1:1.25. Vomiting and abdominal pain were the most common presenting symptoms. Prenatal diagnosis was achieved in 43.7% of cases. The ileum was the most common site of intestinal duplication (41.0%). Cystic duplications predominated (82.6%), and communication with the native bowel was documented in 19.4% of cases. Elective surgery was performed in 83.3% of patients, with laparoscopic-assisted surgery being the most commonly used approach (52.8%). The most frequently performed surgical procedures were excision (49.3%) and bowel resection with anastomosis (47.2%). Recurrence occurred in three patients (2.1%), and mortality was reported in one patient (0.7%).
Conclusion This study represents the largest multicenter dataset on intestinal duplication in South Korea and provides comprehensive information regarding its clinical characteristics and surgical outcomes. These findings may serve as a useful reference for understanding the clinical spectrum and operative management of pediatric intestinal duplication in South Korea and may support the development of future standardized prospective studies.
Since the first introduction of robotic surgery systems in Korea in 2005, there has been a gradual increase in the number of robotic surgeries performed. However, robotic liver resection is one of the most complex procedures, and its application, especially to children, is still limited. Therefore, in this study, we aim to present our experiences with 2 pediatric patients who underwent robotic liver resection in Asan Medical Center and discuss the safety and feasibility of robot-assisted hepatectomy in pediatrics.
