Clinical characteristics and surgical outcomes of intestinal duplication in South Korean children: a nationwide multicenter retrospective case series

초록

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.
