Objectives The objective of this study was to determine whether the rates of abdominal pain or irritability, vomiting, and hematochezia differ depending on the duration of symptoms and age of the children with ileocolic intussusception. Methods We retrospectively investigated the charts of ileocolic intussusception children between January 2008 and December 2017 at a rural general hospital in Japan. Children were separated into 2 groups: the early visiting group, including children examined within 6 hours after onset, and the late visiting group, including children examined more than 6 hours after onset. We further separated them into 2 groups based on age: the infant group (age, <18 months) and the child group (age, ≥18 months). We compared clinical features, such as abdominal pain or irritability, vomiting, and hematochezia, between each group. Results Among 105 children with ileocolic intussusception, 51 were in the early visiting group and 49 were in the infant group. Hematochezia less frequently occurred in the early visiting group than in the late visiting group (29% vs 50%, P = 0.046). Furthermore, abdominal pain or irritability occurred less frequently in the infant group than in the child group (79.6% vs 98.2%, P = 0.003). Conversely, vomiting and hematochezia were more frequent in the infant group than in the child group (83.7% vs 51.8%, P < 0.001; 55.1% vs 26.8%, P = 0.005). Conclusions Clinical features of pediatric ileocolic intussusception may depend on symptom duration and age.
