Abstract
PURPOSE: Spontaneous gastrointestinal perforations (SGIPs; not associated with injury or disease) occur rarely in pediatric patients. This study aimed to define age-specific features associated with SGIPs in pediatric patients. METHODS: Retrospectively reviewed the clinical data of children (before adolescence) who received surgery due to a SGIP at a single institution. Thirty-nine patients were enrolled. Characteristics were compared between the 2 age groups: neonates (group A) and beyond neonates (group B). RESULTS: Group A included 24 patients (61.5%) an group B included 15 patients (38.5%). Thirteen perforations occurred in the stomach (33.3%), 12 in the small intestine (30.8%), and 14 in the large intestine (35.9%). A significantly higher proportion of perforations occurred in the stomach and small intestine in group A, while more perforations occurred in the large intestine in group B (P = 0.01). Several associated conditions during the preoperative period were identified in both groups. The overall mortality rate was 15.4% (6 of 39). Mortality was relatively high in group A (5 of 24, 20.8%) and for perforations of stomach (3 of 13, 23.1%) and small intestine (3 of 12, 25.0%); however, there were no significant differences with regard to age or perforation site (P = 0.244, P = 0.122, respectively). CONCLUSION: SGIPs in pediatric patients had diverse clinical features and different perforation patterns according to age group. However, no significant group differences in mortality were found. Thus, favorable results regardless of age can be expected with prompt recognition, medical resuscitation, and adequate surgical management.
