RESUMEN
BACKGROUND: The long-term effects of childhood surgery scars on health status, quality of life (QoL), self-esteem, and body image remain uncertain. This study explores these effects in school-aged children. METHODS: We conducted a retrospective cohort study involving 454 children (58% boys; 8-17 years) who had undergone surgical correction of anatomical anomalies or neonatal ECMO. Data included patient-reported scar perception and scar-related embarrassment, along with psychological assessment via questionnaires. RESULTS: About 34% of children rated their scars as 'nice-looking', 49% as 'indifferent', and 12% as 'rather ugly'. Most children (91%) never experienced scar-related embarrassment, while frequent embarrassment was reported by 3%. Surgical scar correction was desired by 6% of the 8-year-olds and 19% of the 17-year-olds. Scar perception did not significantly affect health status or QoL. However, negative scar perception was associated with lower self-esteem in girls and a more negative body image in boys. Girls were more likely to report negative scar perception (OR: 1.54, 95%-CI: 1.06-2.24) and scar-related embarrassment (OR: 4.29, 95%-CI: 1.77-10.44). CONCLUSION: Children who underwent surgery in the neonatal period and subsequently grew up with scars resulting thereof, mostly perceive them either indifferently or positively, with minimal effect on health status and QoL. Nonetheless, some children, particularly girls, experienced negative perceptions of their scars, although scar-related embarrassment was rare. We recommend integrating scar assessment into routine follow-up at ages 12 and 17, and offering appropriate and timely guidance and support to children at risk for negative effects of scars.
