Recent studies in adults indicate a role for dolichocolon in constipation and disorders of gut\u2010brain interaction. Contrast enema (CE) imaging is commonly used to identify DC, typically defined as a sigmoid colon extending above, or a transverse colon descending below, the iliac crest line. Despite its potential relevance, the prevalence and clinical significance of DC in pediatric gastroenterology remain poorly understood.<\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>Methods<\/jats:title>\n                    <jats:p>This retrospective study assessed the prevalence of DC in pediatric patients presenting with constipation and related gastrointestinal symptoms. A total of 155 contrast enemas from pediatric gastroenterology patients meeting predefined inclusion criteria were reviewed. Three blinded pediatric gastroenterologists independently evaluated each CE for features of colonic redundancy consistent with dolichocolon, based on a priori imaging criteria.<\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>Results<\/jats:title>\n                    <jats:p>Consensus\u2010based identification (i.e., independent agreement among all three reviewers) of DC was observed in 74.1% of children under 2 years old and 88.6% of those aged 2\u20134 years presenting with constipation. The prevalence significantly decreased with age, with 68.8% in children aged 5\u201310 years and 47.6% in adolescents aged 11\u201317 years.<\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>Conclusions<\/jats:title>\n                    <jats:p>These findings suggest that dolichocolon is common in pediatric patients with constipation and relatable symptoms, particularly in early childhood.
