Dolichocolon is common in pediatric gastroenterology patients with constipation and associated complaints.
Article in Journal of pediatric gastroenterology and nutrition, 2026. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 6 papers.
What it found
Each row is one number read from the abstract, on the scale the paper reported it, with its interval. Left of the dashed line favours the treatment, right favours the comparator. Under each row is the sentence it came from. New to these charts? A ten-minute tutorial.
The abstract states no effect estimate the extractor could read, or names no intervention and outcome on the map, so this paper lights no cell and moves no belief. It is still indexed, cited and linked below.
The trial behind it
Trials whose registry record cites this paper, or whose number appears in the abstract. A trial that started after this paper was published is citing it as background, not reporting it.
Neither the registry nor the abstract names a trial number. If this is a trial report, that itself is worth knowing.

Abstract
objectivesDolichocolon (DC), classified under International Classification of Diseases, Tenth Revision (ICD-10) code Q43.8 ("Other specified congenital malformations of intestine"), refers to an elongated or redundant large intestine. Recent studies in adults indicate a role for dolichocolon in constipation and disorders of gut-brain 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.
methodsThis 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.
resultsConsensus-based 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 2-4 years presenting with constipation. The prevalence significantly decreased with age, with 68.8% in children aged 5-10 years and 47.6% in adolescents aged 11-17 years.
conclusionsThese findings suggest that dolichocolon is common in pediatric patients with constipation and relatable symptoms, particularly in early childhood. Further research is warranted to clarify its clinical implications and potential role in pediatric gastrointestinal disorders.
