Type 1 Dolichocolon as a Potential Anatomic Co-morbidity in Children with Perianal Crohn's Disease.
Article in Digestive diseases and sciences, 2026. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 2 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
backgroundPerianal Crohn's disease (PCD) represents one of the most severe and refractory forms of pediatric inflammatory bowel disease (IBD). Constipation and colonic redundancy, particularly type 1 dolichocolon (T1-DC), may increase distal rectosigmoid pressure, and exacerbate perianal pathology. We hypothesized that T1-DC is more common in children with PCD than in those with uncomplicated ileocolonic Crohn's disease (CD) or non-IBD controls.
methodsRetrospective electronic medical record search was performed. DC type was determined radiographically using established criteria, focusing on T1- and T2-DC. Constipation history was abstracted from medical records under IRB-approved protocols.
resultsTwenty consecutive children with PCD [penetrating (B3p) or inflammatory (B1p)] were compared to 20 children with non-complicated ileocolonic CD (L3/B1) and 30 non-IBD trauma controls. DC was significantly more prevalent in PCD than in ileocolonic CD or controls (p < 0.001), primarily due to T1-DC. The associations persisted (p < 0.03) in PCD patients without a history of constipation.
conclusionsRectosigmoid redundancy (T1-DC) may represent an underrecognized anatomic co-morbidity in children with PCD, contributing to increased distal pressure and susceptibility to perianal complications. Identification of T1-DC could inform surgical decision-making and postoperative management. Targeted approaches-such as segmental resection during stoma reversal, structured bowel regimens, physical activity, and pelvic-floor biofeedback-may help reduce recurrence risk. Prospective studies are needed to define the mechanistic role of colonic redundancy in the pathogenesis of PCD.
