Type 1 Dolichocolon as a Potential Anatomic Co-morbidity in Children with Perianal Crohn’s Disease

Rectosigmoid 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.
