Transabdominal ultrasonography is increasingly used as a novel modality for detecting pediatric functional constipation (FC). This systematic review and metaanalysis aimed to assess the diagnostic parameters of FC including rectal diameter (RD) and anterior rectal wall thickness. A systematic search was conducted of the Ovid MEDLINE, Embase, Scopus, and PubMed databases through September 29, 2023, to identify studies comparing RD...

Question: What causes childhood constipation, and what can predict organic constipation?
Finding: Constipation represents 14.7% of gastroenterology visits. Functional constipation is more common among constipation types, while organic constipation is more common in young children and those with a low body weight, stunted growth, mucus in the stool, and associated diseases.
Meaning: Younger children and those with lower growth or mucus in the stool should be assessed for underlying organic causes of constipation.

Purpose : In most instances, constipation is considered as idiopathic or functional. The total colonic transit time, traced by radio-opaque markers, makes possible the identification of the colon segment that has the motility alteration that causes constipation. We measured the total and segmental colonic transit time in children with chronic idiopathic constipation and compared the results with those without constipation...
