Two Contrasting Scintigraphy‐Negative Pediatric Meckel's Diverticula Identified and Localized by Intestinal Ultrasound and Double‐Balloon Enteroscopy: A Report of Two Cases

open access: yesDEN Open, Volume 7, Issue 1, April 2027.
ABSTRACT Scintigraphy‐negative Meckel's diverticulum (MD) is diagnostically challenging in children, particularly when the underlying pathology differs between cases. Technetium‐99m pertechnetate scintigraphy is widely used for diagnosis; however, false‐negative results may occur when ectopic gastric mucosa is absent or when the diverticulum is ...
