Comparison of clinical manifestations and immunoreactivities of Meckel's diverticulum with and without gastric heteroplasia

Heterotopic mucosa defines distinct MD subtypes, each with characteristic clinical presentations. Despite its specificity limitations, technetium-99m pertechnetate scintigraphy is optimal for evaluating patients with gastrointestinal bleeding, whereas ultrasound demonstrates poor sensitivity. These findings support the adoption of tailored diagnostic strategies and advocate for universal resection in children with symptomatic MD.
