An unexpected giant: incidental discovery of a giant Meckel's diverticulum during appendectomy.

Giant Meckel's diverticula (GMD), characterized by a diameter over 5 cm, are a rare manifestation of the most common congenital gastrointestinal anomaly. GMDs challenge the conventional understanding of Meckel's diverticulum. Their detection may be linked to complications such as inflammation, perforation, or obstruction, which are more frequent in larger lesions. This report presents an unusual case of GMD found incidentally during surgery for acute appendicitis, representing the first documented instance in the English-speaking Caribbean. It emphasizes the diagnostic difficulties associated with these lesions, the possibility of additional pathology, and the reason for surgical removal, even when they are discovered incidentally.
