|Abstract:||Meckel's diverticulum is the most common congenital gastrointestinal anomaly. 99m Technetium pertechnetate imaging (Meckel's scan) is the best noninvasive method used to diagnose this condition when heterotopic gastric mucosa (HGM) is present. Although cimetidine enhancement has been shown to improve sensitivity of the Meckel's scan, ranitidine enhancement has also been advocated; however, this recommendation is based on unpublished data. Thirty-seven children with confirmed Meckel's diverticulum were reviewed retrospectively. Of eight children with HGM in the Meckel's diverticulum who presented with profuse rectal bleeding and underwent the conventional Meckel's scan, three of them (37.5%) had a false negative study. Ranitidine, when administered either intravenously or orally for 24 h prior to the Meckel's scan, enhanced the sensitivity of this test to 87.5% in our patient cohort.|
