Barium Studies in Meckel Diverticulum-Reply

Reply To the Editor.—Our report on the efficacy of barium in the diagnosis of bleeding Meckel diverticulum (Arch Surg108:361, 1974) was based on retrospective examination of records and radiographs of patients of many physicians. One can always find inadequacies when no prearranged protocol has been utilized.
