Recent personal reflection brings to mind that, shortly, almost a half century will have passed since the publication of the first edition of Principles of Surgery. In that initial iteration of the textbook, which has been updated periodically and maintains its popularity, many scientific facts and definitive protocols for management of medical disorders were presented. Prior to that publication, it had been stressed that the appearance of a statement in print does not assure immutability or absolute truth. C. Sidney Burwell, Professor of Medicine at Vanderbilt stated, “My students are dismayed when I say to them, ‘Half of what you are taught as medical students will in ten years have been shown to be wrong, and the trouble is, none of your teachers knows which half.’” The stated truism persists.
