A good surgical operation is conceived in an understanding of the origin and method of dissemination of the disease. It is an attack that is well planned with knowledge of the anatomy involved and with the expectation of a morbidity and mortality reasonably small in relation to the relief that ensues.

In the light of new contributions to the knowledge of both normal and pathologic anatomy and physiology, one must at intervals revaluate one's surgical procedures. In so doing one learns why methods once thought to be theoretically sound have proved unsatisfactory in practice, and one may plan for the future on a more certain basis of fact.
