FOREWORD
One doesnt discover new lands without consenting to lose sight of the shore for a very long time.
Andre Gide
As you set out for Ithaka
hope the voyage is a long one,
full of adventure, full of discovery
And if you find her poor, Ithaka wont have fooled you.
Wise as you will have become, so full of experience,
you will have understood by then what these Ithakas mean.
C. P. Cavafy
To be a surgeon is to dedicate ones life in the service of others through the application of acquired clinical wisdom in the broad domains of repair, reconstruction, and replacement. It means learning to use ones mind and ones hands and of interacting with others in new ways so as to meet the challenges that face our patients each and every day to the best of our ability. It means that while at times a surgeon may be an anatomist, physiologist, pathologist, or internist, as the leader of a surgical team, whether in the operating room or on the floor, surgeons must always see with their mind, as well as their eyes.
For over a century, a foundation of excellence in the Department of Surgery at Beth Israel Deaconess Medical Center has been nurtured and sustained by a variety of outstanding leaders of Harvard Medical School. Written by the surgical faculty and house staff of our department, this handbook is principally directed toward those students commencing their clinical work in the operating room, outpatient clinics, and surgical wards. It is intended as a vade mecum, which translated from the Latin means go with me, a handbook to be carried at all times.
The emphasis of this handbook is to provide students with a critical summary of broad anatomic, physiologic, and pathologic principles that form the framework for surgical decision-making. The intent of this handbook is not to provide facts to be memorized, but a guide to better understand a select number of common problems, diagnostic approaches, and those operative interventions that can be called upon to cure or to relieve suffering. Building upon this initial foundation, we believe that future leaders in American medicine will be best able to challenge currently accepted truths, through their creativity, original thought, and innovations.

PREFACE
Pocket Surgery is the go to resource for medical students and Surgery house staff. The bulleted format gets the information usually found in a two-volume surgery textbook into one loose leaf notebook small enough to fit into your white coat pocket. Pocket Surgery, Second Edition builds on the success of the first edition. With this release we have updated content and added more illustrations. Every chapter has been written by surgery residents and fellows and coauthored by experts in the field. The goal is to make sure medical students excel in their surgery clerkship rotation and surgery shelf exam. Interns and junior surgery residents will appreciate having outlines for relevant facts, medication doses, and management algorithms. Residents will also find
