Prepared by residents and chief residents with senior faculty advisors at the Washington University School of Medicine, this handbook is an updated, easily accessible quick reference for handling everyday problems encountered in gastroenterology. It covers both inpatient and outpatient approaches with the same front-lines practicality as the world-famous Washington Manual® of Medical Therapeutics. The first section covers common symptoms, signs, and laboratory abnormalities; the second section focuses on specific diseases. Chapters are structured to help the clinician develop a logical, systematic approach to these common problems. Key points about the diagnosis and management of disorders are bulleted for easy reference. This edition also includes illustrations.
