Esofagograma: imágenes que valen más que mil palabras.

The study of esophageal diseases requires multiple diagnostic tests since no one test alone can provide full information on upper digestive tract anatomy and functionality. For general surgeons and gastrointestinal surgeons, the esophagogram is an essential tool that can suggest a diagnosis while simultaneously providing an idea of the anatomy of the organ and outlining an easily evaluated map without the need of a radiologist. This information can be used to establish a surgical plan. The aim of this article is to show readers the usefulness of esophagograms at referral centers for study and treatment of esophageal diseases while providing representations of several frequent diseases.
