[Endoscopy in upper gastrointestinal tract hemorrhage].
There are several changes in the role that endoscopy plays in upper gastrointestinal hemorrhage. We propose indications and make point about the factors than an endoscopist must have in mind referring to timing the endoscopy study. In the experience of our Hospital (Hospital Central Norte de Petroleos Mexicanos, Mexico City), during 20 years we found a diminution in the prevalence of duodenal ulceration and an increase in gastric ulceration, erosive gastritis an neoplasies as causes of upper gastrointestinal hemorrhage.
