Duodenal Ulcers (0)

When we speak of duodenal ulcers, we often imply that these are part of what is known as peptic ulcer disease; duodenal ulceration may be only rarely due to other conditions. Most duodenal ulcers are associated with a Helicobacter pylori infection, or the use of gastric irritating medications such as aspirin, non-steroidal anti-inflammatory drugs (NSAIDs), or bisphosphonates.

Duodenal ulcers are a common condition characterized by the presence of a well-demarcated break in the mucosa that may extend into the muscularis propria of the duodenum (see Images 1-3 or below). More than 95% of duodenal ulcers are found in the first part of the duodenum; most are less than 1 cm in diameter.
