Abstract
A duodenal ulcer is disruption of the mucosal integrity of the duodenum leading to a submucosal exposure. The endoscopic findings of duodenal ulcers can be classified into active, healing, and scarring stage. Complications of duodenal ulcer include bleeding, perforation, and stricture. The most common complication is a bleeding ulcer which can be divided into type I, type II, and type III according to the Forrest classification. The second most common complication related to duodenal ulcer is perforation. A fixed obstruction can occur because of the scar and followed by distortion of structures. Duodenitis is inflammation of the duodenum. Endoscopic findings are erosions, erythema, and/or edema of duodenal mucosa.
