case_images: EGD (Figure 1). Endoscopic evaluation of the esophagus revealed mild, circumferential, and shallow irregularities in the esophageal mucosa (Figure 1(a)). The gastric mucosa had a diffuse patchy erythema with white-colored mucosa noted in the fundus and pyloric antrum (Figure 1(b)). The 5 mm diameter opening of the stricture prevented further passage of the scope (Figure 1(c)).
case_images: Contrast radiography (a) and fluoroscopy (b) of the proximal duodenal stricture.
