case_images: The patient was intubated and underwent emergent endoscopy, during which the mothball was identified in the upper esophagus and was exerting a compressive effect on the trachea (Figure 1(a) and (b)). Post removal, endoscopic esophageal exploration with an OlympusTM GIF-160 endoscope demonstrated minimal mucosal erosions and no perforations (Figure 1(c)).

case_images: Repeat endoscopy identified a stricture in the proximal esophagus at the location where the mothball had come into contact with the mucosa (Figure 2(a)). The stricture was serially balloon dilatated (Figure 2(b)), and triamcinolone was injected into the four quadrants of the stricture area. A third endoscopy showed resolution of the stricture (Figure 2(c)).
