Final answer:
During an EGD, a patient with dysphagia could have various esophageal abnormalities such as a stricture or hiatal hernia. Dysphagia suggests difficulty in swallowing, and a stricture, which is a narrowing of the esophagus, is a common finding.
Step-by-step explanation:
When conducting an Esophagogastroduodenoscopy (EGD) on a patient with dysphagia, various findings could be present. Dysphagia refers to difficulty in swallowing, and during an EGD, a camera is used to visualize the upper gastrointestinal (GI) tract. One might find a normal esophagus where no abnormalities are detected, suggesting dysphagia may have a functional or neurological cause. Alternatively, there can be punched-out lesions, indicative of conditions like esophageal ulcers or severe esophagitis. Another potential finding is an esophageal stricture, a narrowing of the esophagus that could be due to scarring from acid reflux or other causes. Lastly, a hiatal hernia, where part of the stomach pushes up through the diaphragm into the chest, can be observed, which is a common cause of reflux symptoms, including dysphagia. Based on the detailed information discussed, option 3, a stricture in the esophagus, is a common finding during an EGD in patients with dysphagia.
