A 28 year old lady presents with a 2-year history of mild dysphagia to both solids and liquids. She has no weight loss, but symptoms of heartburn and nocturnal cough. PPIs and bronchodilators haven’t helped. She is systemically well, and her examination is unremarkable. A “bird’s beak” appearance is noted on barium swallow. What is the most likely diagnosis? ``` Achalasia Benign stricture Plummer-Vinson syndrome Oesophageal spasm Stroke ```
Achalasia
89
A 76-year old retiree visits her GP with difficulty swallowing solids. She says this has been getting progressively worse over 1 month. There is no coughing, choking or heartburn. She reports food getting “stuck” 2-3 seconds after swallowing. She attributes her weight loss to not eating properly, and also thinks this has caused loose, brown-black stools. She feels tired. Bloods show a microcytic anaemia. Select the likely diagnosis: ``` Stroke Oesophageal cancer Pharyngeal pouch Plummer-Vinson syndrome Benign stricture ```
Oesophageal cancer Although appropriate age for a stroke, the dysphagia is to solids and progressive, suggesting a obstructive course, not functional one. This is supported by absence of cough or choking. Pharyngeal pouch or benign stricture would not be accompanied by weight loss, tiredness and IDA. Although Plummer Vinson may explain IDA, it wont account for melaena, it also would not typically be getting progressively worse. Given systemic symptoms and age, plus other red flag symptoms proceed on suspicion of oesophageal cancer.
