Q

Smoker with 10 years of GORD assoc w weight gain, dysphagia for few weeks
CT chest,
omeprazole,
lose weight and stop smoking, gastroscopy

A

GASTROSCOPY!!!

I am concerned about dysphagia. Gastroscopy would be good.

From health pathways
Oesophageal cancer - red flag
Dysphagia (new onset and/or progressive)

However, endoscopy is the investigation with the highest specificity for oesophagitis caused by GORD as it is able to differentiate between mucosal lesions caused by infective oesophagitis, peptic ulcer disease, malignancy and other abnormalities of the gut
