Which of the following statements are correct regarding Barrett's oesophagus? 1. It is a metaplastic change. 2. It is a risk factor for development of adenocarcinoma. 3. Ingestion of NSAIDs is the aetiological factor for its development. 4. Endoscopic mucosal resection is an effective treatment. Select the answer using the code given below.
Barrett's oesophagus is a condition where the lining of the food pipe (oesophagus) changes. We will examine each statement to determine their accuracy.
This statement is correct. Barrett's oesophagus is characterised by the replacement of the normal flat lining cells (squamous epithelium) of the lower oesophagus with a different type of cell (columnar epithelium). This change from one mature cell type to another is known as metaplasia.
This statement is correct. Having Barrett's oesophagus increases the risk of developing a type of cancer called oesophageal adenocarcinoma in the lower part of the food pipe. This is a significant clinical concern associated with the condition.
This statement is incorrect. The main cause (aetiological factor) of Barrett's oesophagus is long-term exposure to stomach acid due to acid reflux or GERD (Gastroesophageal Reflux Disease). While Non-Steroidal Anti-Inflammatory Drugs (NSAIDs) can sometimes worsen reflux symptoms, they are not the primary cause of the metaplastic changes seen in Barrett's oesophagus.
This statement is correct. For specific cases, particularly those involving high-grade dysplasia or very early cancer within the Barrett's segment, treatments like Endoscopic Mucosal Resection (EMR) can be effective. EMR is a procedure used to remove abnormal tissue from the digestive tract lining.
Based on the analysis:
The combination of correct statements is 1, 2, and 4.
An air fluid level with dilated oesophagus and "bird beak" appearance in a barium swallow is diagnostic of:
