Study Notes
Esophageal Wall Compression
- Esophageal wall compression can occur due to nearby inflammatory or neoplastic processes.
- The compression can lead to dysphagia, and the best diagnostic tool is a barium swallow (X-ray).
Achalasia
- Achalasia is a motor disorder characterized by the lack of progressive peristalsis movement and incomplete relaxation of the lower esophageal sphincter.
- This prevents the passage of food to the stomach and is often idiopathic, but secondary causes include Chagaz disease.
- Complications of achalasia include GERD and a 5% risk of developing squamous cell carcinoma.
Esophagitis
- Esophagitis is a condition where the esophageal mucosa is inflamed, often due to Candida infection, especially in immunosuppressed patients.
- Candida esophagitis is associated with immunosuppression, prolonged steroid intake, uncontrolled diabetes, and HIV.
Reflux Esophagitis (GERD)
- Reflux esophagitis occurs when acidic gastric contents reflux into the lower esophagus, causing mucosal injury.
- Clinically, it is referred to as GERD (gastroesophageal reflux disease).
Helicobacter pylori
- H. pylori organisms are Gram-negative, helical, or spiral-shaped, and flagellate.
- They can cause gastric mucosal injury, leading to dyspepsia, and are a major risk factor for peptic ulcer disease and gastric cancer.
Diagnosis of H. pylori
- Non-invasive tests for H. pylori diagnosis include urea breath tests, stool antigen tests, and serological tests.
Sister Mary Joseph Nodule
- A Sister Mary Joseph nodule is a metastatic lesion in the umbilicus, often indicating gastric cancer.
Other Primary Gastric Tumors
- Gastric lymphomas represent 5% of all gastric malignancies, with the stomach being the most common site for extra-nodal lymphoma (20%).
This quiz assesses understanding of the causes and effects of esophageal wall inflammation and neoplastic processes, including diagnosis and potential risks.
