Study Notes
Achalasia of the Esophagus and Related Conditions
- Achalasia of the esophagus is characterized by absence of peristalsis and LES spasm, resulting in failure of esophageal emptying.
- Radiographic signs of achalasia include uniform esophageal dilatation, tapered "beak" deformity at the LES, esophagitis findings, increased incidence of epiphrenic diverticula, and esophageal carcinoma.
- Esophageal perforation is often caused by esophageal instrumentation during procedures such as endoscopy, dilation of esophageal stricture, foreign body removal, or esophageal endoprosthesis application.
- Esophagitis, commonly caused by gastroesophageal reflux disease (GERD), is a prevalent condition with various causes.
- Upper endoscopy, also known as esophagus-gastric-duodenoscopy (EGD), allows visualization of the esophageal lining using a flexible endoscope while the patient is sedated.
- Typical endoscopic findings of esophagitis include circular rings, linear furrows, whitish papules, and strictures.
- Biopsy involves the removal of a small esophageal tissue sample for microscopic examination.
- Barium X-ray imaging captures esophageal conditions after the patient ingests a barium solution, revealing ulceration, erosions, longitudinal fold thickening, and peptic stricture formation in moderate to severe reflux esophagitis.
