65 year old patient comes with dysphagia and regurgitation. Barium swallow shows diverticula at lower oesophagus. Which of the following is false about this condition
**Core Concept**
The patient's symptoms of dysphagia and regurgitation, along with the presence of diverticula on a barium swallow, suggest a diagnosis of esophageal diverticula. This condition involves the formation of pouches or sacs in the esophagus, which can lead to symptoms such as dysphagia, regurgitation, and sometimes chest pain.
**Why the Correct Answer is Right**
Esophageal diverticula are most commonly found in the lower esophagus, near the junction with the stomach. The formation of these diverticula is often due to increased pressure and stress on the esophageal wall, which can be caused by conditions such as gastroesophageal reflux disease (GERD). The diverticula can trap food and liquids, leading to symptoms such as dysphagia and regurgitation. The pathophysiology of esophageal diverticula involves the weakening of the esophageal wall, which can be due to various factors such as inflammation, scarring, or muscular dystrophy.
**Why Each Wrong Option is Incorrect**
**Option A:** Esophageal diverticula are most commonly found in the lower esophagus. This statement is true, as diverticula are most frequently located near the junction with the stomach.
**Option B:** Esophageal diverticula can lead to symptoms such as dysphagia and regurgitation. This statement is true, as the diverticula can trap food and liquids, causing these symptoms.
**Option C:** The formation of esophageal diverticula is often due to increased pressure and stress on the esophageal wall. This statement is true, as conditions such as GERD can increase pressure on the esophageal wall, leading to diverticula.
**Clinical Pearl / High-Yield Fact**
A key clinical feature of esophageal diverticula is the presence of dysphagia and regurgitation, which can be relieved by lying down or assuming a prone position. This is due to the fact that gravity can help to alleviate the symptoms by allowing food and liquids to flow more easily through the esophagus.
**Correct Answer:** D
