Question 1

Q: All of the following are true regarding Zenker's diverticulum EXCEPT?

It occurs in children. **Explanation:** Zenker’s diverticulum is a **pulsion diverticulum** caused by the herniation of the pharyngeal mucosa through a site of weakness in the muscular wall. 1. **Why Option B is the correct answer (False statement):** Zenker’s diverticulum is a disease of the **elderly**, typically occurring in the 7th or 8th decade of life. It is almost never seen in children because it is an acquired condition resulting from long-term incoordination of the cricopharyngeal muscle and increased intraluminal pressure. 2. **Why Option A is wrong (True statement):** It is a **false diverticulum** because it consists only of the mucosa and submucosa. A "true" diverticulum would involve all layers of the visceral wall, including the muscularis. 3. **Why Option C is wrong (True statement):** It is a **pulsion diverticulum** (pushed out by pressure) and it occurs **posteriorly** in the midline of the pharynx. 4. **Why Option D is wrong (True statement):** The anatomical site of herniation is **Killian’s dehiscence**, a triangular area of weakness between the thyropharyngeus and cricopharyngeus parts of the inferior constrictor muscle. **High-Yield Clinical Pearls for NEET-PG:** * **Clinical Presentation:** Regurgitation of undigested food, halitosis (foul breath due to stagnant food), dysphagia, and a gurgling sound in the neck (Boyce’s sign). * **Diagnosis:** The investigation of choice is a **Barium Swallow**, which shows a pouch behind the esophagus. * **Management:** Endoscopic Dohlman’s procedure (stapling the party wall) or open diverticulectomy with cricopharyngeal myotomy. * **Complication:** Aspiration pneumonia is the most common serious complication.
