Question 1

Q: All of the following are true about congenital hypertrophic pyloric stenosis except

Metabolic acidosis occurs. ***Metabolic acidosis occurs*** - Due to persistent **vomiting** from pyloric stenosis, there is a significant loss of **hydrochloric acid (HCl)** from the stomach. - This loss of gastric acid leads to **hypochloremic metabolic alkalosis** rather than acidosis. *More common in males* - **Pyloric stenosis** has a clear male predominance, with a male-to-female ratio of about 4:1. - This gender disparity is a well-established epidemiological feature of the condition. *RamStedt Pyloromyotomy is the treatment of choice* - The **Ramstedt pyloromyotomy** is the definitive surgical procedure for congenital hypertrophic pyloric stenosis. - This procedure involves incising the hypertrophied muscle of the pylorus while leaving the mucosa intact, thus relieving the obstruction. *Non Bilious vomiting is seen* - The vomiting in pyloric stenosis is typically **non-bilious** because the obstruction is proximal to the **ampulla of Vater**, where bile enters the duodenum. - Vomiting usually occurs forcefully (projectile) after feeding.
