**Question:** Surgery of choice for chronic duodenal ulcer is:

A. Billroth I anastomosis
B. Billroth II anastomosis
C. Total gastrectomy
D. Pyloroplasty

**Correct Answer:** D. Pyloroplasty

**Core Concept:**
Chronic duodenal ulcers are typically caused by a long-standing infection with Helicobacter pylori (H. pylori) or the use of nonsteroidal anti-inflammatory drugs (NSAIDs). Treatment options for chronic duodenal ulcers include medical management with antibiotics, proton pump inhibitors (PPIs), and antacids, as well as surgical management. Surgical options aim to restore the integrity of the gastrointestinal tract and ensure adequate gastric emptying.

**Why the Correct Answer is Right:** Pyloroplasty is the correct surgical choice for chronic duodenal ulcers because it focuses on the underlying pathophysiology of the condition. In cases of chronic duodenal ulcers, the primary issue is impaired gastric emptying due to pyloric stenosis, which results from the ulcer itself or previous surgery. Pyloroplasty involves dividing and relaxing the pyloric sphincter to improve gastric emptying and promote healing of the ulcer.

**Why Each Wrong Option is Incorrect:**

A. Billroth I anastomosis: This procedure involves the connection of the stomach to the small intestine in two separate steps, which does not address the primary issue of impaired gastric emptying in chronic duodenal ulcers.

B. Billroth II anastomosis: Similar to Billroth I anastomosis, this procedure does not correct the pyloric stenosis and impaired gastric emptying, which is the primary issue in chronic duodenal ulcers.

C. Total gastrectomy: Total gastrectomy is a drastic procedure that involves the removal of the entire stomach. While it is a definitive treatment for severe cases of duodenal ulcers, it is not a suitable choice for chronic duodenal ulcers, where the primary issue is pyloric stenosis and impaired gastric emptying.

**Clinical Pearl:** Chronic duodenal ulcers, particularly those caused by H. pylori infection or NSAID use, often present with recurrent episodes of epigastric pain and malabsorption symptoms due to impaired gastric emptying. In cases where medical management has failed or is contraindicated, pyloroplasty (also known as pyloromyotomy) should be considered. This procedure aims to address the primary issue of pyloric stenosis and impaired gastric emptying, thus promoting ulcer healing and improving symptoms.

**Why Pyloroplasty is Right:** Pyloroplasty is the correct surgical choice for chronic duodenal ulcers because it directly addresses the underlying issue of pyloric stenosis and impaired gastric emptying, which is often the primary cause or contributing factor in chronic duodenal ulcers. By relieving the pyloric obstruction, pyloroplasty helps to improve gastric emptying and promotes ulcer
