**Core Concept**
The management of a perforated duodenal ulcer involves surgical intervention to prevent peritonitis and restore gastrointestinal continuity. The most common operative procedure is a definitive treatment that aims to close the perforation while minimizing morbidity and mortality.

**Why the Correct Answer is Right**
The most commonly practiced operative procedure for a perforated duodenal ulcer is a **gastric partitioning operation**, also known as **Omental Patch Repair** or **Gastric Patch Closure**. This procedure involves covering the perforation with a piece of omentum, which is a fatty tissue that lines the abdominal cavity. The omentum is then sutured in place to prevent further leakage of gastric contents into the peritoneal cavity. This approach is preferred because it is relatively simple, minimizes the risk of complications, and allows for rapid recovery.

**Why Each Wrong Option is Incorrect**
**Option A:** This option is incorrect because **Total Gastrectomy** is a more extensive surgical procedure that involves removing the entire stomach, which is not typically required for a perforated duodenal ulcer.
**Option B:** This option is incorrect because **Pyloroplasty** is a surgical procedure that involves widening the pyloric channel to improve gastric emptying, which is not relevant to the management of a perforated duodenal ulcer.
**Option C:** This option is incorrect because **Gastrojejunostomy** is a surgical procedure that involves creating a connection between the stomach and the jejunum, which is not the primary goal of managing a perforated duodenal ulcer.

**Clinical Pearl / High-Yield Fact**
It is essential to diagnose and manage a perforated duodenal ulcer promptly to prevent peritonitis and minimize morbidity and mortality. A high index of suspicion and prompt surgical intervention are critical in managing this condition.

**Correct Answer:** C. Gastrojejunostomy is incorrect. The correct answer is actually Omental Patch Repair or Gastric Patch Closure, but the option is not provided.
