Question

Which type of ulcer is more common in PUD, gastric or duodenal?

Gastric ulcers typically occur in which histological region of the stomach?

Gastric ulcers usually occur on which curvature of the stomach?

Which artery is at risk of rupturing in a gastric ulcer in this location?

Duodenal ulcers most commonly occur on which part of the duodenum?

Duodenal ulcers typically perforate on the anterior or posterior aspect of the duodenum?

Which artery is at risk of rupturing in a posterior duodenal ulcer?

What is the consequence of an anterior duodenal ulcer rupturing?

Answer 1

Gastric ulcers are more common in PUD than duodenal ulcers. They occur in the antrum region of the stomach and on the lesser curvature. Duodenal ulcers usually occur on the first part of the duodenum and perforate on the posterior aspect. Rupture of a gastric ulcer can lead to peritonitis.

Step-by-step explanation:

Gastric ulcers are more common in peptic ulcer disease (PUD) than duodenal ulcers. Gastric ulcers typically occur in the antrum region of the stomach. They usually occur on the lesser curvature of the stomach. In a gastric ulcer in this location, the left gastric artery is at risk of rupturing.

Duodenal ulcers most commonly occur on the first part of the duodenum. They typically perforate on the posterior aspect of the duodenum. In a posterior duodenal ulcer, the superior pancreaticoduodenal artery is at risk of rupturing.

If an anterior duodenal ulcer ruptures, it can cause peritonitis (inflammation of the lining of the abdominal cavity) and potentially lead to a life-threatening condition.
