American Board of Surgery Qualifying Exam (ABS QE) Practice Test

Which type of gastric ulcer is primarily located in the antrum?

1. Type 1

2. Type 2

3. Type 3

4. Dodda ulcer

The correct answer is: Type 1

The correct answer, Type 1 gastric ulcer, is primarily located in the antrum of the stomach. This type of ulcer is often associated with chronic gastritis and has a strong correlation with factors such as the use of non-steroidal anti-inflammatory drugs (NSAIDs) and Helicobacter pylori infection. Type 1 gastric ulcers typically indicate a condition in which there is an imbalance between protective factors and aggressive factors in the gastric mucosa, leading to ulceration in the antrum. The antrum is the lower portion of the stomach, which plays a crucial role in the digestive process and is particularly vulnerable in the case of Type 1 ulcers due to its exposure to acid and pepsin. Type 2 and Type 3 ulcers usually occur in different areas of the stomach, specifically in the body of the stomach and the duodenum, respectively, and are thus not primarily antral in location. The Dodda ulcer is a less common term and is often used to refer to deeper ulcers connected to preceding surgeries or conditions that do not directly align with the typical classification of gastric ulcers. Understanding the anatomical locations and risk factors involved with these types provides insight into their clinical management and treatment strategies.
