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

Which percentage of gastric ulcers are located at the gastroesophageal junction (GEJ)?

1. 10%

2. 15%

3. 5%

4. 20%

The correct answer is: 5%

The correct answer indicates that approximately 5% of gastric ulcers are located at the gastroesophageal junction (GEJ). This is an important statistic that highlights the relatively low incidence of gastric ulcers at this specific anatomical site compared to other locations within the stomach. Understanding the frequency of gastric ulcers in relation to their anatomical placement is crucial for surgical specialists because it allows for targeted diagnosis and treatment strategies. The majority of gastric ulcers typically occur in the antrum or body of the stomach rather than at the GEJ. This is due to the differences in mucosal exposure to irritants and the distinct blood supply in these areas. Recognizing that the GEJ is a less common site for gastric ulcers helps healthcare providers to consider alternative diagnoses in cases of symptoms suggesting ulceration, such as epigastric pain or bloating. It also informs decisions regarding surveillance and management, especially in patients presenting with reflux or dysphagia, as the involvement of this junction may require a different therapeutic approach compared to ulcers located elsewhere in the gastric tissue.
