Imaging of the stomach and duodenum

Area of Science:

• Gastroenterology
• Diagnostic Imaging
• Surgical Oncology

Background:

• Challenges exist in differentiating gastritis from gastric cancer using computed tomography (CT).
• Evaluating gastric cancer with endoscopic ultrasonography (EUS) poses difficulties.
• Gastric cancer associated with Crohn's disease is noted as a potential complication.

Purpose of the Study:

• To highlight diagnostic challenges in gastrointestinal imaging.
• To review current applications and limitations of CT and EUS in gastric pathology.
• To discuss interventional radiology techniques for nutritional support.

Main Methods:

• Review of CT findings in gastritis and peptic ulcer disease.
• Evaluation of endoscopic ultrasonography in gastric cancer assessment.
• Discussion of barium upper gastrointestinal studies versus endoscopy.
• Analysis of fluoroscopic placement of nasoenteric tubes.

Main Results:

• Difficulties in distinguishing gastritis from gastric cancer on CT are confirmed.
• The reliability of radiologic diagnosis for duodenitis is questioned.
• Four cases illustrate gastric cancer as a complication in Crohn's disease.
• Patient preference and diagnostic accuracy of barium studies versus endoscopy are debated.

Conclusions:

• Accurate distinction between gastritis and gastric cancer on CT requires careful evaluation.
• Endoscopic ultrasonography requires further refinement for precise gastric cancer staging.
• Gastric cancer is a potential, albeit rare, complication in Crohn's disease.
• Interventional radiology techniques, such as fluoroscopic tube placement, offer valuable feeding options.
