Use of Imaging to Prevent Unnecessary Workup and Answer a Clinical Question

Area of Science:

• Gastroenterology and Hepatology
• Medical Imaging
• Vascular Surgery

Background:

• A significant portion of medical care, including diagnostic tests and treatments, may be unnecessary.
• Clinicians must critically evaluate the rationale for every medical order to ensure appropriateness.

Observation:

• A 71-year-old male with a history of Roux-en-Y gastric bypass presented with choledocholithiasis.
• An incidental finding revealed a persistently narrowed segment of the right bile duct.
• The narrowing was initially concerning for malignancy.

Findings:

• Multiple imaging modalities, including CT angiography and intravascular ultrasound, were employed.
• Endobiliary imaging during biliary drain management was crucial.
• The narrowing was definitively diagnosed as benign vascular compression by the right hepatic artery.

Implications:

• Minimally invasive imaging techniques can accurately diagnose benign conditions.
• Appropriate use of advanced imaging can prevent unnecessary diagnostic tests and reduce healthcare costs.
• This case underscores the importance of judicious test ordering in clinical practice.
