Summary
Bile duct strictures, often caused by cancer, can also result from rare traumatic bile duct neuromas. This case highlights the importance of considering non-cancerous causes and utilizing advanced imaging and tumor markers for diagnosis and treatment.
Area of Science:
- Gastroenterology
- Surgical Oncology
- Diagnostic Imaging
Background:
- Proximal bile duct strictures commonly indicate cholangiocarcinoma.
- Post-cholecystectomy complications require thorough investigation.
- Elevated cancer antigen 19-9 (CA 19-9) levels often suggest malignancy.
Observation:
- A patient presented with jaundice and elevated CA 19-9 levels post-cholecystectomy.
- Endoscopic biliary stenting provided inadequate relief.
- Magnetic resonance imaging (MRI) aided in noninvasive diagnosis.
Findings:
- The bile duct stricture was pathologically identified as a traumatic bile duct neuroma, a rare benign tumor.
- Surgical resection and Roux-en-Y hepaticojejunostomy were successfully performed.
- The elevated CA 19-9 level, initially suggestive of malignancy, normalized post-operatively.
Implications:
- This case underscores the necessity of considering benign etiologies for bile duct strictures, even with elevated CA 19-9.
- Accurate interpretation of CA 19-9 levels and advanced imaging like MRI are crucial for differentiating benign from malignant conditions.
- Surgical intervention, including resection and biliary reconstruction, can be curative for traumatic bile duct neuromas.
