Summary
Extrahepatic biliary neuroendocrine tumors (EBNETs) are rare and challenging to diagnose. This case demonstrates the feasibility of preoperative diagnosis via endoscopic biopsy, supporting surgical resection as the primary treatment for EBNETs.
Area of Science:
- Gastroenterology
- Surgical Oncology
- Pathology
Background:
- Extrahepatic biliary neuroendocrine tumors (EBNETs) are exceptionally rare.
- Diagnosis is typically confirmed postoperatively via histology.
- Current management relies on limited retrospective data.
Observation:
- A 77-year-old male with fatty liver disease incidentally found to have a biopsy-proven EBNET.
- No other suspicious lesions were detected on further investigation.
- The patient underwent tumor resection with Roux-en-Y hepaticojejunostomy.
Findings:
- Final pathology confirmed a grade 1, well-differentiated neuroendocrine tumor.
- This represents the third reported case with a preoperative EBNET diagnosis via endoscopic biopsy.
- Surgical resection is the established gold standard treatment.
Implications:
- Preoperative diagnosis of EBNETs is achievable through endoscopic biopsy.
- Early and accurate diagnosis facilitates timely surgical intervention.
- Complete surgical resection remains crucial for optimal patient outcomes.
