Surgical Management of Extrahepatic Biliary Neuroendocrine Tumors A Rare Case Report

Introduction Extrahepatic biliary neuroendocrine tumors (EBNETs) are exceptionally rare neoplasms, with limited documented cases worldwide. These tumors often present diagnostic challenges due to their resemblance to more common biliary malignancies like cholangiocarcinoma. This article delves into a recently published case that highlights the surgical approach and clinical considerations for EBNETs.

Case Overview: Diagnosis and Presentation A 41-year-old woman presented with non-specific abdominal pain and significantly elevated liver function tests (LFTs). Imaging studies revealed a mass in segment 4 of the liver, initially suspected to be a benign hepatic adenoma. However, further diagnostic evaluations, including a percutaneous biopsy, confirmed a neuroendocrine tumor.

Surgical Intervention and Management

• The tumor was located in the anterior aspect of the liver hilum, involving the proximal common hepatic duct (CHD).
• A total resection of the common bile duct (CBD) and CHD was performed.
• A complex lymphadenectomy around the celiac artery was conducted to ensure complete tumor excision.
• Postoperative pathology confirmed a well-differentiated neuroendocrine tumor (NET) with a low proliferation index (Ki-67 <2%).

Insights from Medical Experts The American College of Surgeons (ACS) highlights that surgical resection remains the gold standard for managing localized EBNETs. However, due to the tumor’s rare nature, preoperative diagnosis is challenging, often requiring histopathological confirmation post-surgery.

Broader Implications in Neuroendocrine Tumor Management

• Challenges in Diagnosis: Many EBNETs are diagnosed intraoperatively due to their non-specific imaging characteristics.
• Surgical Considerations: Resection with free margins is critical for long-term prognosis.
• Alternative Treatments: Patients with inoperable tumors may benefit from systemic therapies like somatostatin analogs or peptide receptor radionuclide therapy (PRRT).
