Clinical Report: Uncommon Case of Gastric Cancer with Ectopic Bile Duct

Background

Double common bile duct (DCBD) is a rare congenital anomaly, with ectopic drainage into the stomach being particularly uncommon. This condition has been linked to serious complications, including gastric cancer.

Data Highlights

No numerical or trial data were provided in the source material.

Key Findings

  • A 48-year-old male presented with gastric cancer linked to an accessory common bile duct draining into the stomach.
  • The patient underwent subtotal gastrectomy with Roux-en-Y gastrojejunostomy and D2 lymphadenectomy.
  • Intraoperative misidentification of the ACBD led to bile leakage.
  • Postoperative pathology confirmed signet ring cell carcinoma with neural invasion.

Clinical Implications

Accurate preoperative identification of biliary anatomy is essential to avoid complications during surgery.

Conclusion

This case highlights the importance of accurate ACBD diagnosis and proper surgical management.
