    Double common bile duct (DCBD) is a rare congenital anomaly, with accessory common bile duct (ACBD) drainage into the stomach being extremely uncommon.

  • 2

    A 48-year-old male was diagnosed with gastric cancer linked to ectopic ACBD drainage into the stomach after experiencing retrosternal pain and melena.

  • 3

    Intraoperatively, the ACBD was misidentified as an accessory left hepatic artery, leading to bile leakage after transection.

  • 4

    The patient underwent subtotal gastrectomy with various anastomoses, and postoperative pathology confirmed signet ring cell carcinoma.

  • 5

    Post-surgery, the reconstructed ACBD showed unobstructed drainage, highlighting the importance of accurate intraoperative identification.
