 A 58-year-old male was referred to our hospital for liver dysfunction and choledocholithiasis. Abdominal ultrasound and computed tomography (CT) showed two gallbladders in the gallbladder bed as well as stones in the main gallbladder. Magnetic resonance cholangiopancreatography (MRCP) revealed that each cystic duct communicated separately with the common bile duct (CBD) and there were stones in the CBD. The patient was diagnosed with a double gallbladder, classified as Gross type B, with CBD stones. After the CBD stones were removed via endoscopic retrograde cholangiopancreatography (ERCP), laparoscopic cholecystectomy was performed. Four trocars were used at the usual placements. Both gallbladders were covered with the same serosa, and the two cystic ducts were adhered to each other. The cystic ducts were dissected, separately clipped, and divided. The gallbladders were then removed. The patient was discharged on postoperative day 4 with no postoperative complications. The double gallbladder is a rare congenital anomaly. When using laparoscopic cholecystectomy for patients with a double gallbladder, the surgeon should carefully identify the anatomy of the gallbladder and bile duct in order to avoid surgical complications.
