Surgical intervention in a patient with a double gallbladder with a septum and multiple cystic ducts. A: during cholecystectomy, the presence of two gallbladders along with their corresponding cystic ducts was detected. Successful extraction of the biliary stones was performed, followed by cholecystectomy of both gallbladders. Rectangle delineates double cystic ducts directing towards the gallbladders; B: in close proximity to the normal gallbladder, a second accessory gallbladder was observed. The smaller cystic duct was separated and inserted into the bile duct approximately 0.5 cm proximal to the other cystic duct. The surgical team was able to clearly identify both cystic ducts during the procedure. White arrows indicate cystic duct apertures of the normal and accessory gallbladders.

Anatomical variations observed during cholecystectomy in a patient with a double gallbladder. a: the separation between the two distinct gallbladders is depicted by the white dashed lines. The presence of two different cystic ducts is indicated by the white arrows; b: the gallbladder is characterized by the presence of a septum, and there are two cystic ducts; c: successful extraction of the biliary stones was performed, followed by cholecystectomy of both gallbladders. The septum is highlighted by white arrows; d: the classification of multiple gallbladders, as proposed by Harlaftis et al.[6] Type B2* was specifically described in the present case.
