Misdiagnosis of Intrahepatic Biliary Cystadenoma Located in the Caudate Lobe: A Case Report.

Background: Intrahepatic Biliary Cystadenoma (IBC) is rare but has a high incidence of misdiagnosis, especially for experienceless surgeons.

Case: We report a case of IBC located in the caudate lobe and described a typical procedure of misdiagnosing this disease. Finally, the patient was successfully cured, but the procedure of misdiagnosis should attract attention.

Catheterization of the gallbladder: A novel mouse model of severe acute cholangitis.

Aim: To establish a severe acute cholangitis (SAC) model in mice.

Methods: Cholecystic catheterization was performed under the condition of bile duct ligation (BDL). Trans-cholecystic injection of lipopolysaccharide (LPS) was defined as the SAC animal model.
