Abstract

Purpose: The goal of this article was to characterize and explain the etiology of a left-sided gallbladders with intrahepatic portal vein anomalies, and these cases of this unusual anatomy were all encountered at a single center.
Methods: We reviewed the movies recorded during surgery, the database information and the preoperative radiologic examinations of 1,141 patients who underwent cholecystectomies at our institution between August 2007 and July 2010 to assess the presence of left-sided gallbladder and its combined anomalies.
Results: Four of 1141 patients (0.35%) were diagnosed with left-sided gallbladder. In all the cases, the gallbladder was located on the left side of the falciform ligament, under the left lobe of the liver with typical abnormal intrahepatic portal venous branching. The right posterior portal vein came directly from the main portal vein, and the right anterior portal vein originated from the left portal vein, but the ligamentum teres joined to the left branch of the portal vein in the liver.
Conclusion: Left-sided gallbladder with intrahepatic portal venous branching anomaly resulted from the defective development of the central portion of the liver rather than from abnormal regression of the left umbilical vein with persistence of the right umbilical vein.
