Incidental Discovery of Situs Inversus of the Gallbladder Due to Stones During a Coelioscopic Approach

Atypical location of the gallbladder to the left of the round ligament is a rare anomaly of the biliary system. Although the term left-sided gallbladder (LSG) is commonly used, this definition can lead to confusion due to lack of anatomical precision. This report describes an atypical gallbladder location associated with right ligamentum teres (RSLT) and an abnormal intrahepatic portal venous branch, surgically removed by standard laparoscopy without radical change to the standard technical procedure after careful lesion assessment. This article testifies to the rarity of a left gallbladder localization due to atypical portal and ligament anatomy that may be associated, emphasizing the importance of recognizing these anomalies during a laparoscopic approach. It provides valuable recommendations for preventing complications, particularly in the context of hepatobiliary and transplantation procedures, underlining its clinical and technical relevance to the surgical community.
