Sinistroposition of the gallbladder and common bile duct.
BACKGROUND
Despite its rare incidence, few cases of left-side gallbladder have been already published.


METHODS
We reported herein the case of a 29-year-old man with a left liver tumor in whom left lateral bisegmentectomy was mandatory. It represents the first description of a sinistroposition of both gallbladder and common bile duct.


RESULTS
Surgical exploration revealed a left-side gallbladder, located under the left lobe of the liver. During hepatic parenchyma dissection at the left side of the round ligament and the Rex recessus, the common bile duct was injured. Complete separation of hepatic pedicle structures showed that the upper biliary convergence passed on the left side of the Rex recessus before reaching the hepatoduodenal ligament.


CONCLUSIONS
Only careful dissection of the hepatoduodenal ligament up to Rex recessus level prior to liver parenchyma resection could avoid biliary tract injury during left lobectomy.
