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 bisegmen- tectomy was mandatory. It represents the first description of a sinistroposition of both gallbladder and common bile duct. RESULTS: Surgical exploration revealed a left-side gall- bladder , located under the left lobe of the liver. During he- patic parenchyma dissection at the left side of the round liga- ment and the Rex recessus, the common bile duct was in- jured. Complete separation of hepatic pedicle structures showed that the upper biliary convergence passed on the left side of the Rex recessus before reaching the hepatoduo- denal ligament. CONCLUSION: Only careful dissection of the hepatoduo- denal ligament up to Rex recessus level prior to liver paren- chyma resection could avoid biliary tract injury during left lobectomy.
