Since the introduction of Da Vinci robotic surgery, more and more complicated surgeries can now be performed robotically, yet there have been very few on robotic hepatectomy, especially when billiary reconstruction is involved. The video shows our initial experience with an anatomic hepatectomy using Da Vinci surgical robot. In this case, we also conducted billiary reconstruction due to the anatomic abnormality of bile duct, while applying the choledochoscopy. The preoperative diagnosis is primary liver carcinoma, tumor thrombi in bile duct, and hepatitis B. First, the gallbladder was resected, and cystic artery and duct were identified. After opening of the common bile duct above the junction, the choledochoscopy was performed. Tumor thrombi were found in common bile duct and left hepatic duct, and they were all removed. Left branches hepatic artery and portal vein were dissected, ligated, and divided. Thrombi in the left hepatic duct were removed also. After marking the cutting line along the ischemic boarder, liver parenchyma was transected using robotic harmonic scalpel. Branches of ducts were encountered and managed by either direct coagulating or dividing after clipping. The left hepatic vein was visualized, exposed, and divided during hepatectomy. Two T tubes were placed into common hepatic duct and the proximal cutting end of right anterior bile duct which was found to join the left hepatic duct, respectively. The operation went on successfully. The operation time was 410 minutes, the blood loss was 200 mL. The pathologic diagnosis was introductal papillary adenocarcinoma of left hepatic duct. The patient went on well postoperatively and was followed up for 22 months till now. Postoperative computed tomography examination showed no recurrence. Da Vinci-assisted robotic hepatectomy can be performed safely in the hands of experienced hepatobilliary surgeons, and choledochoscopy can be combined for bile duct exploration. With the advantages of Da Vinci robot system, complicated billiary reconstruction can be performed (http://links.lww.com/SLE/A74). Source

Purpose: Numerous studies have evaluated the association between XRCC1 Arg399Gln gene polymorphism and hepatocellular carcinoma risk in the Chinese Han population. However, the results have been inconsistent. We therefore here examined whether the XRCC1 Arg399Gln gene polymorphism confers hepatocellular carcinoma risk by conducting a meta-analysis. Methods: PubMed, Google scholar and China National Knowledge Infrastructure databases were searched for eligible articles in English and Chinese that were published before April 2012. Results: 6 studies involving 1,246 patients with hepatocellular carcinoma and 1,953 controls were included. The association between XRCC1 Arg399Gln gene polymorphism and hepatocellular carcinoma in the Chinese Han population was significant under GG vs AA (OR = 1.48, 95% CI = 1.13 to 1.94). Limiting the analysis to the studies with controls in the Hardy-Weinberg equilibrium, the results were persistent and robust. Conclusions: In the Chinese Han population, the XRCC1 Arg399Gln gene polymorphism is associated with an increased hepatocellular carcinoma risk. Source
