Complete radio frequency ablation of hepatocellular carcinoma adjacent to the main bile duct and blood vessels between the first and the second hepatic portal.

In cases where hepatocellular carcinoma cannot be surgically removed either due to the capacity of hepatic functional reserve or the special location of the tumor, a radiofrequency ablation (RFA) is recognized to be an effective and minimally invasive treatment. However, when the tumor is adjacent to the main bile duct and blood vessels, it is feared that due to the "heat-sink effect" of the blood and the possible damage to the duct and blood vessels, complete tumor ablation is hard to achieve. We report here a case of complete RFA of hepatocellular carcinoma, adjacent to the main bile duct and blood vessels between the first and the second hepatic portal, with emphasis on the safety of the approach for complete ablation of the tumor.

Experience from surgical resection for 48 cases of hilar cholangiocarcinoma / 中华外科杂志

<p><b>OBJECTIVE</b>To summarize the methods, safety and efficiency of surgical resection for hilar cholangiocarcinoma.</p><p><b>METHODS</b>The clinical and follow-up data of 48 patients with hilar cholangiocarcinoma underwent surgical resection from January 2003 to December 2007 were analyzed retrospectively. There were 26 male and 22 female, aged from 38 to 72 years old with a mean of 63.6 years old.</p><p><b>RESULTS</b>Perioperative management including percutaneous transhepatic biliary drainage applied in 19 cases and portal vein embolization applied in 2 cases. Eight patients were treated with extrahepatic bile duct resection with or without parital hepatic segment II resection, 10 cases with perihilar hepatic resection (segment IVB, partial V, partial VIII, I), 28 cases with extended hemihepatectomy and 2 cases with central hepatic resection (segment IVB, V, VIII, I). R0 resection rate was 89.5% and the operative mortality was 2.1%. The 1-, 3- and 5-year survival rate were 93.5%, 51.8% and 36.5%, respectively. Patients undergoing extended hepatic resection survived significantly longer than those undergoing partial hepatic resection (P = 0.034).</p><p><b>CONCLUSIONS</b>Extended hepatic resection for hilar cholangiocarcinoma offers good outcomes with an acceptable mortality rate.</p>
