Minimally Invasive Approaches for Surgical Management of Primary Liver Cancers

摘要

The benefits of minimally invasive approaches in oncologic surgery are increasingly recognized, and laparoscopic liver surgery has become increasingly widespread. In light of the complexity and technical challenges of hepatobiliary procedures, robotic approaches are also employed. The utility, safety, and oncologic integrity of these methods in the management of primary liver cancers are reported. PubMed was used to search the medical literature for studies and articles pertaining to laparoscopic and robotic liver surgery. Studies that particularly addressed hepatocellular carcinoma and cholangiocarcinoma were identified and reviewed. Laparoscopic liver surgery, including for major resections, has been shown to be safe in experienced hands without any compromise of oncologic outcomes for either hepatocellular carcinoma or intrahepatic cholangiocarcinoma. Some studies show improved clinical outcomes including shorter hospital stays and lower complication rates when compared to open surgery, particularly for patients with cirrhosis. Robotic liver surgeries seem to have equally acceptable clinical outcomes; however, there is limited data regarding oncologic integrity and considerable additional expense. Laparoscopic and robotic liver resections are both feasible and safe for the management of primary liver tumors. Future studies should aim to clarify specific indications and optimize applications of these approaches.
