Laparoscopic liver resection for hepatocellular carcinoma

Abstract

Hepatocellular carcinoma (HCC) represents the most common indication of laparoscopic liver resection (LLR). It must be acknowledged that most series concern minor hepatectomies for peripheral lesions located in favorable segments, and such procedures are now performed in the majority of HPB centers. However, there are growing reports concerning major hepatectomies (i.e., 3 segments or more) and complex resections such as anatomical resections in difficult segments (i.e., postero-superior). Retrospective comparative studies, including some with propensity score matching, and meta-analyses showed that LLR is associated with short-term benefits including reduced blood loss, length of stay and morbidity with identical oncological results and survival rates. In addition, laparoscopy leads to less post-operative abdominal adhesions, improving operative outcomes in case of repeat hepatectomy or secondary liver transplantation. Despite the lack of results of randomized-controlled trials in HCC, a consensus exists that the laparoscopic approach can improve the outcome of major liver resections, provided it is performed in experienced centers. This requires specific high-quality training.
