[Evidence of minimally invasive oncological surgery of the liver].

BACKGROUND

The evidence for minimally invasive surgery (MIS) of the liver has significantly increased with the increasing number of publications on this topic in recent years; however, this technique has not yet gained broad acceptance among surgeons.

OBJECTIVE

Analysis and presentation of the current literature on MIS of the liver.

MATERIAL UND METHODS

Structured PubMed literature search and analysis.

RESULTS

According to the literature, MIS and open liver surgery are equivalent regarding the oncological quality. In addition to parenchyma-preserving resections, major hepatectomies (e.g. hemihepatectomy and sectorectomy), two-stage concepts and re-resections have increasingly been reported. The MIS of the liver is associated with less blood loss and other immunological advantages in addition to a shorter hospital stay. The highest level of evidence has been achieved for colorectal liver metastases for which a systematic review even revealed a survival benefit for patients undergoing MIS surgery. From an oncological perspective, laparoscopic and robotic liver surgery are considered to be equivalent.

CONCLUSION

According to the current literature MIS of the liver is recommended for the resection of colorectal liver metastases and hepatocellular carcinoma.
