Advances in minimally invasive liver surgery.

As in many surgical branches, minimally invasive methods are becoming increasingly prominent in hepatobiliary surgery. Nowadays, robotic and laparoscopic methods are among the hot topics in the current literature. Both laparoscopic and robotic surgery have better short-term results than open surgery in terms of the blood loss, need for blood transfusion, length of intensive care unit and hospital stay, and postoperative major complication rate. In addition to cosmetic benefits, minimally invasive methods have similar results to open surgery in terms of oncologic outcomes. Minimally invasive techniques for hepatocellular carcinoma, colorectal cancer liver metastasis and cholangiocarcinoma, which are the most common indications for surgery, also for donor and recipient surgeries in organ transplantation, can be safely applied in high-volume centers and by experienced surgeons. The use of robotic surgery is increasing especially in major hepatectomy operations. The main advantages of robotic surgery over laparoscopic surgery are less bleeding, less conversion rate and a shorter learning curve. However, there is a need for studies investigating the cost-effectiveness of robotic surgery, the production of devices such as robotic ultrasonographic dissectors, and the establishment of structured minimally invasive hepatobiliary surgery training programs. The aim of this review is to evaluate the recent findings and current evidence on minimally invasive hepatobiliary surgery.
