OPEN, LAPAROSCOPIC, AND ROBOTIC-ASSISTED HEPATECTOMY IN RESECTION OF LIVER TUMORS: A NON-SYSTEMATIC REVIEW.

introductionSeveral factors have made hepatectomy an increasingly safe surgery and new drugs allowed surgical treatment for patients who initially were not candidates for resection. Lesions often require resection, which can be performed by open, laparoscopic, or robotic assisted hepatectomy.

aimCompare the surgical techniques in open, laparoscopic, and robotic assisted hepatectomy for resection of liver tumors.

methodsLiterature review based on scientific papers published on Lilacs/Pubmed/Scielo in the last 17 years regarding the indications of these techniques for liver tumor resections and on papers comparing such techniques.

resultsThe comparative study shows the benefits of laparoscopic surgery over open surgery, such as smaller incisions, less postoperative pain, shorter recovery time, smaller immune and metabolic response, and quicker restoration of oral ingestion as well as lower morbidity rates. However, the need for a specialized surgical team and the reduction in handling area still remain as disadvantages in the laparoscopic technique. It is yet not clear whether robotic assistance presents considerable benefits over the laparoscopic technique considering that high acquisition and maintenance costs are limiting factors.

conclusionDespite all challenges, laparoscopic hepatectomy presents many benefits over open surgery. The robotic assisted technique is still in evolution as many centers in the world perform hepatic resections with the platforms but only after a thorough patient selection. Thus, laparoscopy stands as the best option, unless there is some contraindication to the procedure.
