Minimally-invasive anatomical liver resection for hepatocellular carcinoma: a literature overview with technical and anatomical tips and tricks

Since its introduction in 1985, anatomical liver resection (AR) has been performed to treat early-stage hepatocellular carcinoma. The minimally-invasive AR (MIALR) approach can be safely performed at high-volume tertiary referral centers. The resection techniques can vary among surgeons, depending on the center’s experience, patient characteristics, hepatic segment involvement, and tumor characteristics. Profound knowledge of the liver’s surgical anatomy and a standardized inflow control approach is fundamental to performing MIALR safely. This article aims to summarize the applications of the MIALR and its outcomes, focusing on the techniques for vascular inflow control and the essential tips and tricks to standardize these techniques for laparoscopic and robotic approaches.
