Anatomical resection(AR)has been reported to achieve better long-term outcomes than non-anatomical resection for the treatment of hepatocellular carcinoma(HCC).The surgical feasibility and oncological significance of laparoscopic AR(LAR),especially“subsegment resection”,“cone unit resection”,and repeat LAR for HCC,remain *** present a 67-year-old patient with alcoholic liver cirrhosis and HCC who underwent full LAR three times,focusing on the technical aspects of the Glissonean *** LAR for recurrent HCC could be a safe and feasible ***,HCC recurred in the neighboring segment twice,even though pathological vascular invasion and marginal remnants were not *** should investigate the oncological significance and advancements in subsegmentectomy and cone unit resection,in the future.

BACKGROUND Laparoscopic anatomical liver resection has become more challenging because some subsegmental Glissonean pedicles are hard to ***,we introduce how to dissect every(sub)segmental Glissonean pedicle from the first porta hepatis and perform standardized(sub)segmentectomy[from segment 1(S1)to S8].AIM To summarize our methods of laparoscopic anatomical segmental and subseg-mental liver *** The Glisson sheath and liver capsule were separated along the Laennec *** Glissonean pedicle could be isolated and transected with little or no parenchymal damage through this extra-Glissonean dissection *** basin of the(sub)segment was determined by the ischemia demarcation line or indocyanine green *** hepatic vein or intersegmental vein was also used to guide the plane of parenchymal *** All segmental or subsegmental pedicles or even the pedicle of the cone unit could be dissected along the Laennec membrane using our novel technique through the first porta *** dorsal branches of S8,the branches of S4a and the paracaval portion branches(b/c vein)of the caudate lobe were the most difficult to *** The novel techniques of liver segmental and subsegmental pedicle anatomy is feasible for laparoscopic liver resection and can help accurately guide(sub)segmentectomy from S1 to S8.
