“…Based on these reports, Cho et al 12 reported the AFV (V8) as a landmark vein between the ventral and dorsal segments of the anterior section; however, it had variations in the number of veins (a mean of 1.2 branches per patient) and in connecting hepatic vein (RHV or MHV) 11 . Several studies have verified the AFV in patients with normal livers 18‐20 . Kaneko et al 18 reported that the AFV could be identified from S8 to S5 in only 1% of the cases and even after the identification of the AFV, the boundary between the ventral and dorsal parts of the anterior section could not be determined by the AFV.…”

Taniai et al 19 also reported that the AFV could be identified only in S8 and might not be easily identifiable due to the various branching types. Furthermore, Kobayashi et al 20 revealed that the AFV can be used as a landmark in S8 appearing in only about 60% of cases.…”

Right-sided ligamentum teres (RSLT) is a rare congenital anomaly in which the fetal umbilical vein is connected to the right paramedian trunk. It was first described as left-sided gallbladder (LSGB) by Hochstetter et al. 1 This anomaly was initially thought to involve displacement of the gallbladder to the left side of the ligamentum teres (LT), but in 1997, Nagai et al 2 reported that LSGB resulted from anomalous attachment of the LT to the right paramedian trunk. Confusion regarding this anatomy persists due to the thought that the gallbladder position changed in patients with RSLT. A previous report proposed that LSGB occurred owing to ectopic gallbladder attachment to the left lobe of the liver, 3 whereas others suggested that sinistroposition of the gallbladder occurred due to developmental failure of the quadrate lobe. 4 The origin of this anomaly has not been fully explained but confusion has increased with a report of rightsided gallbladder in patients with RSLT. 5 Although we are likely to encounter patients with RSLT because it has an estimated prevalence of around 1%,

“…Major hepatic veins, which run in the boundaries between the anatomical sections or segments, 26 are known as critical internal landmarks during the liver transection. [27][28][29] Especially, the root-sided major hepatic veins indicate the boundaries. An HVGA procedure in which the major hepatic vein is exposed continuously from its root side enables to dissect almost all boundaries without identifying the anatomic area using the Glissonean approach during the liver resection of the cranial region, such as segment VII or VIII.…”

Background The concept of minimally invasive anatomic liver resection (MIALR) is gaining popularity. However, specific technical skills need to be acquired to safely perform MIALR. The “Expert Consensus Meeting: Precision Anatomy for Minimally Invasive HBP Surgery (PAM‐HBP Surgery Consensus)” was developed as a special program during the 32nd meeting of the Japanese Society of Hepato‐Biliary‐Pancreatic Surgery (JSHBPS). Methods Thirty‐four international experts gathered online for the consensus. A Research Committee performed a comprehensive literature review, classifying studies according to the Scottish Intercollegiate Guidelines Network method. Based on the literature review and experts’ opinions, tentative recommendations were drafted and circulated among experts using online Delphi Rounds. Finally, formulated recommendations were presented online in the Expert Consensus Meeting of the JSHBPS on February 23rd, 2021. The final recommendations were validated and finalized by the 2nd Delphi Round in May 2021. Results Seven clinical questions were selected, and 22 recommendations were formulated. All recommendations reached more than 85% consensus among experts at the final Delphi Round. Conclusions The Expert Consensus Meeting for safely performing MIALR has presented a set of clinical guidelines based on available literature and experts’ opinions. We expect these guidelines to have a favorable effect on the safe implementation and development of MIALR.

“…Preoperative examination of liver function is important in hepatic surgery, especially for elderly patients with HCC 30 32 . Use of three-dimensional reconstruction for preoperative simulation of intrahepatic vessels is necessary for safe LH 33,34 . Laparoscopic ultrasound should be performed before liver transection and reveals tumor location, vascular anatomy, and the adequate incision line.…”

Before the first laparoscopic hepatectomy (LH) was described in 1991, open hepatectomy (OH) was the only choice for surgical treatment of liver tumors. LH indications were initially based solely on tumor location, size, and type. Use of LH has spread rapidly worldwide because it reduces incision size. This review systematically assesses the current status of LH. As compared with OH, LH is significantly less complicated, requires shorter hospital stays, and results in less blood loss. The long-term survival rates of LH and OH are comparable. Development of new techniques and instruments will improve the conversion rate and reduce complications. Furthermore, development of surgical navigation will improve LH safety and efficacy. Laparoscopic major hepatectomy for HCC remains a challenging procedure and should only be performed by experienced surgeons. In the near future, a training system for young surgeons will become mandatory for standardization of LH, and LH will likely become better standardized and have broader applications.
