Precise clinical knowledge of liver anatomy is required to safely perform a hepatectomy, for both open and laparoscopic surgery. At the 19th meeting of the Japanese Research Society of Clinical Anatomy (JRSCA), we conducted special symposia on essential issues of liver surgery, such as the history of hepatic segmentation, the glissonean pedicle approach, application of 3-D imaging simulation and fluorescent imaging using indocyanine green solution, a variety of segmentectomies including caudate lobectomy, the associating liver partition and portal vein embolization for stage hepatectomy and harvesting liver grafts for living donor liver transplantation. The present review article provides useful information for liver surgeons and anatomic researchers.

“…Intraoperative ultrasonography was an essential procedure for the identification of hepatic tumors and intrahepatic vessels. A dye-staining technique (injection of indigo carmine and/or indocyanine green into the portal veins) [11-13] was used to delineate segmental boundaries on the liver surface, if needed. The hepatic parenchyma was divided using a clamp-crushing technique under intermittent hepatic inflow occlusion.…”

Surgical Approach to “Right Hepatic Core”: Deepest Region Surrounded by Major Portal Pedicles and Right Hepatic Vein

Background/Aims: The resection of hepatic tumors located in the region surrounded by the right hepatic vein (RHV) and the portal pedicles of the right paramedian/lateral sector (the right hepatic core) remains a challenge for liver surgeons. The aim of this study was to demonstrate the surgical techniques and outcomes of our atypical-parenchyma-sparing hepatectomy (atypical-PSH) approach for the removal of tumors in the right hepatic core. Methods: Perioperative records of 1,179 consecutive patients who had undergone hepatectomy for hepatocellular carcinoma or colorectal liver metastases from January 2006 to December 2014 were retrospectively reviewed. Results: Twenty-six patients (2%) had a tumor in the right hepatic core. Among them, 20 patients underwent atypical-PSH, including the anterior approach (resection of the right paramedian hepatic parenchyma, n = 9), posterior approach (resection of the right lateral hepatic parenchyma, n = 10), and transhepatic approach (tumor enucleation from the raw surfaces along the RHV, n = 1). Their postoperative outcomes were similar to the remaining 6 patients who had undergone right hepatectomy. Conclusions: Atypical-PSH can be safely applied for the removal of tumors in the right hepatic core. This technique may have potential advantages in preserving hepatic function for postoperative chemotherapy and repeated hepatectomy for future recurrence.

“…Between April 2000 and January 2013, 645 patients underwent liver resection for HCC at our institution. Among 509 patients undergoing initial liver resection, 255 had a single HCC 5 cm or less in diameter, and 131 of them had liver damage A [11,13] . After excluding 26 patients who underwent segmentectomy or hemihepatectomy, the final remaining total of 105 patients who underwent subsegmentectomy were evaluated ( Fig.…”

“…In those reports, however, the AR was segmentectomy and/or hemihepatectomy, and few previous studies have compared LR with AR (subsegmentectomy) in patients with different types of liver damage [10,11] . The purpose of the present historical cohort study was to determine the outcome of AR or LR in patients with NLF and a single lesion HCC, as well as to identify predictors of HCC recurrence.…”

Background: Hepatic resection for hepatocellular carcinoma (HCC) is now established as the treatment most likely to yield the best outcome. We aimed to clarify the risk factors for HCC recurrence after curative resection of single HCC in patients with normal liver function (NLF). Methods: The clinical records of 105 patients with NFL and a single HCC less than 5 cm in diameter who had undergone curative liver resection between April 2000 and January 2013 were investigated. We analyzed risk factors for recurrence of HCC. Results: Forty of the 105 patients suffered recurrence of HCC, and median recurrence-free survival (RFS) was 22.0 (5.1-148.5) months after surgery, and the liver was the most frequent site of recurrence. Univariate analysis showed that limited resection (LR; p = 0.002), the indocyanine green retention rate at 15 min (p = 0.023), C-reactive protein value (p = 0.001), bilirubin value (p = 0.042), neutrophil to lymphocyte ratio (p = 0.042), operation time (p = 0.018), and amount of bleeding (p = 0.011) were associated with RFS. Multivariate analysis showed that LR (p = 0.007) was a significant risk factor associated with RFS. Conclusion: LR is a risk factor for HCC recurrence in patients with single-lesion HCC and NLF.
