| 8 | Scoring criteria for determining the safety of liver resection for malignant liver tumors显示文摘BACKGROUND Liver resection has become safer as it has become less invasive.However,the minimum residual liver volume(RLV)required to maintain homeostasis is unclear.Furthermore,the formulae used to calculate standard liver volume(SLV)are complex.AIM To review previously reported SLV formulae and the methods used to evaluate the minimum RLV,and explore the association between liver volume and mortality.METHODS A systematic review of Medline,PubMed,and grey literature was performed.References in the retrieved articles were cross-checked manually to obtain further studies.The last search was conducted on January 20,2019.We developed an SLV formula using data for 86 consecutive patients who underwent hepatectomy at our institution between July 2009 and August 2011.RESULTS Linear regression analysis revealed the following formula:SLV(mL)=822.7×body surface area(BSA)?183.2(R2=0.419 and R=0.644,P<0.001).We retrieved 25 studies relating to SLV formulae and 12 studies about the RLV required for safe liver resection.Although the previously reported formulae included various coefficient and constant values,a simplified version of the SLV,the common SLV(cSLV),can be calculated as follows:cSLV(mL)=710 or 770×BSA.The minimum RLV for normal and damaged livers ranged from 20%-40%and 30%-50%,respectively.The Sapporo score indicated that the minimum RLV ranges from 35%-95%depending on liver function.CONCLUSION We reviewed SLV formulae and the minimum RLV required for safe liver resection.The Sapporo score is the only liver function-based method for determining the minimum RLV. | Kohei Harada Minoru Nagayama Yoshiya Ohashi Ayaka Chiba Kanako Numasawa Makoto Meguro Yasutoshi Kimura Hiroshi Yamaguchi Masahiro Kobayashi Koji Miyanishi Junji Kato Toru Mizuguchi | 2019 | World Journal of Meta-Analysis2019，7，5： | 0 |
