Comparative study of three-dimensional visualization technology and two-dimensional imaging technology in liver resection of liver cancer patients

Objective To compare the efficacy of three-dimensional visualization technology and two-dimensional imaging technology in liver resection of liver cancer(LC)patients.Methods 118 LC patients admitted in Shenyang Fourth People’s Hospital from October 2014 to October 2018 was selected in this prospective study,and they were divided into two groups randomly: the three-dimensional group and the two-dimensional group,59 cases in each group.The patients in both groups underwent laparoscopic liver resection,while the three-dimensional group was assisted by three-dimensional visualization technology,and the two-dimensional group was assisted by two-dimensional imaging technology.The surgical conditions,length of hospital stay,the degree of ischemia-reperfusion liver injury before and after surgery [alanine aminotransferase(ALT),aspartate aminotransferase(AST),total bilirubin(TBILI)],serum tumor biological indicators [vascular endothelial growth factor(VEGF),acidic fibroblast growth factor(a FGF),basic fibroblast growth factor(bFGF)],incidence of complications were compared between the two groups.After one year’s follow-up,the recurrence rate and survival rate of the two groups were compared.Results In the three-dimensional group,the blood loss during the operation was(402.16±84.27)ml,the amount of blood transfusion during the operation was(1.83±0.21)U,the operation time was(264.22±43.18)min,the hilar occlusion time was(12.16±3.65)min,and the length of hospital stay was(10.33±2.05)d,which were significantly reduced than the two-dimensional group [(546.39±90.06)ml,(2.47±0.54)U,(327.10±61.34)min,(15.90±4.11)min,(12.29±3.04)d],and the differences were statistically significant(P<0.05).One day,three days,and five days after surgery,the serum ALT levels in the three-dimensional group [(349.25±114.05)U/L,(330.51±105.39)U/L,(206.43±55.48)U/L],AST[(340.77±102.39)U/L,(238.36±40.30)U/L(72.07±15.25)U/L],TBILI[(20.91±4.35)mmol/L,(22.36±6.07)mmol/L,(21.33±5.24)mmol/L],VEGF[(44.20±4.22)ng/ml,(31.59±3.56)ng/ml,(20.24±3.07)ng/ml],a FGF[(9.11±1.30)pg/L,(7.25±1.06)pg/L,(4.93±1.15)pg/L],bFGF[(10.50±1.25)pg/L,(7.81±1.14)pg/L,(5.82±1.20)pg/L]were significantly lower than those in the two-dimensional group [(528.04±176.01)U/L,(452.20±150.70)U/L,(261.32±68.06)U/L;(482.01±157.54)U/L,(279.25±51.29)U/L,(89.14±17.09)U/L;(25.08±5.16)mmol/L,(36.27±10.56)mmol/L,(30.90±7.28)mmol/L;(48.26±5.09)ng/ml,(40.30±4.74)ng/ml,(29.75±4.16)ng/ml;(10.53±1.59)pg/L,(8.39±1.18)pg/L,(7.31±1.63)pg/L;(11.97±1.44)pg/L,(9.22±1.58)pg/L,(7.93±1.71)pg/L],the differences were statistically significant(P <0.05).The incidence of complications in the three-dimensional group(8.47%)was significantly lower than that in the two-dimensional group(22.03%),the difference was statistically significant(P<0.05).The one-year tumor recurrence rate in the three-dimensional group(19.64%)was significantly lower than that in the two-dimensional group(36.84%),the difference was statistically significant(P<0.05).Conclusion Compared with two-dimensional imaging technology,three-dimensional visualization technology can provide fast and accurate guidance for LC resection,preserve functional liver volume to the greatest extent on the basis of effective resection,and reduce the risk of complications and improve prognosis.
