ObjectiveTo investigate the effect of indocyanogen green retention rate (ICGR) measurement and Child-Pugh classification of liver function in the preoperative evaluation of hepatic functional reservation. MethodsThe level of ICGR at 15 min (ICGR15) and the percentage of liver fibrosis in 103 patients with liver cancer were measured before hepatectomy, and the Child-Pugh classification of liver function was evaluated before and after the operations, and their connections were analyzed. ResultsAs the rise of Child-Pugh classification of liver function, the percentage of liver fibrosis increased gradually, there were significant differences between any two Child-Pugh classification (Plt;0.05). There was a linear correlation between the ICGR15 and the liver fibrosis percentage (rs=0.960, Plt;0.05). The value of preoperative ICGR15 in patients with postoperative Child-Pugh classification from grade A to grade B or grade B to grade C was gnificantly higher than that in patients with stabilization of Child-Pugh classification before and after operations (Plt;0.05). ConclusionICGR15 combined with Child-Pugh classification can improve the accuracy for the evaluation of preoperative hepatic functional reservation.
Objective To investigate the value of retention rate of indocyanine green at fifteen minutes (ICGR15) during hemihepatectomy for evaluation of residual liver reserve function in patients with primary liver carcinoma. Methods During hemihepatectomy, ICGR15 was tested in 44 patients after the hepatic artery and portal vein of resected side were ligated. Child-Pugh score, Child-Pugh classification, and MELD score before operation were tested. After operation, the liver function condition was estimated. Results The incidence of liver dysfunction was significantly lower in ICGR15lt;10% group (17.9%, 5/28) than that in 10%~15% group (75.0%, 12/16), Plt;0.05. There was no significant difference of Child-Pugh score among normal liver function group, mild insufficiency of liver function group, and severe insufficiency of liver function group （Pgt;0.05）. ICGR15 and MELD score in normal liver function group were statistical lower than those in mild insufficiency of liver function group and severe insufficiency of liver function group (Plt;0.05). ICGR15 was significantly lower in Child-Pugh A group than that in Child-Pugh B group (Plt;0.05). Conclusion Intraoperative residual liver ICGR15 may be more precisely compared with Child-Pugh score in evaluation liver reserve function for the patients with primary liver carcinoma and can help to guide liver resection.
Objective To investigate the dynamic changes of postoperative liver reserve function and laboratory liver function as well as liver volume regeneration, and their potential relationship with short-term clinical outcomes after adult-to-adult living donor liver transplantation (LDLT). Methods The data of 30 recipients underwent LDLT were prospectively collected. The plasma clearance (K) by indocyanine green (ICG) excretive test, liver function test by laboratory methods, liver volume by CT and shortterm (lt;3 months) complications were analyzed. Results The graft recipient body weight ratio (GRBW) was 0.63%-1.43%. The hepatic volume of the recipients in the operation was (638±103) ml, which was smaller than that day 7, 30, and 90 after operation (Plt;0.001), but the hepatic volume at subsequent time point was not different from that at the former time point (Pgt;0.05). The KICG values of recipients among the day 3 〔(0.177±0.056)/min〕, 7 〔(0.183±0.061)/min〕, 30 〔(0.200±0.049)/min〕, and 90 〔(0.209±0.050)/min〕 after operation gradually increased, which was respectively higher than that of recipients before operation (P=0.006, P=0.002, Plt;0.001, and Plt;0.001). Compared with the baseline KICG 〔(0.228±0.036)/min〕 of the donors, the KICG of recipients showed significant variation on day 3 and 7 after operation (P=0.004 and P=0.015), and the KICG of recipients on day 30 and 90 after operation approached the baseline KICG (P=0.355 and P=0.915). The recipients were divided into good liver function group (n=23) and poor liver function group (n=7) according to total serum bilirubin on day 14 after operation. The KICG significantly dropped compared with the recipients of good liver function group on day 3 after operation (P=0.001). Conclusions The liver volume regenerates dramatically on day 7 after operation for the recipients. The ICG excretivetest shows that volume recovery occurs much more gradually than the recovery of function in the recipients. The ICG excretive test is a more reliable indicator of graft function and subsequent graft outcome early after LDLT.
Objective To evaluate the effect of pulse dye-densitometry by indocyanine green test (PDD-ICG)on the assessment of hepatic function reserve. MethodsSeventy-five hepatic carcinoma patients aimed to accept hepatectomy from March 2007 to February 2008 at West China Hospital were prospectively included in this study.Patients were grouped by dysfunction grade of hepatic function and the indexes before operation were compared.Furthermore, patients were grouped by K and R15 value to compare the moderate and severe liver dysfunction ratio, respectively. ResultsSixty cases manifested slight liver dysfunction,12 cases manifested moderate liver dysfunction,and 3 cases manifested severe liver dysfunction(the latter was took into moderate group due to the cases were too few).The difference of Child-Pugh score and common liver function examination indexes such as PT and INR before operation was not significant betweentwo groups(P＞0.05).ButPDD-ICG experiment indexes(K and R15)were remarkable different betweentwo groups(P＜0.05).The patients were divided into two groups according to K and R15 value,respectively.The rate of moderate and severe liver dysfunction was significant different between K＜0.158/min groupand K≥0.158/min group(47.1% vs. 12.1%,P＜0.05),and likewise moderate and severe liver dysfunction was significant different between R15≤10% group and R15＞10% group(15.9% vs.41.7%,P＜0.05）. ConclusionPDD-ICG is an effective and easyto evaluate hepatic function reserve of patient undergone hepatectomy.Therefore,it may give clinical instruction to predict and avoid the liver dysfunction after operation.
【Abstract】Objective To look for a feasible way to evaluate hepatic reserve function completely by retention rate of indocyanine green at 15 minutes （ICGR15）and Child-Pugh classification supplemented by hepatic clearance of D-sorbitol (CLh-s). Methods The ICGR15, Child-Pugh classification and CLh-s were examined in 186 patients with liver cirrhosis. Relations between CLh-s and operative complications were further studied when ICGR15 and Child-Pugh classification was superposed. ResultsThe superpositions of ICGR15 (40% being boundary) and Child-Pugh classification was centralized between Child-Pugh B and C. ICGR15 of 17 examples were higher than 40% in 63 examples of Child-Pugh B. Eight examples of them had some complications, CLh-s=(584.52±98.27) ml/min (CLh-s＜700 ml/min), while 9 examples of them had no complications, CLh-s=(801.25±75.04) ml/min (CLh-s＞700 ml/min). Conclusion The CLh-s could be interrelated with operative complication, and it is considered as an effective supplement to ICGR15 and Child-Pugh classification for the evaluation of hepatic reserve function, CLh-s (700 ml/min being boundary) could be used to predict operative complication, to evaluate hepatic reserve function effectively, and to provide the basis for choosing the right time for operation.
Objective To investigate the changes of indocyanine green retention rate at 15 minutes (ICGR15) of autologous peripheral blood CD34+ hematopoietic stem cells transplantation in end-stage liver disease (end-stage liver, disease, ESLD) patients with different Child-Pugh grades during before and after transplantation of 3, 6, 12, 36, and 60 months. Methods The CD34+ hematopoietic stem cells transplantation were performed in 60 cases of advanced liver cirrhosis with different Child-Pugh grades who were ineffectively treated with strictly conservative treatment and complied with the criterion of liver transplantation. The ICGR15 were performed before transplantation and in 3, 6, 12, 36 and 60 months after transplantation. And the results of each time point in each Child-Pugh classification group were compared, and the rate of change of ICGR15 value were compared between each Child-Pugh classification group. Results The ICGR15 values of the Child-Pugh grading groups all decreased with time. In Child A group, there were respectively significant differences between the 6 months, 12 months, 36 months, and 60 months groups after transplantation and preoperative and 3 months groups after transplantation (P<0.05), but there was no significant difference between preoperative and 3 months group after transplantation (P>0.05), and there was significant difference between the 12 months and the 60 months group after transplantation (P<0.05). As same as Child A group, there were also significant differences between that time groups in the Child B group (P<0.05), but there were also significant differences between the 3 months group after transplantation and preoperative (P<0.05), and there were respectively significant differences between the 6 months and 12 months, 36 months, and 60 months group after transplantation in the Child B group (P<0.05). Also in the Child C group, there were significant differences between that time groups (P<0.05), but there was no significant difference between preoperative and 3 months group after transplantation (P>0.05), and there were respectively significant differences between the 6 months and 12 months, 36 months, and 60 months group after transplantation (P<0.05). There was no significant difference in the rate of ICGR15 between Child-Pugh classification groups. Conclusion Autologous peripheral blood CD34+ hematopoietic stem cells transplantation can effectively improve the liver function reserve capacity of ESLD patients and improve the safety of operation for a long time.
