Surgical Resection Is Superior to TACE in the Treatment of HCC in a Well Selected Cohort of BCLC-B Elderly Patients-A Retrospective Observational Study. Cancers (Basel) 2022; 14:cancers14184422. [PMID: 36139581 PMCID: PMC9496726 DOI: 10.3390/cancers14184422] [Citation(s) in RCA: 2] [Impact Index Per Article: 1.0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 08/29/2022] [Accepted: 09/08/2022] [Indexed: 01/27/2023] Open
Abstract
Hepatocellular carcinoma (HCC) usually develops in cirrhotic liver, with high recurrence rates. However, considering its increasing detection in non-cirrhotic liver, the choice of treatment assumes particular relevance. This study aimed to investigate outcomes of patients among BCLC stages and enrolled for surgical resection (SR) according to a more complex evaluation, to establish its safety and efficacy. A total of 186 selected HCC patients (median age 73.2 yrs), submitted to SR between January 2005 and January 2021, were retrospectively analyzed. Of which, 166 were staged 0, A, B according to the BCLC system, while 20 with a single large tumor (>5 cm) were classified as stage AB. No perioperative mortality was recorded; complications occurred in 48 (25.80%) patients, and all but two were Clavien−Dindo grade I−II. Median follow-up was 9.2 years. Subsequently, 162 recurrent patients (87,1%) were selected for new treatments. Comparable overall survival rates (OS) were observed at 1, 3, 5, and 10 years in 0, A, B and AB stages (p = 0.2). Eventually, the BCLC-B group was matched to 40 BCLC-B patients treated (2015-2021) with TACE. Significant differences in baseline characteristics (p <0.0001) and in OS were observed at 1 and 3 years (p <0.0001); a significant difference was also observed in oncological outcomes, in terms of the absence, residual, or relapse of disease (p <0.05). Surgery might be a valid treatment in HCC for patients affected by chronic liver disease in a condition of compensation, up to BCLC-B stage. Surgical indication for liver resection in case of HCC should be extensively revised.

Evaluation of Plasma Disappearance Rate Indocyanine Green Clearance as a Predictor of Liver Graft Rejection in Donor Brain Death. Transplant Proc 2020; 52:1472-1476. [PMID: 32217011 DOI: 10.1016/j.transproceed.2020.01.084] [Citation(s) in RCA: 5] [Impact Index Per Article: 1.3] [Reference Citation Analysis] [Abstract] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 11/27/2019] [Accepted: 01/02/2020] [Indexed: 10/24/2022]
Abstract
INTRODUCTION There currently exist no quantitative methods to assess graft viability before the donor procurement procedure. In Europe, around 20% of liver grafts evaluated "in situ" by an experienced surgeon are discarded. The aim of this study is to evaluate the use of the plasma disappearance rate indocyanine green (PDR-ICG) clearance in predicting liver graft rejection to avoid this 20% of futile surgeries. OBJECTIVES To evaluate PDR-ICG as a predictor of liver graft rejection in death brain donors compared with the gold standard evaluation by an experienced surgeon. MATERIAL AND METHODS Prospective observational single center study. From March 2017 to July 2019, 29 donors were included in the study, 17 were men and 12 women with a median age of 68 years ± 16.9 years. Donors had an intensive care unit stay of 2 days ± 4 days. PDR-ICG was measured with PICCO2 monitor. Indocyanine green clearance dose was 0.25 mg/kg injected intravenously in the operating room just before donor procurement procedure is initiated. The surgeon was unaware of the PDR-ICG measure until the decision of graft acceptance was taken. Data regarding the donors and biopsy results were included in a prospective database. RESULTS PDR-ICG measure could be obtained in 10 minutes in all of the cases included. The median PDR-ICG obtained was 18%/min (range, 2.4-31%/min). Graft rejection took place in 15 out of the 29 donors. PDR-ICG value was less than 10%/min in 6 of these rejected grafts and less than 15%/min in 10 donors. All donor grafts with PDR-ICG <15% were discarded. The graft had been discarded in 5 donors with a PDR-ICG >15%. CONCLUSIONS In our study a plasma disappearance rate <10 would have identified the grafts that would be rejected, thus avoiding the displacement work and expense of the surgical team. These results should be confirmed in a multicentric study.

Reliability of indocyanine green retention and clearance rates at 15 minutes calculated by dye-dilution cardiac output flowmetry in comparison to blood sampling in patients undergoing hepatic resection. Indian J Gastroenterol 2019; 38:441-449. [PMID: 31802440 DOI: 10.1007/s12664-019-00994-z] [Citation(s) in RCA: 4] [Impact Index Per Article: 0.8] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 05/30/2019] [Accepted: 09/10/2019] [Indexed: 02/04/2023]
Abstract
BACKGROUND The indocyanine green retention rate at 15 min (ICGR15) is a marker of the liver function and is useful for planning hepatectomy. To clarify the ICGR15 and the related clearance value (ICGK) calculated by a dye-dilution cardiac output flowmetry (DCOF), we examined the correlation and clinical significance of the ICGR15 values determined by DCOF and those determined with the conventional blood sampling (BS) procedure. METHODS We extracted liver function parameters, including the ICGR15 modified value and ICGK, and the extent of hepatectomy from the clinical and surgical records of 63 patients with various liver diseases in whom the ICGR15 (actual value), R15m (mean), and K (clearance rate per minute) were measured by DCOF. RESULTS All the patients were classified as Child-Pugh grade A. Hepatic complications were observed in 10 (16%) patients, but there was no mortality. The mean values of ICGR15 determined by BS (R15-BS) and DCOF (R15-DCOF) were 12.2 ± 8.1% and 11.2 ± 8.7%, respectively. The mean R15m determined by DCOF (R15m-DCOF) was 15.7 ± 10.2%. Significant differences were observed between R15-BS and R15-DCOF (1.1 ± 4.8%; p = 0.002) and R15m-DCOF (4.0 ± 5.9%; p < 0.001). The difference between R15-BS and R15m-DCOF was greater than that between R15-BS and R15-DCOF. Correlation between R15-BS and R15-DCOF was significant r = 0.839 (p < 0.001). CONCLUSIONS The ICGR15 measured by DCOF shows comparable reliability and stability to the BS method, which is useful for planning hepatectomy.

Abstract
No worldwide consensus on the assessment tool for liver functional reserve is currently available. The aim of this study was to evaluate the correlation between liver elasticity of both hepatic lobes and liver functional reserve tests. This prospective observational study comprised 40 patients scheduled for hepatectomy. Liver elasticity was assessed by Virtual Touch Quantification (VTQ). The mean VTQ value for the right and left lobes was defined as the mVTQ. Liver functional reserve was measured with technetium-99m-diethylenetriaminepentaacetic acid-galactosyl-human serum albumin scintigraphy as LHL15 and HH15 and the indocyanine green (ICG) excretion test as ICG-R15 and ICG-K. All examinations were measured after biliary decompression confirmed serum a total bilirubin level ≤2 mg/dL. Mean VTQ values were moderately correlated with LHL15 (r = -0.42, p < 0.01), HH15 (r = 0.48, p < 0.01), ICG-R15 (r = 0.53, p < 0.01) and ICG-K (r = -0.61, p < 0.01) values. In conclusion, the liver elasticity determined by VTQ would be a useful predictor of liver functional reserve in patients scheduled for hepatectomy.

Correlation of baseline Portal pressure (hepatic venous pressure gradient) and Indocyanine Green Clearance Test With Post-transarterial Chemoembolization Acute Hepatic Failure. J Clin Exp Hepatol 2019; 9:447-452. [PMID: 31516260 PMCID: PMC6728539 DOI: 10.1016/j.jceh.2018.09.004] [Citation(s) in RCA: 6] [Impact Index Per Article: 1.2] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 04/23/2018] [Accepted: 09/26/2018] [Indexed: 12/12/2022] Open
Abstract
BACKGROUND Liver failure (LF) is a serious complication of transarterial chemoembolization (TACE) in patients with hepatocellular carcinoma (HCC). This could be influenced by the hemodynamic and functional status of the underlying cirrhotic liver. We evaluated baseline hepatic venous pressure gradient (HVPG) and indocyanine green (ICG) clearance as predictive factors for the development of LF in patients with liver cirrhosis undergoing TACE for HCC. METHODS Forty-two patients with cirrhosis and HCC, referred for TACE, were clinically evaluated including the assessment of Child Turcotte Pugh score (CTP), Model for End-Stage Liver Disease (MELD), HVPG measurement, and ICG retention test. Predictors of development of hepatic failure after TACE were determined. RESULTS In our study population, the mean age of the patients was 58 years, with mean CTP of 6.60 ± 1.149 and mean MELD score of 9.57 ± 2.923. The mean HVPG and ICG retention at 15 min was 13.57 ± 4.64 mmHg and 21.571 ± 12.434, respectively. Post-TACE Liver Failure (PTLF within 1 month after TACE) developed in 23.80% patients, whereas 76.19% patients did not have PTLF. The statistically significant preprocedure variables that might predict hepatic failure after TACE using univariate analysis were found to be high CTP, MELD score, ICG retention, HVPG, serum bilirubin, serum creatinine, alfa-fetoprotein levels, large tumor size, and low baseline serum albumin. On multivariate analysis, ICG was an independent factor predictive of hepatic failure after TACE. CONCLUSION Pretreatment evaluation of routine liver function is of fundamental importance before TACE. Baseline ICG retention test (ICG-R15) is a marker indicating the state of liver function in patients undergoing TACE and is an independent predictor for PTLF. Our study concludes that with a cutoff of 25, ICG-R15 has 92.9% accuracy, 90% sensitivity, and 87.5% specificity to predict hepatic failure after TACE.

Abstract
BACKGROUND/AIM Post-Transarterial Chemoembolization (TACE) Liver Failure (LF) is common in patients with Hepatocellular Carcinoma (HCC). No definitive objective parameters predict its occurrence. We assessed the role of Indocyanine Green (ICG) in prediction of post-TACE LF. METHODS Consecutive HCC patients with Child A/B class, categorized as Barcelona Clinic Liver Cancer (BCLC) staging A/B, were included between August 2012 and July 2014. All underwent ICG dynamics: Plasma Disappearance Rate (PDR) was recorded on the day of TACE. Area Under Receiver Operator Characteristic Curve (AUROC) of ICG-PDR was compared with existing prognostic scores: Model for End Stage Liver Disease (MELD), MELD-Na and Child-Turcotte-Pugh (CTP) using Hanley and McNeil method. RESULTS A total of 43 patients, mean age (±sd) 55.1 ± 12.8 years were included; 35 (81.4%) patients were males. Post-TACE LF developed after 17 (28.8%) of 59 procedures. Patients with post-TACE LF had significantly elevated baseline bilirubin (P = 0.006), alkaline phosphatase (P = 0.040) and prolonged international normalized ratio (P = 0.004). The median prognostic scores were higher in patients with post-TACE LF (CTP 7 vs 6; P < 0.001 and MELD 10.5 vs 6.3; P = 0.005). There was no difference in the MELD-Na score. ICG-PDR values were lower in those patients who developed post-TACE LF (7.4%/min vs 10.6%/min; P = 0.008). AUROC for ICG-PDR was 0.72 and a cut-off value <9.25%/min predicted the development of post-TACE LF with a sensitivity, specificity, positive predictive value and negative predictive value of 64.7%, 61.9%, 40.7% and 81.2%, respectively. There were no differences in the AUROC between ICG-PDR and other prognostic markers (Hanley and McNeil, P: 0.244-0.900). CONCLUSION ICG-PDR performs similar to MELD, MELD-Na and CTP score for predicting development of post-TACE LF.

Abstract
AIM The indocyanine green (ICG) finger-piece method (FPM), which allows measurement of the ICG concentration by mounting a light sensor onto a finger, is used to assess liver function. We compared the ICG FPM with the conventional ICG blood sampling method (BSM) in patients with liver disorders. METHODS Ninety consecutive patients simultaneously underwent the ICG BSM and ICG FPM. After ICG administration, blood samples were collected at 5, 10, and 15 min for the ICG BSM. The ICG concentration was measured through the finger piece by an ICG clearance meter. RESULTS Seventy-one patients (78.9%) had Child-Pugh class A liver disease, and 19 (21.1%) had class B or C. The FPM-measured ICG plasma disappearance rate was positively correlated with the BSM-measured values (r = 0.886, P < 0.001). Bland-Altman analysis showed good agreement between the two methods (mean difference, 0.012 ± 0.018). The FPM-measured ICG plasma disappearance rate was positively correlated with the BSM-measured values both in patients with Child-Pugh class A liver disease (r = 0.821, P < 0.001) and class B or C liver disease (r = 0.859, P < 0.001). CONCLUSION The ICG FPM may be an alternative to the ICG BSM for liver function assessment.

Abstract
Gadolinium-ethoxybenzyl-diethylenetriamine pentaacetic acid (Gd-EOB-DTPA), a liver-specific magnetic resonance imaging (MRI) contrast agent, is increasingly used for imaging-based liver function tests. Like indocyanine green and mebrofenin, Gd-EOB-DTPA is taken up by hepatocytes through organic anion-transporting polypeptides 1 (OATP1) B1 and B3 and is then excreted into the bile by multi-drug resistance protein (MRP2). The advantages of Gd-EOB-DTPA-based liver function tests include function measurement integrated in an existing MRI protocol, ability of evaluating segmental liver function, and no ionizing radiation. The approaches based on Gd-EOB-DTPA for function measurement are as follows: measurement of biliary elimination, hepatic parenchymal enhancement, MR relaxometry, and MR perfusion. These approaches have potential value for assessing liver reserve, hepatic fibrosis, non-alcoholic fatty liver disease and so on.

Abstract
AIM To evaluate liver resections without Pringle maneuver, i.e., clamping of the portal triad.
METHODS Between 9/2002 and 7/2013, 175 consecutive liver resections (n = 101 major anatomical and n = 74 large atypical > 5 cm) without Pringle maneuver were performed in 127 patients (143 surgeries). Accompanying, 37 wedge resections (specimens < 5 cm) and 43 radiofrequency ablations were performed. Preoperative volumetric calculation of the liver remnant preceeded all anatomical resections. The liver parenchyma was dissected by water-jet. The median central venous pressure was 4 mmHg (range: 5-14). Data was collected prospectively.
RESULTS The median age of patients was 60 years (range: 16-85). Preoperative chemotherapy was used in 70 cases (49.0%). Liver cirrhosis was present in 6.3%, and liver steatosis of ≥ 10% in 28.0%. Blood loss was median 400 mL (range 50-5000 mL). Perioperative blood transfusions were given in 22/143 procedures (15%). The median weight of anatomically resected liver specimens was 525 g (range: 51-1850 g). One patient died postoperatively. Biliary leakages (n = 5) were treated conservatively. Temporary liver failure occurred in two patients.
CONCLUSION Major liver resections without Pringle maneuver are feasible and safe. The avoidance of liver inflow clamping might reduce liver damage and failure, and shorten the hospital stay.

Indocyanine green retention is a potential prognostic indicator after splenectomy and pericardial devascularization for cirrhotic patients. Hepatobiliary Pancreat Dis Int 2016; 15:386-90.

Abstract
BACKGROUND Splenectomy and pericardial devascularization (SPD) is an effective treatment of upper gastrointestinal bleeding and hypersplenism in cirrhotic patients with portal hypertension. Indocyanine green retention at 15 minutes (ICGR15) was reported to offer better sensitivity and specificity than the Child-Pugh classification in hepatectomy, but few reports describe ICGR15 in SPD. The present study was to evaluate the prognostic value of ICGR15 for cirrhotic patients with portal hypertension who underwent SPD. METHODS From January 2012 to January 2015, 43 patients with portal hypertension and hypersplenism caused by liver cirrhosis were admitted in our center and received SPD. The ICGR15, Child-Pugh classification, model for end-stage liver disease (MELD) score, and perioperative characteristics were analyzed retrospectively. RESULTS Preoperative liver function assessment revealed that 34 patients were Child-Pugh class A with ICGR15 of 13.6%-43.0% and MELD score of 7-20; 8 patients were class B with ICGR15 of 22.8%-40.7% and MELD score of 7-17; 1 patient was class C with ICGR15 of 39.7% and MELD score of 22. The optimal ICGR15 threshold for liver function compensation was 31.2%, which offered a sensitivity of 68.4% and a specificity of 70.8%. Univariate analysis showed preoperative ICGR15, MELD score, surgical procedure, intraoperative blood loss, and autologous blood transfusion were significantly different between postoperative liver function compensated and decompensated groups. Multivariate regression analysis revealed that ICGR15 was an independent risk factor of postoperative liver function recovery (P=0.020). CONCLUSIONS ICGR15 has outperformed the Child-Pugh classification for assessing liver function in cirrhotic patients with portal hypertension. ICGR15 may be a suitable prognostic indicator for cirrhotic patients after SPD.

Abstract
Indocyanine green (ICG) is a water-soluble anionic compound that binds to plasma proteins after intravenous administration. It is selectively taken up at the first pass by hepatocytes and excreted unchanged into the bile. With the development of ICG elimination measurement by spectrophotometry, the ICG retention test has become a safe, rapid, reproducible, inexpensive and noninvasive tool for the assessment of liver function. Clinical evidence suggests that the ICG retention test can enable the establishment of tailored management strategies by providing prognostic information. In particular, this method has been evaluated as a prognostic marker in patients with advanced cirrhosis or awaiting liver transplantation. In addition, it is used as a marker of portal hypertension in cirrhotic patients, as a prognostic factor in intensive care units and for the assessment of liver function in patients undergoing liver surgery. Since recent technology enables ICG-PDR to be measured noninvasively at the bedside, this parameter is an attractive addition to liver function and regional haemodynamic monitoring. However, the current state-of-the-art as concerns this technology remains at a low level of evidence and thorough assessment is required.

Can the model for end-stage liver disease score replace the indocyanine green clearance test in the selection of right hemihepatectomy in Child-Pugh class A? Ann Surg Treat Res 2014; 86:122-9. [PMID: 24761420 PMCID: PMC3994621 DOI: 10.4174/astr.2014.86.3.122] [Citation(s) in RCA: 8] [Impact Index Per Article: 0.8] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 09/02/2013] [Revised: 11/02/2013] [Accepted: 11/15/2013] [Indexed: 12/22/2022] Open
Abstract
Purpose To identify the correlation of the model for end-stage liver disease (MELD) scores with the assessment of the risk of hepatic function after hemihepatectomy in patients with hepatocellular carcinoma (HCC) related to hepatitis B virus (HBV). Methods A case-control study was performed based on data for 141 consecutive patients who underwent curative right hepatic resection between January 2006 and June 2010. Results All patients were Child-Pugh class A. The mean age of the patients was 50 years (range, 29-73 years). The group included 114 men (80.9%) and 27 women (19.1%). The distribution of MELD scores (median, 7; range, 6-14) and indocyanine green retention rate at 15 minutes (ICG-R15) (median, 9.2%; range, 1.1%-19.5%) showed no significant correlation (P = 0.615). Only one perioperative death (0.7%) occurred within 30 days, which was the result of liver failure by hepatic artery dissection during the Pringle maneuver. Hepatic dysfunction occurred in 25 patients (17.7%) after liver resection. In multivariate analysis, male gender, increased HBV DNA level, and elevated serum aspartate transaminase level were significantly related with hepatic dysfunction. Tumor size and satellite nodule were closely associated with tumor recurrence in HBV-related HCC after right hemihepatectomy and satellite nodule was a predisposing factor for mortality in those patients. Conclusion MELD score does not accurately predict hepatic function after right hemihepatectomy in patients with resectable HBV-related HCC. MELD scores were not correlated with the ICG-R15 values in patients with Child-Pugh class A.

Abstract
Background Liver stiffness measurement (LSM) using transient elastography has recently become available for the assessment of liver fibrosis. Whether LSM can predict the functional liver reserve in patients undergoing liver resection is not certain. Aim To correlate liver stiffness measurement (LSM) with indocyanine green (ICG) clearance test and liver biochemistry, and to determine its usefulness in predicting postoperative outcomes in patients undergoing liver resection. Patients and Methods Transient elastography and ICG clearance test were performed pre-operatively in 44 patients with hepatocellular carcinoma. The LSM and ICG retention rate at 15 minutes (R15) were correlated with pre-operative factors and post-operative outcomes. Results There was significant correlation between ICG R15 and LSM. In patients with LSM ≥11 kPa vs <11 kPa, there was significantly higher ICG R15 (17.1% vs 10.0% respectively, p = 0.025). For patients with ICG R15≥10% compared to those <10%, there was significantly higher LSM (12.0 vs 7.6 kPa respectively, p = 0.015). Twenty-eight patients proceeded to resection. There was a significant correlation between LSM and the peak INR after liver resection (r = 0.426, p = 0.024). There was a significant correlation between ICG R15 and the post-operative peak AST level (r = −0.414, p = 0.029) and peak ALT level (r = −0.568, p = 0.002). The operative time was a significant independent factor associated with post-operative complications and peak INR. Conclusion LSM correlated well with ICG R15 in patients undergoing liver resection, and predicted early post-operative complications. Addition of LSM to ICG R15 testing may provide better prognostic information for patients undergoing resection.

Abstract
OBJECTIVE Biochanin A (BCA) is an isoflavone found in red clover and peanuts. Recently, it drew much attention as a promising anticancer and antioxidant. Due to its diversity in pharmacological actions, we were encouraged to investigate its potential as an antifibrotic, elucidating the different molecular mechanisms involved. DESIGN Rats were pretreated with BCA, then injected with carbon tetrachloride (CCl4) for 6 weeks. Changes in liver weight and histology were examined and levels of aspartate and alanine aminotransferases, cholesterol, triglycerides, alkaline phosphatase and total bilirubin measured. To assess hepatic efficiency, indocyanine green was injected and its clearance calculated and albumin, total proteins and insulin-like growth factor-1 expression were measured. Cytochrome P4502E1 activity, cytochrome P4501A1 expression, in addition to sulfotransferase1A1 expression were determined to deduce the effect of BCA on hepatic metabolism. As oxidative stress markers, lipid peroxides levels, reduced glutathione, superoxide dismutase and catalase activities, as well as the total antioxidant capacity, were assessed. Nitric oxide, inducible nitric oxide synthase and cyclooxygenase-2 were used as indicators of the inflammatory response. Signaling pathways involving tumor necrosis factor-alpha, nuclear factor-kappa B, transforming growth factor-beta1, matrix metalloproteinase-9 and alpha-smooth muscle actin were investigated accordingly. Extent of fibrosis was examined by Masson's stain and measuring hydroxyproline levels. RESULTS BCA pretreatment significantly protected against the chronic damage of CCl4. Liver injury, oxidative stress, inflammation and fibrosis markers decreased, while hepatic efficiency improved. CONCLUSION Our findings suggested that BCA administration protects against fibrotic complications, a property that can be contributed to the multimechanistic approach of the drug.

Abstract
AIM To assess the prognostic value of noninvasive indocyanine green (ICG) clearance (ICG-pulse-densitometric method [PDR]) for the outcome of liver grafts after transplantation. METHODS ICG-PDR, hepatic artery resistance index, cardiac output, transaminases, prothrombin time, bilirubin, albumin, hematocrit at 48 to 72 hours after transplantation were analyzed with reference to outcome among 59 liver graft recipients. RESULTS Two grafts were lost at 10 and 88 days during the initial hospitalization. These two patients only differed from the other recipients in the need for packing (1/2 versus 3/57) and degree of hypoproteinemia (46 ± 0 versus 51 ± 7.8 g/L), whereas they had similar ICG-PDR values (16.7%/min and 21.8%/min versus 17.3%/min ± 7.2%/min). Seven patients showed an ICG-PDR ≤ 8.8%/min, a previously identified cutoff for early postoperative complications. These patients versus the other 52 significantly differed in prothrombin index (47.9% ± 15.9% versus 64.3% ± 11.7%, P = .001) and bilirubin (8.3 ± 3.2 versus 3.3 ± 2.9 mg/dL, P = .0001). Early postoperative complications--primary graft nonfunction, hepatic artery thrombosis, or septic shock--responsible for an ICG-PDR ≤ 8.8%/min were observed in 2/7 patients. Interestingly, six cases developed an early (range: 3-15 days) rejection episode. In all the cases rejection suspected by analytical abnormalities was confirmed by liver biopsy. Among the overall series of patients, ICG-PDR significantly correlated with serum albumin (r = 0.345; P = .007), bilirubin (r = -0.514; P = .0001), and hematocrit (r = 0.462; P = .0001) but not with transaminases, prothrombin index, cardiac output, or hepatic artery resistance index. Actuarial 72-month probability of graft survival was 75%. Overall, 14 grafts were lost over a median follow-up of 78 months (range 1-99 m). There were no significant differences among early ICG-PDR values among grafts lost vs retained upon follow-up. CONCLUSION ICG-PDR measured once early after liver transplantation did not offer relevant information to predict individual patient outcomes in the immediate postoperative phase. This lack of prognostic value may have been due to the multiple confounding factors involved in ICG metabolism after liver transplantation.

ScientificWorldJournal 2012; 2012:172575.

Abstract
Purpose. Laparoscopic cholecystectomy has been accepted as an alternative to laparotomy, but there is still controversy regarding the effects of pneumoperitoneum on splanchnic and hepatic perfusion. We assessed the effects of different insufflation pressures on liver functions by using indocyanine green elimination tests (ICG-PDR). Methods. We analyzed 43 patients who were scheduled for laparoscopic cholecystectomy. The patients were randomly allocated to two groups. In Group I, the operation was performed using 10 mmHg pressure pneumoperitoneum. In Group II, 14 mmHg pressure pneumoperitoneum was used. The ICG-PDR measurements were made after induction (ICG-PDR 1) and after the end of the operation (ICG-PDR 2). Serum aspartate aminotransferase (AST), alanine aminotransferase (ALT), and total bilirubin levels were all recorded preoperatively, 1 hour, and postoperative 24 hours after surgery. Results. The ICG-PDR 1 values for Groups I and II were as follows: 26.78 ± 4.2%
per min versus 26.01 ± 2.4%
per min (P > 0.05). ICG-PDR 2 values were found to be 25.63 ± 2.1% per min in Group I versus 19.06 ± 2.2% per min in Group II (P < 0.05). There was a statistically significant decrease between baseline and postoperative ICG-PDR values in Group II compared to Group I (P < 0.05). Statistically, there was an increase between baseline and postoperative 1st-hour serum AST and ALT level in Group II (P < 0.05) compared to Group I. No statistical differences were detected on postoperative 24st-hour serum AST and ALT levels and all the time bilirubin between groups (P > 0.05). Conclusion. In conclusion, the results show that 14 mmHg pressure pneumoperitoneum decreased the blood flow to the liver and increased postoperative 1st-hour serum AST and ALT levels. We think that 10 mmHg pressure pneumoperitoneum is superior to 14 mmHg pressure pneumoperitoneum in laparoscopic cholecystectomy.

Abstract
BACKGROUND The clinical presentation of hepatic artery thrombosis (HAT) post-liver transplantation (LT) varies considerably. Doppler ultrasonography (Doppler US) is the first line investigation, with a diagnostic sensitivity for HAT as high as 92%. Because indocyanine green (ICG) elimination from the blood depends among other factors on the hepatic blood flow, we hypothesized that plasma disappearance rate of indocyanine green (PDR-ICG) can be influenced by the flow in the hepatic artery. Thus, we evaluated the role of PDR-ICG measurement in HAT diagnosis in post-LT patients. PATIENTS AND METHODS Fourteen liver transplant patients with no visible flow in the hepatic artery (Doppler US) were identified. Of the 14, seven patients had HAT confirmed by CT-angiography. The PDR-ICG measurement, an investigation routinely used in our center, was performed in all 14 patients. RESULTS The PDR-ICG in patients with HAT was significantly lower than in patients without HAT (5.8 ± 4.3 vs. 23.8 ± 7.4%/min, p= 0.0009). In patients with HAT, after the revascularization, the PDR-ICG value increased (5.8 ± 4.3 vs. 15.6 ± 3.5%/min, p = 0.006). CONCLUSION The ICG elimination may be an adjunct diagnostic tool in the management of patients with suspected HAT following LT.

Abstract
BACKGROUND Early detection of graft malfunction or postoperative complications is essential to save patients and organs after orthotopic liver transplantation (OLT). Predictive tests for graft dysfunction are needed to enable earlier implementation of organ-saving interventions following transplantation. This study was undertaken to assess the value of indocyanine green plasma disappearance rates (ICG-PDRs) for predicting postoperative complications, graft dysfunction, and patient survival following OLT. METHODS Eighty-six patients undergoing OLT were included in this single-centre trial. ICG-PDR was assessed daily for the first 7 days following OLT. Endpoints were graft loss or death within 30 days and postoperative complications, graft loss, or death within 30 days. RESULTS Postoperative complications of 31 patients included deaths (12 patients) or graft losses. ICG-PDR was significantly different in patients whose endpoints were graft loss or death beginning from day 3 and in those whose endpoints were graft-loss, death, or postoperative complications beginning from day 4 after OLT. For day 7 measurements, receiver operating characteristic curve analysis revealed an ICG-PDR cut-off for predicting death or graft loss of 9.6% per min (a sensitivity of 75.0%, a specificity of 72.6%, positive predictive value 0.35, negative predictive value 0.94). For prediction of graft loss, death, or postoperative complications, the ICG-PDR cut-off was 12.3% per min (a sensitivity of 68.9%, a specificity of 66.7%, positive predictive value 0.57, negative predictive value 0.77). CONCLUSIONS ICG-PDR measurements on postoperative day 7 are predictive of early patient outcomes following OLT. The added value over that of routinely determined laboratory parameters is low.

Abstract
BACKGROUND Intra-abdominal pressure (IAP) and intra-abdominal hypertension (IAH) are associated with significant morbidity and mortality in critically ill patients. Our aim was to assess the effects of IAH on liver function using the noninvasive liver function monitoring system LiMON and to assess the prognostic value of IAP in critically ill patients. METHODS We conducted a retrospective analysis of critically ill patients who were treated in the intensive care unit (ICU). The IAP and indocyanine green plasma disappearance rate (ICG-PDR) measurements were made within 24 hours after admission to the ICU and repeated 12 hours later. Intra-abdominal pressure was measured via a Foley bladder catheter, and ICG elimination tests were conducted concurrently using the LiMON. RESULTS We included 30 critically ill patients (17 women and 13 men aged 28-89 yr) in our analysis. Statistical analysis showed that the baseline IAP values were significantly higher among nonsurvivors than survivors (19.38 [standard deviation; SD 2.08] v. 13.07 [SD 0.99]). The twelfth-hour IAP values were higher than baseline measurements among nonsurvivors (21.50 [SD 1.96]) and lower than baseline measurements among survivors (11.71 [SD 1.54]); the difference between groups was significant (p < 0.001). The baseline ICG-PDR values were significantly lower among nonsurvivors than survivors (10.86 [SD 3.35] v. 24.51 [SD 6.78]), and the twelfth-hour ICGPDR values were decreased in all groups; the difference between groups was significant (p < 0.001). CONCLUSION Our results suggest that measurement of ICG-PDR with the LiMON is a good predictor of the effects of IAP on liver function and, thus, can be recommended for the evaluation of critically ill patients.

Abstract
Standard assays to assess acetaminophen (APAP) toxicity in animal models include determination of ALT (alanine aminotransferase) levels and examination of histopathology of liver sections. However, these assays do not reflect the functional capacity of the injured liver. To examine a functional marker of liver injury, the pharmacokinetics of indocyanine green (ICG) were examined in mice treated with APAP, saline, or APAP followed by N-acetylcysteine (NAC) treatment.Male B6C3F1 mice were administered APAP (200 mg/kg IP) or saline. Two additional groups of mice received APAP followed by NAC at 1 or 4 h after APAP. At 24 h, mice were injected with ICG (10 mg/kg IV) and serial blood samples (0, 2, 10, 30, 50 and 75 min) were obtained for determination of serum ICG concentrations and ALT. Mouse livers were removed for measurement of APAP protein adducts and examination of histopathology. Toxicity (ALT values and histology) was significantly increased above saline treated mice in the APAP and APAP/NAC 4 h mice. Mice treated with APAP/NAC 1 h had complete protection from toxicity. APAP protein adducts were increased in all APAP treated groups and were highest in the APAP/NAC 1 h group. Pharmacokinetic analysis of ICG demonstrated that the total body clearance (Cl(T)) of ICG was significantly decreased and the mean residence time (MRT) was significantly increased in the APAP mice compared to the saline mice. Mice treated with NAC at 1 h had Cl(T) and MRT values similar to those of saline treated mice. Conversely, mice that received NAC at 4 h had a similar ICG pharmacokinetic profile to that of the APAP only mice. Prompt treatment with NAC prevented loss of functional activity while late treatment with NAC offered no improvement in ICG clearance at 24 h. ICG clearance in mice with APAP toxicity can be utilized in future studies testing the effects of novel treatments for APAP toxicity.

Abstract
Liver function reserve estimation is important for selecting the appropriate patients for hepatectomy or ablation of tumors. Many liver function tests have been devised, but the indocyanine green (ICG) clearance test remains the most popular for its simplicity and perhaps accuracy. Compared with the Child-Pugh classification, the ICG retention value at 15 min (ICGR-15) after intravenous injection provides more information. Though a significant difference in ICGR-15 has been observed between patients with Child-Pugh A and B liver function, the hospital mortality rates following partial hepatectomy are not significantly different between the two groups. Yet, ICGR-15 values can differentiate patients with or without hospital mortality. The cutoff values of ICGR-15 for a safe major and minor hepatectomy are 14 and 22%, respectively.

Abstract
Indocyanine green clearance (Cl-ICG) has been used to assess liver function and hepatic blood flow mainly before and after hepatic surgery. Cl-ICG (invasive method) has been reported to be a good marker of early graft function after liver transplantation (LT). The goal of this study was to determine if the indocyanine green plasma disappearance rate (PDR-ICG), measured by a noninvasive technique (LiMON, Impulse Medical System, Munich, Germany), is predictive of complications and graft outcome after LT. From September 2005 to June 2006, 72 LT recipients were included in the study. PDR-ICG was measured daily (from day 0 to day 5 after LT) with a digital sensor after patients were injected with 0.25 mg/kg indocyanine green. A PDR-ICG cutoff level of 12.85%/minute was predictive of the development of a serious postoperative complication. The sequential changes of PDR-ICG enabled us to differentiate 2 groups: (1) patients with early severe complications (hepatic artery thrombosis, primary graft nonfunction, or sepsis) who had a low value of PDR-ICG during the first 5 posttransplantation days (average, 8.8 +/- 4.5%/minute) and (2) patients who developed acute rejection and who had a progressive reduction of PDR-ICG between days 0 and 5 (from 25.5 +/- 4.8 to 10.3 +/- 2.5%/minute; P < 0.002). In conclusion, after LT, PDR-ICG (a noninvasive technique), measured regularly during the first 5 postoperative days, is a safe technique that can predict early postoperative complications.

Abstract
Early diagnosis of graft dysfunction in liver transplantation is essential for taking appropriate action. Indocyanine green clearance is closely related to liver function and can be measured noninvasively by spectrophotometry. The objectives of this study were to prospectively analyze the relationship between the indocyanine green plasma disappearance rate (ICGPDR) and early graft function after liver transplantation and to evaluate the role of ICGPDR in the prediction of severe graft dysfunction (SGD). One hundred seventy-two liver transplants from deceased donors were analyzed. Ten patients had SGD: 6 were retransplanted, and 4 died while waiting for a new graft. The plasma disappearance rate was measured 1 hour (PDRr60) and within the first 24 hours (PDR1) after reperfusion, and it was significantly lower in the SGD group. PDRr60 and PDR1 were excellent predictors of SGD. A threshold PDRr60 value of 10.8%/minute and a PDR1 value of 10%/minute accurately predicted SGD with areas under the receiver operating curve of 0.94 (95% confidence interval, 0.89-0.97) and 0.96 (95% confidence interval, 0.92-0.98), respectively. In addition, survival was significantly lower in patients with PDRr60 values below 10.8%/minute (53%, 47%, and 47% versus 95%, 94%, and 90% at 3, 6, and 12 months, respectively) and with PDR1 values below 10%/minute (62%, 62%, and 62% versus 94%, 92%, and 88%). In conclusion, very early noninvasive measurement of ICGPDR can accurately predict early severe graft dysfunction and mortality after liver transplantation.

Abstract
BACKGROUND Hypovolemia is a common clinical entity in critical patients, and adequate volume replacement therapy seems to be essential for maintaining tissue perfusion. However, it is still uncertain which solution is most appropriate for fluid resuscitation. OBJECTIVE The aim of this study was to investigate the effects of fluid resuscitation with 3.5% polygeline versus 6% hydroxyethyl starch solutions on hemodynamic functions and liver functions assessed with a noninvasive liver function monitoring system (LIMON) in hypovolemic patients. DESIGN This study is a prospective randomized clinical trial. MEASUREMENTS AND RESULTS Thirty hypovolemic patients (intrathoracic blood volume index, <850 mL/m(2)) were randomized into hydroxyethyl starch (mean molecular weight, 130,000 Da) and polygeline (mean molecular weight, 30,000 Da) groups (15 patients each). Indocyanine green plasma disappearance elimination (ICG-PDR) were conducted concurrently using LIMON. A dose of 0.3 mg/kg ICG was given through a cubital fossa vein as a bolus. For fluid resuscitation, 500 mL of colloid was given to the patients. Repeated hemodynamic and ICG-PDR measurements were done at baseline, after infusion, and then at 30 minutes after infusion. RESULTS Intrathoracic blood volume index and systolic, diastolic, and mean blood pressures increased significantly after infusion and remained elevated for 30 minutes after infusion, but there was no significant difference between the 2 groups. Indocyanine green plasma disappearance elimination values were similar in both groups with no significant difference between the two. CONCLUSION Increasing intrathoracic blood volume index and hemodynamic variables by fluid loading is not associated with a significant change in ICG-PDR.

Abstract
BACKGROUND Sepsis is the most frequent infection with high mortality rates in intensive care units (ICUs), and the prediction of outcome is important in the decision-making process. OBJECTIVE To assess the value of the Acute Physiology and Chronic Health Evaluation II (APACHE II) and indocyanin green (ICG) plasma disappearance rate (ICG-PDR) in septic patients. DESIGN Retrospective analysis. MEASUREMENTS AND RESULTS We analyzed 40 septic patients (17 female and 23 male; age range, 20-89 years) who were treated in our ICU. The ICG-PDR measurement and APACHE II score measurement were made within 24 hours after admission to the ICU. Indocyanine green elimination tests were conducted concurrently using the noninvasive liver function monitoring system (LiMON, Pulsion Medical Systems, Munich, Germany). A dose of 0.3 mg/kg ICG was given through a cubital fossa vein as a bolus. RESULTS Statistical analysis showed that ICG-PDR was significantly lower in nonsurvivors (n = 18) than in survivors (n = 22) (mean, 12.1% +/- 7.6%/min; median, 9%/min, vs mean, 21.2% +/- 10.1%/min; median, 20%/min, respectively [P = .004]). The area under the curve as a measure of accuracy was 0.765 for ICG-PDR and 0.692 for APACHE II. Mortality was 80% in patients with ICG-PDR below 8% per minute, and survival was approximately 89% in patients with ICG-PDR above 24% per minute. CONCLUSION The results suggest that ICG-PDR, assessed with a user-friendly noninvasive bedside LiMON device, is a good predictor of survival in septic patients. Sensitivity and specificity of the noninvasive measurement of ICG-PDR on ICU admission was comparable to that obtained by APACHE II scores.

Abstract
BACKGROUND Standard evaluation of patients undergoing hepatic surgery has been through radiological and quantitative determination of liver function. As more complex and extensive surgery is now being performed, often in the presence of cirrhosis/fibrosis or following administration of chemotherapy, it is questioned whether additional assessment may be required prior to embarking on such surgery. The aim of this review was to determine the current knowledge base in relation to the performance of quantitative assessment of hepatic function both pre- and post-operatively in patients undergoing hepatic resectional surgery and liver transplantation. METHODS An electronic search was performed of the medical literature using the MEDLINE database to identify relevant articles with cross-referencing of all identified papers to ensure full literature capture. RESULTS AND CONCLUSIONS The review has identified a number of different methods of dynamically assessing hepatic function, the most frequently performed being through the use of indocyanine green clearance. With the recent and further anticipated developments in hepatic resectional surgery, it is likely that quantitative assessment will become more widely practiced in order to reduce post-operative hepatic failure and improve outcome.

Abstract
Morbidity and mortality from cirrhosis is increasing rapidly in the Western world. Currently the only effective treatment is liver transplantation, an increasingly limited and expensive resource. Consequently, there has been great hope that stem cells may offer new therapeutic approaches in the management of liver disease. In this review we critically appraise the 11 published clinical studies of bone marrow stem cells in liver disease, and focus on the unresolved issues regarding their role. We outline the different mechanisms by which stem cells may impact on liver disease, as well as highlight the importance of the type of stem cell chosen. There are multiple different stem cell populations that have, in rodent studies, been shown to have differing effects on liver regeneration and fibrogenesis/degradation. Thus, choice of cell should reflect the desired or expected mechanism of action. The importance, and methods, of studying the fate of stem cells infused in clinical studies is emphasized as we seek to translate observations in rodents into the clinical setting. Finally, we discuss which cohorts of patients with liver disease would benefit from stem cell therapy, as well as establish minimum criteria for future clinical trials of stem cells.

Non-isotopic tyrosine kinetics using an alanyl-tyrosine dipeptide to assess graft function in liver transplant recipients - a pilot study. Wien Klin Wochenschr 2008; 120:19-24.

Abstract
BACKGROUND Although accurate assessment of liver function in liver transplant recipients is of crucial importance for optimal timing of the procedure and for determining graft viability, none of the many available methods has proven reliable in the clinical routine. Thus, a novel non-isotopic assay of tyrosine kinetics using the tyrosine-containing dipeptide L-alanyl-L-tyrosine (Ala-Tyr) was tested for its clinical feasibility in patients undergoing orthotopic liver transplantation (OLT). METHODS Plasma levels of tyrosine and clearance of tyrosine released after infusion of the dipetide Ala-Tyr were assessed before and one day after OLT in 10 liver transplant recipients with normal graft function, also in three organ donors and in three recipients showing poor graft function. Standard laboratory parameters (e.g. aminotransferases) and the plasma disappearance rate of indocyanine green were also measured. RESULTS Following uneventful OLT, tyrosine plasma levels (before 127 +/- 15 micromol/vs. post-OLT 52 +/- 6 micromol/l, P < 0.05) and kinetics (tyrosine clearance: before 206 +/- 77 ml/min vs. post-OLT 371 +/- 109 ml/min, P < 0.05) were normalized. In cases of severe graft dysfunction, tyrosine kinetics (tyrosine clearance: 238 +/- 61 ml/min) resembled the situation in end-stage liver disease, whereas no such correlation was seen with conventional markers of liver function. Organ preservation had only a minor impact on tyrosine kinetics (n.s.). CONCLUSION OLT rapidly normalizes both the plasma levels and the kinetics of tyrosine. Graft failure is associated with an immediate rise in plasma tyrosine levels and a delay in tyrosine elimination. Our results show that tyrosine clearance using the dipetide Ala-Tyr is a suitable non-isotopic, non-invasive indicator of graft viability in the early postoperative course following OLT.

Abstract
Addition of the middle hepatic vein (MHV) or reconstruction of its tributaries to increase noncongestive graft volume is expected to improve graft function in right liver living donor liver transplantation (LDLT). However, the relationship between noncongestive graft volume and graft function after transplantation has not been clarified and definitive criteria for the reconstruction of MHV tributaries have yet to be established. We analyzed 29 right liver LDLT cases. The noncongestive graft weight was calculated as the total weight of the graft regions drained by hepatic veins reconstructed without postoperative occlusion. We calculated the noncongestive graft-to-recipient weight ratio (ncGRWR) by comparing it to the GRWR. Indocyanine green (ICG) clearance results on days 1 and 3 were significantly correlated with ncGRWR, but not with GRWR. Patients were then divided into 2 groups based on ncGRWR: lower than the median (L-ncGRWR group) and above the median (H-ncGRWR group). ICG clearance in the H-ncGRWR group was significantly better on days 1 and 3. For a different analysis, the patients were again divided into 2 groups, those with and without prolonged cholestasis after transplantation. ncGRWR was significantly lower in patients with prolonged cholestasis, and 7 of 9 patients with an ncGRWR value lower than 0.65 suffered from prolonged cholestasis. Our results demonstrated that the noncongestive volume of a right liver graft has a significant association with early graft function. Further, ncGRWR can play a key role in preoperative determination for additional vein reconstruction of MHV tributaries. When the estimated ncGRWR value with reconstruction of only the right hepatic vein (RHV) (+ inferior right hepatic vein [IRHV]) is less than 0.65, additional vein reconstruction of MHV tributaries should be planned.

Abstract
BACKGROUND Reflux of pancreatic juice into the biliary tract is a well-known risk factor for the development of biliary carcinoma. In this study, we investigated the significance of bile-reflux into the pancreatic ducts in pancreatic carcinogenesis, especially in the development of carcinoma in the main pancreatic duct in hamsters. MATERIALS AND METHODS Syrian hamsters were subjected to three different surgical procedures: cholecystoduodenostomy with dissection of the extrahepatic bile duct on the distal end of the common duct (Model A); cholecystoduodenostomy along with a dissection of the common bile duct (Model B); or simple laparotomy (Model C). The animals then received weekly subcutaneous injections of N-nitrosobis(2-oxopropyl)amine (BOP), for 9 weeks, and were killed for pathological investigation at 16 weeks after the initial BOP administration. RESULTS Pancreas carcinomas developed in 95, 88, and 90% of the Model A hamsters (n = 22), B (n = 24), and C (n = 21), respectively. The induced pancreatic tumors were histologically classified into four types: papillary; tubular; cystic adenocarcinoma; or intraductal carcinoma of the main pancreatic duct consisting of intraductal papillary carcinoma (IPC) and intraductal tubular carcinoma (ITC). The number and the incidence of IPCs induced in Model A hamsters were 24 lesions and 77% and were statistically higher than those in Model B (7 lesions and 29%) and C hamsters (7 lesions and 33%) (P < 0.01). Bile-reflux into the pancreatic ducts was clearly demonstrated in only hamsters of Model A by means of Indocyanine green injection via the portal vein. Proliferative cell nuclear antigen labeling indices of the epithelial cells in the main pancreatic duct in hamsters, with no BOP treatment, were 3.8, 0.8, and 1.1% in Models A (n = 10), B (n = 10), and C (n = 10), respectively, and the difference was statistically significant (P < 0.01). CONCLUSIONS Our findings suggest that bile-reflux into the pancreatic ducts is a significant factor predisposing to the development of IPC of the pancreas through an acceleration of epithelial cell kinetics of the main pancreatic duct.

Abstract
BACKGROUND There is no standard method for predicting remnant liver functional reserve after hepatectomy or for monitoring it in real time. METHODS Indocyanine green (ICG) clearance (K) was measured non-invasively and instantaneously using pulse spectrophotometry before surgery, during inflow occlusion and after hepatectomy in 75 patients who underwent anatomical liver resection for hepatocellular carcinoma (HCC). RESULTS Eight patients (11 per cent) suffered liver failure and one (1 per cent) died in hospital. An estimated remnant K value of 0.090 per min was the cut-off value for liver failure. In a logistic regression model, the estimated remnant K (0.090 per min; P = 0.022) and age (65 years; P = 0.025) were significant predictors of postoperative liver failure. There was a correlation between the estimated and measured post-hepatectomy K, and between the inflow occlusion K and measured post-hepatectomy K (P < 0.001). The cut-off value of less than 0.090 per min for the estimated remnant K resulted in 88 per cent sensitivity and 82 per cent specificity for predicting liver failure. CONCLUSION Perioperative real-time monitoring of ICG-K is useful for evaluating the remnant liver functional reserve before, during and after liver resection for HCC. The estimated remnant K is a significant predictor of liver failure.

Abstract
BACKGROUND Indocyanine green (ICG) elimination is a test widely used to evaluate hepatic functional reserve in patients being assessed for hepatic resection. This study compares a non-invasive liver function monitoring system, the LiMON (Pulsion Medical Systems, Munich, Germany), with serial blood sampling methods. METHODS ICG elimination was measured by the LiMON, spectrophotometry and high-performance liquid chromatography (HPLC) in 20 patients with hepatocellular carcinoma and cirrhosis as part of their preoperative work-up. RESULTS The ICG 15-min retention rates obtained by spectrophotometry and HPLC correlated well (correlation coefficient = 0.91), and there was good agreement between the tests (mean bias = 2.93, 95% confidence interval (CI) = 1.59-4.28). There was a reasonably strong correlation between results obtained with the LiMON and spectrophotometry (correlation coefficient = 0.81), and again there was good agreement between the tests (mean bias = 2.71, 95% CI = 0.19-5.22). On average, 15-min retention rates measured by the LiMON were 2.71 lower than those measured with spectrophotometry. CONCLUSION In patients being assessed for suitability of hepatic resection, the LiMON provides results similar to those obtained by serial blood sampling methods. This is important as techniques of carrying out ICG elimination vary widely between institutions and results are frequently incorporated into scoring systems that are used to determine surgical decisions.

Abstract
The Molecular Adsorbent Recirculating System (MARS) represents an attractive artificial liver support system for the treatment of liver insufficiency. However, neither indications for MARS treatment (i.e., after extended liver resection) nor criteria for discontinuation of therapy have been evaluated. Therefore, we analyzed the clinical data of all our surgical patients who received MARS treatment for acute liver failure (n = 7). The aim of the study was to identify prognostic indicators for survival. Four of 174 patients resected for hepatic malignancy at our institution received a total of 13 MARS treatments. Two additional patients were successfully bridged to orthotopic liver transplantation with seven MARS treatments and one patient was MARS supported after liver transplantation of a steatotic graft with three MARS treatments. Five of the seven patients survived and were dismissed an average of 31 days, ranging from 17 to 47 days, after the final MARS treatment. No technical complications or adverse effects were observed during the MARS treatments. Important prognostic factors for hepatic recovery and survival were indocyanin green plasma disappearance rates greater than 5%/min and an increase in clotting factor V levels after each MARS treatment. We conclude that MARS therapy can be an effective treatment of postoperative liver insufficiency in the surgical hepatobiliary unit.
