Evaluation of liver function for hepatic resection for hepatocellular carcinoma in the liver with damaged parenchyma

Background

Liver functional parameters, including the Child—Pugh score and indocyanine green clearance (ICG), and volumetric parameters influencing postoperative liver function were evaluated with the aim of obtaining standardardized criteria for selecting patients for, and deciding the extent of, hepatectomy for hepatocellular carcinoma (HCC).

Materials and methods

The study population consisted of 120 patients with HCC undergoing hepatic resection excluding those with more than 3000 ml of intraoperative bleeding. Patients were classified as grades A, B, or C on the basis of, respectively, a Child—Pugh score of 5 or 6, 7-9, or ≥10 and were assigned to group D (postoperative liver dysfunction) or group N (no complication). Postoperative complications included massive ascites, pleural effusion, or hyperbilirubinemia. For each grade, the standardized estimated liver remnant ratio (STELR) was determined as the ratio of the liver remnant volume (estimated by computerized tomography) to the standardized total liver volume (STLV), estimated from the body surface area using the equation: liver volume [cm³] = 706 × body surface area [m²] + 2.4. The ICG retention rate at 15 min after injection (ICGR15) was then plotted against the STELR for each grade and a demarcation line separating patients in groups N and D was determined statistically by discriminant analysis.

Results

For grade A patients, the equation of the demarcation line was ICGR15 = 27.5 × STELR + 1.9 (Wilks’ Lambda: 0.667, P < 0.001), indicating that, for safe hepatic resection in patients with an ICGR15 of 10%, the STELR should be greater than 0.29. In contrast, for grade B patients, the equation was ICGR15 = 72 × STELR − 22.1 (0.589, P < 0.001), indicating that, in patients with a 10% ICGR15, the STELR should be greater than 0.44, a larger value than in grade A patients. The number of grade C patients was too small for analysis.

Conclusions

By combining the Child—Pugh score, ICG clearance, and liver volumetric parameters, criteria for the selection of patients for hepatic resection for HCC were established.     

吲哚菁绿清除试验在肝癌术前评估肝脏储备功能的临床应用

【摘要】 目的 探讨吲哚菁绿清除试验(ICGR15)在肝癌术前评估肝储备功能的临床应用价值。方法〓回顾性分析2012年6月至2013年7月我院63例肝细胞癌手术病人临床资料,根据术前ICGR15分组,对比不同组别术后肝功能恢复情况,并对相关临床资料进行多因素非条件Logistic回归分析。结果〓ICGR15≥10%组术后肝功能代偿不全的发生率显著高于ICGR15<10%组(68.2% vs 19.5%,P<0.05)。Child-pugh评分中B级组ICGR15分值较A级组显著升高(19.01%±11.14% vs7.57%±8.34%,P<0.05);ICGR15分值与Child-pugh评分有较好的相关性(P<0.05,r=0.313)。ICGR15预测肝癌术后肝功能不全的特异度为82.5%,明显高于OGTT(P<0.05),而敏感度为65.2%,特异度为82.5%,阳性预测值为68.2%,阴性预测值为80.5%,但与OGTT比较均无统计学差异(P>0.05)。ICGR15与术后肝功能恢复情况有相关性(P<0.05,r=0.434),而OGTT与术后肝功能恢复情况无明显相关性(P>0.05)。Logistic回归分析示ICGR15、脉管癌栓、术中出血量以及术后其他相关并发症是发生术后肝功能代偿不全的独立危险因素。结论 ICGR15是肝癌术前评估肝脏储备功能较理想的临床指标,能较准确预测术后肝功能恢复情况。     

Prediction of postoperative hepatic dysfunction after cardiac surgery in patients with chronic congestive heart failure

Objective  Chronic congestive liver dysfunction in advanced valvular disease remains an important co-morbidity in open heart surgery. The objective of this study was to explore the prognostic value in patients with severe valvular disease associated with congestive liver dysfunction. Methods  From 1997 to 2004, a total of 63 patients who had valvular disease with moderate or severe tricuspid regurgitation were studied. In addition to the indocyanine green retention rate at 15 min (ICG15) and the Child-Pugh score, we measured serum total bilirubin (T-bil), asparate aminotransferase (AST), alanine aminotransferase (ALT), cholinesterase (ChE), albumin (Alb) concentration, and prothrombin time. We compared these preoperative factors with postoperative liver dysfunction and mortality and attempted to develop a new liver function score. Results  There were eight in-hospital deaths (13%). Seventeen patients had postoperative liver dysfunction. The univariate analysis indicated there were significant differences in preoperative T-bil, Alb, ChE, ICG15, and Child-Pugh score between the patients with and without liver dysfunction. Multivariate logistic regression analysis also identified preoperative T-bil as a significant indicator of postoperative liver dysfunction and preoperative ChE as a predictor of mortality. Based on these findings, we introduced a liver function score to predict postoperative dysfunction and death. Conclusion  In addition to preoperative ChE, T-bil and Alb appeared to be valuable for producing obtainable prognostic information regarding postoperative liver dysfunction in patients with severe valvular disease. A new liver score, including T-bil, ChE, and Alb, is proposed for predicting postoperative hepatic dysfunction and outcome.     

Preoperative regional maximal removal rate of technetium-99m-galactosyl human serum albumin (GSA-Rmax) is useful for judging the safety of hepatic resection

BACKGROUND: For hepatic resection, the preoperative estimation of hepatic functional reserve in the predicted remnant liver may be more important than that of the entire liver. We evaluated the maximal removal rate of technetium-99m-galactosyl-human serum albumin (GSA-Rmax) in the remnant. METHODS: One hundred and seventy-eight patients were admitted for elective hepatectomy. Conventional liver function, and 15-minute retention rate of indocyanine green (ICGR15) were carried out preoperatively. The GSA-Rmax was calculated according to a radiopharmacokinetic model; then we used the single photon emission computed tomography images to calculate the regional GSA-Rmax in the predicted residual liver (GSA-RL), depending on the operative procedures. The volume of the predicted residual liver (LV-RL) was calculated on the basis of computed tomography images. RESULTS: The preoperative LV-RL correlated well with the GSA-RL in patients with normal liver; however, there was no such correlation in those with chronic hepatitis or cirrhosis. All of 7 postoperative hyperbilirubinemia occurred in the patients with GSA-RL < 0.15. Two patients died of postoperative liver failure 1 to 2 months after the operation. These 2 patients had GSA-RL values of 0.078 and 0.090, respectively, and severe discrepancies between the GSA-Rmax in the remnant liver and ICGR15. CONCLUSIONS: We concluded that GSA-RL may be useful for determining the procedure of hepatectomy and that the value should be maintained at greater than 0.15 to avoid postoperative hyperbilirubinemia or hepatic failure.

体外肝切除联合剩余肝脏自体移植治疗特殊位置肝癌

Ex-vivo liver resection is developed based on liver transplantation and technique of cold preservation of organs.It overcomes the shortcomings of time limit of warm ischemia and high technique demand of hepatectomy of tumors located at critical sites.A 58-year-old woman with hepatocellular carcinoma located close to the middle hepatic vein combined with invasion of right hepatic vein was admitted to Southwest Hospital.Because of the critical tumor site,conventional liver resection Wag assessed as impossible.Ex-vivo liver resection was performed,and a vessel patch from an organ wag harvested to repair the defect of the right hepatic vein,and then the liver remnant was subsequently autotransplanted.After operation,the patient recovered smoothly without venous outflow complication.Bile leakage wag observed on postoperative day 23,and the maximnm volume of intraperitoneal drainage wag 200 ml per 24 hours.Endoscopic nasobiliary drainage Was performed and the volume of intraperitoneal drainage gradually decreased to none.Liver function of the patient was back to normal and with no tumor recurrence at the end of 6 months of follow up.Ex-vivoliver resection is beneficial to patients with centrally located hepatocellular carcinoma with the involvement of hepatic vein and inferior vena cava.     

Assessment of hepatic reserve for indication of hepatic resection: how I do it

Background/purpose Hepatic resection may result in liver failure in patients with cirrhotic livers. Preoperative evaluation of liver function in cirrhotic patients, to prevent postoperative liver failure, is very important.Methods Sixteen patients with hepatocellular carcinoma in cirrhotic livers were enrolled in this study. Liver function was determined quantitatively by monoethylglycinexylidide (MEGX) formation from the metabolism of lidocaine. The whole liver volume and tumor volume were measured by computed tomographic volumetry. The volume of resected liver was recorded by water displacement. The relationship between liver function and remnant liver volume was determined.Results A relationship between the percentage remnant liver volume and ratio of MEGX formation after hepatectomy was found. The regression equation was: (postoperative MEGX formation/preoperative MEGX formation) × 100% = (0.688 × percentage remnant liver volume + 0.179) × 100% (r ² = 0.49). A relationship between MEGX formation after hepatectomy and the international ratio (INR) of prothrombin time was also found. The regression equation was INR = 1.99 – 0.01 × MEGX (r ² = 0.30).Conclusions Post-hepatectomy liver function can be estimated for an individual patient by the appropriate regression equations. Prevention of post-hepatectomy liver failure for patients with cirrhotic livers is feasible.

Usefulness of measuring hepatic functional volume using Technetium-99m galactosyl serum albumin scintigraphy in bile duct carcinoma: report of two cases

We report the usefulness of measuring functional liver volume in two patients undergoing hepatectomy. Case 1 involved a 47-year-old man with hepatitis B virus infection. The indocyanine green test retention rate at 15 min (ICGR15) was 14%. Liver uptake ratio (LHL15) by technetium-99 m galactosyl human serum albumin (^99mTc-GSA) liver scintigraphy was 0.91. The patient displayed hilar bile duct carcinoma necessitating right hepatectomy. After preoperative portal vein embolization (PVE), future remnant liver volume became 54% and functional volume by ^99mTc-GSA became 79%. Although the permitted resected liver volume was lower than the liver volume, scheduled hepatectomy was performed following the results of functional liver volume. Case 2 involved a 75-year-old man with diabetes. ICGR15 was 27.4% and LHL15 was 0.87. The patient displayed bile duct carcinoma located in the upper bile duct with biliary obstruction in the right lateral sector. The right hepatectomy was scheduled. After PVE, future remnant volume became 68% and functional volume became 88%. Although ICGR15 was worse as 31%, planned hepatectomy was performed due to the results of functional volume. In the liver with biliary obstruction or portal embolization, functional liver volume is decreased more than morphological volume. Measurement of functional volume provides useful information for deciding operative indication.
