Several unusual manifestations such as white bile draining in common bile duct (14 cases) and casual massive bleeding (2 cases ) during and following hepatobiliary and pancreatic operations is reported. These manifestations were in fact signs of hepatic insufficiency. The manners of manifestations of hepatic insufficiency and their treatment are discussed, with a stress that liver-protective treatment and nutritional support are the fundamental modalities.
【 Abstract 】 Objective To explore the effect of gamma-globulin in evaluating hepatic functional reservation in patients with liver tumor. Methods Serum protein electrophoresis (SPE) was performed on 30 patients with liver tumor to get gamma-globulin and preoperative Child-Pugh classification. Then the relations between gamma-globulin and preoperative and postoperative Child-Pugh classification were studied. While with gamma-globulin as evaluating standard, the validity compared with Child-Pugh classification were studied. Results The gamma-globulin was lower in classification A patients 〔（ 21.053 3 ± 6.001 4)% 〕 than that in classification B 〔 (28.800 0 ± 8.672 5)% 〕 before operation. While the gamma-globulin 〔 (21.022 0 ± 5.354 6)% 〕 of classification A patients after operation was also lower than that of classification B/C 〔 (29.556 0 ± 7.698 5)% 〕 . These differences were significant (P ＜ 0.05). With gamma-globulin gt;30% as evaluating standard ， the sensitivity and specificity were 80.00% and 96.00%, respectively. Conclusion Gamma-globulin can reflect hepatic functional reservation in patients with liver tumor. Combining gamma-globulin and Child-Pugh classification can evaluate hepatic functional reservation more objectively.
ObjectiveTo explore the clinical application and recent progress of preoperative liver function evaluation methods.MethodThe literatures about the studies of indexes of preoperative liver function evaluation were summarized and analyzed.ResultsSerological indexes could reflect liver function in many aspects; Indocyanine green clearance test, Child-Pugh and MELD scoring system could improve the accuracy of evaluating liver reserve function; Imaging examination and artificial intelligence (radiomics and deep learning) helped to diagnose the degree of liver fibrosis and accurately measure the volume of functional liver.ConclusionsEach method of preoperative liver function evaluation has certain limitation. It needs comprehensive analysis combined with a variety of evaluation indexes so as to objectively and accurately evaluate liver function and formulate an individualized diagnosis and treatment plan that furthest benefits patients.
ObjectiveTo analyze the risk factors of acute pancreatitis (AP) associated with hepatic dysfunction. MethodsWe collected the clinical data of AP patients from June 2012 to December 2014. According to the hepatic function, patients were divided into normal or mildly abnormal group (A), moderately abnormal hepatic function group (group B) and hepatic failure group (group C). We comparatively analyzed the relationship of abnormal hepatic function with causes (biliary, alcoholic, hypertriglyceridemia, and the others), age, gender, abdominal CT findings, laboratory test results, Ranson scores and the severity of acute pancreatitis bedside index (BISAP). ResultsA total of 117 AP patients were included in the study, including 75 males and 42 females aged from 28 to 71 years with the mean age of (53.21±1.35) years. There were 73 patients with mild AP (MAP), 28 with moderately severe AP (MSAP) and 16 with severe AP (SAP). There were 64 patients in group A, 37 in group B, and 16 in group C, in whom 73 patients were with hepatic dysfunction. The ratio of SAP and MSAP in group C was 75.0%, and MAP was 25.0%. There were 52 patients with bilious AP, 39 with alcoholic AP, 19 with hypertriacylglycerolemia AP, and 7 with others; the difference in causes among the three groups were not significant (P > 0.05). The differences in serum amylase, prothrombin time, white blood cells count, serum creatinine, triglycerides, total cholesterol, hemoglobin, and blood urea nitrogen among the three groups were not significant (P > 0.05). ConclusionsAP associated with hepatic dysfunction or failure may be caused by a various of factors. Whether the changes of serum amylase, prothrombin time, white blood cell count, serum creatinine, triglycerides, total cholesterol, hemoglobin, blood urea nitrogen, and BISAP scores can be the indexes of the judgment of AP with hepatic dysfunction needs more researches. Proper assessment of the related risk factors helps to prevent serious hepatic dysfunction or even failure.
Objective To estimate the relationship between arterial blood ketone body ratio (AKBR) and liver function and to appraise the feasibility of adding AKBR into liver function estimate. MethodsFrom 1994 to 1998, 44 patients with unresectable liver cancer recieved the combined radiochemoembolization with mixed emulsion of phosphorus32 glass microspheres (32PGMS), chemoagent and glycerine or lipiodol, via intraoperative hepatic artery instillation, hepatic artery ligation and operational arterial embolization (HAL+OAE) or transcatheter hepatic artery embolization (TAE). Preoperative and postoperative function and energy change level of the liver were tested by liver function test and AKBR. CT, SPECT, AFP were used to judge the therapy effect; multivariate statistical analysis methods were used to evaluate the correlation between AKBR and liver function. Spearmen rank correlation analysis was used to evaluate whether there was any relationship between AKBR and liver function test, and to evaluate that there was any relationship between AKBR and survival time. ResultsA negative correlation showed between the level of AKBR and liver function. The correlation coefficient of the three level of AKBR before operation and survival time was 0.4409. Conclusion AKBR can well reflect the degree of liver function.
Objective To explore the changes in the serum Cu2+and the indexes for the liver pathology and biochemistry before and after the copper needle retained in the central veins of the rabbit ears. Methods Fortynine New Zealandrabbits were randomly divided into 5 groups: Group A (copper needles retained for 1 d), Group B (3 d), Group C (5 d), Group D (7 d), and Group E (the control group, without any copper needles retained). In each experimental group, there were 10 rabbits, and in the control group there were 9 rabbits. The rabbits in each group were arranged to have their venous blood drawn for determination of theCu2+concentration, and for observation on the changes in the liver biochemicalindexes for 5 times before and after the copper needles were retained in the central veins of the rabbit ears. At the same time, a piece of the liver tissue ineach rabbit was taken for examination of the pathological changes. All the liver samples were given the basic pathological examination; if the liver sample hadsome extraordinary pathological features, the specific pathological examinationwould be given, even using the transmission electron microscope. Results After the copper needles were retained in the central veins of the rabbit ears, the Cu2+concentration increased with the passing time. The concentrations in the groups were 1.40±0.49 μg/ml in Group A, 1.45±0.53 μg/ml in Group B, 2.01±0.40 μg/ml in Group C, 2.38±0.83 μg/ml in Group D, and 1.34±0.45 μg/mlin Group E, respectively. There was a statistically significant difference between Group D and Group E(P＜0.05). There were no significant changes in the ALT and AST levels when compared with those before the copper needles were retained(P＞0.05); however, there was a considerably positive correlation on 1st day (r=0.686, P＜0.05), 5th day (r=0.712, P＜0.05), and 7th day (r=0.768, P＜0.01) when compared with those after the copper needles were retained. The histological examination showed that aseptic inflammation subsided with the time in part of the liver. The Masson staining and the Ag staining showed that there were no obvious changes in the hepatic lobules, with no fibrosis of the liver tissues found under light microscope. Conclusion There are no obvious toxic and side effects on the rabbit liver after the copper needles are retained in its central veins.
目的:了解正常妊娠妇女血清中常用肝功能指标测定结果及变化。方法:分别在早孕（孕10～14周）、中孕（孕20～24周）、晚孕（孕30～34周）及产后（产后12周）四个时期序贯性测定120例正常妊娠妇女血清谷丙转氨酶（ALT）、谷草转氨酶（AST）、γ谷氨酰转移酶（GGT）、乳酸脱氢酶（LDH）、总胆红素（TBIL）、直接胆红素（DBIL）、总蛋白（TP）、白蛋白（ALB）、前白蛋白（PA）的水平并进行比较。结果:ALT、AST在早、中、晚孕及产后各期相对于正常对照均升高（P＜0.01）；TBIL和DBIL在早、中、晚孕均降低（P＜0.01）；TP、ALB随孕期增加逐渐下降,产后回升,到产后12周上升到正常水平（早、中、晚孕P＜0.01,产后P＞0.05）；GGT在孕期中逐渐升高,于晚孕期达最高峰（P＜0.01）,产后稍有下降；LDH在孕早中期无明显变化（P＞0.05）,孕晚期上升,到产后12周仍呈一上升趋势（P＜0.01）；PA在孕早期低于正常对照（P＜0.01）,后随孕期上升,到中孕期后上升到正常（P＞0.05）。结论:本次实验观察到在妊娠期肝功指标ALT、AST、GGT、LDH升高,可能因为孕妇肝脏负荷增加、基础代谢和能量消耗增多、甾体激素水平增高引起。胆红素代谢指标及营养性指标TBIL、DBIL、TP、ALB、PA降低,可能是妊娠期血浆稀释引起。临床诊断妊娠合并肝功能损害时应考虑上述变化。
Twenty-one patients(male 18 cases,femal 3 cases)died of primary liver cancer after operation are reviewed.The liver tumors were located in the right lobe(13 cases),left lobe(3 cases),middle position of liver(4 cases)and hepatic hilum(1 cases).The average diameter of the tumors were 9.0cm.All the patients had suffered from liver cirrhosis and were operated on (most of them partial hepatectomy).The times of death were about 7 days,7-14 days later after operation.The data suggest that causes of death were different from the different stage after operation.The relations between partial hepatectomy and hepatic failure,and the liver cirrhosis and liver regeneration are discussed.
Abstract: Objective To evaluate the protective effects of Ulinastatin on the peri-operative liver and renal function in patients undergoing cardiac surgery for tetralogy of Fallot (TO F). Methods Thirty-eight patients with TOF were divided into Ulinastatin group and control group according to admission sequence, 19 cases in each group.For Ulinastatin group, intravenous Ulinastatin was given with a dosage of 10 000U /kg at 1h before operation, 1h and 24 h after operation. For control group, no Ulinastatin was given. 10 ml fresh urine and 2 ml blood samples were collected before operation, and postoperative 1h, 10h, 24h, 48h and 72h, respect ively. The liver and renal functions were measured. Fluid intake, urine output, chest drainage, dosage of furosemide, durations of mechanical ventilation and intensive care unit ( ICU ) stay were recorded. Results Neither arrhythmia nor low cardiac output syndrome occurred for both groups. No peri-operative death. Compared with control group, dose of furosemide, period of mechanical ventilation were lower, while urine output was higher in Ulinastat in group; the aberrant climax value of urine pro tein and N-acetylglucosam inidase (NAG) were lower in Ulinastatin group (10h post-operat ively, urinem icroalbum in: 65. 2 ± 58. 3mg/L vs. 71. 8 ±58. 9mg/L ; urine transferrin: 5. 8 ± 3. 6mg/L vs. 7. 4 ± 5. 4mg/L ; urine immunoglobulin G: 26. 9±20. 3mg/L vs. 31. 3±23. 3mg/L ; 1h post-operat ively; urine NAG: 61. 4±81. 6U /L vs. 76.1±48. 5 U /L ; P lt; 0. 05) and maintained in shorter period (P lt; 0. 05) , it returned to baseline value at 48h and 72 h post-operatively. The value of alanine aminotransferase (ALT) significantly increased post-operatively at every time points in control group (P lt; 0. 01) , w hile no obvious change in Ulinastat in group (P gt; 0. 05). The increased value of aspartate aminotransferase (AST ) in Ulinastatin group was significantly lower than that in control group (10h post-operat ively: 144. 4±20. 8U /L vs. 202. 7±74. 1U /L ; P lt; 0. 01). The value of AST returned to baseline value at 48h and 72h post-operat ively. Conclusion U linastatin is an effect ive strategy for protecting peri-operat ive liver and renal function of the patients with tetralogy of Fallot and the clinical application of Ulinastatin is safe and effective.
