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.
ObjectiveTo analyze factors affecting post-hepatectomy liver failure (PHLF) of patients with hepatocellular carcinoma (HCC) and explore value of combining albumin-bilirubin (ALBI) score with standardized future liver remnant (sFLR) in prediction of PHLF.MethodsThe clinical data of patients with HCC underwent curative hepatectomy in the Second and the Fifth Departments of General Surgery of the First Hospital of Lanzhou University from January 2016 to June 2018 were retrospectively reviewed. The risk factors of PHLF were identified through the logistic regression, the area under the receiver operating characteristic curve (AUC) was used to analyze the predictive value of the ALBI score, sFLR, or ALBI score×sFLR.ResultsA total of 72 patients with HCC were enrolled, all of them were the Child-Pugh A grade. The incidence of PHLF was 27.78% (20/72) in these 72 patients with HCC, which was 12.96% (7/54) and 72.22% (13/18) in the 54 patients with ALBI- Ⅰ grade and 18 patients with ALBI- Ⅱ grade respectively, the difference was statistically significant (P<0.001). The results of multivariable analysis of PHLF showed that the PLT (OR=0.030, P=0.018), ALBI grade (OR=11.758, P=0.020), and sFLR (OR=0.835, P=0.003) were identified as the independent predictors of PHLF. The AUC for the ALBI score×sFLR in predicting the PHLF was 0.892, it was greater than that of the ALBI score (AUC=0.799) or the sFLR (AUC=0.773).ConclusionCompared with Child-pugh grade, ALBI grade is more accurate in predicting PHLF of HCC patients, and combining ALBI score with sFLR is better than sFLR or ALBI score alone in predicting PHLF of patients with HCC.

Objective To explore favorable factors of reducing incidence of postoperative liver failure after radical resection of Bismuth-Corlette type Ⅳ hilar cholangiocarcinoma in condition of hyperbilirubinemia. Methods All the clinical data of one patient with Bismuth-Corlette type Ⅳ hilar cholangiocarcinoma underwent radical resection in June 2017 in the West China Hospital of Sichuan University were collected. The preoperative total bilirubin level of this patient was 470.3 μmol/L, the patient didn’t receive preoperative biliary drainage. The preoperative jaundice time and cholangitis were calculated accurately. A 3D imaging system for quantitative evaluation of the liver was used to reconstruct the images with contrast-enhanced CT images of this patient. And the total liver volume and the future liver remnant volume (FLRV) were calculated. Finally, 6 months of follow-up were conducted after surgery. Results The exact jaundice time was 20 d and there was no preoperative cholangitis. The postoperative FLRV accounted for about 70%. No postoperative liver failure occurred. No recurrence of tumor and death of patient occurred after 6 months of follow-up. Conclusions Radical resection of hilar cholangiocarcinoma in condition of hyperbilirubinemia is not an absolute contraindication for surgery, but indications should be strictly controlled. For special patient whose jaundice with short duration, no preoperative cholangitis and a high FLRV may be treated with directly radical surgery to prevent for losting the best time of surgery.
ObjectiveTo investigate impact of splenectomy plus pericardial devascularization on liver hemodynamics and liver function for liver cirrhosis patients with portal hypertension. MethodsThe internal diameter, maximum velocity, minimum velocity, mean velocity, and flow volume of portal vein and hepatic artery of 42 cases of liver cirrhosis with portal hypertension were measured by Doppler ultrasonic instrument on day 1 before operation and on day 7 after operation. The free portal pressures at different phases (after open abdomen, after splenic artery ligation, after splenectomy, and after devasculanrization) were read from the disposable pressure sensor. Twenty-four healthy people through physical examination were selected as control. Results① The free portal pressure of liver cirrhosis patients with portal hypertension was decreased from (29.12±1.40) mm Hg after open abdomen to (22.71±1.21) mm Hg after splenic artery ligation, and further decreased to (21.32±1.12) mm Hg after splenectomy, but increased to (22.42±1.15) mm Hg after devasculanrization, the difference was statisticly different (all P < 0.01). ② Compared with the healthy people, for the liver cirrhosis patients with portal hypertension, the internal diameter, maximum velocity, minimum velocity, and flow volume of portal vein were significantly enlarged (all P < 0.01), which of hepatic artery were significantly reduced (all P < 0.01) on day 1 before operation; On day 7 after operation, the internal diameter of portal vein was significantly reduced (P < 0.01), the maximum velocity, minimum velocity, and mean velocity of portal vein were significantly enlarged (all P < 0.01), but the internal diameter of hepatic artery was significantly reduced (P < 0.01), the maximum velocity, minimum velocity, mean velocity, and flow volume of hepatic artery were significantly enlarged (all P < 0.01). For the liver cirrhosis patients with portal hypertension, compared with the values on day 1 before operation, the internal diameter and the flow volume of portal vein were significantly reduced (all P < 0.01) on day 7 after operation; the internal diameter, maximum velocity, minimum velocity, mean velocity, and flow volume of hepatic artery were significantly enlarged (all P < 0.01) on day 7 after operation. ③ The Child-Pugh classification of liver function between before and after surgery had no significant difference (χ2=1.050, P > 0.05). ④ No death and no hepatic encephalopathy occurred, no thrombosis of splenic vein or portal vein was observed on day 7 after surgery. Conclusionsplenectomy plus pericardial devascularization could decrease portal vein pressure and reduce blood flow of portal vein, while increase blood flow of hepatic artery, it doesn't affect liver function.

Objective To investigate the effect of ABO-incompatible liver transplantation on patients with acute hepatic failure. Methods A retrospective review was undertaken on the clinical data of 3 cases （1 case of Budd-Chiari syndrome, 1 case of liver cancer and 1 case of severe hepatitis B were included） undergoing ABO-incompatible liver transplantation for acute hepatic failure. The patients were given quadruple immunosuppression after operation. Results Postoperative complications including pulmonary infection, central pontine myelionlysis and acute rejection was suffered from by the patient of Budd-Chiari syndrome who was then given a positive deal and had survived for more than 14 months. The patient of liver cancer was aggravated by severe infection who died of multiple organ failure on day 13 after operation. The patient with severe hepatitis B was made more severe by acute renal failure whose kidney function was restored with continuous renal replacement therapy. Conclusion The outcome of ABO-incompatible liver transplantation can be improved with refined peri-transplant management and better immunosuppressive strategies. ABO-incompatible liver transplantation should be viewed as an important option in patients with acute hepatic failure awaiting an emergency procedure.
