Factors related to pleural effusion following hepatectomy for primary liver cancer

BACKGROUND: Pleural effusion frequently complicates hepatectomy and multiple factors contribute to its development following hepatectomy for primary liver cancer. The purpose of this study was to evaluate these factors. METHODS: From March 2003 to May 2005, 228 consecutive patients with primary liver cancer underwent hepatectomy in our department were evaluated retrospectively to identify factors related to postoperative pleural effusion. RESULTS: Among the 228 patients, postoperative pleural effusions arose in 58 (25.4%). Univariate analysis showed significant differences in postoperative ascites, subphrenic collection, Pringle manoeuvre length, drainage amount on postoperative day 1, albumin level on postoperative day 7, alanine aminotransferase (ALT) level on postoperative days I and 3, prealbumin level on postoperative days 3 and 7, and tumor size (P<0.05). Ordinal regression analysis revealed that subphrenic collection, drainage on postoperative day I and ALT plus prealbumin on postoperative days I and 3 were statistically significantly related to postoperative pleural effusion (P<0.05). CONCLUSION: Subphrenic collection and operative injury to the liver appeared to be significantly related to pleural effusion after hepatectomy for primary liver cancer.

Hepatectomy for patients with huge primary liver cancer in Hubei Province of China

Objective: To discuss the safety and feasibility of hep-atectomy for huge primary liver cancer (PLC).Methods: The effect of resection of huge PLC was ex-amined retrospectively. Some problems in resection ofhuge PLC were discussed.Results: Of 375 patients with huge PLC undergoinghepatectomy, 11 (2.9%) died in one month after op-eration. The 1-, 2-, 3-, 5- and 10-year survivalrates of the patients were 63.3%, 45.6%, 34.7%,16.5% and 1.8%, respectively. The effect of prolong-ing survival time was significant.Conclusion: Hepatectomy for huge PLC is safe, feasi-ble, and effective.

Risk factors for post-hepatectomy liver dysfunction in primary liver cancer patients with concurrent hepatic schistosomiasis and chronic hepatitis

Objective:The purpose of this study was to analyze risk factors for development of post-hepatectomy liver dysfunction in primary liver cancer(PLC)patients with concurrent hepatic schistosomiasis and chronic hepatitis.Methods:A retrospective analysis of 73 PLC patients with concurrent hepatic schistosomiasis and chronic hepatitis,of which 16 patients developed liver dysfunction(persistent ascites or pleural effusion or occurrence of liver-related potentially fatal complications)following hepatectomy,was performed.After clinical characteristics were recorded,preoperative liver function parameters and surgery-related parameters in these patients were assessed.Seventeen potential risk factors for post-hepatectomy liver dysfunction were identified.The association between these potential risk factors and post-hepatectomy liver dysfunction then was analyzed.Results:Univariate analysis showed that liver cirrhosis,intraoperative blood loss,and preoperative total bilirubin were associated with the development of post-hepatectomy liver dysfunction.Multivariate logistic regression analysis of these three factors revealed that intraoperative blood loss≥600 mL and cirrhosis were two independent risk factors for post-hepatectomy liver dysfunction in PLC patients with concurrent hepatic schistosomiasis and chronic hepatitis.Conclusion:Keeping intraoperative blood loss below 600 mL can help avoid the development of post-hepatectomy liver dysfunction in liver cancer patients with concurrent hepatic schistosomiasis and chronic hepatitis.For patients with concomitant liver cirrhosis,every effort should be made to minimize potential liver function impairment induced by other adverse factors.

Impact of Operative and Peri-operative Factors on the Long-term Prognosis of Primary Liver Cancer Patients Undergoing Hepatectomy

This study examined the impact of the operative and peri-operative factors on the long-term prognosis of patients with primary liver cancer undergoing hepatectomy. A total of 222 patients with primary liver cancer who underwent hepatectomy were followed up from January 1986 to December 2010 at Chinese PLA General Hospital. The post-operative complication rate was 14.0% for all cases, 13.7% for hepatocellular carcinoma（HCC）, 10.0% for cholangiocarcinoma. The 1-, 3-, 5- and 10-year overall survival rates in patients with primary liver cancer after resection were 76.6%, 57.6%, 41.4%, and 21.0%. The survival rates were significantly higher in the HCC group than in the cholangiocarcinoma group（P=0.000）, in the non-anatomical resection group than in the anatomical resection group（P=0.005）, in the female group than in the male group（P=0.002）, in patients receiving no blood transfusion than in those who were given intra-operative blood transfusion（P=0.000）, in patients whose intra-operative blood loss was less than 400 m L than in those who intra-operatively lost more than 400 m L（P=0.000）. No significant difference was found in the survival rate between the HBs Ag-positive group and the HBs Ag-negative group（P=0.532）. Our study showed that anatomical resection, blood loss and blood transfusion were predictors of poor survival after hepatectomy for primary liver cancer patients, and concomitant hepatitis B virus infection bore no relation with the post-resection survival.

Complete or partial split in associating liver partition and portal vein ligation for staged hepatectomy: A systematic review and meta-analysis

BACKGROUND Associating liver partition and portal vein ligation for staged hepatectomy(ALPPS)has been adopted by liver surgeons in recent years.However,high morbidity and mortality rates have limited the promotion of this technique.Some recent studies have suggested that ALPPS with a partial split can effectively induce the growth of future liver remnant(FLR)similar to a complete split with better postoperative safety profiles.However,some others have suggested that ALPPS can induce more rapid and adequate FLR growth,but with the same postoperative morbidity and mortality rates as in partial split of the liver parenchyma in ALPPS(p-ALPPS).AIM To perform a systematic review and meta-analysis on ALPPS and p-ALPPS.METHODS A systematic literature search of PubMed,Embase,the Cochrane Library,and ClinicalTrials.gov was performed for articles published until June 2019.Studies comparing the outcomes of p-ALPPS and ALPPS for a small FLR in consecutive patients were included.Our main endpoints were the morbidity,mortality,and FLR hypertrophy rates.We performed a subgroup analysis to evaluate patients with and without liver cirrhosis.We assessed pooled data using a random-effects model.RESULTS Four studies met the inclusion criteria.Four studies reported data on morbidity and mortality,and two studies reported the FLR hypertrophy rate and one study involved patients with cirrhosis.In the non-cirrhotic group,p-ALPPS-treated patients had significantly lower morbidity and mortality rates than ALPPStreated patients[odds ratio(OR)=0.2;95%confidence interval(CI):0.07–0.57;P=0.003 and OR=0.16;95%CI:0.03-0.9;P=0.04].No significant difference in the FLR hypertrophy rate was observed between the two groups(P>0.05).The total effects indicated no difference in the FLR hypertrophy rate or perioperative morbidity and mortality rates between the ALPPS and p-ALPPS groups.In contrast,ALPPS seemed to have a better outcome in the cirrhotic group.CONCLUSION The findings of our study suggest that p-ALPPS is safer than ALPPS in patients without cirrhosis and exhibits the same rate of FLR hypertrophy.

Prevention and management of pleural effusion following hepatectomy in primary liver cancer

Postoperative pleural effusion occurs frequently after hepatectomy. The risk factors, prevention and management of postoperative pleural effusion in patients with primary liver cancer (PLC) who have undergone hepatectomy and the value of the argon beam coagulator (ABC) for the prevention of pleural effusion are studied. METHODS:A total of 523 patients with PLC at our institution who had had right hepatectomy from July 2000 to June 2004 were studied retrospectively. Comparative analysis was made to identify the factors contributing to postoperative pleural effusion and the efficacy of various managements. RESULTS:Of the 523 patients whose livers were dissociated using argon beam cutting and/or coagulation, 20(3.8%) developed pleural effusions;whereas in the other 467 patients underwent hepatectomy with suture ligation of the diaphragmatic secondary wound surface during the same period, 49(10.5%) had pleural effusion (P<0.01). The factors contributing to postoperative pleural effusion included subphrenic collection, postoperative hepatic insufficiency with ascites, duration of hepatic occlusion and underlying cirrhosis. CONCLUSIONS: Dissociation of the liver by argon beam cutting and/or coagulation can save suture ligation of the diaphragmatic secondary wound surface and may also prevent postoperative pleural effusion. Pleural drainage using an indwelling central-venous-catheter (CVC) in the pleural cavity is safe and efficacious.

Hepatectomy in the treatment of very big primary liver cancer: report of 86 cases

Objective: To study the indications for resection ofvery big primary liver cancer and the operative re-sults.Methods: From January 1985 to June 1996, 86 pa-tients with very big primary liver cancer (≥15cm indiameter) underwent hepatectomy in our hospital.The volume of bleeding and blood transfusion wasrecorded during the operation. After the operation,the draining quantity from their abdominal cavities,and the days of transfusion and hospitalization wererecorded. The occurrence of complications and sur-vival time of the patient were followed up.Results: The postoperative mortality was 3.48% andthe occurrence rate of complications was 31.40%, whichwas significantly correlated with preoperative lowerlevel of serum albumin or the elevated γ-globulin lev-el and the amount of resected liver tissue. But their liverfunction before operation was fairly good, the 1-, 3-and 5-year survival rates after hepatectomy were58.2%, 35.7% and 17.64%.Conclusions: Patients with very big primary liver can-cer, should be subjected to hepatectomy if their liverfunction before operation are normal and the marginsare distinct between the tumor and liver tissues. Afterthe operation, other treatments are suitable for goodeffects.

A Clinical Investigation into the Factors Influencing the Prognosis of Patients with Primary Liver Cancer after Hepatectomy

Objective To explore the factors influencing the prognosis of patients with primary liver cancer(PLC) after hepatectomy on purpose to provide the preventive measures for improving the long-term effect.Methods All of the 189 patients who underwent hepatectomy with PLC from May,1994 to January,1998 were included by reviewing their clinical pathological characteristics and treatments. Totally, 22 factors contributed to the long-term survival rate(SR)and the disease-free SR were analysed . All patients were followed up at least 5 years. Results The 3- and 5-year cumulative SRs in the total group were 63% and 45% respectively. The 3- and 5-year SRs and disease-free SRs in the curative resection (CR) group (n=162) were 67%,47%,and 45% and 26% respectively. It was showed that the way by which a tumor was found, tumor size, portal thrombi, satellite nodule, cirrhosis type, TNM stage, tumor envelope, recurrence and treatment, vascular exclusion and transfusion, differentiation grade and CR were prognostic factors by individual variable analysis. A multivariable analysis showed that CR , tumor size and reoperation were significant factors associated with the prognosis. Conclusion The type of CR and tumor size are determinants influencing the prognosis. Early diagnosis of small carcinoma and CR as soon as possible is essential to improving the prognosis of PLC. Avoiding transfusion and controlling the progress of cirrhosis are expected to improve the disease-free SR.

Micrometastasis in surrounding liver and the minimal length of resection margin of primary liver cancer

AIM： To describe the distribution of micrometastases in the surrounding liver of patients with primary liver cancer （PLC）, and to describe the minimal length of resection margin （RM） for hepatectomy. METHODS： From November 2001 to March 2003, 120 histologically verfied PLC patients without macroscopic tumor thrombi or macrosatellites or extrahepatic metastases underwent curative hepatectomy. Six hundreds and twenty-nine routine pathological sections from these patients were re-examined retrospectively by light microscopy. In the prospective study, curative hepatectomy was performed from November 2001 to March 2003 for 76 histologically verfied PLC patients without definite macroscopic tumor thrombi or macrosatellites or extrahepatic metastases in preoperative imaging. Six hundreds and forty-five pathological sections from these patients were examined by light microscopy. The resected liver specimens were minutely examined to measure the resection margin and to detect the number of daughter tumor nodules, dominant lesions, and macroscopic tumor thrombi inside the lumens of the major venous system. The paraffin sections were microscopically examined to detect the microsatellites, microscopic tumor thrombi, fibrosis tumor capsules, as well as capsule invasion and the distance of histological spread of the micrometastases. RESULTS： In the retrospective study, 70 micrometastases were found in surrounding liver in 26 of the 120 cases （21.7%）. The farthest distance of histological micrometastasis was 3.5 mm, 5.3 mm and 6.0 mm in 95%, 99% and 100% cases, respectively. Macroscopic tumor thrornbi or rnacrosatellites were observed in 18 of 76 cases, and 149 rnicrometastases were found in the surrounding live in 25 （43.1%） of 58 cases with no macroscopic tumor thrombi. The farthest distance of histological micrometastasis was 4.5 mm, 5.5 mm and 6.0 mm in 95%, 99% and 100% cases, respectively. Two hundred and sixty-seven rnicrometastases were found in surrounding liver in 14 （77.8%） out of 18 cases with macroscopic tumor thrombi or macrosatellites. The farthest distance of histological micrometastasis was 18.5 mm, 18.5 mm and 19.0 mm in 95%, 99% and 100% cases, respectively. CONCLUSION： The required minimal length of RM is 5.5 mm and 6 mm respectively to achieve 99% and 100% rnicrometastasis clearance in surrounding liver of PLC patients without macroscopic tumor thrornbi or rnacrosatellites, and should be greater than 18.5 mm to obtain 99% rnicrometastasis clearance in surrounding liver of patients with macroscopic tumor thrornbi or rnacrosatellites.

Primary liver cancer in the elderly: report of 125 cases

OBJECTIVES: To understand the characteristics of primary, liver camcer (PLC) in the elderly and summarize the experience in treatment of such patients. METHODS: The clinical data of PLC in the elderly group (≥60 years, 125 patients) and the young group (≤59 years, 295 patients) were analyzed retrospectively. RESULTS: In the elderly group, 64 patients were found HBsAg positive, 39 patients small PLC, 24 large PLC, 15 tumor emboli in the portal vein, 86 AFP positive, and 34 hepatectomy performed. In the young group, 205 patients were found HBsAg positive, 79 patients small PLC, 97 large PLC, 96 tumor emboli in the portal vein, 200 AFP positive, and 126 hepatectomy performed. The median survival was 44 and 25 months respectively, and no significant difference was observed in the mortality between the two groups (P>0.05). CONCLUSIONS: Hepatectomy is a choice of treatment for PLC in the elderly based on their liver function. AFP and B-ultrasonography are important methods for the diagnosis of PLC in the elderly.

Prealbumin is predictive for postoperative liver insufficiency in patients undergoing liver resection

AIM:To investigate the risk factors for postoperative liver insufficiency in patients with Child-Pugh class A liver function undergoing liver resection.METHODS:A total of 427 consecutive patients undergoing partial hepatectomy from October 2007 to April 2011 at a single center(Department of Hepatic SurgeryⅠ,Eastern Hepatobiliary Surgery Hospital,Shanghai,China) were included in the study.All the patients had preoperative liver function of Child-Pugh class A and were diagnosed as having primary liver cancer by postoperative histopathology.Surgery was performed by the same team and hepatic resection was carried out by a clamp crushing method.A clamp/unclamp time of 15 min/5 min was adopted for hepatic inflow occlusion.Patients' records of demographic variables,intraoperative parameters,pathological findings and laboratory test results were reviewed.Postoperative liver insufficiency and failure were defined as prolonged hyperbilirubinemia unrelated to biliary obstruction or leak,clinically apparent ascites,prolonged coagulopathy requiring frozen fresh plasma,and/or hepatic encephalopathy.The incidence of postoperative liver insufficiency or liver failure was observed and the attributing risk factors were analyzed.A multivariate analysis was conducted to determine the independent predictive factors.RESULTS:Among the 427 patients,there were 362 males and 65 females,with a mean age of 51.1 ± 10.4 years.Most patients(86.4%) had a background of viral hepatitis and 234(54.8%) patients had liver cirrhosis.Indications for partial hepatectomy included hepatocellular carcinoma(391 patients),intrahepatic cholangiocarcinoma(31 patients) and a combination of both(5 patients).Hepatic resections of ≤ 3 and ≥ 4 liver segments were performed in 358(83.8%) and 69(16.2%) patients,respectively.Seventeen(4.0%) patients developed liver insufficiency after hepatectomy,of whom 10 patients manifested as prolonged hyperbilirubinemia unrelated to biliary obstruction or leak,6 patients had clinically apparent ascites and prolonged coagulopathy,1 patient had hepatic encephalopathy and died on day 21 after surgery.On univariate analysis,age ≥ 60 years and prealbumin < 170 mg/dL were found to be significantly correlated with postoperative liver insufficiency(P = 0.045 and P = 0.009,respectively).There was no statistical difference in postoperative liver insufficiency between patients with or without hepatitis,liver cirrhosis and esophagogastric varices.Intraoperative parameters(type of resection,inflow blood occlusion time,blood loss and blood transfusion) and laboratory test results were not associated with postoperative liver insufficiency either.Age ≥ 60 years and prealbumin < 170 mg/dL were selected on multivariate analysis,and only prealbumin < 170 mg/dL remained predictive(hazard ratio,3.192;95%CI:1.185-8.601,P = 0.022).CONCLUSION:Prealbumin serum level is a predictive factor for postoperative liver insufficiency in patients with liver function of Child-Pugh class A undergoing hepatectomy.Since prealbumin is a good marker of nutritional status,the improved nutritional status may decrease the incidence of liver insufficiency.

Preoperative immunonutrition in patients undergoing liver resection:A prospective randomized trial

BACKGROUND Preoperative supplementation with immunonutrients, including arginine and n-3 fatty acids, has been shown in a number of systematic reviews to reduce infectious complications in patients who have undergone gastrointestinal surgery. Limited information, however, is available on the benefits of nutritional supplementation enriched with arginine and n-3 fatty acids in patients undergoing liver resection.AIM To evaluate the effects of preoperative nutritional supplementation enriched with arginine and n-3 fatty acids on inflammatory and immunologic markers and clinical outcome in patients undergoing liver resection.METHODS Thirty-four patients undergoing liver resection were randomized to either five days of preoperative Impact? [1020 kcal/d, immunonutrition(IMN) group], or standard care [no supplementation, standard care(STD) group]. Nutritional status was measured at study entry by subjective global assessment(SGA).Functional assessments(grip strength, fatigue and performance status) were carried out at study entry, on the day prior to surgery, and on postoperative day(POD) 7 and 30. Inflammatory and immune markers were measured at study entry, on the day prior to surgery, and POD 1, 3, 5, 7, 10 and 30. Postoperative complications were recorded prospectively until POD30.RESULTS A total of 32 patients(17 IMN and 15 STD) were analysed. All except four patients were SGA class A. The plasma ratio of(eicosapentaenoic acid plus docosahexaenoic acid) to arachidonic acid was higher in IMN patients on the day prior to surgery and POD 1, 3, 5 and 7(P < 0.05). Plasma interleukin(IL)-6 concentrations were elevated in the IMN group(P = 0.017 for POD7). No treatment effect was detected for functional measures, immune response(white cell count and total lymphocytes) or markers of inflammation(C-reactive protein,tumour necrosis factor-α, IL-8, IL-10). There were 10 patients with infectious complications in the IMN group and 4 in the STD group(P = 0.087). Median hospital stay was 9(range 4–49) d in the IMN group and 8(3-34) d in the STD group(P = 0.476).CONCLUSION In well-nourished patients undergoing elective liver resection, this study failed to show any benefit of preoperative immunonutrition.

目的:对比分析3D腹腔镜下区域性入肝血流阻断法和间歇性全入肝血流阻断法在腹腔镜肝切除术(LH)治疗原发性肝癌(PLC)患者术后恢复情况。方法:选择109例(2023年3月至2024年3月)PLC患者进行研究,均接受LH手术治疗,将使用区域性入肝血流阻断法的54例患者作为研究的观察组,将使用间歇性全入肝血流阻断法的55例患者作为研究的对照组。对比分析围手术期指标,统计手术治疗之前、手术结束后3d的肝功能指标和胃肠功能指标变化情况。结果:观察组手术操作及治疗时间、手术期间出血情况、肝血流阻断时间和整体住院时间均低于对照组(P<0.05);观察组经3个月随访后,并发症发生率为3.70%,低于对照组的18.18%(P<0.05)。观察组经手术治疗结束后3d血清ALT、AST、TBIL、DBIL水平与术前相比的差值小于对照组(P<0.05);观察组经手术治疗结束后3d血清GAS含量、血浆MTL水平与术前相比的差值小于对照组(P<0.05)。结论:与PLC患者使用3D腹腔镜下区域性入肝血流阻断法治疗相比,间歇性全入肝血流阻断法手术时间短、术中出血量相对较少、无血流阻断时间,同时可缩短住院时间,这可能与该手术对术后肝功能和胃肠功能影响较小有关。
