ObjectiveTo explore the combined application of neutrophil to lymphocyte ratio (NLR) and systemic immune inflammation index (SII) on the prognosis of hepatitis B-related hepatocellular carcinoma after resection.MethodsRetrospectively collected data of 180 patients with hepatitis B-related hepatocellular carcinoma who were hospitalized in the Department of Infectious Diseases and Hepatobiliary Surgery of the Affiliated Hospital of Southwest Medical University and received surgical treatment from January 2013 to December 2019, including general information, laboratory examination and abdominal CT or MRI results. NLR and SII values were measured at one week before operation, and their critical values of NLR and SII were determined by ROC curve analysis. Univariate and multivariate analysis were performed to determine the risk factors to predict the survival status of patients with hepatitis B-related hepatocellular carcinoma after hepatectomy.ResultsUnivariate analysis showed that AFP, platelets, TNM staging, portal vein tumor thrombus, tumor differentiation, NLR, SII, and NLR+SII combined score were significantly correlated with the prognosis of patients with hepatitis B-related hepatocellular carcinoma (P<0.05). Multivariate analysis showed that PLT [HR=1.791, 95%CI (1.124, 2.854), P=0.014], NLR [HR=4.289, 95%CI (2.571, 7.156), P<0.001], SII [HR=5.317, 95%CI (3.016, 9.374), P<0.001], and NLR+SII combined score [HR=7.901, 95%CI (4.124, 15.138), P<0.001] were independently correlated with the survival of patients with hepatitis B-related hepatocellular carcinoma.ConclusionsThe preoperative NLR+SII combined score can be used to evaluate the postoperative prognosis of patients with hepatitis B-related hepatocellular carcinoma. The higher the score, the lower the postoperative survival rate.
ObjectiveTo introduce the basic principles of commonly used assessment methods for liver function reserve, and compare the advantages and disadvantages of various assessment methods, so as to provide a reference for hepatectomy of patients with hepatocellular carcinoma (HCC). MethodThe literature on evaluation methods of liver reserve function in patients with HCC at home and abroad in recent years was searched and summarized. ResultsFrom the results of literature review, the Child‐Pugh score and indocyanine green discharge test were the most commonly used to assess preoperative liver function reserve for patients with HCC. The application value of other examinations such as albumin-bilirubin score, gadolinium-ethoxybenzyl diethylenetriamine pentaacetic acid-enhanced magnetic resonance imaging (Gd-EOB-DTPA-enhanced MRI), nuclear medical imaging in predicting post-hepatectomy liver failure was gradually being explored. ConclusionsThe combination of clinical parameters and volumetric studies is used to assess preoperative liver function reserve for patients with HCC. The clinical applications of nuclear medical imaging and Gd-EOB-DTPA-enhanced MRI make up for the deficiency of local liver function reserve evaluation, which are important examinations to assess liver function reserve after conversion therapy in the future. However, more domestic studies are still needed to confirm their values.
ObjectiveTo investigate the clinical application of laparoscopic right hemihepatectomy via anterior approach. MethodThe clinical data of 32 patients underwent laparoscopic right hemihepatectomy via anterior approach from June 2017 to May 2019 were retrospectively analyzed.ResultsThe laparoscopic right hemihepatectomies via anterior approach were successfully completed in the 32 patients, no one converted to laparotomy. The operation time was (315.5±36.7) min, the intraoperative bleeding was (340.8±105.4) mL, and the postoperative hospital stay was (8.9±1.7) d. The postoperative complications occurred in 6 cases, including 1 case of peritoneal effusion, 1 case of intraabdominal infection, 2 cases of bile leakage and 2 cases of pleural effusion combined with pulmonary infection, who were discharged after receiving the conservative treatment according to the symptoms. The results of postoperative pathology: 13 cases of hepatocellular carcinoma, 6 cases of intrahepatic cholangiocarcinoma, 7 cases of hepatic angioleiomyoma, 6 cases of intrahepatic bile duct stones. The average follow-up time was 12 months (range 1 to 24 months). During the follow-up period, 7 cases of hepatic angioleiomyoma and 6 cases of hepatolithiasis survived after operation. The intrahepatic metastases were found in 1 patient with hepatocellular carcinoma at 12 months and 2 cases of intrahepatic cholangiocarcinoma at 9 months and 11 months, respectively. The rest patients survived free tumor.ConclusionLaparoscopic right hemihepatectomy via anterior approach is safe and feasible, and has a satisfactory short-term efficacy.
ObjectiveTo investigate the value of laparoscopic liver venous deprivation (LLVD) in promoting the growth of contralateral future liver remnant (FLR) during two-step hepatectomy. MethodThe clinicopathologic data of a 45-year-old female patient with pancreatic neuroendocrine tumor with multiple liver metastases (grade G2) treated by two-step hepatectomy based on LLVD in January 2022 in the Sichuan Provincial People’s Hospital were analyzed retrospectively. ResultsThe liver function returned to normal within 10 d after LLVD, and the relative increase ratio of FLR reached to 98.35% on postoperative day 10. The laparoscopic right hemi-hepatectomy and distal pancreatectomy plus splenectomy was performed without any postoperative complications, and the patient was discharged from hospital on postoperative day 8. No tumor recurrence or metastasis occurred during the follow-up period. ConclusionsFrom the analysis results of this case, the LLVD could promote the growth of FLR safely and effectively. LLVD provides an alternative surgical method of two-step hepatectomy for treatment of benign and malignant liver tumors.
Objective To investigate the feasibility of elective laparoscopic hepatectomy in the treatment of ruptured hepatocellular carcinoma. Methods We tried to perform an elective laparoscopic hepatectomy for a middle-aged man who had a ruptured hepatocellular carcinoma without active hemorrhage. The data of this patient was summarized. Results The patient received the elective laparoscopic hepatectomy, and the liver lesions were completely removed. The operation was successful. Operative time was 300 min and intraoperative bleeding was 500 mL. Postoperative recovery of this patient was good and no complication occurred. The abdominal drainage tube was removed on 4 days after operation, and he discharged on 8 days after operation. The pathology confirmed that the hepatocellular carcinoma was moderately differentiated and ruptured. Conclusion Elective laparoscopic hepatectomy is safe and feasible in the treatment of ruptured hepatocellular carcinoma for specific patient, but this operation needs to be performed by experienced surgeons with laparoscopic skills.
ObjectiveTo investigate the role of endoplasmic reticulum stress in liver regeneration after associating liver partition and portal vein ligation for staged hepatectomy (ALPPS).MethodsSeventy-two C57bl/6 mice were randomly divided into ALPPS group, portal vein ligation group (PVL group), and sham operation group (Sham group), 24 mice in each group. And then one-stage ALPPS operation, simple PVL, and sham operation will be performed. Six mice were randomized selected of the three groups on the 1st, 2nd, 4th, and 7th day after surgery, respectively, the liver weight to body weight ratio (FLR/BW) of each group was measured, and the liver tissues were taken for immunohistochemical staining to calculate the proportion of Ki-67 positive cells, Western blot was used to detect the expression levels of X-box binding protein 1 (XBP1) and inositol-requiring enzyme 1α (IRE1α) proteins.Results① FLR/BW: On the 4th day and the 7th day after operation, the FLR/BW of the Sham group, PVL group, and ALPPS group increased in sequence at the same time, and the difference between the three groups was statistically significant (P<0.05). ② Ki-67 positive cell ratio: On the 2nd day after operation, the ratio of Ki-67 positive cells in the Sham group, PVL group, and ALPPS group increased sequentially, and the difference between the two groups was statistically significant (P<0.05). On the 4th day after operation, the ratio of Ki-67 positive cells in the PVL group and the ALPPS group were still higher than that of the Sham group (P<0.05). ③ Expression levels of XBP1 and IRE1α: On the 2nd and 4th postoperative day, the expression levels of XBP1 and IRE1α in the ALPPS group were higher than those in the Sham group and the PVL group (P<0.05). On the 7th day after surgery, the expression levels of XBP1 and IRE1α in the ALPPS group were higher than those in the Sham group (P<0.05), while compared with the PVL group, the expression level of XBP1 in the ALPPS group was still higher (P<0.05).ConclusionsALPPS-induced liver regeneration is more advantageous than traditional PVL in mice. It may be attributed to the obvious endoplasmic reticulum stress activation after ALPPS leading to the up-regulation of IRE1α-XBP1 expression, which is involved in the regulation of hepatocyte cell cycle and promotes hepatocyte proliferation, thus promoting rapid liver regeneration.
ObjectiveTo explore the clinical application of variant associating liver partition and portal vein ligation for staged hepatectomy (ALPPS) combined with inferior vena cava reconstruction for end stage hepatic alveolar echinococcosis (HAE).MethodThe clinical data of one case with HAE who treated in Organ Transplantation Center of Sichuan Provincial People’s Hospital in November 2017 was analyzed retrospectively.ResultsComputed tomography revealed that the three hepatic veins and retrohepatic inferior vena cava were invaded by multiple and giant hydatid lesions. Only the segment 6 retained the complete portal vein and hepatic vein return branch. Remnant liver volume/standard liver volume (RLV/SLV) of this patient was 24.9%. Surgical exploration was performed after preoperative examination. In the first stage, ligation of the left portal vein and the right anterior lobe portal vein were performed to increase portal blood supply at S6 while partial split of the liver. The patient recovered well after operation without complications such as bile leakage and infection. Six months after the first stage surgery, the second stage surgery was performed, and RLV/SLV measured before surgery was 48.3%. S1–5/S7–8 were completely removed and the hepatic inferior vena cava was reconstructed with artificial blood vessels. The patient was discharged on 10 days after operation, and there was no complications and relapses occurred during the 18 months follow-up period.ConclusionsVariant ALPPS combined with inferior vena cava reconstruction is an effective attempt to treat end stage HAE with multiple and giant hydatid lesions and insufficient RLV.
ObjectiveTo evaluate the effectiveness and safety of associating liver partition and portal vein ligation for staged hepatectomy (ALPPS) combined with laparoscopic-assisted microwave ablation (Lap-MWA) for the liver resection in the treatment of unresectable primary hepatic carcinoma. Methods This study analyzed the clinical data of 12 hepatic carcinoma patients who underwent ALPPS combined with Lap-MWA for the liver resection from January 2019 to June 2021 in the Department of Hepato-Pancreato-Biliary Surgery of Qinzhou First People’s Hospital. The patients had insufficient future liver remnant (FLR) and different degrees of liver cirrhosis. The 1-stage ALPPS was to perform after the laparoscopic-assisted ligation of the portal vein of the loaded tumor. At the same time, the microwave ablation was used for the liver parenchyma segmentation under the guidance of laparoscopic ultrasound (LUS) without separating liver parenchyma. Other steps were the same as classic ALPPS. Results All the 12 patients successfully completed the operation. The 1-stage ALPPS lasted 90–130 min, (110.25±35.34) min; the blood loss was 80–140 mL, (100.37±42.24) mL. The interval between 2 stages was 12–16 d, (14.0±2.5) d. The FLR/standard liver volume (SLV) increased to (58.00±3.30) %. The 2-stage ALPPS lasted 120–180 min, (150±30) min; the blood loss was 300–1 200 mL, (453.50±107.70) mL; the hospital stay after 2 stages of ALPPS operations was 11–16 d, (14±2) d. Among all patients, 4 U of leukocyte suspension was transfused in 1 patient, and pleural ascites occurred in 3 patients. There were no serious complications such as liver failure and severe infection, and no death cases. The total hospital stay was 14–22 d, (17±3) d. After the 1-stage ALPPS, the total bilirubin, white blood cells, glutamic-pyruvic transaminase level increased (P＜0.05), and total bilirubin and white blood cells gradually returned to the normal level on the 5th day after 1-stage ALPPS. On the 1st day after finishing the 2-stage ALPPS, albumin and hemoglobin decreased, while white blood cells, total bilirubin, prothrombin time and glutamic-pyruvic transaminase increased in varying degrees (P<0.05). And on the 5th day after the 2-stage ALPPS, all indicators gradually returned to normal. All the patients were followed up for 6–30 months, (20±6) months. Two patients died of tumor recurrence and metastasis at 6.2 months and 13 months after the surgery, respectively. No recurrence was found in other patients, and their life quality was good. Conclusion Preliminary results of this study indicate that ALPPS combined with Lap-MWA is safe and effective for the treatment of unresectable primary hepatic carcinoma.
Objective To systematically evaluate the effectiveness and safety of laparoscopic hepatectomy (LH) versus open hepatectomy (OH) for hepatocellular carcinoma (HCC). Methods Databases including PubMed, EMbase, MEDLINE, SCI, CNKI, CBM, WanFang Data and The Cochrane Library (Issue 3, 2012) were searched to collect the randomized controlled trails (RCTs) and non-RCTs about LH versus OH for HCC. The retrieval time was from inception to August 2012. The studies were screened according to the inclusion and exclusion criteria, the data were extracted and the quality was evaluated by 2 reviewers independently. Then the meta-analysis was conducted using RevMan 5.1 software. Results A total of 13 non-RCTs involving 701 patients were included. The results of meta-analysis showed that: Compared with OH, LH had lesser amount of intraoperative bleeding (MD=?144.09, 95%CI ?194.25 to ?93.94, Plt;0.000 01), shorter hospital stay (MD=?5.48, 95%CI ?7.10 to ?3.85, Plt;0.000 01), and lower postoperative complications (OR=0.43, 95%CI 0.27 to 0.66, P=0.000 1). But there were no differences between the 2 groups in operation time (MD=?0.64, 95%CI ?22.95 to 21.68, P=0.96), perioperative death rate, 3-5 year survival rate, and tumor free survival rate. Conclusion LH is superior to OH in treating HCC for it is associated with smaller wound, lesser operative blood loss, shorter hospital stay, and lower postoperative complications. And it is similar as OH in operation time, perioperative death rate and 3-5 year survival rate. So LH is safe and feasible for treating HCC when its indications are strictly controlled. However, for the quantity and quality limitation of the included studies, this conclusion still requires to be further proved by performing large scale and high quality RCTs. It suggests that doctors should choose a best therapy for HCC patients according to an integrative disease assessment.
Objective To diagnose and treat a patient with obstructive jaundice and hepatic bile duct tumor by multi-disciplinary team (MDT) and to provide individualized treatment. Methods By MDT model, a patient with obstructive jaundice and hepatic bile duct tumor, who was ever misdiagnosed as hilar cholangiocarcinoma, was discussed. The diagnosis, perioperative period management, and operation scheme were carried out by the MDT. Results After discussion of MDT, the patient was diagnosed as " hepatocellular carcinoma with bile duct tumor thrombi”, not " hilar cholangiocarcinoma”. Although hepatocellular carcinoma with bile duct tumor thrombi was end-stage disease, radical treatment was still considered. A plan of treatment was carried out by the MDT. Firstly, the percutaneous transhepatic cholangial drainage was operated for the predicted reserved half liver to relieve biliary obstruction. Secondly, hemihepatectomy combined with bile duct resection was carried out by the surgery team. The patient had nice postoperative recovery and there was no tumor recurrence after 6-month follow-up after surgery up to now. Conclusions MDT model do not only reduce misdiagnose, but also can provide the best therapeutic regimen and individualized treatment for patient presented with obstructive jaundice and hepatic bile duct tumor.
