Objective To systematically review the efficacy and safety of laparoscopic hepatectomy (LH) and open hepatectomy (OH) for patients with hepatocellular carcinoma (HCC). Methods PubMed, EMbase, The Cochrane Library, CBM, WanFang Data, CNKI databases were electronically searched to collect the case-control studies about LH vs. OH for patients with HCC from inception to December, 2015. Two reviewers independently screened literature, extracted data and assessed the risk of bias of included studies, then meta-analysis was performed by using RevMan 5.3 software. Results A total of 28 studies involving 1 908 patients were included. The results of meta-analysis showed that: the LH group was superior to OH group on complications (OR=0.35, 95%CI 0.26 to 0.48, P<0.000 01), hospital stay (MD=–4.18, 95%CI (–5.08, –3.29),P<0.000 01), and five years overall survival rate (OR=1.65, 95%CI 1.23 to 2.19,P=0.000 7) and disease-free survival rate (OR=1.51, 95%CI 1.12 to 2.03, P=0.006). However, no significant differences were found in one year and three years overall survival rate, disease-free survival rate, and postoperative recurrence rate. Conclusion Current evidence shows that the LH is superior to OH for the treatment of HCC, and may be amenable to surgery because of its safety and longtime efficacy. Due to limited quality and quantity of the included studies, more high quality studies are needed to verify above conclusion.
Bile leakage is a common complication of hepatocellular carcinoma (HCC) after hepatectomy, which affects the prognosis and medical quality. It is emphasized that taking preventive measures according to the etiology and related risk factors could help to reduce the incidence of bile leakage, improve the quality and safety of HCC diagnosis and treatment, and achieve the main indicators of HCC quality control in the 2022 version of National Cancer Center. In this review, combined with the team of Peng’s leakage test technology research and clinical practice, brief talk about personal experience.
ObjectiveTo summarize the current status and progress of surgical treatment for postoperative recurrent hepatocellular carcinoma (HCC).MethodThe literatures about studies of surgical treatment of postoperative recurrent HCC were reviewed.ResultsThe surgical operation was an effective method for the treatment of recurrent HCC. The operation methods included re-hepatectomy and salvage liver transplantation. There was no uniform standard for the indication of re-hepatectomy, but the basic principles were the same. At present, the indication of salvage liver transplantation was mainly based on Milan criteria. For patients with recurrent HCC who met the operation indications, surgical operation could improve the long-term survival rate of patients and benefit the patients.ConclusionIt migh prolong the survival time and improve the long-term survival rate of patients with recurrent HCC when the appropriate patients and reasonable surgical methods are chosen according to the surgical indications, the tumor situation of initial hepatectomy, postoperative recurrence time, and other factors.
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 evaluate efficacy and safety of laparoscopic Glissonean pedicle transection anatomic hepatectomy using indocyanine green (ICG) fluorescence imaging.MethodThe retrospective analysis was made on the preoperative clinical data, surgical treatment and postoperative status of a patient with hepatocellular carcinoma who underwent the laparoscopic Glissonean pedicle transection anatomic hepatectomy using the ICG fluorescence imaging technology in the Department of Liver Surgery, West China Hospital of Sichuan University.ResultsAccording to the preoperative history, imaging and laboratory examinations, the diagnosis of hepatocellular carcinoma was considered. The intraoperative exploration revealed that there was only one tumor located in the segment Ⅳ and was superficial. The ICG fluorescence imaging was used to perform the Glissonean pedicle transection anatomic hepatectomy. The postoperative pathological diagnosis was consistent with hepatocellular carcinoma without serious complications. The patient recovered well. No recurrence was found in the follow-up period up to 6 months.ConclusionsLaparoscopic Glissonean pedicle transection anatomic hepatectomy using ICG fluorescence technology can be used as a safe and precise treatment to solve problems such as bleeding during operation, difficult determination of tumor boundary, and whether having residual tumor in surgical margin.
Surgery is the only effective treatment for congenital choledochal cysts, as it allows for the resection of the cysts, the complete relief of cholangitis, and the prevention of canceration of cysts. The key elements of surgery for central choledochal cysts involve the cysts resection, bile-intestinal anastomosis, and biliopancreatic diversion. The difficulty in operating on central choledochal cysts lies in the rational decision making and effective management of cysts in the hilar and pancreatic regions. Depending on the type of central choledochal cysts with different anatomical patterns, a reasonable and feasible individualized surgical management strategy can be established to effectively avoid adverse therapeutic consequences such as postoperative biliary leakage, cholangio-intestinal anastomotic stricture, residual choledochal cysts and its carcinogenesis.
ObjectiveTo explore the efficiency of two-stage hepatectomy applicated in complex alveolar echinococcosis. MethodThe clinical data of one case who suffered from complicated alveolar echinococcosis with multiple lesions and then treated with two-stage hepatectomy were analyzed retrospectively. ResultsPreoperative enhanced CT revealed that the hydatid lesion with irregular shape, measuring 14.1 cm×9.2 cm, invaded several segments including left medial lobe and right anterior lobe of liver and the right branch of portal vein and medium hepatic vein were entirely surrounded by it. After preoperative examination surgical exploration was performed, two larger lesions measuring 6 cm×5 cm×4 cm and 5 cm×4 cm×4 cm respectively were found in caudate lobe of liver, three smaller lesions were found in the right and left lobe of liver, among which two measured 2 cm×2 cm×1 cm in the right lobe and one measured 3 cm×2 cm×1 cm in the left lobe. Mesohepatectomy was performed in the first stage, the lesion in left medial lobe and right anterior lobe of liver and the right anterior branch of portal vein were resected during the procedure. The patient recovered well after the operation without complications such as bile leakage or hemorrhage observed. The second stage surgery was performed at three months after operation, the computed tomograph before the surgery revealed that the remained lesions in the right lobe of liver did not proceed obviously and the left lateral external lobe of liver regenerated significantly. In the second stage, the right anterior lobe and part of the right posterior lobe of liver were resected. The patient was discharged on 7 days after operation, and there was no complication and relapse during the 7 months of follow-up period. ConclusionTwo-stage hepatectomy applicated in treating complicated alveolar echinococcosis with multiple lesions is safe and feasible, offering a choice with smaller trauma, lower expense and less complications for patients compared with liver transplantation.
ObjectiveTo explore the clinical application of in vivo hepatectomy with preservation of retrohepatic inferior vena cava (IVC) for hepatic alveolar echinococcosis (HAE) with the invasion of IVC. MethodsThe clinicopathologic data of a complicated HAE patient with large lesion (maximum cross-section 12.6 cm×9.6 cm), infiltrative growth, unclear boundary with surrounding tissues, and invasions of diaphragm and IVC (invasion length up to 4.6 cm) admitted to the Department of Liver Surgery in the West China Hospital of Sichuan University in December 2021 was retrospectively collected. The three-dimensional reconstruction of the liver model was performed by Mimics Medical 21.0 software before operation. The invading IVC of the right liver lesion was measured and the resection was simulated. During the operation, the HAE lesion and the affected IVC were gradually separated from IVC by the hemostatic forceps, and the residual lesions were gradually removed. ResultsIn this patient, the HAE lesion of right liver was resected, the IVC was entirely preserved, and the resection of liver was consistent with the preoperative three-dimensional reconstruction plan. The operation time was 275 min, the bleeding was approximately 500 mL. On the first day after the operation, the alanine aminotransferase and aspartate aminotransferase were increased, no obvious abnormalities were observed in the plasma albumin and bilirubin, the patient recovered and was discharged on the seventh day after the operation. No complications occurred after the operation, and no recurrence or metastasis of HAE was observed during follow-up period. ConclusionsHepatectomy with preservation of retrohepatic IVC for HAE with invasion of IVC is safe and effective. Taking albendazole regularly after surgery will help maintain disease-free survival.
Objective To systematically evaluate safety and effectiveness of using fast track surgery (FTS) protocol in perioperative management of hepatectomy. Methods The studies were collected by searching the PubMed, Web of Science, Cochrane Library, CNKI, Wanfang Data, and VIP databases by two researchers. The FTS management was used in the FTS group and the traditional perioperative management was used in the traditional group. The meta analysis was performed using the RevMan 5.3 software. Results A total of 28 articles were included in the study, of which 1 632 patients in the FTS group and 1 820 patients in the traditional group; 14 RCTs, 14 CCTs. The results of meta analysis showed: Compared with the traditional group, the FTS not only could reduce the pain of patients during 24 and 48 hours after the surgery [24 h: WMD=–0. 92, 95%CI (–1.05, –0.79), P<0.000 01; 48 h:WMD=–0.73, 95%CI (–0.90, –0.56), P<0.000 01], but also shorten the first postoperative flatus time of patients [WMD=–17.36, 95%CI (–23.16, –11.56), P<0.000 01] and the length of hospital stay [WMD=–2.42, 95%CI (–3.02, –1.63), P<0.000 01] and reduce the hos-pitalization expenses [WMD=–0.52, 95%CI (–0.64, –0.41, P<0.000 01]; While the incidences of pulmonary comp-lications [OR=0.51, 95%CI (0.32, 0.81), P=0.005], total complications [OR=0.57, 95%CI (0.38, 0.87), P=0.008], and nausea and vomiting [OR=0.45, 95%CI (0.31, 0.65), P<0.000 1] were significantly decreased. The RCT group and CCT group showed the same conclusions with the overall study (except incidence of postoperative pulmonary complications between the two groups in the CCT study). Conclusion For patients with elective hepatectomy, it seems feasible to use FTS protocol, which could promote postoperative bowel recovery, shorten length of hospital day, and save medical resources.
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.
