ObjectiveTo investigate the impact of elevated fasting blood glucose (FBG) level after open radical hepatectomy on the early recurrence of hepatocellular carcinoma (HCC).MethodsThe clinical data of 112 patients with HCC who underwent the open radical hepatecomy from January 2013 to December 2014 in the Affiliated Hospital of Qingdao University were retrospectively analyzed. After the radical resection of HCC, 86 patients with level of FBG 3.9–6.1 mmol/L and 26 patients with level of FBG≥6.1 mmol/L were design into a normal FBG group and an elevated FBG group, respectively. The recurrence rates of HCC were compared between the two groups at 1- and 2-year after the opreation.ResultsThere were no significant differences between the 2 groups in the gender, age, history of alcohol drinking, hepatitis B history, preoperative ALT, AST, AFP and Child-Pugh classification, scope of hepatectomy, intraoperative hemorrhage, hepatic blood flow occlusion, diameter of maximal tumor, histopathological differentiation, tumor number, cirrhosis, satellite lesion, postoperative adjuvant TACE treatment or not (P>0.05). The postoperative 1- and 2-year recurrence rates of HCC were 19.8% (17/86) and 33.7% (29/86) in the normal FBG group and 42.3% (11/26) and 61.5% (16/26) in the elevated FBG group, respectively, showing significant differences between the 2 groups (P<0.05). The results of multivariate analysis showed that the level of FBG≥6.1 mmol/L, low histopathological differentiation, and no postoperative TACE treatment were the independent risk factors affecting tumor-free survival rate after the open radical resection of HCC (P<0.05). ConclusionsElevated FBG level after open radical resection has a stimulative effect on early recurrence of HCC. As a result, monitoring and controlling of FBG level after operation is helpful in decreasing early recurrence rate of patients with HCC.
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.
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.
ObjectiveTo explore the risk factors for failure of enhanced recovery after surgery (ERAS) in partial hepatectomy. MethodsA retrospective analysis was performed on 344 patients who underwent partial hepatectomy at the Division of Liver Surgery, Department of General Surgery in West China Hospital of Sichuan University from January 2019 to December 2019. All patients were treated with ERAS after partial hepatectomy. Univariate and multivariate logistic regression analysis were used to evaluate the risk factors associated with failure of the ERAS after partial hepatectomy. ResultsA total of 344 patients were included in the study, including 44 patients in the ERAS failure group and 300 patients in the ERAS success group. Multivariate logistic regression showed that combined with chronic diseases [OR=2.32, 95%CI (1.07, 4.93), P=0.03] and intraoperative fluid replacement volume ≤2 475 mL [OR=2.16, 95%CI (1.06, 4.42), P=0.03] were risk factors for failure of ERAS. ConclusionChronic diseases and intraoperative fluid volume ≤2 475 mL are risk factors for the failure of ERAS after partial hepatectomy and can affect prognosis.
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.
Objective To assess the value of precise hepatectomy in treatment of primary hepatocellular carcinoma. Methods Three-dimensional (3D) models from MR image were reconstructed by 3D-Doctor software in 32 patients with primary hepatocellular carcinoma scheduled for liver resection between July 2007 and Sept 2009. From these 3D models, the vena cava, portal vein, hepatic vein, and short hepatic vein images were reconstructed, total liver volume, tumor volume, functional liver volume and ratio of functional liver volume to standard liver volume (SFLVR) were calculated. The patients were followed-up for 1-27 months, with an average of 12 months. Results The anatomic detail of liver veins and its relationship with the tumor could be displayed clearly in liver 3D models. By the 3D models, total liver volume was calculated as （1 353±419）ml, tumor volume as （287±248） ml, functional liver volume as （830±289） ml, and SFLVR as （71±22）%. Of 32 patients with hepatocellular carcinoma, right hemihepatectomy was performed in 8 cases, left hemihepatectomy in 2, and segmental or limited resection in 22. All operations were completed successfully. Postoperative complications included pulmonary infection in 1 case, bile leak in 1, moderate ascites (500-3 000 ml) in 8, and massive ascites (gt;3 000 ml) in 2 including one patient developed hepatic failure. Six and 12-month survival rates were 100% and 87%. Three, 6, and 12-month disease-free survival rates were 78%, 72%, and 72%. Conclusions Precise hepatectomy technique provides an accurate picture of liver veins anatomy and its relationship with the tumor， and allows the procedure to be simulated preoperatively for adequate and safe hepatectomy.
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 summarize clinical applications of inferior right hepatic vein (IRHV) in liver surgery and to provide a basis for clinical applications of IRHV.MethodThe relevant literatures about clinical applications of IRHV in liver surgery in recent years were reviewed.ResultsAs a kind of short hepatic veins, the IRHV directly flowed into the inferior vena cava, often accompanied by the portal vein of the segment Ⅵ. The occurrence rate of IRHV was 80%–90% by the autopsy examination, while which was 10%–30% by the imaging examination. The caliber of IRHV was 0.22–0.95 cm, and its caliber was negatively correlated with the caliber of right hepatic vein. The IRHV played a great role in the classification and treatment of the Budd-Chiari syndrome. According to the Couinaud liver classification method, the IRHV mainly drained the blood of segment Ⅵ. The existence of IRHV expanded the indications of hepatectomy. The reconstruction of IRHV in the liver transplantation could not only reserve the function of donor liver, but could compensatively drain the corresponding liver areas if the acute occlusion of other major hepatic veins happened.ConclusionsIRHV has some important clinical significances in liver surgery. Fully studying course characters and adjacent relationship of IRHV can not only avoid injury during surgery, but also provide a new treatment idea for related liver diseases.
ObjectiveTo explore the safety and feasibility of mixed approach laparoscopic anatomical left hepatectomy for left hepatolithiasis.MethodThe clinical data and follow-up results of 23 patients with left hepatolithiasis admitted to the Department of Hepatobiliary Pancreatic Surgery in Leshan People’s Hospital from June 2018 to June 2020 were retrospectively analyzed.ResultsAll 23 patients underwent anatomical left hepatectomy under laparoscopy. The median of total operation time was 185 min (153–460 min), the median of operation time of liver dissection was 110 min (90–125 min), the median of total blood loss during operation was 175 mL (100–800 mL), the median of blood loss from liver dissection was 120 mL (60–560 mL), blood transfusion was performed in 2 patients during operation. Postoperative day 1: median of AST was 75 U/L (32–437 U/L), median of ALT was 83 U/L (25–537 U/L),median of TBIL was 24 μmol/L (15.6–42.7 μmol/L); postoperative day 3: median of AST was 31 U/L (23–129 U/L),median of ALT was 27 U/L (14–108 U/L), median of TBIL was 13.5 μmol/L (10.4–24.3 μmol/L). Postoperative blood transfusion was performed in 1 patient, and the median of postoperative hospital stay was 7 days (5–20 days), median of postoperative extubation time was 2.5 days (2–5 days). Postoperative complications occurred in 3 patients. All 23 patients were followed up after the operation for median of 12 months (6–18 months). During the follow-up period, the patients had no special discomfort, no stone recurrence, reoperation, and death.ConclusionMixed approach laparoscopic anatomical left hepatectomy is safe and feasible in the treatment of left hepatolithiasis.
ObjectiveTo evaluate the effects of indocyanine green (ICG) fluorescence imaging in laparoscopic anatomic hepatectomy. MethodsThe clinical data of 26 patients who underwent ICG fluorescence-guided laparoscopic anatomic hepatectomy in the Department of Hepatobiliary Surgery at Affiliated Hospital of North Sichuan Medical College from March 2019 to May 2023 were retrospectively analyzed. ICG staining methods included combined lipiodol-ICG (SHIFT&nanoICG) hepatic artery embolization (anterograde staining) and (or) portal vein retrograde staining. Patient demographics, pathological characteristics, intraoperative outcomes (ICG staining method and results, operation time, intraoperative blood loss, transfusion rate, conversion to open surgery), and postoperative outcomes [alanine aminotransferase (ALT), aspartate aminotransferase (AST), albumin (ALB), total bilirubin (TB) levels on postoperative day 3, hospital stay, complications] were analyzed. Quantitative data conforming to a normal distribution were described as mean ± standard deviation, while skewed distributions were described as median (interquartile range). The significance level was set at α=0.05. ResultsAmong 26 patients, 6 received combined anterograde (SHIFT&nanoICG) + retrograde staining (referred to as the “dual-staining group”), while 20 received retrograde staining alone (referred to as the “single-staining group”). One case (3.8%) in the single-staining group required conversion to open surgery. All resection margins were negative. No statistically significant differences were observed between the dual-staining group and the single-staining group for the following parameters: Tumor diameter [5.0 (4.4) cm vs. 4.0 (4.2) cm, P=0.483], operative time [307.0 (146.0) min vs. 250.0 (137.5) min, P=0.831], intraoperative blood loss [250.0 (225.0) mL vs. 225.0 (338.0) mL, P=0.756], postoperative hospital stay [(12.3±2.1) d vs. (10.9±2.7) d, P=0.232]. Furthermore, no significant differences were found in ALT, AST, ALB, and TB levels on postoperative day 3 (P>0.05). Regarding postoperative complications (classified according to the Clavien-Dindo system): One patient with grade Ⅰ complication was recorded in the dual-staining group, 3 with grade Ⅰ and 3 with grade Ⅱ complications were recorded in the single-staining group, no grade Ⅲ or higher complications occurred in either group. Comparison of complication rate between the two groups showed no statistically significant difference (P=0.600). ConclusionsBoth conventional ICG and SHIFT&nanoICG provide effective fluorescence guidance for laparoscopic anatomic hepatectomy. For patients with hepatocellular carcinoma who are ineligible for primary radical resection or have lost the opportunity for initial curative surgery, SHIFT&nanoICG provides superior intraoperative fluorescence visualization following transarterial embolization-assisted conversion therapy.
