Central hepatectomy versus major hepatectomy for patients with centrally located hepatocellular carcinoma: a systematic review and meta-analysis.

ABSTRACT:

Background and aim

For those with a centrally located HCC, the two types of liver sectionectomy that can be performed are extended hepatectomy (EH) and central hepatectomy (CH). This meta-analysis aimed to compare the short- and long-term outcomes between patients treated with CH and patients treated with EH for those with centrally located HCC.

Method

We searched PubMed, Scopus, Web of Science, and Cochrane library for eligible studies from inception to 1 April 2022 and a systematic review and meta-analysis were done to compare the outcomes between the two groups.

Results

we included 9 studies with a total of 1674 patients in this study. The pooled results in this meta-analysis showed equal long-term overall survival, Disease-free survival, recurrence and mortality between the two groups (5-year OS, RR = 1.14, 95% CI = 0.96-1.35, P = 0.12; I² = 56%), (5-year DFS, RR = 0.81, 95% CI = 0.61-1.08, P = 0.15; I² = 60%), (Recurrence, RR = 1.04, 95% CI = 0.94-1.15, P = 0.45; I² = 27%), and (Mortality, RR = 0.55, 95% CI = 0.26-1.15, P = 0.11; I² = 0%). In addition to that, no significant difference could be detected in the overall incidence of complications between the two groups (Complications, RR = 0.94, 95% CI = 0.76-1.16, P = 0.57; I² = 0%). However, CH is associated with a remarkable increase in the rate of biliary fistula (Biliary fistula, RR = 1.90, 95% CI = 1.07-3.40, P = 0.03; I² = 0%). And Liver cell failure was higher in the case of EH (LCF, RR = 0.47, 95% CI = 0.30-0.76, P = 0.002; I² = 0%). Regarding the operative details, CH is associated with longer operative time (Time of the operation, Mean difference = 0.82, 95% CI = 0.36, 1.27, P = 0.0004; I² = 57%).

Conclusion

No significant difference in the short and long-term survival and recurrence between CH and MH for CL-HCC. However, CH is associated with greater future remnant liver volume that decreases the incidence of LCF and provides more opportunities for a repeat hepatectomy after tumour recurrence.

Project description:BackgroundSeveral randomized controlled trials (RCTs) compared the effects of laparoscopic hepatectomy (LH) and radiofrequency ablation (RFA) for the treatment of hepatocellular carcinoma (HCC), but the results have remained inconsistent. Hence, a meta-analysis and a systematic review of these treatment modalities are necessary to evaluate their efficacy and safety for HCC treatment.MethodsFrom the inception of this meta-analysis and review until August 31, 2019, we searched Medline, PubMed, EMBASE, Cochrane Library, China National Knowledge Infrastructure, Wanfang Database, and China Biomedical Literature Database for RCTs involving LH and RFA treatments of patients with HCC. The studies were screened and the data from these articles were extracted independently by two authors. Summary odd ratios (OR) or mean differences (MD) with 95% confidence intervals (CI) were calculated for each outcome with a fixed- or random-effect model. The outcomes for effectiveness evaluations included duration of surgery, estimated bleeding volume, incidence of blood transfusion during surgery, duration of hospital stay, and the outcome for safety included the incidence of cancer recurrence.ResultsSeven RCTs with a total of 615 patients were identified, 312 and 303 of which underwent RFA and LH treatments, respectively. The duration of surgery (MD = -99.04; 95% CI: -131.26--66.82), estimated bleeding volume (MD = -241.97; 95% CI: -386.93--97.02), incidence of blood transfusion during surgery (OR = 0.08; 95% CI: 0.02-0.37), and duration of hospital stay (MD = -3.4; 95% CI: -5.22--1.57) in RFA treatment were significantly lower than those of LH treatment. However, the incidence of cancer recurrence was significantly higher for RFA treatment compared with LH treatment (OR = 2.68; 95% CI: 1.72-4.18).ConclusionsLH treatment is preferred over RFA treatment with a better radical effect, but RFA treatment is more beneficial with smaller trauma, development of less complications, and shorter operating time when compared with HCC treatment.

Project description:BackgroundLimited anatomical liver resection for hepatocellular carcinoma (HCC) is complicated in cirrhotic patients with centrally located HCC and limited liver reserve. We present a case of total laparoscopic left medial and right ventroanterior sectionectomy performed using the intrahepatic Glissonian approach in a cirrhotic liver for curative resection of HCC.MethodsThe patient was a 69-year-old man with a 6.5-cm-diameter HCC located at segments 4, 5, and 8 and which was compressing the middle hepatic vein (MHV). Child-Pugh class A liver cirrhosis was noted, and the 15-min retention rate for indocyanine green was 14 %. Preoperative surgical planning suggested the feasibility of limited anatomical subsegmental resection. The patient was placed in the supine position and 5 trocars were used for the procedure. The operation began with cholecystectomy, division of liver ligaments, and exposure of the right hepatic vein root and the umbilical Glissonian pedicles to the left medial segment. Parenchymal transection was performed using a laparoscopic harmonic scalpel and Cavitron Ultrasonic Surgical Aspirator until the MHV was reached. After exposing the ventral branches of the right anterior Glissonian pedicle and dividing them, resection was continued along the demarcation line. Fissure veins draining to the MHV root were identified and divided. The MHV root was closed using an automatic stapler.ResultsThe operation time was 565 min and estimated blood loss was 665 ml; blood transfusion was not required. Pathological examination confirmed a moderately differentiated HCC with all resected margins free of malignancy. Postoperative recovery was uneventful and the patient was discharged on the postoperative day 7. There was no tumor recurrence 18 months after the operation.ConclusionsTotal laparoscopic left medial and right ventroanterior sectionectomy via the intrahepatic Glissonian approach is feasible for HCC in a cirrhotic liver with limited liver reserve. Preoperative planning is essential in order to compute successful hepatic function. Standardization of surgical techniques may aid in safely performing this procedure.

Project description:BackgroundSpontaneous rupture is a life-threatening complication of hepatocellular carcinoma (HCC). Recent trends in surgical treatments avoid emergency hepatectomy (EH) and favor emergency transarterial embolization (TAE) followed by delayed hepatectomy (DH). Still, there is debate on which is the better treatment option and whether delaying hepatectomy increases peritoneal metastasis.AimTo provide evidence-based references for the optimal management of patients with spontaneously ruptured HCC by comparing the outcomes of EH and DH.MethodsLiterature on postoperative outcomes of EH and DH in patients with spontaneously ruptured HCC published between the date of the database establishment and May 2022, was identified in the PubMed, EMBASE, and Cochrane Library databases. Revman 5.3 software was used for statistical analyses.ResultsNine publications were identified, including a total of 681 patients. Of those, 304 underwent EH, and 377 underwent TAE followed by DH. The meta-analysis results indicated that the in-hospital mortality rate in the EH patient group was significantly higher than that in the DH patient group (relative risk (RR) = 2.17, 95% confidence interval (CI) 1.03-4.57, p =0.04). There was no significant differences in the rates of postoperative complications (RR = 1.21, 95% CI 0.77-1.90, p = 0.40), postoperative hospital stay (WMD = - 0.64, 95% CI - 5.61-4.34, p = 0.80), recurrence (RR = 1.09, 95% CI 0.94-1.25, p = 0.27), peritoneal metastasis (RR = 1.06, 95% CI 0.66-1.71, p = 0.80), 1-year survival (RR = 0.91, 95% CI 0.80-1.02, p = 0.11), or 3-year survival (RR = 0.81, 95% CI 0.61-1.09, p = 0.17) in survivors between the two patient groups.ConclusionThe postoperative outcomes of the spontaneously ruptured HCC survivors who received EH were similar to those who received emergency TAE followed by DH. However, the in-hospital mortality rate was higher in EH patients. Based on the findings, DH with TAE first strategy might be considered over EH as the first line treatment modality. However, these findings await further validation by future high-quality studies.
