Objective: This multicenter study aimed to compare the short- and long-term outcomes of laparoscopic (LRLR) versus open repeat liver resection (ORLR) for recurrent hepatocellular carcinoma (HCC) using propensity score matching (PSM). Despite the expanding indications for laparoscopic liver resection, limited data regarding the outcomes of LRLR have previously been reported., Methods: This study included patients who underwent repeat liver resection for recurrent HCC. Patients were divided into the LRLR and ORLR groups, and their short- and long-term outcomes were compared via PSM., Results: There were 256 and 130 patients in the ORLR and LRLR groups, respectively. After PSM, 64 patients were included in each group. Intraoperative blood loss was significantly less in LRLR than in ORLR (56 vs 208 ml, P < .001). Postoperative complications of Clavien-Dindo IIIa or more were significantly less in LRLR than in ORLR (3.1% vs 15.6%, P = .030). The length of hospital stay was notably shorter in LRLR than in ORLR (9 vs 12 days, P < .001). Survival rates after repeat liver resection at 1, 3, and 5 years, respectively, were comparable at 93.4%, 81.9%, and 63.5% for ORLR and at 94.8%, 80.7%, and 67.3% for LRLR (P = .623). Subgroup analysis of patients who underwent wedge resection in repeat liver resection revealed that the postoperative complication rate was notably lower in LRLR than in ORLR (7.2% vs 21.8%, P = .030)., Conclusion: LRLR for recurrent HCC is a viable option due to its better short-term outcomes and comparable long-term outcomes compared to ORLR., (© 2022 Japanese Society of Hepato-Biliary-Pancreatic Surgery.)

Background: This study aimed to determine the risk factors for severe postoperative complications in patients undergoing pure laparoscopic liver resection (LLR) for tumors in the right posterosuperior (PS) segments., Methods: The study included 289 patients who underwent parenchyma-sparing pure LLR for tumors in the right PS segments at eight treatment centers between January 2009 and December 2019., Results: Multivariate analysis revealed tumor size ≥3 cm (P = .016), segmentectomy (P = .044), and liver cirrhosis (P = .029) as independent risk factors for severe postoperative complications. The severe complication rates (2.7% vs 12.1%, P = .0025), median intraoperative blood loss (100 mL vs 150 mL, P = .001), and median operation time (248 minutes vs 299.5 minutes, P = .0013) were lower in the patients without all these three risk factors than those with at least one risk factor. The median length of postoperative hospital stay was shorter in patients with no risk factors than those with at least one risk factor (9 days vs. 10 days, P = .001)., Conclusions: Tumor size ≥3 cm, segmentectomy, and liver cirrhosis were the risk factors for severe postoperative complications after parenchyma-sparing pure LLR for tumors in the right PS segments. Patients without these three risk factors would be appropriate candidates for safely performing parenchyma-sparing pure LLR in the right PS segments at the outset., (© 2022 Asia Endosurgery Task Force and Japan Society of Endoscopic Surgery and John Wiley & Sons Australia, Ltd.)

Background: We aimed to investigate whether a novel biomarker incorporating albumin, lymphocytes, and CRP can predict the prognosis for hepatocellular carcinoma (HCC) after hepatectomy., Methods: Between January 2011 and December 2013, 384 patients who underwent hepatectomy in four university hospitals in Japan were investigated as a discovery cohort. The CRP-Albumin-Lymphocyte (CALLY index) was defined as (Albumin × Lymphocyte)/(CRP × 10 4 ). Patients with a CALLY index ≥5 (n = 200) were compared to those with an index <5 (n = 184). Next, validation was performed using 267 patients from three other university hospitals (external validation cohort)., Results: The number of TNM Stage III and IV patients was significantly higher in the CALLY <5 group than the ≥5 group (p = 0.003). There was a significant difference in the 5-year survival rate (CALLY ≥5: 71% vs. <5: 46%; p < 0.001). Multivariate analysis identified the CALLY index as an independent factor of overall survival. Similarly, there was a significant difference in the 5-year survival rate between the CALLY ≥5 (73%) and <5 (48%) groups (p < 0.001), and the CALLY index was identified as an independent prognostic factor in the external validation cohort., Conclusion: The CALLY index derived from CRP, albumin, and lymphocyte values is a promising predictive biomarker for postoperative prognosis of patients with HCC., (Copyright © 2021 International Hepato-Pancreato-Biliary Association Inc.

Background: Hepatic resection (HR) is not recommended for intermediate-stage hepatocellular carcinoma (HCC) by the Barcelona Clinic Liver Cancer criteria. We examined the prognostic factors of HR for intermediate-stage HCC and developed new HR criteria for intermediate-stage HCC., Methods: A total of 110 patients who underwent HR without any prior treatment for intermediate-stage HCC between January 2007 and December 2012 were enrolled at eight university hospitals. The outcomes and prognostic factors of HR were evaluated to develop new HR criteria., Results: In terms of tumor size and number, the most significant prognostic factors were within the up-to-seven criteria. Furthermore, serum albumin level ≥35 g/L and serum alpha-fetoprotein (AFP) level.

Background: The frequency of liver resection in elderly patients has been increasing. However, data are limited regarding the safety of laparoscopic liver resection (LLR) compared with that of open liver resection (OLR) for hepatocellular carcinoma (HCC) in elderly patients. The present study aimed to compare short-term outcomes between LLR and OLR in elderly patients with HCC using propensity score matching., Methods: The study included 630 patients (age, ≥ 75 years) who underwent liver resection for HCC at nine liver centres between April 2010 and December 2017. Patients were divided into LLR and OLR groups, and perioperative outcomes were compared between the groups. In addition, subgroup analysis was performed according to age (75-79 and ≥ 80 years)., Results: Of the 630 patients, 221 and 409 were included in the LLR and OLR groups, respectively. After propensity score matching, 155 patients were included in each group. Intraoperative blood loss and the transfusion, post-operative overall complication and major complication rates were lower in the matched LLR than the matched OLR group (P < 0.001, P = 0.004, P < 0.001 and P < 0.001, respectively). Moreover, post-operative pulmonary and cardiovascular complications were less frequent in the matched LLR group (P = 0.008 and P = 0.014, respectively). In subgroup analysis, among octogenarians, the post-operative major complication rate was lower and hospital stay was shorter in the matched LLR than the matched OLR group (P < 0.001 and P < 0.001, respectively)., Conclusion: LLR for HCC is associated with good short-term outcomes in patients aged ≥ 75 years compared with OLR. LLR is safe and feasible in selected octogenarians with HCC.
