Short-term postoperative outcomes after liver resection in the elderly patient: a nationwide population-based study

Efficacy and Safety of Surgical Resection in Elderly Patients with Hepatocellular Carcinoma: A Systematic Review and Meta-Analysis

Background/Aims

: With increased life expectancy, the management of elderly hepatocellular carcinoma (HCC) patients became a crucial issue, yet it is still challenging due to comorbidities and high surgical risks. While surgical resection is considered as primary treatment for eligible HCC patients, systematic evidence on its outcomes in elderly patients remains scarce. In this review, we aimed to analyze the efficacy and safety outcomes of surgical resection in elderly HCC patients.

Methods

: The studies included in this meta-analysis were selected from Ovid-MEDLINE, Ovid-Embase, CENTRAL, KoreaMed, KMbase, and KISS databases following a predefined protocol. Efficacy outcomes included overall survival and disease-free survival, while the safety outcomes included postoperative mortality and complications.

Results

: Patients in the elderly group (≥65 years) who underwent surgery exhibited non-inferior overall survival (hazard ratio [HR], 1.26; 95% confidence interval [CI], 0.92 to 1.74) and disease-free survival (HR, 1.03; 95% CI, 0.99 to 1.08) compared to the non-elderly group. Overall postoperative mortality exhibited no statistical difference (odds ratio [OR], 1.07; 95% CI, 0.87 to 1.31), but 30-day, 90-day, and in-hospital mortality were higher in the elderly group. The incidence of overall complications was higher in the elderly group (OR, 1.44; 95% CI, 1.22 to 1.69). Sensitivity analysis for the super elderly group (≥80 years) showed significantly higher in-hospital mortality compared to the non-super elderly group (OR, 2.51; 95% CI, 1.16 to 5.45).

Conclusions

: The efficacy outcome of surgical resection in the elderly HCC patients was not worse than that in the non-elderly HCC patients, while in-hospital mortality and complications rates were higher. Therefore, surgical resection should be purposefully considered in the elderly population, with careful candidate selection.

Safety and feasibility of liver resection including major hepatectomy for geriatric patients with hepatocellular carcinoma: a retrospective observational study

BACKGROUND

It is unclear whether hepatectomy, which ranges in invasiveness from partial to major hepatectomy, is safe and feasible for older adult patients. Therefore, we compared its postoperative complications and long-term outcomes between younger and older adult patients.

METHODS

Patients who underwent hepatectomies for hepatocellular carcinoma (N = 883) were evaluated. Patients were divided into two groups: aged < 75 years (N = 593) and ≥ 75 years (N = 290). Short-term outcomes and prognoses were compared between the groups in the entire cohort. The same analyses were performed for the major hepatectomy cohort.

RESULTS

In the entire cohort, no significant differences were found in complications between patients aged < 75 and ≥ 75 years, and the multivariate analysis did not reveal age as a prognostic factor for postoperative complications. However, overall survival was significantly worse in older patients, although no significant differences were noted in time to recurrence or cancer-specific survival. In the multivariate analyses of time to recurrence, overall survival, and cancer-specific survival, although older age was an independent poor prognostic factor for overall survival, it was not a prognostic factor for time to recurrence and cancer-specific survival. In the major hepatectomy subgroup, short- and long-term outcomes, including time to recurrence, overall survival, and cancer-specific survival, did not differ significantly between the age groups. In the multivariate analysis, age was not a significant prognostic factor for complications, time to recurrence, overall survival, or cancer-specific survival.

CONCLUSION

Hepatectomy, including minor and major hepatectomy, may be safe and oncologically feasible options for selected older adult patients with hepatocellular carcinoma.

Outcomes of liver surgery: A decade of mandatory nationwide auditing in the Netherlands

BACKGROUND

In 2013, the nationwide Dutch Hepato Biliary Audit (DHBA) was initiated. The aim of this study was to evaluate changes in indications for and outcomes of liver surgery in the last decade.

METHODS

This nationwide study included all patients who underwent liver surgery for four indications, including colorectal liver metastases (CRLM), hepatocellular carcinoma (HCC), and intrahepatic- and perihilar cholangiocarcinoma (iCCA - pCCA) between 2014 and 2022. Trends in postoperative outcomes were evaluated separately for each indication using multilevel multivariable logistic regression analyses.

RESULTS

This study included 8057 procedures for CRLM, 838 for HCC, 290 for iCCA, and 300 for pCCA. Over time, these patients had higher risk profiles (more ASA-III patients and more comorbidities). Adjusted mortality decreased over time for CRLM, HCC and iCCA, respectively aOR 0.83, 95%CI 0.75-0.92, P < 0.001; aOR 0.86, 95%CI 0.75-0.99, P = 0.045; aOR 0.40, 95%CI 0.20-0.73, P < 0.001. Failure to rescue (FTR) also decreased for these groups, respectively aOR 0.84, 95%CI 0.76-0.93, P = 0.001; aOR 0.81, 95%CI 0.68-0.97, P = 0.024; aOR 0.29, 95%CI 0.08-0.84, P = 0.021). For iCCA severe complications (aOR 0.65 95%CI 0.43-0.99, P = 0.043) also decreased. No significant outcome differences were observed in pCCA. The number of centres performing liver resections decreased from 26 to 22 between 2014 and 2022, while median annual volumes did not change (40-49, P = 0.66).

CONCLUSION

Over time, postoperative mortality and FTR decreased after liver surgery, despite treating higher-risk patients. The DHBA continues its focus on providing feedback and benchmark results to further enhance outcomes.

Extended Right Hepatectomy following Clearance of the Left Liver Lobe and Portal Vein Embolization for Curatively Intended Treatment of Extensive Bilobar Colorectal Liver Metastases: A Single-Center Case Series

BACKGROUND

Two-staged hepatectomy (TSH) including portal vein embolization (PVE) may offer surgical treatment for extensive bilobar colorectal liver metastases (CRLM). This study aimed to investigate the feasibility and outcomes of extended right hepatectomy (ERH) within TSH including PVE for patients with extended CRLM.

METHODS

We retrospectively collected data of patients who underwent TSH for extended CRLM between 2015 and 2021 at our institution. Clearance of the left liver lobe (clear-up, CU) associated with PVE was followed by ERH.

RESULTS

Minimally invasive (n = 12, 46%, MIH) or open hepatectomy (n = 14, 54%, OH) was performed. Postoperative major morbidity and 90-day mortality were 54% and 0%. Three-year overall survival was 95%. Baseline characteristics, postoperative and long-term outcomes were comparable between MIH and OH. However, hospital stay was significantly shorter after MIH (8 vs. 15 days, p = 0.008). Additionally, the need for intraoperative transfusions tended to be lower in the MIH group (17% vs. 50%, p = 0.110).

CONCLUSIONS

ERH following CU and PVE for extended CRLM is feasible and safe in laparoscopic and open approaches. MIH for ERH may result in shorter postoperative hospital stays. Further high-volume, multicenter studies are required to evaluate the potential superiority of MIH.

Postoperative Liver Failure: Definitions, Risk factors, Prediction Models and Prevention Strategies

BACKGROUND

Liver resection is the treatment for a variety of benign and malignant conditions. Despite advances in preoperative selection, surgical technique, and perioperative management, post hepatectomy liver failure (PHLF) is still a leading cause of morbidity and mortality following liver resection.

METHODS

A review of the literature was performed utilizing MEDLINE/PubMed and Web of Science databases in May of 2023. The MESH terms "liver failure," "liver insufficiency," and "hepatic failure" in combination with "liver surgery," "liver resection," and "hepatectomy" were searched in the title and/or abstract. The references of relevant articles were reviewed to identify additional eligible publications.

RESULTS

PHLF can have devastating physiological consequences. In general, risk factors can be categorized as patient-related, primary liver function-related, or perioperative factors. Currently, no effective treatment options are available and the management of PHLF is largely supportive. Therefore, identifying risk factors and preventative strategies for PHLF is paramount. Ensuring an adequate future liver remnant is important to mitigate risk of PHLF. Dynamic liver function tests provide more objective assessment of liver function based on the metabolic capacity of the liver and have the advantage of easy administration, low cost, and easy reproducibility.

CONCLUSION

Given the absence of randomized data specifically related to the management of PHLF, current strategies are based on the principles of management of acute liver failure from any cause. In addition, goal-directed therapy for organ dysfunction, as well as identification and treatment of reversible factors in the postoperative period are critical.

Personalized multimodal prehabilitation reduces cardiopulmonary complications after pancreatoduodenectomy: results of a propensity score matching analysis

BACKGROUND

The purpose of prehabilitation is to improve postoperative outcomes by increasing patients' resilience against the stress of surgery. This study investigates the effect of personalized multimodal prehabilitation on patients undergoing pancreatoduodenectomy.

METHODS

Included patients were screened for six modifiable risk factors: (1) low physical fitness, (2) malnutrition, (3) low mental resilience, (4) anemia and hyperglycemia, (5) frailty, and (6) substance abuse. Interventions were performed as needed. Using 1:1 propensity score matching (PSM), patients were compared to a historical cohort.

RESULTS

From 120 patients, 77 (64.2%) performed a cardiopulmonary exercise test to assess their physical fitness and provide them with a preoperative training advice. Furthermore, 88 (73.3%) patients received nutritional support, 15 (12.5%) mental support, 17 (14.2%) iron supplementation to correct for iron deficiency, 18 (15%) regulation support for hyperglycemia, 14 (11.7%) a comprehensive geriatric assessment, and 19 (15.8%) substance abuse support. Of all patients, 63% required ≥2 prehabilitation interventions. Fewer cardiopulmonary complications were observed in the prehabilitation cohort (9.2% versus 23.3%; p = 0.002). In surgical outcomes and length of stay no differences were observed.

CONCLUSION

Our prehabilitation program is effective in detecting risk factors in patients; most patients required multiple interventions. Consequently, a reduction in cardiopulmonary complications was observed.

Implementation and Outcome of Robotic Liver Surgery in the Netherlands: A Nationwide Analysis

OBJECTIVE

To determine the nationwide implementation and surgical outcome of minor and major robotic liver surgery (RLS) and assess the first phase of implementation of RLS during the learning curve.

BACKGROUND

RLS may be a valuable alternative to laparoscopic liver surgery. Nationwide population-based studies with data on implementation and outcome of RLS are lacking.

METHODS

Multicenter retrospective cohort study including consecutive patients who underwent RLS for all indications in 9 Dutch centers (August 2014-March 2021). Data on all liver resections were obtained from the mandatory nationwide Dutch Hepato Biliary Audit (DHBA) including data from all 27 centers for liver surgery in the Netherlands. Outcomes were stratified for minor, technically major, and anatomically major RLS. Learning curve effect was assessed using cumulative sum analysis for blood loss.

RESULTS

Of 9437 liver resections, 400 were RLS (4.2%) procedures including 207 minor (52.2%), 141 technically major (35.3%), and 52 anatomically major (13%). The nationwide use of RLS increased from 0.2% in 2014 to 11.9% in 2020. The proportion of RLS among all minimally invasive liver resections increased from 2% to 28%. Median blood loss was 150 mL (interquartile range 50-350 mL] and the conversion rate 6.3% (n=25). The rate of Clavien-Dindo grade ≥III complications was 7.0% (n=27), median length of hospital stay 4 days (interquartile range 2-5) and 30-day/in-hospital mortality 0.8% (n=3). The R0 resection rate was 83.2% (n=263). Cumulative sum analysis for blood loss found a learning curve of at least 33 major RLS procedures.

CONCLUSIONS

The nationwide use of RLS in the Netherlands has increased rapidly with currently one-tenth of all liver resections and one-fourth of all minimally invasive liver resections being performed robotically. Although surgical outcomes of RLS in selected patient seem favorable, future prospective studies should determine its added value.

Oncologic Liver Resections in a Geriatric Population: Peri-operative, Long-Term and Quality-of-Life Outcomes-Experience from a High-Volume Centre in India

BACKGROUND

Elderly patients can often be overlooked as candidates for a major hepatic resection, by virtue of their age. To enable better patient selection for hepatic resections in this age group, we analysed the outcomes of liver resections in elderly patients to identify any potential prognostic factors.

METHODS

We conducted a retrospective review of a prospectively maintained database of hepatic resections from 1 January 2010 to 31 October 2021 and analysed the post-operative outcomes in patients aged 65 years or older. Short-term outcomes were analysed in terms of length of hospital stay, 90-day major morbidity, and 90-day mortality. Long-term outcome was defined by the disease-free survival, overall survival and quality of life.

RESULTS

Over a period of 11 years, 170 elderly patients underwent oncologic liver resections, of which 68 (40%) underwent a major hepatectomy. The overall morbidity and mortality rates were 32.8% and 5.3%, respectively. Extent of hepatic resection, increasing age, concomitant resection of other organs and a biliary-enteric anastomosis were independent predictors for poor immediate post-operative outcomes. Median disease-free survival and overall survival were 30 months and 78 months, respectively. The global health status was excellent in majority of patients with a mean score of 88.62.

CONCLUSION

Major oncologic liver resections can be performed in well-selected geriatric population with acceptable peri-operative, long-term and quality-of-life outcomes.

Extended length of stay in diabetic octogenarians following revision total hip arthroplasty

PURPOSE

Past research has shown diabetic patients, including those of geriatric age, to be at an increased risk of postoperative complications following various surgeries, including revision total hip arthroplasty (rTHA). However, whether these risks are disproportionately greater in octogenarian patients has not been well investigated. This study aimed to determine whether diabetic octogenarians are at an increased risk of postoperative complications following rTHA.

METHODS

The national surgical quality improvement program database was used to identify all diabetic patients who underwent rTHA from 2007 to 2018. Patients were divided into two groups: an aged 65 to 79 cohort and an aged 80 to 89 cohort. Patient demographics, comorbidities, and postoperative complications were assessed and compared between the two aged cohorts, with the utilization of bivariate and multivariate analyses.

RESULTS

Of the 1184 diabetic patients who underwent rTHA, 906 (76.5%) patients were in the aged 65 to 79 cohort and 278 (23.5%) patients were in the aged 80 to 89 cohort. After adjusting for patient demographics and medical comorbidities, compared to patients in the aged 65 to 79 group, diabetic patients who were 80 to 89 years old were found to have an increased risk of extended length of hospital stay (OR 1.67; p = 0.017).

CONCLUSION

Diabetic octogenarian patients have an increased risk for a prolonged hospital stay following rTHA relative to their younger diabetic geriatric counterparts. Orthopedic surgeons should be aware of these increased risks to properly educate diabetic octogenarians and assist in surgical management decision making in these patients considering rTHA.
