Safety and Efficacy of an Enhanced Recovery Protocol After Hepatic Resection

Value of sarcopenia in the resection of colorectal liver metastases-a systematic review and meta-analysis

Introduction

Sarcopenia is defined as a decline in muscle function as well as muscle mass. Sarcopenia itself and sarcopenic obesity, defined as sarcopenia in obese patients, have been used as surrogates for a worse prognosis in colorectal cancer. This review aims to determine if there is evidence for sarcopenia as a prognostic parameter in colorectal liver metastases (CRLM).

Methods

PubMed, Embase, Cochrane Central, Web of Science, SCOPUS, and CINAHL databases were searched for articles that were selected in accordance with the PRISMA guidelines. The primary outcomes were overall survival (OS) and disease-free survival (DFS). A random effects meta-analysis was conducted.

Results

After eliminating duplicates and screening abstracts (n = 111), 949 studies were screened, and 33 publications met the inclusion criteria. Of them, 15 were selected after close paper review, and 10 were incorporated into the meta-analysis, which comprised 825 patients. No significant influence of sarcopenia for OS (odds ratio (OR), 2.802 (95% confidence interval (CI), 1.094-1.11); p = 0.4) or DFS (OR, 1.203 (95% CI, 1.162-1.208); p = 0.5) was found, although a trend was defined toward sarcopenia. Sarcopenia significantly influenced postoperative complication rates (OR, 7.905 (95% CI, 1.876-3.32); p = 0.001) in two studies where data were available.

Conclusion

Existing evidence on the influence of sarcopenia on postoperative OS as well as DFS in patients undergoing resection for CRLM exists. We were not able to confirm that sarcopenic patients have a significantly worse OS and DFS in our analysis, although a trend toward this hypothesis was visible. Sarcopenia seems to influence complication rates but prospective studies are needed.

Association between achieving textbook outcomes and better survival after laparoscopic liver resection in the anterolateral segments in patients with hepatocellular carcinoma

BACKGROUND

The quality of surgical procedures are assessed by textbook outcomes (TO). LLR is considered a standard treatment for HCC in the anterolateral segments of the liver. The main objective of this study was to evaluate the factors affecting achievement of TO for laparoscopic liver resection (LLR) and its impact on survival.

METHODS

We conducted a retrospective cohort study of patients who underwent LLR for lesions located in the anterolateral segments (n=309). Patients were divided into TO and non-TO group.

RESULTS

A TO was achieved in 55.0% of patients (n=170). In multivariable analysis, Model for End-stage Liver Disease (MELD) score >10 (odds ratio[OR] 3.076; 95% confidence interval[CI] 1.134-8.342), absence of diabetes mellitus (OR 2.325; 95% CI 1.227-4.407) and thrombocytopenia (OR 2.115; 95% CI 1.134-8.342) were independently associated with not achieving TO. The 5-year overall (82.9% vs. 72.8%, P=0.017) and recurrence-free (48.8% vs. 35.4%; P=0.036) survival rates were significantly greater in the TO group than in the non-TO group.

CONCLUSION

The MELD score, thrombocytopenia, and hypoalbuminemia were independent risk factors influencing the achievement of TO. TO influences the short- and long-term outcomes after LLR for HCC.
