There is a lack of consensus on the definition of upfront resectability and use of perioperative systemic therapy for colorectal liver metastases (CRLM). This survey aimed to summarize the current treatment strategies for upfront resectable CRLM throughout Europe. A survey was sent to all members of the European-African Hepato-Pancreato-Biliary Association to gain insight into the current views on resectability and the use of systemic therapy for upfront resectable CRLM. The survey was completed by 87 surgeons from 24 countries. The resectability of CRLM is mostly based on the volume of the future liver remnant, while considering tumor biology. Thermal ablation was considered as an acceptable adjunct to resection in parenchymal-sparing CRLM surgery by 77 % of the respondents. A total of 40.2 % of the respondents preferred standard perioperative systemic therapy and 24.1 % preferred standard upfront local treatment. Among the participating European hepato-pancreato-biliary surgeons, there is a high degree of consensus on the definition of CRLM resectability. However, there is much variety in the use of adjunctive thermal ablation. Major variations persist in the use of perioperative systemic therapy in cases of upfront resectable CRLM, stressing the need for further evidence and a consensus. [ABSTRACT FROM AUTHOR]

Background: First seen as an innovation for select patients, laparoscopic liver resection (LLR) has evolved since its introduction, resulting in worldwide use. Despite this, it is still limited mainly to referral centers. The aim of this study was to evaluate a large cohort undergoing LLR from 2000 to 2015, focusing on the technical approaches, perioperative and oncologic outcomes, and evolution of practice over time.Study Design: The demographics and indications, intraoperative, perioperative, and oncologic outcomes of 2,238 patients were evaluated. Trends in practice and outcomes over time were assessed.Results: The percentage of LLR performed yearly has increased from 5% in 2000 to 43% in 2015. Pure laparoscopy was used in 98.3% of cases. Wedge resections were the most common operation; they were predominant at the beginning of LLR and then decreased and remained steady at approximately 53%. Major hepatectomies were initially uncommon, then increased and reached a stable level at approximately 16%. Overall, 410 patients underwent resection in the posterosuperior segments; these were more frequent with time, and the highest percentage was in 2015 (26%). Blood loss, operative time, and conversion rate improved significantly with time. The 5-year overall survival rates were 73% and 54% for hepatocellular carcinoma (HCC) and colorectal liver metastases (CRLM), respectively. The 5-year, recurrence-free survival rates were 50% and 37% for HCC and CRLM, respectively.Conclusions: Since laparoscopy was introduced, a long implementation process has been necessary to allow for standardization and improvement in surgical care, mastery of the technique, and the ability to obtain good perioperative results with safe oncologic outcomes.

Background: Laparoscopic liver surgery is expanding. Most laparoscopic liver resections for colorectal carcinoma metastases are performed subsequent to the resection of the colorectal primary, raising concerns about the feasibility and safety of advanced laparoscopic liver surgery in the context of an abdomen with possible postoperative adhesions. The aim was to compare the outcome of laparoscopic hepatectomy for colorectal metastases after open versus laparoscopic colorectal surgery., Methods: This observational, multicenter study reviewed 394 patients undergoing laparoscopic minor and major liver resection for colorectal carcinoma metastases. Main outcome measures were intraoperative unfavorable incidents and short-term results in patients who had previous open versus laparoscopic colorectal cancer surgery., Results: Three hundred six patients (78%) had prior open and 88 (22%) had prior laparoscopic colorectal resection. Laparoscopic major hepatectomies were undertaken in 63 (16%). Intraoperative unfavorable incidents during laparoscopic liver surgery were significantly higher among patients who had prior open colorectal surgery (26%) compared with the laparoscopic group (14%; P = .017). Positive resection margins and postoperative complications were not associated with the approach adopted for the resection of the primary cancer. On multivariate logistic regression analysis, intraoperative unfavorable incidents were associated significantly only with prior open colorectal surgery (odds ratio, 2.8; P = .006) and laparoscopic major hepatectomy (odds ratio, 2.4; P = .009)., Conclusion: Laparoscopic minor hepatectomy can be performed safely in patients who have undergone previous open colorectal surgery. Laparoscopic major hepatectomy after open colorectal surgery may be challenging. Careful risk assessment in the decision-making process is required not to compromise patient safety and to guarantee the expected benefits from the minimally invasive approach., (Copyright © 2015 Elsevier Inc.
