Laparoscopic versus open hepatectomy with or without synchronous colectomy for colorectal liver metastasis: a meta-analysis.

ABSTRACT:

Background

To compare short-term and long-term results of colorectal patients undergoing laparoscopic and open hepatectomy. Moreover, outcomes of laparoscopic versus open procedures for simultaneous primary colorectal tumor and liver metastasis resection were compared.

Methods

A systematic search was conducted in the PubMed and EmBase databases (until Oct. 22. 2013) with no limits. Bibliographic citation management software (EndNote X6) was used for extracted literature management. Quality assessment was performed according to a modification of the Newcastle-Ottawa Scale. The data were analyzed using Review Manager (Version 5.1), and sensitivity analysis was performed by sequentially omitting each study.

Results

Finally, 14 studies, including a total of 975 CLM (colorectal liver metastasis) patients, compared laparoscopic with open hepatectomy. 3 studies of them, including a total of 107 CLM patients, compared laparoscopic with open procedures for synchronous hepatectomy and colectomy. Laparoscopic hepatectomy was associated with a significantly less blood loss, shorter hospitalization time, and less operative transfusion rate. In addition, lower hospital morbidity rate (OR=0.57, 95%CI:0.42-0.78, P=0.0005) and better R0 resection (OR=2.44, 95%CI:1.21-4.94, P=0.01) were observed in laparoscopic hepatectomy. For long-term outcomes, there were no significant differences between two surgical procedures on recurrence and overall survival. In comparison of synchronous hepatectomy and colectomy, laparoscopic procedure displayed shorter hospitalization (MD?=?-3.40, 95%CI:-4.37-2.44, P<0.00001) than open procedure. Other outcomes, including surgical time, estimated blood loss, hospital morbidity, and overall survival did not differ significantly in the comparison.

Conclusions

Laparoscopic hepatectomy with or without synchronous colectomy are acceptable for selective CLM patients. We suggest standard inclusion criteria of CLM patients be formulated.

Project description:BackgroundThe objective of this study was to compare the results of laparoscopic hepatectomy with those of open hepatectomy for colorectal cancer liver metastases (CCLM) using a propensity score matching (PSM) in two university hospital settings.MethodsA patient in the laparoscopic approach (LA) surgery group was randomly matched with another patient in the open approach (OA) group using a 1:1 allocated ratio with the nearest estimated propensity score. No patients of the LA group were excluded for the matching. Matching criteria included age, gender, body mass index (BMI), American society anesthesiologists score, potential co-morbidities, hepatopathies, synchronous or metachronous lesions, size and number of CCLM, preoperative chemotherapy, minor or major liver resections. Intraoperative, postoperative data, and survival were compared in both groups.ResultsFrom January 2012 to January 2015, a total of 242 hepatectomies were consecutively performed, of which 119 for CCLM, namely 101 in the OA group (84.9%) and 18 in the LA group (15.1%). The conversion rate was 5.6% (n=1). The mortality rate was 1% in the OA group and 0% in the LA group. Prior to PSM, there was a statistically significant difference favorable to the LA group regarding operative time, blood loss, length of hospital stay and the rate of medical complications. After PSM, there was no difference regarding operative time or length of hospital stay. However, there was a trend towards less blood loss (P=0.066) and fewer medical complications (44.4% vs.16.7%, P=0.07). The R0 resection rate was 94.4% (n=17) in the two groups. In addition, there was no difference regarding overall survival (P=0.358) and recurrence-free survival [HR =0.99 (0.1-12.7); P=0.99].ConclusionsLaparoscopic liver resections for CCLM seem to yield short- and long-term results, which are similar to open hepatectomies, and could well be considered an alternative to open surgery and become the gold standard in carefully selected patients.

Project description:PurposeThe aim of this study is to investigate the value of total laparoscopic simultaneous colorectal and hepatic resection in patients with synchronous colorectal cancer liver metastases (sCRLMs).MethodssCRLM patients who underwent simultaneous resection from December 2014 to December 2018 in Shanghai Cancer Center, Fudan University were recruited and analyzed retrospectively. The patients were divided into laparoscopic, open, and hybrid surgery groups. The intraoperative information, postoperative short-term outcome, and long-term survival were compared among the three groups. Propensity score matching (PSM) was performed to balance baselines.ResultsA total of 281 patients were recruited. After PSM, 34 patients were selected from both the laparoscopic and the open surgery group. Forty-seven patients were also selected from both the laparoscopic and the hybrid surgery group. The clinicopathologic baselines between the laparoscopic surgery group and the other two groups were well matched. All the operation-related indicators between laparoscopic surgery and hybrid surgery were similar. However, compared with open surgery, laparoscopic surgery showed significantly longer operation time (229.09 ± 10.94 min vs. 192.24 ± 9.49 min, p = 0.013) and less intraoperative blood loss [100.00 (50.00-300.00) ml vs. 200.00 (150.00-400.00) ml, p = 0.021]. For postoperative morbidity, there was no significant difference between the laparoscopic surgery group and the hybrid or the open surgery group (23.40% vs. 31.91% and 17.65% vs. 26.47%, p = 0.356 and p = 0.380). Long-term survival analysis showed that there were no significant differences in all 1-, 3-, and 5-year overall survival, liver recurrence-free survival (RFS), and whole RFS between laparoscopic surgery and hybrid surgery (p = 0.334, p = 0.286, and p = 0.558) or open surgery (p = 0.230, p = 0.348, and p = 0.450).ConclusionsLaparoscopic simultaneous resection for sCRLM shows slight advantages in surgical safety and short-term outcome, and does not compromise long-term survival.

Project description:ImportanceSurgery represents the mainstay treatment of colorectal liver metastases. Indications for the laparoscopic approach in this setting have been widened and there is a need to confirm the benefits of minimally invasive liver surgery (MILS) in patients with complex disease states.ObjectiveTo compare outcomes of laparoscopic surgery with those of open surgery for liver metastases from colorectal cancer, focusing on the characteristics of modern MILS and therefore overcoming possible selection bias related to different policies for patients' eligibility for MILS over time.Design, setting, and participantsA cohort study of 885 resections performed for liver metastases from colorectal cancer between January 1, 2004, and June 30, 2017, at the Hepatobiliary Surgery Unit of San Raffaele Hospital, Milano, Italy, comprising 187 laparoscopic and 698 open resections. Procedures performed using the MILS approach with a ratio of MILS to total resections per year of more than 30% were considered and were matched by propensity scores (ratio of 1:4) to procedures performed using the open approach with a ratio of MILS to total resections per year of less than 30%.Main outcomes and measuresThe primary end point was short-term outcomes, including morbidity, mortality, functional recovery, and interval between surgery and adjuvant treatments; the secondary end point was long-term outcomes.ResultsAmong this cohort (104 patients in the MILS group; 46 women and 58 men; median age, 62 years [range, 35-81 years]; and 412 patients in the open group; 181 women and 231 men; median age, 60 years [range, 37-80 years]), primary end-point data showed a significantly higher incidence of postoperative morbidity in patients who underwent open resections compared with those who underwent MILS (94 [22.8%] vs 21 [20.2%]; P = .04). Patients in the MILS group had fewer major complications (Dindo-Clavien grades III-V) compared with patients in the open group (Dindo-Clavien grades III-V; 7 [6.7%] vs 35 [8.5%]; P = .03) as well as shorter lengths of stay (median [range] duration, 3 [2-35] vs 5 [4-37] days; P = .02). Oncologic results were not compromised by the laparoscopic approach.Conclusions and relevanceIn this study, the results of the propensity score matching analysis between modern laparoscopic surgery and previous open surgery appear to confer more comparable cohorts for complexity, further supporting the advantages of laparoscopy in the surgical treatment of liver metastases from colorectal cancer. The increase in use that laparoscopy has experienced appears to be based on increased feasibility, widening of eligibility criteria for patients, enhanced clinical effectiveness, and oncologic outcomes. All these elements together suggest that up to 70% of patients appear to be candidates for this minimally invasive surgical approach in high-volume centers.
