Abstract
Background
Findings have shown laparoscopic liver resection (LLR) to be feasible and safe, but the data in the literature regarding oncologic outcomes are scant. This study aimed to compare the perioperative and short-term oncologic outcomes between LLR and open resection of colorectal liver metastasis (CLM).
Methods
Between January 2006 and April 2012, 40 patients underwent LLR of CLM. These patients were compared with a consecutive matched group of 40 patients who underwent open resection within the same period. Data were obtained from a prospective institutional review board (IRB)-approved database. Statistical analysis was performed using t test, Chi-square, and Kaplan–Meier survival.
Results
The groups were similar in terms of age, gender, tumor size, number of tumors, and type of resections performed. The operative time was similar in the two groups, but the estimated blood loss was less in the LLR group than in the open resection group. The length of stay was shorter in the LLR group (3.7 vs 6.5 days; p < 0.001). The 2-year overall survival rate was 89 % for LLR and 81 % for open resection. The median disease-free survival time was 23 months in each group.
Conclusions
The findings suggest that LLR is associated with less blood loss and a shorter hospital stay than open resection for CLM. According to our short-term results, LLR is equivalent to open resection in terms of oncologic outcomes.
