Background: Laparoscopic liver resection (LLR) is proposed as an alternative to open liver resection (OLR) for treatment of liver tumors. The aim of this study was to compare the surgical and oncological outcomes of LLR versus OLR in benign and malignant solid liver tumors. Study Design: In this case-matched study, charts of 497 patients with liver lesions who had LLR or OLR in our center were retrospectively reviewed. Among them, 54 consecutive patients with benign or malignant solid liver tumors who had LLR were matched with a similar number of patients with OLR based on the pathology and extent of liver resection. Additionally, the surgical and oncological outcomes such as operating room time, amount of blood transfusion requirement, free resection margin rate, length of hospital stay, complication rate, perioperative mortality, and survival were compared between the two groups. Results: Demographics, pathological characteristics of the tumor, and extent of liver resection were similar between the two groups. Twenty-nine (54%) patients in each group had malignant lesions. There were no statistically significant differences between the two groups in terms of operating room time, amount of blood transfusion requirement, free resection margin, or postoperative complication rate or survival. However, hospital stay was significantly shorter in the laparoscopic group (5.9 versus 9 days, P=.006). Although no perioperative mortality was observed in patients with benign tumors, among the patients with malignant tumors, 2 died perioperatively in each group. Conclusions: Our results in accordance with previous studies demonstrated that although the oncological outcomes of LLR and OLR were comparable, LLR patients had a shorter hospital stay.
