Background:This study aimed to evaluate the perioperative outcomes of patients with benign and malignant liver lesions scheduled for laparoscopic and open surgery using a propensity score-matched approach to analyze additional cofactors influencing outcomes. Patients and Methods:In this study, we retrospectively reviewed 270 patients who underwent laparoscopic or open liver resection at our institute between October 2016 and November 2021. Patients were divided into open and laparoscopic liver resection groups and compared according to the intention to treat principle. In the purification process for the nonrandom nature of the study, a matching analysis was performed at a 1:1 case-control ratio. The PS model included selected data on body mass index, additional data on the American Society of Anesthesiology score, cirrhosis, lesion <2 cm from the hilum, lesion <2 cm from the hepatic vein or inferior vena cava, and type of neoadjuvant chemotherapy. Results:The operation time and 30- and 90-day mortality rates were similar between the groups. The average length of hospital stay was 11 days in the open surgery group and 9 days in the laparoscopic surgery group after matching (P=0.011). The 30-day morbidity rate was statistically different between the groups before and after matching, favoring the laparoscopic group (P=0.001 and 0.006, respectively). After the propensity score-matched approch, the open group's Pringle time was shorter than that of the laparoscopic group. The total operative time was longer in the laparoscopic than in the open surgery group. This did not change after matching (300 vs. 240 min). Conclusions:Laparoscopic surgery is a feasible and safe treatment option for patients with liver tumors, with promising results in terms of morbidity and hospital stay.
