Background: While minimally invasive surgery (MIS) to treat liver tumors has increased, data on perioperative outcomes of MIS relative to open liver resection (O-LR) are lacking. We sought to compare short-term outcomes among patients undergoing MIS vs. O-LR in a nationally representative database. Methods: The National Surgical Quality Improvement Program database was used to identify patients undergoing hepatectomy between January 1 and December 31, 2014. Propensity score matching algorithm was used to balance differences in baseline characteristics among MIS and O-LR groups. Results: A total of 3064 patients were included in the study. After propensity matching, the baseline characteristics for O-LR and MIS groups were comparable (minimum p value = 0.12). Incidence of superficial surgical site infections, intraoperative or postoperative blood transfusions, and pulmonary embolism was lower among patients in MIS group compared to O-LR (p < 0.02). Liver failure and biliary leakage were also less frequent among patients undergoing MIS (p < 0.01). Similarly, MIS was associated with a shorter length of hospital stay (LOS) compared to O-LR (p < 0.001). Of note, 30-day postoperative mortality and readmission were comparable between the two groups. Conclusions: Patients undergoing MIS had a lower postoperative morbidity and shorter LOS compared with patients undergoing O-LR. MIS is safe and may be associated with improved short-term outcomes following hepatic surgery.
