BACKGROUND : Caudate lobectomy via laparoscopic surgery has rarely been described. This multicenter, propensity score-matched study was performed to assess the safety and efficacy of laparoscopic caudate lobectomy (LCL).
METHODS : A multicenter retrospective study was performed including all patients who underwent LCL and open caudate lobectomy (OCL) in four institutions from January 2013 to December 2018. In total, 131 patients were included in this study and divided into LCL (n = 19) and OCL (n = 112) groups. LCLs were matched to OCLs (1:2) using a propensity score matching (PSM) based on nine preoperative variables, including patient demographics and tumor characteristics. The pathological results, perioperative and postoperative parameters, and short-term outcomes were compared between the two groups.
RESULTS : After PSM, there were 18 and 36 patients in the LCL and OCL groups, respectively. Baseline characteristics were comparable after matching. LCL was associated with less blood (100 vs. 300 ml, respectively; P < 0.001) and a shorter postoperative stay (6.0 vs 8.0 days, respectively; P = 0.003). Most patients' resection margins were > 10 mm in the LCL group (P = 0.021), and all patients with malignancy in both groups achieved R0 resection. In terms of early postoperative outcomes, the overall morbidity rate was identical in each group (11.1% vs. 11.1%, respectively; P = 1.000). No mortality occurred in either group.
CONCLUSIONS : Laparoscopy is a feasible choice for resection of tumors located in the caudate lobe with acceptable perioperative results.
