Abstract Background/purpose This study compared the clinical efficacy and safety of laparoscopic versus open resection for hilar cholangiocarcinoma (HCCA) and analyzed potential prognostic factors. Methods The study included patients who underwent HCCA resection at our center from March 2012 to February 2022. Perioperative complications and postoperative prognosis were compared between the laparoscopic surgery (LS) and open surgery (OS) groups. Results After screening 313 HCCA patients, 68 patients were eligible for the study in the LS group ( n = 40) and OS group ( n = 28). Kaplan-Meier survival curve analysis revealed that overall survival > 2 years and 3-year disease-free survival (DFS) were more common in the LS than OS group, but the rate of 2-year DFS was lower in the LS group than OS group. Cox multivariate regression analysis revealed age (< 65 years), radical resection, and postoperative adjuvant therapy were associated with reduced risk of death (hazard ratio HR = 0.380, 95% confidence interval CI = 0.150–0.940, P = 0.036; HR = 0.080, 95% CI = 0.010–0.710, P = 0.024 and HR = 0.380, 95% CI = 0.150–0.960, P = 0.040), whereas preoperative biliary drainage was an independent factor associated with increased risk of death ( HR = 2.810, 95% CI = 1.130–6.950, P = 0.026). Perineuronal invasion was identified as an independent risk factor affecting DFS ( HR = 5.180, 95% CI = 1.170–22.960, P = 0.030). Conclusions Compared with OS, laparoscopic HCCA resection does not significantly differ in terms of clinical efficacy. Age ( < 65 years), radical resection, and postoperative adjuvant therapy reduce the risk of death, and preoperative biliary drainage increases the risk of death.
