Background: This multicenter study aimed to compare the clinical outcomes of minimally invasive extended cholecystectomy (MI-EC) versus open EC (O-EC) for patients with gallbladder cancer (GBC). Methods: Patients who underwent EC (cholecystectomy, wedge resection of the liver bed, and regional lymphadenectomy) for GBC between 2010 and 2020 in three centers were included in the study. The clinicopathological data were compared after propensity score matching. Additional subgroup analysis on laparoscopic and robotic EC (L-EC and R-EC) was performed. Results: A total of 377 patients were included: 308 for O-EC and 69 for MI-EC, respectively. The MI-EC group had a longer operative time (188.9 vs. 238.1 min, p < .001) and shorter hospital stay (9.0 vs. 7.2 days, p = .007), although no differences were found in operative blood loss, complication rate and survival outcome. In subgroup analysis, L-EC patients had a longer operative time (264.4 vs. 202.0 min, p = .001), compared to R-EC patients with comparable perioperative and survival outcomes. Conclusion: Although patients with MI-EC had a longer operation time and higher medical costs, the advantages were enhanced recovery with comparable short- and long-term outcomes. The operation time was less for R-EC patients than for L-EC patients, though the high cost still remains. The surgery type for EC can be selected according to the patient's condition, social status and surgeon's preference.
