Background The objective was to elucidate the operative technique of robotic radical cholecystectomy (RRC) and to compare the early outcomes of RRC with open radical cholecystectomy (ORC) for gallbladder cancer (GBC). Methods Patients who underwent RRC for suspected or incidental GBC between July 2015 and August 2018 were analyzed. Patients who underwent ORC during the same period and fulfilled the study criteria formed the control group. Results During the study period, 27 patients who underwent RRC formed the study group (group A) and 70 matched patients who underwent ORC formed the control group (group B). Median surgical time was higher in group A (295 vs 200 minutes, P < 0.001). However, median blood loss (200 vs 600 mL, P < 0.001), postoperative hospital stay (4 vs 5 days, P = 0.046) and postoperative morbidity (1 vs 15 patients, P = 0.035) were lower in group A. Median lymph node yield was 10 (range = 2‐21) for group A and 9 (range = 2‐25) for group B, and was comparable (P = 0.408). During a median follow up of 9 (1‐46) months, two patients in group A developed recurrence (no port site recurrence). Conclusion RRC is safe and feasible and the short‐term results are compared with ORC.

In carefully selected patients of GB NECs, downsizing with NACT facilitates radical resection with negative margins.
