IRON: A retrospective international multicenter study on robotic versus laparoscopic versus open approach in gallbladder cancer

For patients with T1b gallbladder cancer or greater, an adequate lymphadenectomy should include at least 6 nodes. Studies comparing short- and long-term outcomes of the open approach with those of laparoscopy and robotic approaches are limited, with small sample sizes, and there are none comparing l...

Summary:For patients with T1b gallbladder cancer or greater, an adequate lymphadenectomy should include at least 6 nodes. Studies comparing short- and long-term outcomes of the open approach with those of laparoscopy and robotic approaches are limited, with small sample sizes, and there are none comparing laparoscopic and robotic approaches. This study compared patients who underwent robotic, laparoscopic, and open resection of gallbladder cancer, evaluating short- and long-term outcomes. We conducted a multicenter retrospective study of patients with T1b gallbladder cancer or greater (excluding combined organ resection and T4) who underwent open, laparoscopic, and robotic liver resection and lymphadenectomy between January 2012 and December 2022. The 3 groups were matched in terms of patient baseline and disease characteristics based on propensity score matching, comparing robotic with open and robotic with laparoscopic groups. We enrolled 575 patients from 37 institutions. After propensity score matching, the median number of harvested nodes was higher in the robotic group than in the open (7 vs 5; P = .0150) and laparoscopic groups (7 vs 4; P
