Stepwise implementation of robotic surgery in a high volume HPB practice in the Netherlands

Abstract Background Aims of this study were to describe the stepwise implementation and expansion of robotic HPB surgery in a high volume HPB unit in the Netherlands and to analyze clinical outcomes of all robotic liver resections and robotic pancreatoduodenectomies performed within this program. Methods After proctoring by expert international surgeons, HPB surgeons were introduced to robotic liver resection and robotic pancreatoduodenectomy in a stepwise fashion. Data from two prospective databases containing all consecutive patients who underwent robotic liver resection or robotic pancreatoduodenectomy between August 1st, 2015 and March 1st, 2019 were analyzed post hoc. Results In total, 77 consecutive robotic liver resections and 68 consecutive robotic pancreatoduodenectomies were performed. Five surgeons were consecutively introduced to robotic HPB surgery. Mean operative time for robotic liver resection was 160 ± 78 min. Mean operative time for robotic pancreatoduodenectomy was 420 ± 67 min. Operative times remained stable over time and were not affected by the introduction of new surgeons. Conclusion Stepwise implementation and expansion of robotic HPB surgery within one unit over a three-and-half year period is feasible and associated with good clinical outcomes. Despite introducing new surgeons to the technique, operative times, an indicator of the learning process, remained stable over time.
