Purpose: This study assessed the impact of 2D and 3D environments by comparing pediatric surgeons (PS) and gastrointestinal surgeons (GIS) using a laparoscopic hepaticojejunostomy simulator.Methods: We developed a high-fidelity simulator of laparoscopic hepaticojejunostomy. Thirty-five participants (19 PS and 16 GIS) performed hepaticojejunostomy in both 2D and 3D environments. We evaluated the required time, total path length, and average velocities of bilateral forceps in both situations using the para-axial port layout.Results: Regarding the participants’ characteristics, the performance history of laparoscopic hepaticojejunostomy differed significantly between PS and GIS. In PS, the 3D environment did not markedly affect compared with 2D. In GIS, however, the 3D environment affected the time and movement of the right forceps. There were no significant differences in the time between PS and GIS in either environment. In both environments, the right-hand movement of the PS group was shorter and slower than that of the GIS group, but the left-hand movement was the opposite.Conclusion: There were significant differences in forceps movement characteristics between the PS and GIS. The effects of a 3D environment could not be clarified in this study, because it may depend on the port layout used and the operative procedures.Koji Yamada, Masakazu Murakami, Keisuke Yano, Tokuro Baba, Toshio Harumatsu, Shun Onishi, Waka Yamada, Ryuta Masuya, Seiro Machigashira, Kazuhiko Nakame, Motoi Mukai, Tatsuru Kaji, Satoshi IeiriImpact and characteristics of two‑ and three‑dimensional forceps manipulation using laparoscopic hepaticojejunostomy mimicking a disease‑specific simulator: a comparison of pediatric surgeons with gastrointestinal surgeonsPediatric Surgery International (2019) 35:1051–1057This is a post-peer-review, pre-copyedit version of an article published in Pediatric Surgery InternationalThe final authenticated version is available online at:https://doi.org/10.1007/s00383-019-04538-6
