Minimally invasive pancreatoduodenectomy by junior surgeon: Initial experience of the next generation

Background: Several guidelines exist for minimally invasive pancreatoduodenectomy (MIPD) regarding its prerequisites and learning curve. However, these guidelines are based on the experience of the pioneers of MIPD; minimal data exist on the experience of the next generation of surgeons. The aim of this study was to compare the two surgeon types (veteran and junior) for MIPD in terms of immediate postoperative outcomes. Methods: The postoperative outcomes of 22 patients who underwent robot-assisted pancreatoduodenectomy (RAPD) by a junior surgeon from July 2021 to December 2022 were retrospectively reviewed. The outcomes were compared with the initial postoperative outcomes and the contemporary postoperative outcomes of RAPD by a veteran surgeon. Results: In comparing the initial outcomes between the two surgeon types, the veteran surgeons showed a shorter operation time (junior surgeon vs. veteran surgeon: 606 ± 89 vs. 467 ± 77 min, p < 0.001). However, there was no significant difference in terms of postoperative outcomes, such as blood loss (300 [200–600] ml. vs. 200 [100–500] ml, p = 0.208), major complications (≥CDC IIIa: 4 (18.2%) vs. 4 (18.2%), p = 1.000), postoperative pancreatic fistula (POPF; ≥ISGPF Grade B: 2 (9.1%) vs. 3 (13.6%), p > 0.999), and length of hospital stay (18.0 ± 8.9 days vs. 18.3 ± 7.9 days, p = 0.915), between the two surgeon types. In addition, in a comparison of the contemporary outcomes, there was no significant difference in terms of postoperative outcome (complications: 4 (18.2%) vs 11 (11.1%), p = 0.580; POPF: 2 (9.1%) vs. 3 (3.0%), p = 0.484; length of hospital stay: 18.0 ± 8.9 vs. 15.0 ± 6.5 days, p = 0.065). Conclusion: The initial outcomes of MIPD by a well-trained junior surgeon were found to be comparable to those of MIPD by a veteran surgeon.
