Abstract

Insights

Minimally invasive pancreatoduodenectomy (MIPD) offers improved lymphadenectomy rates and shorter hospital stays compared to open procedures. Oncological outcomes and survival remain comparable between MIPD and open pancreatoduodenectomy (OPD).

Area of Science:

  • Surgical Oncology
  • Gastrointestinal Surgery
  • Minimally Invasive Surgery

Background:

  • Minimally invasive pancreatoduodenectomy (MIPD) adoption is rising, yet multicenter data on its oncological outcomes is limited.
  • Existing evidence often comes from single-center, high-volume institutions, necessitating broader investigation.
  • The comparative impact of MIPD versus open pancreatoduodenectomy (OPD) in a real-world, multicenter setting requires further clarification.

Purpose of the Study:

  • To evaluate the oncological and perioperative outcomes of MIPD compared to OPD.
  • To assess the impact of surgical approach on lymphadenectomy adequacy, surgical margins, and survival.
  • To analyze trends in MIPD adoption and outcomes over time in a multicenter setting.

Main Methods:

  • A propensity score matching analysis was conducted using the National Cancer Database (2010-2016).
  • Patients undergoing pancreatoduodenectomy for ductal adenocarcinoma were included (n=10,246).
  • Primary outcomes: lymphadenectomy (≥15 nodes) and surgical margins; Secondary outcomes: 90-day mortality, length of stay, and overall survival.

Main Results:

  • MIPD was associated with a significantly higher rate of adequate lymphadenectomy (≥15 nodes) compared to OPD (68.4% vs 62.5%, P<.0001).
  • No significant differences were observed in positive surgical margins, 90-day mortality, or overall survival between MIPD and OPD.
  • OPD was linked to a longer length of stay (>10 days) compared to MIPD (36.6% vs 33%, P<.01).
  • Trends showed increased adequate lymphadenectomy and decreased conversion rates to OPD over the study period for MIPD.

Conclusions:

  • MIPD is associated with superior lymphadenectomy adequacy and shorter hospital stays compared to OPD.
  • Oncological outcomes, including surgical margins and overall survival, are similar between MIPD and OPD.
  • The findings support MIPD as a viable alternative to OPD, with improving outcomes over time.
