Robot-Assisted Pancreatoduodenectomy: Annals of Surgery | August 2026

Introduction:

Robot-assisted pancreatoduodenectomy (RPD) is increasingly adopted in high-volume pancreatic centers, but concerns remain regarding its higher operative and equipment costs compared with open pancreatoduodenectomy (OPD). This study evaluated how the learning curve influences clinical outcomes and overall hospital costs during implementation of RPD.

Why was this study needed?

RPD requires expensive robotic equipment and longer operating times during implementation.

Cost comparisons may be misleading if the robotic learning curve is ignored.

Improved experience could reduce complications, hospitalization, and overall costs.

Real-world economic data from high-volume centers are limited.

Results:

Among 588 patients, RPD initially cost more than OPD but resulted in a shorter hospital stay.

With increasing experience, RPD showed fewer pancreatic fistulas and delayed gastric emptying, shorter operating time, and reduced hospitalization.

RPD costs fell by approximately one-third as experience increased.

After the learning curve, total hospital costs became comparable between robotic and open pancreatoduodenectomy.

Clinical Impact:

The economic disadvantage of robotic pancreatoduodenectomy appears to be largely an implementation and learning-curve phenomenon. In experienced, high-volume centers, improved operative efficiency and postoperative outcomes can offset the higher cost of robotic technology. These findings support structured training and adequate procedural volume when establishing robotic pancreatic surgery programs.

Bottom Line:

Robot-assisted pancreatoduodenectomy is initially more expensive than open surgery, but increasing surgical experience substantially improves outcomes and reduces costs. After the learning curve, RPD can achieve hospital costs comparable with open pancreatoduodenectomy while shortening hospital stay.
