From robot vs lap surgery and anatomical vs non-anatomical resection to margin width, bile leakage risk, and transplantation—excellent presentations on key issues👏🏼

Our study on robotic liver surgery has been published in the Journal of the American College of Surgeons. 🎉

In this international multicenter study including 1,497 patients from 24 centers, we evaluated whether the Southampton Difficulty Scoring System, originally developed for laparoscopic liver surgery, can be applied to robotic liver surgery.

🔍 Key finding
The Southampton score was associated with increasing perioperative complexity, but showed limited performance in predicting intraoperative complications in the robotic setting (AUC 0.571).

In other words, it can help identify more complex cases, but does not provide sufficiently accurate risk prediction for robotic liver surgery.

We therefore developed the International RoboLiver Difficulty Scoring System, a dedicated model for robotic liver surgery.

RoboLiver included factors such as:
• neoadjuvant chemotherapy
• lesion size >50 mm
• resection type
• previous extrahepatic surgery
• multiple lesions
• bilobar disease

��� RoboLiver uses prolonged operative time as a surrogate for surgical complexity

Higher RoboLiver categories were also associated with increased blood loss, conversion, Pringle use, operative time, length of stay, readmission, and severe morbidity.

These findings highlight the need for robot-specific tools to support preoperative complexity stratification, case selection, and operative planning as robotic liver surgery continues to expand worldwide. 🤖

A special thanks to Mohammad Abu Hilal, senior author and my direct supervisor, who played a central role in shaping this project, Gabriela Pilz da Cunha, shared first author and close collaborator throughout the project, with whom I worked on this study from start to finish, Dr. Rutger-Jan Swijnenburg, shared senior author, for his support and critical input, and Susan van Dieren for her valuable support with the statistical analysis.

Finally, thanks to all co-authors and participating international centers. This work reflects true global collaboration in advancing robotic liver surgery. 🌍

New research shows existing difficulty scores don't work well for robotic liver surgery.

Researchers created a new tool (International RoboLiver Score) to better predict challenging cases, plan operations, and counsel patients more accurately.
