Surgical planning: anticipating anatomical variations with the digital twin

Dr. Rahal's story, 50 years old

I am a digestive surgeon. During a colon cancer surgery, I discovered an unexpected vascular anatomical variation. Nothing insurmountable, but it extended the operating time. Readapting the surgical approach in real time demands extreme vigilance. Everything turned out well, fortunately. But it reinforced my conviction in the value of advanced pre-operative 3D simulations. Anticipating these singularities changes both mental and technical preparation. An enriched digital twin would clearly have been a valuable support.

How MyTwin can help

This testimony highlights a central issue in surgical planning: the anticipation of individual anatomical variations.

Even in standardized procedures, certain vascular or structural singularities can appear intraoperatively, requiring immediate adaptation of the surgical approach, with potential impact on operating time, technical complexity and the team's cognitive load.

In this context, MyTwin provides a response based on personalized anatomical modeling.

The platform allows, through specialized partner applications, to reconstruct pre-operative 3D models from the patient's imaging data (CT scan, MRI, etc.), in order to create an enriched digital representation of individual anatomy.

MyTwin can help to:

  • Visualize the patient's specific anatomical structures
  • Identify potential vascular or morphological variations
  • Simulate different surgical scenarios in advance
  • Optimize technical and strategic preparation of the procedure
  • Support the mental preparation of surgical teams

The objective is to strengthen pre-operative anticipation through an immersive and personalized view of anatomy, complementing existing planning tools.
