In the early days, when we began working on a surgical training development project, our aim was not to redefine anastomosis evaluation. We simply wanted to observe them closely, seeking ways to capture and share the subtle ‘tacit’ knowledge in surgery that’s usually only gained through experience. What started as a technical replication quickly became a powerful tool for understanding and improving surgical performance.
‘I still remember the early days when we set out to develop a method for replicating and analyzing anastomoses. We had just started exploring high-resolution scanning to visualize the vessel lumen in detail,’ recalls Dr. Balazs Gasz, cardiac surgeon and founder of YourAnastomosis.
‘As a cardiac surgeon, I performed saphenous vein end-to-side anastomoses to support the development. For each trial, I chose what I believed was my best work. When we finally applied the most promising method, I gave it everything, confident that the scan would at least be decent.’
said Balazs Gasz, co-founder of YourAnastomosis.
It was like transformative. The model, scanned at 9 micron resolution, revealed subtle flaws in stitch orientation, lumen alignment, suture depth, and details invisible even under magnification.
‘I was shocked. So many imperfections appeared that I almost didn’t want to look. Yet as I reviewed it stitch by stitch, I began to see exactly where I could improve. That moment changed everything. It sparked my dedication to comprehensive anastomosis analysis.’
From exposure to insight
What began as a technical self-assessment evolved into a more advanced approach to anastomosis training. High-resolution lumen reconstruction reveals morphological details, often hidden in visually acceptable work, that may affect clinical outcomes. Subtle deviations like heel narrowing, uneven suture spacing, or twisting can disrupt flow and raise graft failure risk by altering hemodynamics.
By focusing on lumen geometry and internal continuity rather than external appearance, the YourAnastomosis platform links technical execution to both morphological and functional integrity, bridging simulation with physiological relevance to improve graft patency and patient outcomes.
A new standard for feedback and growth
The realization that even experienced surgeons can keep improving, not by relying on guesswork but with clear and measurable feedback, became the foundation of what we built with YourAnastomosis.
Today, surgeons and trainees use the platform to:
- practice on case-specific 3D-printed models based on real surgical anatomy
- receive in-depth analysis, including morphological and CFD assessment, expert review, and scoring
- use AR guidance during key steps of the procedure to support hands-on learning
- follow a personalized training pathway tailored to their skill level and performance
- build a personal performance profile through structured, proficiency-based evaluation
‘These high-fidelity lumen replications are not tools for exposing failure. They are tools for learning, ‘says Dr. Gasz. ‘They reveal subtle, often overlooked details that help us improve. They have helped us better understand anastomosis morphology, function, and recurring error types. And ultimately, all of this serves one goal: improving outcomes for our patients.’
Why this moment still matters
This story is more than a milestone in product development. It reflects how humility, data, and curiosity can reshape surgical education. It shows that even our best efforts have room to improve and that is not a flaw, but a strength.
From 9 micron detail to real-world impact, YourAnastomosis builds on that insight, stitch by stitch.
