After 3+ years of work, excited to see our @MHEducation @MHMedical textbook on #AI in #surgery available for pre-order!
Written with a non-technical audience in mind & priced to be accessible, we hope this helps introduce topics in #surgicalAI!

🏆 A record $50,000 in prizes @MICCAI_Society

The ORena SAVE FOCUS Challenge is one of MICCAI's 2026 lighthouse challenges

Can #AI track foreign objects across an *entire* operation to prevent retained foreign objects?

#MICCAI2026 #SurgicalAI #MedicalImaging #AIforHealth

[Dan Hashimoto, MD MS FACS @Laparoscopes]

This challenge helps the technical community solve for the problem long term context in a safety critical field - surgery.

For surgeons, this helps unlock AI tools that matter and help solve a never event in surgery - retained foreign objects

This is particularly relevant in light of the Nature papers on multi agent scientific discovery recently published.

It is up to us as a society to determine how we proceed and to shape our futures

Our paper is the 5th most read paper in PNAS Nexus of the last year 🎉.

The article makes a simple point:
Generative AI will produce a socioeconomic earthquake.

Not because all inequalities will increase. This would be too easy.

Some inequalities will increase.
Others will decrease.
And the result is that the socioeconomic landscape will barely be recognizable.

In the information domain, generative AI can democratize content creation and access, but also dramatically expand the production and spread of misinformation.

In the workplace, it can boost productivity and create new jobs, but the benefits will likely be distributed very unevenly.

In education, it can enable personalized learning, but also widen the digital divide.

In healthcare, it can improve diagnostics and accessibility, but also deepen pre-existing inequalities.

This is why we need to stop asking only whether AI is "good" or "bad".

The real question is:
For whom?
In which domain?
Under which institutional conditions?

Recent work led by @WeiqiuYou at the intersection of VLM reasoning and the surgical problem of identifying the critical-view-of-safety!

A fun (and eye-opening) collaboration with @Laparoscopes for explainable AI in surgery problems.

[Dan Hashimoto, MD MS FACS @Laparoscopes]

Great work by @WeiqiuYou as part of her @CIS_Penn PhD dissertation on #XAI!

[PennSurgery @pennsurgery]

New collaborative work b/w @GRASPlab @PCASOLab @Laparoscopes &@CIS_Penn @RICEric22 shows how #XAI methods for structured reasoning improves large VLM performance in identifying CVS anatomy in lap chole

US nonprofit hospitals spent $7.8 billion on management consultants from 2009 to 2023, but contracts were not associated with meaningful changes in finance, operations, or quality of care. 🧵

[Jitendra MALIK @JitendraMalikCV]

I see every week on X an announcement or demo which implies that robotic manipulation has been solved. The only reason I don't believe it is because manipulation had already been solved last week by somebody else! So may I propose the "5 year old paired comparison test" ? At the next conference let's set up a number of tables to which you can bring your robot hardware. Next to it we will have another table where there will be a 5 year old child. In parallel we will try 100 different manipulation tasks that a neutral person has chosen- we could start with "pick up anything" - only household objects (e.g. as might be found in a typical American home) will be used, and we compare the performance of your robot with that of the 5 year old. Can you pick up a coin? Or a book? Or untwist a bottle top? Or insert any plug into a matching socket? Rotate one face of a Rubik's cube? Until your robot can do all the "open world manipulation" that a 5 year old kid can, some humility is in order.

It turns out that when people that were at the top of the class, and were required to endure extreme self-sacrifice for 15+ years, and start their first real job at age 35, that they do in fact want to be able to live in the nice neighborhood along with the corporate types.

New insights on #ChronicAbdominalPain after #RouxEnY gastric bypass!
The latest review by Maria S. Altieri, MD (@altierim1) & coauthors highlights key causes like marginal ulcers, hernias, bile reflux, SIBO & more. 
This work also emphasizes a systematic approach to diagnosis & treatment.
