Better mapping of small-calibre blood vessels could advance our understanding of tissue perfusion & anastomotic healing

🕊️ In Memoriam

It is with profound sadness that we learned of the passing of Prof. Dr. Angelita Habr-Gama, one of the most influential figures in colorectal surgery and a pioneer whose innovative contributions transformed the treatment of rectal cancer worldwide.

Throughout her distinguished career, Prof. Dr. Habr-Gama inspired generations of surgeons and researchers through her dedication to science, education, and patient care. Her pioneering work, particularly in the development of the “watch and wait” approach for rectal cancer, has left a lasting impact on modern surgical practice.

We extend our deepest condolences to her family, colleagues, students, and the global colorectal surgery community.

Her legacy and contributions to medicine will continue to inspire future generations.

Prof. Angelita Habr-Gama was a true titan of surgical oncology.
By pioneering the "Watch and Wait" approach, she single-handedly challenged established dogma, transformed rectal cancer treatment, and spared countless patients around the world from life-altering surgery. Her immense courage, clinical brilliance, and deep humanity completely redefined organ-preserving care.
The global colorectal community has lost a monumental figure, but her legacy will live on in every surgeon she inspired and every patient touched by her vision.
May she rest in peace.

Prof. Angelita Habr-Gama was an absolute titan. It is hard to overstate the profound impact she had on surgical oncology.
Before her pioneering work on the "Watch and Wait" approach, radical, life-altering surgery was the unquestioned standard for rectal cancer. It took immense courage, clinical brilliance, and fierce determination to challenge the established dogma of the time. Because she stood her ground and proved what was possible, countless patients worldwide were spared major surgery and given a vastly better quality of life.
She didn't just change guidelines; she changed the very philosophy of how we approach rectal cancer treatment, blending rigorous science with deep humanity.
As the global colorectal community—including the @TKRCD_ , @ASCRS_1, @escp_tweets @ISUCRS1 @ACPGBI, and @PortalSBCP mourns her passing, her legacy remains alive in every multidisciplinary team discussion, every organ-preserving protocol, and every young surgeon inspired by her pathbreaking career.
A truly monumental loss, but an enduring legacy. May she rest in peace.

Very proud to see this student-led project from Ankara University published in Surgery.

Special congratulations to my colleague Dr. Utku Çelik (@s_utkucelik), who led this work with great dedication and vision. It has been a real pleasure to contribute to and support this journey together with such an enthusiastic young team.

Our national survey among general surgeons explored the current knowledge, utilization, expectations, and concerns regarding AI in surgery. The study highlights both the excitement surrounding AI and the need for structured education, ethical frameworks, and responsible integration into surgical practice.

The future of surgery will be shaped not only by technology, but also by the young physicians and students who are willing to question, produce, and lead.

It’s IBD week.
In IBD, the hard question is rarely only “what”.
It is “when”.

When to escalate.
When to operate.
When to wait.
When to protect bowel, fertility, function and quality of life.

Prehabilitation improves recovery and reduces complications for patients undergoing colorectal surgery, yet generalizability and feasibility depend on program adherence and addressing patient-centered psychosocial outcomes. https://t.co/g5mvBm9v3F

Perianal Crohn’s Disease Destination: Seton vs. Repair

Management of perianal Crohn’s disease remains one of the most difficult and frustrating challenges for both patients and providers. How do you balance a patient’s desire for a “cure” with the chronic nature of the disease, the high likelihood of re-intervention, and the need to preserve continence?

Join us for a thoughtful, evidence-driven debate as Professors de Buck van Overstraten and Bemelman examine destination seton versus repair of Crohn’s fistulas, exploring the tradeoffs, long-term considerations, and evolving strategies behind each approach.

After rectal cancer, Transanal irrigation (TAI) significantly improved
✅ Quality of life
✅ Bowel function
✅ Fecal incontinence

Better bowels, better lives!

TAI changes survivorship 💪
