Our new publication describes #AI-driven framework aims not only to predict #AnastomoticLeak, but also to improve visualization of the bowel microvasculature 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 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. #SoMe4Surgery #AngelitaHabrGama #ColorectalSurgery #RectalCancer #ColorectalCancer #SurgicalOncology #Coloproctology #GlobalSurgery #WomenInSurgery

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. #ESCP #IBD #colorectalsurgery #CrohnsDisease #UlcerativeColitis

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. ja.ma/3RgB1Mo
