Buenos Aires hosts landmark neuroendoscopy congress showcasing minimally invasive brain surgery advances

Buenos Aires became the unexpected center of a quiet revolution in brain surgery this May. For three days, more than 150 neurosurgeons from around the world gathered at the NH Hotel to discuss how to operate on the human brain with less cutting, less risk, and more precision than ever before. The occasion was the first International Congress of Neuroendoscopy—IFNE + GLEN—ever held in Argentina, a milestone that signaled something larger: that this country had moved from observer to player in one of medicine's most demanding frontiers.

The congress, organized by the Garrahan Foundation in partnership with the International Federation of Neuroendoscopy and the Latin American Neuroendoscopy Study Group, drew an audience of 300 people and showcased innovations that would have seemed like science fiction a decade ago. Surgeons presented techniques for reaching tumors buried deep in the brain—in the pineal gland, for instance, a region so remote and delicate that traditional open surgery carried enormous risk. They demonstrated how 3D-printed models, virtual reality platforms, and robotic systems were changing the way young surgeons learned their craft, allowing them to practice complex maneuvers in a simulator before ever touching a patient's skull. They unveiled real-time imaging tools that could identify tumor tissue during surgery and molecular analysis systems that could guide treatment decisions in the operating room itself.

One of the congress's central themes was how technology was democratizing access to safer surgery. Dr. Carlos Brusius from Brazil presented a training system that combined 3D models, virtual reality, and high-fidelity simulators to teach neuroendoscopic procedures. The logic was straightforward: if surgeons could practice difficult moves in a risk-free environment, they would make fewer mistakes when it mattered. Dr. Joachim Oertel, a renowned German neurosurgeon, walked through how modern endoscopic techniques allowed surgeons to navigate to deep brain lesions with millimetric precision, reducing damage to surrounding tissue and shortening recovery time. For patients, this meant less trauma, fewer complications, and faster healing.

The robotics presentations pointed toward an even more distant horizon. Dr. Bassel Zebian from Britain and Dr. Jun Muto from Japan described systems that could plan and execute brain surgery with unprecedented accuracy, guided by artificial intelligence that analyzed data in real time and assisted surgeons in decision-making. These tools were not replacing surgeons—they were extending their capabilities, allowing them to attempt procedures that would have been too risky or technically impossible just years before.

Perhaps the most human dimension of the congress emerged in discussions of pediatric cases. Dr. Samer Elbabaa from the United States presented an alternative to traditional shunt surgery for children born with hydrocephalus and spina bifida. Instead of implanting permanent devices that often required repeated surgeries and carried infection risk, surgeons could now use endoscopic techniques to restore normal cerebrospinal fluid flow. For families, this meant fewer operations during childhood, fewer hospitalizations, and a better quality of life. The cost savings to health systems were significant, but the real measure was simpler: fewer children spending their childhood in and out of operating rooms.

Dr. Sebastián Jaimovich, who chaired the congress, emphasized what the gathering represented. Argentina, he said, was positioning itself at the forefront of international neurosurgery. The decision to hold the congress in Buenos Aires was not ceremonial—it reflected genuine expertise and innovation happening in Argentine hospitals and research centers. Dr. Javier González Ramos, the scientific director, called it one of the most important international events in the field, a moment when a country demonstrated its capacity to convene world leaders and showcase its own potential.

What emerged across three days of presentations was a portrait of a specialty in transformation. The tools were changing—robotics, artificial intelligence, real-time imaging. The training methods were changing—from apprenticeship in the operating room to practice in virtual space. The outcomes were changing too: surgeries that were once considered too dangerous were becoming routine, and patients who would have faced permanent disability or repeated interventions now had alternatives. Argentina's role in hosting this congress, and in contributing innovations of its own, suggested that this transformation was not happening in isolation in a few elite centers in Europe and North America. It was becoming global, and it was reaching places where it could help children and adults who had few options before.
