Surgeons at the Hospital Clínico San Borja Arriarán performed their first endoscopic breast surgery on September 2, 2026, marking the launch of a new minimally invasive program at the facility's Breast Pathology Unit.
Clinical Approach and Technique
According to Dr. Del Río, the technique utilizes endoscopic vision through a single lateral incision situated in the armpit line. Surgeons extract the breast tissue and perform immediate reconstruction through the same pathway. While the surgical access and technology differ from traditional methods, Dr. Del Río stated that the oncological procedure remains identical to standard open surgery.
Oncological Safety and International Evidence
Medical literature demonstrates that endoscopic breast procedures yield oncological outcomes equivalent to open surgery. According to Dr. Del Río, international studies encompassing over 2,500 patients indicate that the technique does not elevate the risk of local recurrence, metastasis, or cancer mortality when performed on suitably selected patients. Furthermore, the approach avoids visible scarring on the breast while preserving blood supply to the nipple-areola complex more effectively than conventional operations, thereby lowering necrosis risks.
Patient Selection and Preparation
During the initial phase of the program, the technique targets carefully chosen patients. According to the hospital’s clinical team, candidates include women with early-stage breast cancer requiring mastectomies, as well as individuals with genetic mutations who face exceptionally high lifetime risks and require risk-reducing mastectomies. Patient selection relies on tumor characteristics and individual patient anatomy.
To prepare for the rollout, the surgical team completed a progressive implementation program. According to the university, this preparation involved training in laparoscopic surgery, simulation practice with anatomical models, and participation in the first cadaveric course for endoscopic mastectomy held at the Cleveland Clinic in the United States. The training encompassed surgeons, anesthetists, nurses, midwives, and surgical instrument specialists.
Institutional Significance
According to Dr. Altamirano, conducting the procedure within a university training center demonstrates the integration of advanced surgical technologies and highlights the faculty's commitment to medical innovation, specialist training, and patient care enhancement.
