Following his training, Dr. Santos was in practice as a general surgeon at Kaiser Permanente Southern California Medical Group as a high volume clinical surgeon. A desire to pursue a career in academic surgery and apply his extensive clinical experience in acute care surgery and advanced laparoscopy led him to MD Anderson Cancer Center, where he is the section chief of General Surgery.
Dr. Santos has clinical and academic interest in improving the outcome of cancer patients with general surgical issues not directly related to their oncologic disease. Other particular areas of interest include application of advanced robotics abdominal wall reconstruction for hernia repair, splenectomy, complex cholecystectomy, and vascular access for chemotherapy. He is also exploring the relationship between morbid obesity and cancer outcomes.
