Meet the Director of UCSD's Center for the Treatment of Obesity

Dr. Santiago Horgan, Director of Minimally Invasive Surgery at UC San Diego Medical Center, is an internationally recognized expert in robot-assisted surgery and other minimally invasive surgical techniques.Santiago Horgan

Dr. Horgan was among the first surgeons trained to perform the Lap-Band Adjustable Gastric Banding System procedure used for the treatment of obesity. He was instrumental in bringing gastric banding to the United States, and is one of just 20 surgeons in the country who participated in the FDA clinical trial leading the approval of the LAP-BAND® Adjustable Gastric Banding System for the treatment of morbidly obese patients.

As the director of UCSD’s Center for the Treatment of Obesity, he has performed more than 1,000 Lap-Band procedures and instructs other surgeons in the Lap-Band and Realize Band techniques throughout the United States.

In addition, Dr. Horgan performs other weight loss surgeries including:

  • gastric sleeve
  • gastric bypass
  • gastric banding with the Realize band

A specialist in minimally invasive surgical techniques, Dr. Horgan is skilled in the use of the da Vinci robot system, which enables surgeons to perform even the most complex and delicate procedures through very small incisions with unmatched precision.

Dr. Horgan is also a pioneer in the emerging field of Natural Orifice Translumenal Surgery (NOTES), in which surgical instruments are passed through a natural orifice such as the mouth to reach the desired organ. By avoiding major incisions, the NOTES procedure can provide patients with a faster recovery time and virtually no scarring.

As the director of UCSD’s Center for the Future of Surgery, Dr. Horgan is working with colleagues to advance these scarless techniques by investigating, developing, testing, and teaching procedures that will revolutionize the field of surgery. To date, he has performed more than a dozen NOTES procedures and is involved in continuing clinical trials.

Before he joined the UCSD Department of Surgery as Professor of Clinical Surgery in 2006, Dr. Horgan was Director of the Minimally Invasive Surgery and Robotic Surgery Department and Co-Director of the Swallowing Center at the University of Illinois at Chicago. He was also Director of the Minimally Invasive Bariatric Center in Chicago.

  • In 2005, Dr. Horgan was named one of America’s Top Doctors by Castle Connolly Medical Ltd.

Dr. Horgan and his team understand the challenges of weight loss and the vital importance of a supportive atmosphere. He tells each of his patients: “We’re going to teach you, coach you, and help you through the whole process.”
