Meet Dr. Chiasson

Dr. Patrick Chiasson is a Canadian trained Bariatric Surgeon. He has certification from both the Royal College of Surgeons in Canada and the American Board of Surgery in the United States. He received his medical education at McGill University in Montreal, PQ, a Master’s degree from the Institute for the History of Medicine at the Johns Hopkins University in Baltimore, MD, and his general surgical training at Dalhousie University in Halifax, NS. Finally, he completed his sub-specialty training in advanced laparoscopic surgery at the University of Toronto’s highly regarded Center for Minimally Invasive Surgery. He has numerous publications to his credit that address such issues as Minimally Invasive Surgery techniques and outcomes, Health Policy, Medical Ethics and Health Law.

Dr. Chiasson is recognized in the Tuscon, AZ community for his Bariatric Surgery practice. He performs all of the established primary weight loss surgical procedures including: Endoscopic Oberra Intra-Gastric Balloon, Vertical Sleeve Gastrectomy, Gastric Bypass, and the Single Anastomosis Duodenal Switch with Sleeve procedure. In addition, he has a special interest in Revision Bariatric Surgery. He performs Endoscopic and Laparoscopic Revision Bariatric Surgery procedures for both inadequate weight loss and weight regain after primary weight loss surgery. Finally, he offers Bariatric Surgery consultations and surgical management for patients with Bariatric Surgery complications. He is a Bariatric Surgery educational consultant for Ethicon Endo-surgery and is a past president of the AZ chapter of the American Society for Metabolic and Bariatric Surgery.

Dr. Chiasson strongly believes that Bariatric Surgery will continue to evolve with the development of new techniques and new technology with the goal of greatly reducing or eliminating the trauma related to surgery. Moreover, as we expand our mission to treat more than obesity and become the primary treatment option for obese patients with Cardiovascular Disease, Diabetes, NASH syndrome, severe Osteoarthritis, and certain types of cancer, it is his hope that patients come away from their surgical experience feeling that they have received “cutting edge” surgical care within the context of a compassionate, patient focused surgical practice.

His bariatric surgery practice encompasses primary and revision weight loss surgery procedures. These include:

Primary Surgical Weight Loss Procedures:

  • Vertical sleeve gastrectomy
  • Laparoscopic gastric bypass (proximal and distal)
  • Duodenal switch
  • Intragastric balloon

Revision Surgical Weight Loss Procedures:

  • Gastric band to vertical sleeve gastrectomy
  • Gastric band to gastric bypass
  • Gastric band to duodenal switch

In addition, he offers these treatments for severe GERD following vertical sleeve gastrectomy:

  • Magnetic augmentation of the lower esophageal sphincter (LES)
  • Vertical sleeve gastrectomy to gastric bypass
