Chair in Bariatric and Metabolic Surgery

Optimize, improve and develop therapeutic intervention methods

The Research Chair in Bariatric and Metabolic Surgery exists to reduce the significant gap between clinical and scientific knowledge. Working closely with the bariatric surgeons of the Quebec Heart and Lung Institute (Institut universitaire de cardiologie et de pneumologie de Québec - IUCPQ),they have developed an exceptional expertise.

The prevalence of obesity is high in many countries and is a major concern for the scientific and medical community. Currently, the only effective treatment against severe obesity is bariatric surgery, which leads to significant and lasting weight loss. The biliopancreatic diversion with duodenal switch procedure involves a reduction in the size of the stomach and reorganization of the small intestine, simultaneously causing a feeling of early satiety and malabsorption of the food ingested.

This Chair is a joint faculty position with the Faculty of Medicine at Université Laval.

The objectives of the Research Chair in Bariatric and Metabolic Surgery are:

  • To build on pre-existing clinical data from patients who have been treated and monitored by the bariatric surgery team at the Quebec Heart and Lung Institute.
  • To identify the predictive physiological factors and biomarkers of the surgery's result.
  • To document and monitor the nutritional state of patients undergoing bariatric surgery at the Institute.
  • To concentrate on the long waiting list for bariatric surgery at the Institute and identify research fields in order to better understand the physiology and state of health of obese patients.
