Presentation Overview:

The Duodenal Switch (DS) accounts for less than 5% of bariatric surgeries performed in Canada. Though it is one of the most efficient bariatric surgeries for long term weight loss and remission of comorbidities, the significant malabsorption associated with DS can induce metabolic consequences on peripheral and central nervous system and can increase the risk of nephrolithiasis. 

Learning Objectives:

At the end of this presentation, participants will be able to:

  1. Understand the pathophysiology of the development of kidney stones after bariatric surgery
  2. Manage patients with nephrolithiasis after malabsorptive surgery to decrease recurrence of kidney stones.
  3. Understand the impact of nutritional deficiencies on central and peripheral nervous system.
  4. Assess and treat patients who have neurologic complications related to bariatric surgery

Presentation Overview:

Bariatric surgery has been used as an effective tool, in combination with life style changes, to provide long term weight-loss, improve/resolve coexisting diseases and overall help improve quality of life. Like many other treatments, it may involve complications one of which is reactive hypoglycemia (non-insulinoma pancreatogenous hypoglycemia syndrome) which is a rare and potentially serious complication post gastric bypass (RYGB). The purpose of this study was to review a severe case of hypoglycemia post sleeve gastrectomy (SG) and how it was treated by collaboration between our endocrinologist, registered dietitian, and registered nurse.

Learning Objectives:

At the end of this presentation, participants should be able to: 1) define non-insulinoma pancreatogenous hypoglycemia syndrome, 2) understand tests commonly used to diagnose this condition, 3) apply therapeutic methods to treat it, and 4) realize how collaboration of health care team can benefit the patient.

Research interests include: understanding the psychological and behavioral factors associated with chronic diseases (i.e., obesity, asthma, cardiovascular diseases) and behavioral interventions for chronic disease patients. Her doctoral thesis consists of the development of an adjunct behavioral intervention to improve long-term weight management in patients undergoing bariatric surgery.

Presentation Overview:

Obesity, particularly morbid obesity, is associated with psychological stress and problematic eating. However, there is inconsistent evidence about potential psychological and behavioral contributors to preoperative weight outcomes in bariatric populations. This presentation will look at the associations between weight, depression and problematic eating behaviours in a sample of candidates for bariatric surgery from the Canadian REBORN cohort. Depressive status and eating behaviours may not significantly impact pre-bariatric surgery weight and weight changes. However, depression may increase problematic eating in bariatric patients, which suggests a role for depression in suboptimal postoperative weight outcomes in this population.

Learning Objectives:

At the end of this presentation, participants will be able to:

  1. Determine whether depression and/or problematic eating behaviors influence weight and BMI changes in obese patients before bariatric surgery.
  2. Describe the associations between depression and problematic eating patterns in candidates for bariatric surgery.
  3. Recognize the potential benefit of targeting depression to improve postoperative outcomes in patients undergoing bariatric surgery.

Avril Gagnon-Chauvin completed her Bachelor degree in psychology at Université de Montréal in 2016. She is currently doing her Ph.D in psychology, at Université du Québec à Montréal. Her main research interests are in the fields of behavioral medicine and health psychology. She is particularly interested in the influence of psychological disorders on the development and the retention of chronic diseases such as asthma, cardiovascular diseases and obesity. She also has an interest in the promotion of healthy behaviors to reduce chronic diseases’ morbidity.  Ms. Gagnon-Chauvin’s thesis addresses prevalence and impacts of psychological disorders on surgery outcomes in bariatric surgery candidates. 

Presentation Overview:

This research aimed to assess the prevalence of psychological distress among bariatric surgery candidates and to determine the association between preoperative psychological distress and quality of life. Pre-bariatric surgery patients completed self-reported questionnaires assessing depression and anxiety symptoms and health quality of life on the day of their preoperative visit. Findings suggest that the prevalence of psychological distress is high among bariatric surgery candidates. Moreover, severe depressive symptoms are related to poorer mental health quality of life, whereas severe anxiety symptoms are related to worse physical health quality of life. 

Learning Objectives:

At the end of this presentation, participants should be able to better understand the psychological profile of bariatric surgery candidates.

They should also be able to better understand the impact of depression and anxiety symptoms on physical and mental health quality of life before surgery.

As well, the participants will be brought to consider the importance of addressing psychological distress in bariatric surgery candidates.
