Presentation Overview

Bariatric surgery remains the most effective tools to assist in weight loss and improvements in cardiometabolic health. Recent consensus guidelines have relaxed eligibility criteria for surgery in adolescents, but there remains a paucity of long term data regarding sustained weight loss and predictors of who will benefit most from these procedures in this age group.  Recent guidelines will be highlighted, and local data from the SickKids Team Obesity Management Program (STOMP) will be presented, with a focus on predictors related to weight loss 1-2 years after surgery.

Learning Objectives

She facilitates workshops for professionals and presents at research conferences. Dr. Wnuk is an Assistant Professor at the University of Toronto Department of Psychiatry.

Presentation Overview

Problematic postoperative eating behaviors can impact weight loss outcomes, mental health and quality of life. These include loss of control over eating, grazing, overeating, emotional eating, night eating, overly restrictive eating and purging. Associated emotional and cognitive features include over-evaluation of weight and shape, preoccupation with weight loss, hopelessness, shame and body image distress. These symptoms may have existed prior to surgery or may develop for the first time post-bariatric surgery. They should be identified and addressed as they may be indicators for weight regain and the re-emergence of associated medical comorbidities, mobility limitations, and mental health distress.  However, assessing eating-related psychopathology following bariatric surgery can be complex, given the expected surgical and behavioural consequences of bariatric surgery.  For example, following surgery patients may experience frequent vomiting and food intolerances, and may be instructed by clinicians to eat slowly and measure portions, symptoms and behaviours that overlap with eating disorder presentations. By better understanding these shared features, as well as the symptoms that are unique to eating disorders, bariatric clinicians can learn to screen for eating psychopathology and provide appropriate psychoeducation and referrals for more comprehensive assessment and treatment. 

Learning Objectives

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

  • Understand how eating psychopathology presents following bariatric surgery
  • Know how to screen for eating disorder symptoms
  • Consider a triage plan for patients with significant eating psychopathology

Presentation Overview 

A short-term pre-operative energy restrictive diet to facilitate Bariatric surgery intervention by: reducing liver size, improving liver tissue flexibility during surgery, ensuring access to the esophageal junction, and preventing laceration of liver. Such preparations help to reduce bariatric surgery cancellation rate and possibly post-operative complications, as the liver tissue burden on the surgical site is attenuated 

No consensus on the preoperative bariatric diet on total caloric daily intake or classification of types of macronutrients consumed by patients. The use of low calorie diets resulted in a mean liver size reduction of 9-18%. Duration of diet has been reported to vary between 1-6 weeks, and for most current pre-operative diets there are neither objective measures of liver size reduction nor randomized study designs to evaluate success. In Ontario alone, 13 Weight Management centres (including major hospitals for their pre-operative diet before bariatric surgery) offer Optifast (https://www.optifast.com/Pages/ca/index.aspx).

From discussions at national gatherings of bariatric programs it is likely that Optifast is currently the most common pre-operative diet in Canadian bariatric centers. This is an observational and descriptive prospective study which has compared two pre-operative diets, Optifast and RMBS, in terms of: liver volume reduction, liver enzymes, patient recruitment and satisfaction, and clinical anthropometric indices in patients who are set to undergo a bariatric surgery procedure.

Learning Objectives

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

  • Understand the reason behind a preoperative diet prior to bariatric surgery,
  • Explain the differences between common liquid diet and scientifically designed solid diet,
  • Recognize newly designed solid diet for patients prior to the bariatric surgery or any abdominal surgery.

Presentation Overview

The concept of post addiction transfer after surgery has been discussed with regard to bariatric patients.  One topic of interest has been the increased use of alcohol post operatively. As a result, a focus of pre-operative assessment has been to consider substance use and the risk of use after surgery. This presentation will explore post addiction transfer specific to alcohol use, contributing factors, as well as the impact on post-opertaive well-being from a psychological and psychosocial perspective. 

Learning Objectives

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

Presentation Overview

The increased risk for medical and psychosocial comorbidities affecting the quality of life of individuals living with obesity is well established within the literature. Sexuality and intimacy, however, is a frequently overlooked aspect of quality of life in both research studies and clinical care. This presentation will focus on the Sexual Quality of Life and functioning of individuals with obesity, the unique changes in these domains subsequent to bariatric surgery, and the role health care practitioners can play in providing patients with the support they need (and may be too afraid to ask for). 

Learning Objectives

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

  • Understand the importance of sexuality and intimacy for overall quality of life
  • Understand the ways sexuality and intimacy can be impacted by obesity and bariatric surgery
  • Understand the role that healthcare practitioners can/should play in addressing patient concerns related to Sexual Quality of Life

Ms. Millard’s clinical interests include body image, addiction transference, weight regain, and weight acceptance. 

Presentation Overview

Peer support groups have been known to be beneficial across many healthcare treatment programs. The post-operative period for bariatric patients can be challenging given the long term lifestyle changes required. Although follow up is provided by healthcare professionals patients benefit from peer support specifically due to the share experience of surgery. This presentation will explore the advantages of having peer support, topics that are discussed in peer support and tricky issues to navigate when facilitating peer support groups.  

Learning Objectives

  • To explore the advantages of having peer support.
  • Have an awareness of topics and themes of interest to post-operative bariatric patients.
  • To understand the tricky issues to navigate when facilitating peer support groups specific to bariatric surgery
17:00 - 17:20 Weight Acceptance and Expectations
Speaker: Ms. Tanya Costantini
Details

Tanya Costantini, MSW, RSW, CDE 
Social Worker and Certified Diabetes Educator 
Guelph General Hospital, Bariatrics
Guelph, Ontario

Tanya Costantini  is a registered Social Worker in the Surgical Bariatric Clinic at Guelph 
General Hospital.  As a Certified Diabetes Educator, she has a passion for working with 
individuals with chronic diseases, showcased by her work with her patients in the 
bariatric program. In the last year, Tanya has co-facilitated a pilot Mindfulness-Based Cognitive Therapy group specifically for bariatric patients. The MBCT group helped patients increase their awareness of both emotional and physiological cues, as well as develop healthy coping skills and improve self-acceptance. In the community, she has also facilitated the program Craving Change™, which embraces a cognitive behavioural approach to help patients change their relationship with food. She is also an active member within her community and hopes to continue to use her CDE designation to increase the awareness of the overwhelming psychosocial impact of diabetes.

Presentation Overview

Every patient comes into a bariatric surgery program with a different expectation they are hoping to achieve post-surgery. Often times, with obese patients, these expectations are extrinsically motivated and unrealistic. This presentation will explore how unrealistic weight loss expectations can affect patients’ sense of self and our role as clinicians in helping patients set realistic expectations. To help patients develop realistic weight expectations, weight acceptance is key. Weight acceptance leads to both physiological and psychological benefits. This presentation will discuss how we can help bariatric surgery patients develop weight acceptance by shifting how they relate to themselves and helping them tune in to their bodies. 

Learning Objectives

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

  • Define weight expectations and weight acceptance 
  • Explain how unrealistic weight expectations affect patient success
  • Identify the benefits of weight acceptance
  • Demonstrate how to support patients in developing weight acceptance
