An Exploration of the Patient Lived Experience of Remission and Relapse of Type 2 Diabetes Following Bariatric Surgery.

BACKGROUND: Bariatric surgery is the most effective treatment for patients with obesity and type 2 diabetes (T2DM), inducing profound metabolic changes associated with improvements in glycaemic control. In spite of the recognition of the physiological changes associated with bariatric surgery, what remains underappreciated is the patient experience of surgery to treat T2DM. OBJECTIVES: This study explored the patient experience with regard to motivations, expectations and outcomes, including remission and relapse of diabetes. METHODS: An in-depth qualitative approach was adopted, encompassing semi-structured interviews with patients (n=17) living with obesity and T2DM both pre- and postsurgery. Interpretive thematic analysis identified emergent themes using a grounded approach. RESULTS: Analysis revealed a number of themes throughout the interviews which included motivations and perceived benefits of surgery, obesity stigma and its impact on self-worth as well as perceptions of remission or relapse and the implications for sense of control. CONCLUSIONS: The motivation for undergoing bariatric surgery was driven by health concerns, namely T2DM and the desire to reduce the risk of developing diabetes-related complications. Patients highlighted social and self-stigmatisation associated with obesity and T2DM, leading to feelings of shame and an inability to seek support from family or healthcare professionals. Stigmatisation created a sense of failure and feeling of guilt for having T2DM. As a result, patients felt responsible for maintaining disease remission postoperatively and regarded the need for medication as a sign of treatment failure.

The role of staging laparoscopy in complex bariatric surgery.

Determining which patients will benefit from bariatric surgery is complex; however, in those who have had previous bariatric surgery or extensive abdominal surgery, this can be particularly challenging. Decisions are often made based on assumptions rather than a complete assessment of all the anatomical and physiological factors. Adopting the approach utilised in gastrointestinal surgery with a diagnostic or staging laparoscopy, it may be possible to more accurately stage disease and determine fitness bariatric surgery. Laparoscopy is relatively low risk and contributes critical information with regard to access, post-operative anatomical changes and response to anaesthetic. Additionally, it allows surgeons to accurately determine the feasibility of undertaking a procedure and facilitates a more precise discussion with patients regarding suitability for surgery. Denying patients bariatric procedures based on an incomplete assessment of risk is unfair. Scenarios in which patients have had previous surgery, particularly bariatric surgery are increasingly common with the numbers requiring revisional surgery steadily rising. Although only applicable in highly selected, very complex cases, diagnostic laparoscopy adds critical information in the preoperative assessment of patients, not only improving care but potentially widening the numbers considered eligible for bariatric surgery. Our limited experience with staging laparoscopy in patients with previous complex abdominal surgery requiring revisional surgery illustrates the potential benefit it offers in determining patient suitability for further bariatric procedures. The adoption of an established technique, applied in a novel setting offers surgeons the opportunity to more thoroughly assess potentially high risk patients as well as the ability to offer personalised care.

Long-term outcomes of bariatric surgery in patients with diabetes.

Introduction: Initially seen as a weight-loss operation, bariatric surgery is now recognized as a metabolic procedure with a critical role in the management of type 2 diabetes mellitus (T2DM). Early improvement in glucose metabolism is a remarkable effect of surgery; however, what deserves equal thought are implications for long-term diabetes control and relapse. Evidence suggests the metabolic effects of surgery fatigue and a proportion of patients will experience relapse of T2DM, with or without weight regain. Herein, we discuss the evidence examining the durability of these effects and approaches to improve long-term control.Areas covered: PubMed, Embase, CENTRAL, and Medline were searched for trials looking at outcomes for patients with obesity and T2DM undergoing bariatric surgery between January 2000 andDecember 2019. Additional studies were found by searching publications from related journals and references.Export opinion: Bariatric surgery is a safe and effective treatment for T2DM and obesity however the response to surgery, like any other treatment is variable. Some patients will experience a relapse of diabetes in the long term. Recent developments in pharmacotherapy present an opportunity to augment or sustain what can be achieved with surgery. Combinational treatment may dramatically change the way both diseases are managed.
