Psychosocial presentation of revisional LAGB patients: a qualitative study

Dietary experiences after bariatric surgery in patients with obesity: A qualitative systematic review

This systematic review evaluated the dietary experience of patients with obesity post-bariatric surgery. Scopus, CINAHL, Medline, Psych INFO, and Embase databases were searched and JBI Critical Appraisal Tool was used for quality assessment. Thomas and Harden's three-stage thematic synthesis was undertaken using the Enhancing transparency in reporting the synthesis of qualitative research (ENTREQ) statement for reporting. Of the 24 studies extracted, we coded and developed 34 descriptive themes into 7 categories, which were then categorized to 3 analytical themes. The number of all the participants in the 24 articles is 383 people. The results revealed most patients can control their diet for a short period post-surgery. However, this was a matter of gradual self-consciousness as patients also required support and dietary management in postoperative recovery. CLINICAL TRIAL REGISTRATION NUMBER: The protocol for this qualitative systematic review has been registered with PROSPERO (registration number CRD42021229083).

Pre-operative Restraint and Post-operative Hunger, Disinhibition and Emotional Eating Predict Weight Loss at 2 Years Post-laparoscopic Adjustable Gastric Banding

INTRODUCTION

A principal mechanism of action in bariatric surgery is reduction in calorie consumption due to decreased hunger and increased satiety. Patients' ability to perceive post-operative changes to their hunger is therefore central to optimal results. This study examined factors that may impact how patients perceive post-operative hunger and how perception of hunger impacts eating and subsequent weight loss after laparoscopic adjustable gastric banding (LAGB).

METHODS

Patients undertaking LAGB (n = 147) provided pre-surgery and 2-year weight loss data and pre-surgery and 12-month psychological data (perception of hunger, disinhibition related to eating, emotional eating).

RESULTS

Path analysis demonstrated that patients with lower levels of pre-surgery cognitive restraint over eating experienced significantly greater reduction in perception of hunger at 12 months post-surgery. Perceived reduction in hunger was significantly associated with lower levels of both emotional eating and disinhibited eating. Finally, reduced emotional eating at 12 months significantly predicted 9% of the variance in percentage of total weight loss (%TWL) at 2 years after surgery.

CONCLUSION

These initial findings suggest that preparation for bariatric surgery may be enhanced by psychoeducation regarding cognitive restraint over eating and its effect on hunger perception. In addition, psychological treatment that focuses on identifying and responding to changes in hunger may contribute to improved outcomes for those who have difficulty adjusting to post-operative eating behaviours.

Psychosocial presentation of female bariatric surgery patients after multiple revisional surgeries: A qualitative study

Bariatric surgery is currently the most viable and cost-effective treatment for obesity. This study aimed to understand, from a female patient’s perspective, what contributed to not achieving or maintaining excess weight loss from a primary laparoscopic adjustable gastric band surgery, leading to subsequent multiple revisional bariatric surgeries. The purposive sample of participants ( N = 17 females) were over 18 years, had a primary failed laparoscopic adjustable gastric band and had more than three revisional procedures. Participants were individually interviewed and data were analysed from a grounded theory methodology to build a causal model with the core category of unrealistic expectations of bariatric surgery and other important conceptual categories.
