Weight loss and self-perceived quality of life following laparoscopic Roux-en-Y gastric bypass: is it important?

Q: What is the main focus of this study after laparoscopic Roux-en-Y gastric bypass?

The study focuses on how the amount of weight loss after LRYGB relates to self-perceived quality of life improvement, assessed using SF-36.

Q: How were participants and follow-up handled in the analysis?

Patients who underwent LRYGB between January 2017 and December 2019 were included, requiring a minimum follow-up of 3 years. A total of 95 individuals were enrolled for the QoL questionnaire.

Q: Which SF-36 QoL domains showed the most and least favorable results?

Physical functioning (D1) scored best, while pain (D3) scored worst in the QoL domain assessment.

Weight loss after metabolic and bariatric surgery is commonly used to judge outcomes and is often linked to self-perceived quality of life (QoL). This study evaluates the association between weight loss following laparoscopic Roux-en-Y gastric bypass (LRYGB) and self-perceived QoL improvement. Medical records of patients treated between January 2017 and December 2019, with at least 3 years follow-up, are compared across %TWL, age, and time since surgery using SF-36. Among 95 individuals, physical functioning scored best and pain worst, with specific QoL domains improving by greater %TWL, older age, and longer postoperative duration.

• Weight loss is an important parameter after metabolic and bariatric surgery, however, non-significant reductions in body weight and comorbidities improvement may already be sufficient to increase the quality of life (QoL) .
• Laparoscopic Roux-en-Y gastric bypass (LRYGB) can have a direct relationship with significant positive impacts on health-related self-perceived QoL, sustained in the long-term.
• Ninety-five individuals previously submitted to LRYGB were enrolled for questionnaire application (SF-36) of QoL. D1 (physical functioning) was the best scoring domain, while D3 (pain) was the worst.
• There was a significant improvement ofthe D4 (general health) domain in patients with %TWL (Total Weight Loss) greater than 30%(p<0.05), D7 (role emotional) and D8 (mental health) domains in patients older than 45 years (p<0.05) and better results in D7 (role emotional) domain in patients over 5 years after surgery (p<0.05 |

CENTRAL MESSAGE Weight loss (WL) is the most commonly used datum to measure the results of metabolic and bariatric surgery. The amount ofWL is generally directly and proportionally associated with the improvement in quality of life (QoL), as the greater the former, the greater the perception of well-being. However, improvements in QoL may also not belinearly related to the amount of weight lost, as nonsignificant reductions in body weight may already be sufficient to increase QoL in physiological, psychological, social, and economic aspects. Furthermore, QoL seems to be one of the main targets of patients seeking bariatric procedures, which is not always properly valued. PERSPECTIVES In the present study, we demonstrate that the amount of weight lost provided by laparoscopic Roux-en-Y gastric bypass can have a direct relationship with significant positive impacts on health-related selfperceived QoL, both physical and emotional. Moreover, these effects appear to be sustained in the long term, especially in older individuals.
