Hypothesis
Having more skeletal muscle and less body fat postoperatively would be associated with weight loss.
Conclusion
The effects of laparoscopic sleeve gastrectomy on weight loss were maintained up to 24 months postoperatively.
Supporting Evidence
- The median percentage of total weight loss at 24 months after surgery was 15.6%.
- Skeletal muscle mass to fat mass ratio at 12 months was positively correlated with weight loss at 24 months.
- Patients who lost more weight had higher skeletal muscle mass and lower body fat.
Takeaway
This study looked at how people's bodies changed after a weight loss surgery called laparoscopic sleeve gastrectomy, finding that keeping muscle helps keep the weight off.
Methodology
This was a prospective observational cohort study of patients who underwent laparoscopic sleeve gastrectomy, analyzing body composition and weight loss over 24 months.
Potential Biases
Potential bias due to the single-center design and limited sample size.
Limitations
The sample size may limit the ability to detect significant trends and associations, and the absence of data on physical activity levels and nutritional intake restricts detailed analysis.
Participant Demographics
Median age was 49 years, with 14 men and 19 women.
