For non-diabetic women with severe obesity and metabolic syndrome who had gastric bypass surgery, adding omentum removal helped maintain their body's insulin response to sugar after one year, while those without it saw a decline.
Scientific Claim
In non-diabetic premenopausal women with metabolic syndrome and severe obesity, omentectomy during gastric bypass surgery preserved acute insulin response to glucose levels after 12 months compared to gastric bypass alone.
Original Statement
“Among non‐diabetic subjects, omentectomy was associated with a preservation of baseline AIR after 12 months (as opposed to deterioration in the control group)”
Evidence Quality Assessment
Claim Status
appropriately stated
Study Design Support
Design supports claim
Appropriate Language Strength
association
Can only show association/correlation
Assessment Explanation
The abstract uses 'was associated with' language, which is appropriate for the study design as it compares two surgical procedures without isolating visceral fat removal as a standalone intervention.
