For women with severe obesity and metabolic syndrome who had gastric bypass surgery, adding the removal of the omentum fat led to more weight loss over time compared to just the bypass alone.

Scientific Claim

In premenopausal women with metabolic syndrome and severe obesity, omentectomy during gastric bypass surgery was associated with greater weight loss at 1, 6, and 12 months post-surgery compared to gastric bypass alone.

Original Statement

“Omentectomy was associated with greater weight loss at all time points.”

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.

Similar Assertions

Adding omentum removal to gastric bypass surgery didn't change levels of hormones produced by fat tissue (adipokines) in women with severe obesity and metabolic syndrome.

91%

Non-diabetic women with severe obesity and metabolic syndrome who had gastric bypass surgery with omentum removal had better overall insulin function (disposition index) at 6 and 12 months compared to those who only had the bypass.

91%

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.

86%

Women with severe obesity and metabolic syndrome who had gastric bypass surgery with omentum removal had lower levels of a marker for inflammation (CRP) after one year compared to those who only had the bypass.
