Key result
Adding omentectomy to Roux-en-Y gastric bypass surgery in obese patients resulted in no significant difference in metabolic or inflammatory outcomes compared to gastric bypass alone.
Why the study?
Does omentectomy added to RYGB surgery improve metabolic variables and inflammatory markers in obese patients?
Population
22 obese patients undergoing Roux-en-Y gastric bypass (RYGB) surgery
Comparison
Omentectomy added to Roux-en-Y gastric bypass… vs Roux-en-Y gastric bypass (RYGB) surgery alone
Design
Editorial, Randomized (referring to the discussed trial)
Follow-up
1 year

Implication
This editorial highlights that surgical removal of visceral fat (omentectomy) during gastric bypass does not provide additional metabolic benefits, suggesting increased visceral fat may not directly cause metabolic dysfunction.

Population
22 obese patients undergoing Roux-en-Y gastric bypass surgery, randomized to surgery with or without omentectomy and followed for 1 year.

This editorial highlights that surgical removal of visceral fat (omentectomy) during gastric bypass does not provide additional metabolic benefits, suggesting increased visceral fat may not directly cause metabolic dysfunction.
Limitations
- The overwhelming effect of weight loss induced by RYGB surgery may have masked the potential therapeutic effects of removing visceral adipose tissue.
- Outcome measures may not have been sensitive enough to detect metabolic improvements, particularly in insulin sensitivity.

Samuel Klein (2010) conducted an editorial in Obesity (n=22). Omentectomy vs. Roux-en-Y gastric bypass (RYGB) alone was evaluated on Metabolic variables and circulating inflammatory proteins and adipokines. Adding omentectomy to Roux-en-Y gastric bypass surgery in obese patients resulted in no significant difference in metabolic or inflammatory outcomes compared to gastric bypass alone.
