AI Article Synopsis

  • Visceral obesity is linked to serious health issues, prompting research on the impact of omentectomy combined with bariatric surgery, specifically sleeve gastrectomy (SG).
  • A study conducted on male Wistar rats assessed the effects of SG alone and SG with omentectomy on rats fed either a standard diet or a high-fat diet, measuring various metabolic parameters and inflammatory markers.
  • Results showed that both SG alone and SG with omentectomy reduced weight and improved metabolic markers, but no significant differences were found between the two surgical approaches regarding inflammation or metabolic benefits.

Article Abstract

Background: Visceral obesity has been considered a risk factor for metabolic and cardiovascular complications. In an attempt to reduce the visceral adipose tissue, omentectomy has been proposed to be performed along with bariatric surgery.

Objective: The goal of this study was to evaluate whether omentectomy associated with sleeve gastrectomy (SG) is beneficial to the inflammatory and metabolic profile of rats fed a standard diet (STD) or high-fat diet (HFD).

Setting: University hospital, Brazil.

Methods: For this experiment, male Wistar rats were randomly divided into 6 groups as follows: sham surgery (STD+L or HFD+L), SG alone (STD+SG or HFD+SG), or SG with omentectomy (STD+SGO or HFD+SGO). Anthropometric data and metabolic profiles were evaluated, and the tissue expression of inflammatory markers in the visceral adipose tissue was measured.

Results: In rats with diet-induced obesity treated with SG with or without omentectomy, there was a reduction in weight (HFD+SG: P<.01 and HFD+SGO: P<.05), adiposity (HFD+SG: P<.001 and HFD+SGO: P<.05), plasma levels of glucose (HFD+SG: P<.01 and HFD+SGO: P<.01), plasma levels of C-peptide (HFD+SG: P<.01 and HFD+SGO: P<.001), plasma levels of insulin (HFD+SG: P<.05 and HFD+SGO: P<.001), plasma levels of total cholesterol (HFD+SG: P<.01 and HFD+SGO: P<.01), and tissue expression of TNF-α (HFD+SG: P<.001 and HFD+SGO: P<.01), but there was no statistically significant difference between the groups in which omentectomy was performed or was not.

Conclusion: In this study, we did not observe additional beneficial effects due to omentectomy associated with SG in the metabolic profile and tissue expression of inflammatory markers.
