Why the study?

Few studies have investigated the correlation between visceral fat area and early postoperative complications in patients with obesity undergoing bariatric surgery.

Does high visceral fat area predict early postoperative complications in patients with obesity undergoing bariatric surgery?

Population

152 patients with obesity undergoing laparoscopic sleeve gastrectomy

Comparison

Umbilical level VFA ≥ 100 cm 2 vs umbilical level VFA < 100 cm 2

Design

Single-center observational study

Implication

Should not yet change LSG risk assessment; leaves open prospective validation of VFA as an independent preoperative marker.

Structured PICO

Does high visceral fat area predict early postoperative complications in patients with obesity undergoing bariatric surgery?

P
Population
152 patients with obesity (aged 16-65 years, BMI ≥28 kg/m2) who underwent selective laparoscopic sleeve gastrectomy under general anesthesia at a tertiary university hospital in China between June 2016 and October 2020.
I
Intervention
High visceral fat area (umbilical level VFA ≥ 100 cm2)
C
Comparator
Low visceral fat area (umbilical level VFA < 100 cm2)
O
Outcome
Early postoperative complications (within 30 days following surgery, including anastomotic leakage, intestinal obstruction, infectious complications, and cardiovascular events)composite

Excess visceral fat area is an independent risk factor for early postoperative complications following bariatric surgery, suggesting its utility in preoperative risk stratification.

Limitations

  • Single-center study
  • BMI cut-off value of 28 kg/m2 for Asian populations limits generalizability
  • Short follow-up time with no long-term outcomes
  • Retrospective cohort design cannot control all confounding factors and may cause selection bias
  • Small sample size
  • Missing data due to patients being followed in local hospitals
