When BMI Fails to Measure Up: Perinephric and Periumbilical Fat as Predictors of Operative Risk
Structured Abstract Background Obesity has been associated with worse outcomes and increased surgical technical difficulty. Perinephric fat (PNF) and periumbilical fat (PUF) are alternative metrics to BMI. We hypothesized that PUF and PNF would offer improved prediction of perioperative risk. Method...

| description | Structured Abstract Background Obesity has been associated with worse outcomes and increased surgical technical difficulty. Perinephric fat (PNF) and periumbilical fat (PUF) are alternative metrics to BMI. We hypothesized that PUF and PNF would offer improved prediction of perioperative risk. Methods 249 patients were retrospectively reviewed after elective, pelvic colorectal resections. PNF and PUF were collected using axial imaging. Operative risk measurements included estimated blood loss (EBL) and operative time (OT). Results In multivariate analyses of women, PUF and PNF were significant predictors of EBL; PNF was a significant predictor of OT. A 4.7 mm increase in PNF predicted a 15 min increase in OT and 55 cc increase in EBL. An 8.6 mm increase in PUF predicted a 55 cc increase in EBL. In men no metric was predictive. Conclusions In women, PNF and PUF may offer improved metrics for risk stratification, which can have important clinical and financial implications. |
