675 Are Postoperative Outcomes in Flap Operations Affected by Obesity?

Abstract Aim To explore the outcomes of flap surgeries and how obesity affects them. find if there is a correlation between CBC indices (also inflammatory markers) with survival. Method All on adults in collaborating departments an Indian tertiary care hospital from 2021-2022 excluding finger flaps were prospectively analyzed. Data 90 patients including postoperative complications, preoperative Neutrophil-Lymphocyte Ratio (NLR) recorded.BMI calculated to classify based Asia-Pacific guidelines where BMI>25 obese, 23-24.9 overweight, <18 underweight.Chi square tests used assess association obesity, NLR early (within 7 days surgery) &late (beyond days) complications -flap loss, wound dehiscence, surgical site infection. Multiple regression model ANOVA test also done these variables. Results There significant patients’ obese or overweight habitus complications. 38% (p = 0.001) 36% late 0.044) happened alone. 0.002).60% high values had severe compared 16.7% normal 21.1% mildly raised NLR. Obesity [NLR 10-18 moderate stress, NLR>18 stress] independently have (0.038 for 0.015 NLR) Conclusions combined quick, inexpensive predictor poor
