Deep Inferior Epigastric Perforator Flap Reconstruction Outcomes Across Body Mass Index Categories: A Retrospective Study.

Complication rates were generally low across BMI groups.

Abdominal seroma ( P = 0.038) occurred significantly more often in patients with a BMI 30 kg/m 2 or higher.

Fat necrosis and total flap loss occurred exclusively in the obese group, with rates of 7.1% in each, and both findings approached statistical significance ( P = 0.056).

No significant differences were observed in rates of infection, wound dehiscence, hernia, or flap loss.
