[The effect of body mass index on outcome of body contouring surgeries]. / Influence de l'indice de masse corporelle sur les complications des chirurgies de séquelles d'amaigrissement.

ABSTRACT

BACKGROUND: The generalization of bariatric surgery interventions has led in recent years to an explosion in demand for body contouring surgeries. These operations can be followed by postoperative complications; and residual obesity, defined by a BMI≥30, is traditionally considered as a relative contraindication. The objective is to study the influence of a BMI≥30 on the risk of postoperative complications. METHODS: A retrospective study was conducted on all patients who underwent body contouring surgery between 2014 and 2020 at the Arras Hospital Center. Major complication rates were compared in obese and non-obese patients. RESULTS: Two hundred twenty-three patients were included, representing a total of 247 surgeries 124 in the BMI<30 group and 123 in the BMI≥30 group. Sixteen surgeries were followed by at least one major complication, 6 in group I versus 10 in group II (RR=1.7 (0.6-4.5), NS, P=0.29). Therefore there were not significantly more major complications in obese patients. CONCLUSION: The incidence of major complications following body contouring surgeries is not modified by the presence of a BMI greater than 30, subject to a precautionary procedure adapted to each patient. BMI is therefore not a sufficient criterion to contraindicate this type of surgery.
