It is not clear whether being overweight or obese influences postoperative complications in myasthenia gravis (MG) patients. We retrospectively investigated an association between body mass index (BMI) and postoperative complications in MG.
- MATERIALS AND METHODS:
Fifty-nine MG patients who had undergone transsternal thymectomy were classified as low or high BMI based on the criteria for Asian-Pacific populations. An association between BMI and complications was analyzed.
MG patients with high BMI had significantly higher rates of major adverse complications (P = 0.033), postoperative respiratory failure (P = 0.045), and longer postoperative hospitalization (P = 0.005). The optimal cutoff value of BMI for postoperative respiratory failure was 23.3 kg/m2, with a sensitivity of 75.0% and a specificity of 64.7% (P = 0.046).
MG patients with a BMI indicating overweight or obesity have a higher risk of postoperative complications after thymectomy. Thus, close monitoring must be performed when surgery is necessary.
