BackgroundWe retrospectively reviewed charts of 42 postbariatric patients who underwent mastopexy and breast reduction for body contouring to determine whether a significant relationship existed between cigarette smoking and postoperative wound infections and to determine the relative risk given by cigarettes and a cut-off value to predict infections.MethodsWe excluded patients with ongoing clinical infections, recent bariatric surgery (within 1 year), recent antibiotic courses, or systemic diseases such as arteriosclerosis and diabetes mellitus.ResultsAll patients underwent bariatric surgery with the laparoscopic adjustable gastric bending technique and mastopexy with breast reduction for body contouring. Postoperative infections were present in 35.7% (n = 15) of patients, and 60% of these (n = 9) were superficial. Furthermore, 66.7% of them occurred in smoker patients, and 41.7% of smokers vs. 27.8% of nonsmokers developed infections. Significant differences between infected vs. infection-free patients were present for the number of pack years (p < 0.001) and the overall estimated cigarettes smoked (p < 0.001). A cut-off value of approximately 6.85 pack years (50,000 overall estimated cigarettes) distinguished between infections vs. infections-free patients, with 25% of false positives and 8% of false negatives. Relative risk conferred by smoking was 3.8.ConclusionsThe incidence of infections in our series of postbariatric patients undergoing mastopexy and breast reduction is 35.7%. A cut-off of 6.85 pack years (50,000 estimated overall cigarettes) was determined and, according to this value, the relative risk conferred by smoking was 3.8.
