A preoperative cotininury test for abdominoplasty reduces peri-operative complications

Summary Background Smoking induces complications in plastic surgery, in particular wound healing delays. Despite a 4-weeks’ abstinence asking before and after surgery, some patients denied or hid their consumption. The aim of this study was to evaluate the effectiveness of a cotininury detection test in terms of improvement in outcomes after an abdominoplasty. Material and methods This retrospective cohort study included patients who underwent an abdominoplasty with umbilical transposition and lipoaspiration. Current smokers were asked to stop smoking 4 weeks before and after surgery. After 2013, we performed a preoperative cotininury test for patients having abdominoplasty, with a cancellation of surgery in case of positive result. We analyzed the test's effectiveness on delayed healing and on other complications. Results Two hundred and thirty-five patients were included; 80 were tested and 21,3% had a positive test. There was significantly less delayed healing in the “screening” group than in the “no screening”: 20,3% versus 41,5% ( P  = 0,002). Alike, complications were significantly less frequent in the “screening” group than in the “no screening”: 18,1% versus 42,3% ( P Conclusion The routine use of the cotininury test in preoperative abdominoplasties significantly reduces risk of delayed healing and other serious complications. It is an objective test, which is simple, quick and non-invasive. Smoking cessation must be at least 4 weeks before and after the surgery. Following medical advice to cease smoking by the surgeon and anesthetist, referral to an appropriate tobacco-addiction specialist clinic may be helpful for the patient who has difficulty stopping smoking.
