Impact of Smoking on Perioperative Pulmonary and Upper Respiratory Complications After Laparoscopic Gynecologic Surgery

The authors retrospectively identified all patients who underwent laparoscopic gynecologic surgery at one institution for 9 years and analyzed them by smoking status. The rate of pulmonary complications was 2.1% (12 of 564 patients) in never smokers, 4.5% (7 of 156 patients) in past smokers, and zero in current smokers.”
