Effect of Smoking History on 30-Day Morbidity Following Bariatric Surgery.

SH patients undergoing bariatric surgery were at significantly increased risk of readmission and reoperation within 30 days of procedure. In addition, SH patients were more likely to have unplanned intubation and unplanned ICU admission. Given the higher rates of complications in smoking patients, this study would suggest that preoperative smoking cessation in patients prior to primary bariatric surgery might be beneficial. Further study is warranted to compare short-term cessation vs long-term cessation preoperatively, which was not assessed in our study.
