Evaluating the impact of lifting mandatory smoking cessation prior to elective abdominal wall reconstruction. A...

Many studies identify active smoking as a significant risk factor for postoperative wound and mesh complications in patients undergoing abdominal wall reconstruction surgery. However, our group conducted an analysis using data from the ACHQC database, which revealed similar rates of surgical site infection (SSI) and surgical site occurrence requiring procedural intervention (SSOPI) between active smokers and non-smokers As a result, the Cl eveland Clinic Center for Abdominal Core Health instituted a policy change where active smokers were no longer subject to surgical delay. Our study aims to evaluate the impact of active smoking on the outcomes of these patients.

We identified active smoking patients who had undergone open, elective, clean ventral hernia repair (VHR) with transversus abdominis release (TAR) and permanent synthetic mesh at Cleveland Clinic Foundation. Propensity matching was performed to create a 1:3 ratio of "current-smokers" and "never-smokers" and compared wound complications and all 30-day morbidity between the two groups.

106 current-smokers and 304 never-smokers were matched. Demographics were similar between the two groups after matching, with the exception of chronic obstructive pulmonary disease (COPD) (22.1% vs. 13.4%, p ​< ​.001) and body mass index (BMI) (31.1 vs. 32.6, p ​= ​.02). Rates of SSI (12.2% vs. 6.9%, p ​= ​.13), SSO (21.7% vs. 13.2%, p ​= ​.052), SSOPI (11.3% vs. 6.3%, p ​= ​.13), and reoperation (1.9% vs. 3.9%, p ​= ​.53) were not significantly different between active smokers and never-smokers correspondingly. One case (0.3%) of partial mesh excision was observed in the never-smokers group (p ​= ​1). The current-smokers group exhibited a significantly higher incidence of pneumonia compared to the never-smokers group (5.7% vs. 0.7%, p ​= ​.005).

Our study revealed that operating on active smokers did result in a slight increase in wound morbidity, although it did not reach statistical significance. Additionally, pulmonary complications were higher in the smoking group. Notably, we did not see any mesh infections in the smoking group during early follow up. We believe that this data is important for shared decision making on patients that are actively smoking contemplating elective hernia repair.
