Summary: | Purpose
Despite increasing use of cannabis, literature on perioperative effects is lagging. We compared active cannabis-smokers versus non-smokers and postoperative wound morbidity and reoperations following open abdominal wall reconstruction (AWR).
Methods
Patients who underwent open, clean, AWR with transversus abdominis release and retromuscular synthetic mesh placement at our institution between January 2014 and May 2022 were identified using the Abdominal Core Health Quality Collaborative database. Active cannabis-smokers were 1:3 propensity matched to non-smokers based on demographics and comorbidities. Wound complications, 30 day morbidity, pain (PROMIS 3a-Pain Intensity), and hernia-specific quality of life (HerQles) were compared.
Results
Seventy-two cannabis-smokers were matched to 216 non-smokers. SSO (18% vs 17%
p
= 0.86), SSI (11.1% vs 9.3%,
p
= 0.65), SSOPI (12% vs 12%,
p
= 0.92), and all postoperative complications (46% vs 43%,
p
= 0.63) were similar between cannabis-smokers and non-smokers. Reoperations were more common in the cannabis-smoker group (8.3% vs 2.8%,
p
= 0.041), driven by major wound complications (6.9% vs 3.2%,
p
= 0.004). No mesh excisions occurred. HerQles scores were similar at baseline (22 [11, 41] vs 35 [14, 55],
p
= 0.06), and were worse for cannabis-smokers compared to non-smokers at 30 days (30 [12, 50] vs 38 [20, 67],
p
= 0.032), but not significantly different at 1 year postoperatively (72 [53, 90] vs 78 [57, 92],
p
= 0.39). Pain scores were worse for cannabis-smokers compared to non-smokers at 30 days postoperatively (52 [46, 58] vs 49 [44, 54],
p
= 0.01), but there were no differences at 6 months or 1 year postoperatively (
p
> 0.05 for all).
Conclusion
Cannabis smokers will likely experience similar complication rates after clean, open AWR, but should be counseled that despite similar wound complication rates, the severity of their wound complications may be greater than non-smokers. |
