What this trial studies

This observational study examines the relationship between smoking habits and post-operative complications in patients undergoing colorectal surgery. It involves a national multicenter cohort of patients, divided into three groups: tobacco smokers, those using nicotine replacement therapy, and non-smokers. The first phase collects retrospective data over six months, while the second phase is prospective and lasts one year, allowing for a comprehensive analysis of complications across different smoking statuses. The study aims to determine if smoking significantly influences post-operative outcomes.

Who should consider this trial

Good fit: Ideal candidates include adults aged 18 and older undergoing elective or emergency colorectal surgery in Italy, regardless of their smoking status.

Not a fit: Patients under 18 years old or those who do not provide informed consent will not benefit from this study.

Why it matters

Potential benefit: If successful, this study could lead to improved post-operative care and tailored interventions for colorectal surgery patients based on their smoking habits.

How similar studies have performed: Previous studies have indicated that smoking can adversely affect surgical outcomes, suggesting that this approach may yield valuable insights.
