Objective:

To evaluate the effectiveness of different antibiotic regimens in preventing surgical site infections (SSIs) in elective colorectal surgery.

Approach:
    Key Findings:
    • Broad-spectrum penicillins and cephalosporin-based combinations were the most effective in reducing SSI risk.
    • Broad-spectrum penicillins were associated with a 74% relative reduction in SSI risk.
    • They were also the only class linked to reduced all-cause mortality.
    • No significant differences in length of hospital stay or overall adverse event rates among most regimens.
    Interpretation:

    The findings highlight the importance of selecting appropriate antibiotic classes for prophylaxis in colorectal surgery, with broad-spectrum penicillins showing the most consistent efficacy.

    Limitations:
    • Many comparisons were based on small trials with frequent risk of bias.
    • Inconsistent reporting of comorbidities and protocols limited subgroup analyses.
    Conclusion:

    Broad-spectrum penicillins and certain cephalosporin combinations may provide optimal SSI prevention, suggesting a need for guideline updates.
