[Orally administered infection prophylaxis in elective colorectal surgery]

Area of Science:

• Surgical infection prevention
• Pharmacological prophylaxis
• Colorectal surgery outcomes

Background:

• Surgical site infections (SSI) are a significant concern in colorectal surgery.
• Optimizing antibiotic prophylaxis is crucial for patient safety and resource management.
• Environmental considerations are increasingly influencing clinical practice guidelines.

Purpose of the Study:

• To evaluate the efficacy and safety of oral trimethoprim-sulfamethoxazole and metronidazole for infection prophylaxis in elective colorectal surgery.
• To assess the impact on superficial surgical site infections (SSI).
• To explore the potential benefits and limitations in different surgical settings.

Main Methods:

• Prospective evaluation of orally administered trimethoprim-sulfamethoxazole and metronidazole.
• Defined administration timing at least two hours prior to elective colorectal surgery.
• Surveillance for superficial surgical site infections (SSI).

Main Results:

• Oral administration is feasible for prophylaxis, showing a small increase in superficial SSI.
• The regimen may be considered when environmental benefits are a motivating factor.
• Use in upper malignant or bariatric surgery is recommended only within study protocols.

Conclusions:

• Oral trimethoprim-sulfamethoxazole and metronidazole offer a viable prophylactic option in elective colorectal surgery.
• Careful consideration of SSI risk and specific patient populations is necessary.
• Improvements in infection surveillance methodologies are warranted.
