[Decontamination in colorectal surgery]

Area of Science:

• Colorectal Surgery
• Surgical Oncology
• Infectious Disease

Context:

• Colorectal diseases necessitate surgical intervention, often involving procedures with a risk of infectious complications.
• Perioperative care protocols aim to minimize surgical site infections and other adverse events.
• Antibiotic prophylaxis is a standard component of surgical preparation for gastrointestinal procedures.

Purpose:

• To evaluate the efficacy of perioperative antibiotic prophylaxis in patients undergoing colorectal surgery.
• To assess the impact of metronidazole plus a cephalosporin regimen on anastomotic integrity, wound suppuration, pneumonia, and lethality.
• To compare outcomes between scheduled and emergency colorectal operations.

Summary:

• A study of 136 patients undergoing colorectal surgery evaluated perioperative decontamination using metronidazole and cephalosporins.
• Patients received either scheduled (74) or emergency (62) operations, with primary anastomoses performed in 32 and 14 cases, respectively.
• Anastomotic insufficiency rates were 3.5% (scheduled) vs. 15% (emergency), wound suppuration 5.4% vs. 13%, and lethality 1.3% vs. 19% (p < 0.001). Postoperative pneumonia rates were 4% vs. 9.6%. No wound dehiscence occurred in either group.

Impact:

• Perioperative antibacterial prophylaxis demonstrates effectiveness in reducing systemic and local inflammatory complications in colorectal operations.
• The findings support the use of this antibiotic regimen to improve safety and outcomes in both elective and urgent colorectal surgeries.
• This evidence contributes to optimizing antibiotic stewardship and patient care protocols in gastrointestinal surgery.
