The "Mannit-Ceftriaxon" preparation for elective colorectal surgery

Area of Science:

• Colorectal Surgery
• Surgical Preparation
• Infectious Complications

Background:

• Optimizing patient preparation is crucial for reducing surgical site infections in colorectal procedures.
• Traditional bowel preparation methods often involve purgatives and enemas, with varying efficacy and patient tolerance.

Purpose of the Study:

• To evaluate the efficacy of different preoperative preparation protocols in reducing septic complications after elective colorectal surgery.
• To compare the outcomes of traditional bowel preparation with newer methods involving mannit solution and specific antibiotic regimens.

Main Methods:

• A comparative study involving 450 patients undergoing elective colorectal surgery, divided into three groups based on preparation methods.
• Group 1: Traditional preparation (purgatives, enemas, mycerine + metronidazole).
• Group 2: Mannit solution (10%) orally 12 hours pre-op + intravenous ceftriaxone 2 hours pre-op.
• Group 3: Mannit solution (10%) orally + intravenous ceftriaxone + intravenous metronidazole.

Main Results:

• The mannit solution + ceftriaxone regimen (Group 2) demonstrated satisfactory protection against septic complications.
• Septic complication and mortality rates were higher in the traditional preparation group (Group 1) compared to Groups 2 and 3.
• The addition of metronidazole to ceftriaxone (Group 3) did not show superiority over ceftriaxone alone in preventing septic complications.

Conclusions:

• Preoperative bowel preparation with mannit solution and intravenous ceftriaxone is an effective strategy for elective colorectal surgery, requiring only a 12-hour interval.
• This regimen offers a significant reduction in septic complications compared to traditional methods.
• Combined antibiotic prophylaxis with ceftriaxone and metronidazole offers no added benefit over ceftriaxone alone in this context.
