[Orthograde intestinal irrigation as a preoperative intestinal preparation. Reduction of the intestinal flora using
Abstract:
Whole gut irrigation is a now a well-established method of preoperative bowel preparation. Additional reduction of bacterial content is desirable. The influence of neomycin/bacitracin and clindamycin as well as the combination, as admixture to the whole gut irrigation, on the flora of the large intestine, was therefore investigated in a prospective controlled study. While neomycin/bacitracin caused only a reduction of aerobic, and clindamycin of the anaerobic bacteriae, the combination resulted in a nearly total eradication of detectable bacterial content at the time of operation.
Insights
Whole gut irrigation effectively prepares bowels, but adding neomycin/bacitracin or clindamycin selectively reduces bacteria. The combination nearly eradicates all gut flora for optimal preoperative preparation.
Area of Science:
- Gastroenterology
- Microbiology
- Surgical Preparation
Background:
- Whole gut irrigation is a standard preoperative bowel preparation technique.
- Further reduction of intestinal bacterial content is clinically desirable.
- The impact of antibiotics on gut flora during irrigation requires investigation.
Purpose of the Study:
- To investigate the effect of neomycin/bacitracin and clindamycin, alone and in combination, on large intestine flora.
- To assess the efficacy of these antibiotics as admixtures to whole gut irrigation.
Main Methods:
- A prospective controlled study design was employed.
- The study evaluated the influence of neomycin/bacitracin and clindamycin on intestinal flora.
- Antibiotics were administered as admixtures to whole gut irrigation.
Main Results:
- Neomycin/bacitracin reduced aerobic bacteria.
- Clindamycin reduced anaerobic bacteria.
- The combination of neomycin/bacitracin and clindamycin nearly eradicated all detectable bacterial content.
Conclusions:
- Combined neomycin/bacitracin and clindamycin with whole gut irrigation offers superior bacterial reduction.
- This combination significantly enhances preoperative bowel preparation by minimizing gut flora.
- Further research may explore clinical outcomes associated with this enhanced preparation.
