The Impact of Surgical Bowel Preparation on the Microbiome in Colon and Rectal Surgery

Area of Science:

• Microbiome Research
• Surgical Outcomes
• Gastrointestinal Surgery

Background:

• Preoperative bowel preparation is standard practice in colon and rectal surgery, aiming to improve surgical outcomes.
• The precise impact of bowel preparation on the human gut microbiome remains incompletely understood.
• The gut microbiota is dynamic and influenced by various factors including diet, injury, and metabolism.

Purpose of the Study:

• To review the current understanding of how surgical bowel preparation affects the adult gut microbiome.
• To highlight knowledge gaps concerning the specific pathways linking bowel preparation to microbiome alterations.
• To identify key questions for future microbiome research in the context of colorectal surgery.

Main Methods:

• Literature review of existing studies on preoperative bowel preparation and its effects on the gut microbiome.
• Analysis of current evidence regarding the components of bowel preparation (e.g., oral antibiotics, mechanical cleansing).
• Synthesis of information on the sensitivity of the gut microbiota to surgical interventions.

Main Results:

• Bowel preparation, including oral antibiotics and mechanical cleansing, can significantly alter the gut microbiota.
• These alterations may have previously underestimated detrimental effects on patients undergoing intestinal surgery.
• Evidence suggests the gut microbiota is sensitive to antibiotics, bowel preparation, and the surgical process itself.

Conclusions:

• Understanding the microbiome's response to bowel preparation is crucial for refining perioperative care.
• Further research into specific causal pathways is needed to develop targeted therapeutic interventions.
• Optimizing bowel preparation strategies based on microbiome insights could lead to improved patient outcomes in colorectal surgery.
