Use of Preoperative Postbiotic Supplementation in Colorectal Cancer Surgery
The treatment of colorectal cancer, in the absence of metastases, is primarily based on surgical removal. Colorectal surgery, which involves resecting part of the intestine and restoring intestinal continuity, carries a risk of complications. This study aims to evaluate whether oral supplementation with a postbiotic at a dose of 900 mg for 7 days prior to surgery reduces the rate of postoperative complications.
Conditions studied
Cancer (Colon Cancer, Breast Cancer, Lymphoma, Chronic Lymphoma Leukemia, Multiple Myeloma)
About this study
The treatment of colorectal cancer, in the absence of metastases, is primarily based on surgical removal. Colorectal surgery, which involves resecting part of the intestine and restoring intestinal continuity, carries a risk of complications. This study aims to evaluate whether oral supplementation with a postbiotic at a dose of 900 mg for 7 days prior to surgery reduces the rate of postoperative complications.
Interventions
- Dietary Supplement: Postbiotic — Butyrate directly influences the gastrointestinal microbiota and exhibits potent anti-inflammatory effects by locally inhibiting inflammatory mediators in the intestinal epithelium, thereby enhancing mucosal barrier integrity. It also mitigates excessive inflammation through the modulation of immune cells, promoting the activity of M2 macrophages and regulatory T cells. Furthermore, butyrate is thought to modulate intestinal receptor hypersensitivity, leading to reduced intraluminal pressure and improved peristaltic function. This mechanism may underlie its therapeutic role in clinical conditions associated with diarrhea and in preventing the loss of water, sodium, chloride, and potassium.
- Other: Placebo — Participants will receive three oral capsules per day, containing no active substance and identical in appearance to the study capsules, for seven consecutive days.
Primary outcomes
- Postoperative complications within 30 days (Clavien-Dindo grade II or higher) (30 days after colorectal cancer surgery)
