Microbiota-anastomotic Leak Among Colorectal Surgery Patients : Pilot Study
- Conditions
- Colorectal CancerInflammatory Bowel DiseasesMicrobiotaAnastomotic Leak
- Registration Number
- NCT03496441
- Lead Sponsor
- Centre hospitalier de l'Université de Montréal (CHUM)
- Brief Summary
The study is based on the hypothesis that patients with postoperative anastomotic leakage have a different bacterial profile contributing to poor tissue healing, and that patients operated for colon cancer presumably have a different preoperative microbiota than healthy patients. This different composition is probably induced by the high heme level in the light intestinal tract that tumor spoliation generates.
The objective of the study is to evaluate the feasibility of a larger study to evaluate the difference between microbiota composition of patients with and without colorectal cancer, with inflammatory bowel disease and those with and without anastomotic leakage postoperatively of a colonic resection.
Stool samples will be taken from 20 patients, including 5 without intestinal pathology, 5 with colorectal cancer undergoing colorectal surgery, 5 with inflammatory bowel disease and 5 with anastomotic leakage after colectomy for colorectal cancer or inflammatory bowel disease.
The stool samples will be analyzed at CRCHUM to draw up a profile of the bacteria that make up the microbiota of each patient.

Study & Design
- Study Type
- OBSERVATIONAL
- Study Design
- Not specified
- Primary Outcome Measures
Name Time Method Evaluate the feasibility of patients' recruitment 3 months Evaluate if we can recruit all required patients easily ; 20 patients total and 5 patients per group (Yes or No).
Evaluate the feasibility of fecal samples' analysis 3 months Evaluate if we can easily perform the fecal sample analysis with the establish procedures (Yes or No).
- Secondary Outcome Measures
Name Time Method Evaluation the presence of a correlation between fecal microbiota composition and the risk of anastomotic leak. 6 months If it is possible to obtain results from the fecal samples' analysis, a possible correlation in the results will be evaluate.
