Chronic Loose Stools After Right-Sided Colectomy: How Bile Acids and Gut Bacteria Might Link to Symptoms
Official title: Chronic Loose Stools Following Right-sided Hemicolectomy for Colon Cancer and the Association With Bile Acid Malabsorption and Small Intestinal Bacterial Overgrowth Using a Novel Sampling Device
Run by M.D. Anderson Cancer Center · NCT06927011 · Data updated 2026-11-12
This study tests whether bile acid metabolism and small intestinal bacteria relate to chronic loose stools in patients after right-sided colectomy or total colectomy.

Is this trial a fit for you?
✓Likely a good fit
Adults of any race or ethnicity who have undergone right-sided colectomy or sigmoid colectomy for colon cancer and have persistent gastrointestinal symptoms.
✕Probably not a fit
Patients without post-colectomy symptoms or those not suitable for sampling may not see direct personal benefit.
A plain-English reading of the study's rules. Only the study team can confirm whether you qualify.
What this trial studies
This observational study will collect samples to profile bile acids and gut microbiota at different points in the small intestine and near the remaining colon in patients who had right-sided colectomy or sigmoid colectomy. The goal is to understand how these gut changes relate to persistent gastrointestinal symptoms and quality of life. Participants will undergo the use of a novel sampling device to obtain the required samples. The study is conducted at MD Anderson Cancer Center and does not involve an intervention beyond sampling and observation.
Why it matters
Potential benefit: If successful, findings could help tailor management for symptoms and improve quality of life after colectomy.
How similar studies have gone: Previous research in post-colectomy patients has linked bile acids and microbial changes to symptoms, supporting potential value of this approach.
