Relationship Between Microbiota of the Colonic Mucosa vs Feces and Symptoms Colonic Transit and Methane Production in Female Patients With Chronic Constipation

摘要

Background & AimsIn fecal samples from patients with chronic constipation, the microbiota differs from that of healthy subjects. However, the profiles of fecal microbiota only partially replicate those of the mucosal microbiota. It is not clear whether these differences are caused by variations in diet or colonic transit, or are associated with methane production (measured by breath tests). We compared the colonic mucosal and fecal microbiota in patients with chronic constipation and in healthy subjects to investigate the relationships between microbiota and other parameters.
