Clinical Trial Summary

The purpose of this project is to study the the efficacy and safety of probiotics implantation through infusion during colonoscopy in the treatment of functional constipation and irritable bowel syndrome. The study is a single-center, prospective, randomized, single-blind, controlled, cohort study. The invesitigators plan to enroll 80 patients with functional constipation and 80 patients with irritable bowel syndrome. The invesitigators will randomize the included study subjects. The experimental group receive basic treatment and a single infusion of probiotics through colonoscopy. The control group receive basic treatment and a single injection of normal saline through colonoscopy. The invesitigators will follow up the patients for 8-12 weeks. The primary endpoint is the efficacy of the single colonoscopic probiotics infusion in functional constipation and irritable bowel syndrome patients. The secondary endpoint is the safety of the single colonoscopic probiotics infusion in functional constipation and irritable bowel syndrome patients. Other exploratory objectives include the alterations in clinical indicators, fecal microbiota, and intestinal microbiota metabolites in feces and serum.

Outcome

Type	Measure	Description	Time frame	Safety issue
Other	Fecal microbiota	16S rRNA detection of fecal intestinal flora.	8-12 weeks after start of treatment.
Other	Intestinal microbiota metabolites	Detection of gut microbiota metabolites in blood and feces by HPLC-MS/MS.	8-12 weeks after start of treatment.
Primary	Proportion of effective patients with functional constipation and irritable bowel syndrome patients	The efficacy of irritable bowel syndrome is evaluated by stool texture and abdominal discomfort related scales including IBS-SSS, BSS score, IBS-QOL,HADS and number of bowel movements per day in 12 weeks after start of treatment. The efficacy of functional constipation is evaluated by weekly defecation frequency, spontaneous complete bowel movement, and scales such as Wexner constipation score, BSS score, and PAC-QOL in 8 weeks after start of treatment.	8-12 weeks after start of treatment.
Secondary	Incidence of adverse events related to treatment	The safety of single colonoscopic probiotics infusion was evaluated by incidence of adverse events related to colonoscopic probiotics infusion during the treatment and 8-12 weeks after the treatment.	8-12 weeks after start of treatment.
