Brief 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 Measures

Primary Outcomes (1)

  • 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 Outcomes (1)

  • Incidence of adverse events related to treatment

    8-12 weeks after start of treatment.

Other Outcomes (2)

  • Fecal microbiota

    8-12 weeks after start of treatment.

  • Intestinal microbiota metabolites

    8-12 weeks after start of treatment.

Study Arms (2)

Live Combined Bifidobacterium and Lactobacillus

EXPERIMENTAL

The experimental group receive basic treatment and a single infusion of Live Combined Bifidobacterium and Lactobacillus solution through colonoscopy.

Drug: Live Combined Bifidobacterium and LactobacillusDrug: Basic treatment

Control

PLACEBO COMPARATOR

The control group receive basic treatment and a single injection of normal saline through colonoscopy.

Drug: Normal salineDrug: Basic treatment

Interventions

The invesitigators give patients Live Combined Bifidobacterium and Lactobacillus solution infusion during their colonoscopy examination for a single time in the Live Combined Bifidobacterium and Lactobacillus group.

Also known as: Live combined Bifidobacterium and Lactobacillus solution infusion through colonoscopy
Live Combined Bifidobacterium and Lactobacillus

The invesitigators give patients normal saline as a placebo infusion during their colonoscopy examination for a single time in the control group.

Also known as: Normal saline as placebo infusion through colonoscopy
Control

The invesitigators give patients general treatment and drug treatment including oral Live Combined Bifidobacterium and Lactobacillus tablets as basic treatment.
