Overview
Brief Summary
The purpose of this study is to evaluate the effect of fecal microbiota transplantation in adults with slow transit constipation.
Detailed Description
Constipation is a chronic disease estimated to affect about 10% - 15% of the worldwide general population. Constipation frequency appears to augment with increasing age, particularly after 65 years old. Recent evidence in the literature and collected in the investigators' laboratory confirm that constipation can be a consequence of intestinal dysbiosis, with an increase of potentially pathogenic microorganisms and a decrease of potentially beneficial microorganisms. These alterations may affect the motility and metabolic environment of colon, especially the production of short chain fatty acids (SCFAs). A new and under-explored method to manipulate the gastrointestinal microbiota involves fecal microbiota transplantation (FMT). There has been growing interest in the use of fecal microbiota for the treatment of patients with chronic gastrointestinal infections (e.g. CDI) and other extraintestinal conditions (e.g. IBD). Similarly, the investigators suppose that reshaping the gut microbiome with FMT would be effective for patients with slow transit constipation.

Eligibility Criteria
Inclusion Criteria

- •Age ≥ 18 years;
- •BMI: 18.5-25 kg/m2;
- •Slow colonic transit confirmed by colonic transit test (colonic transit time (CTT) \> 48 hours);
- •Normal anorectal manometry, with no evidence of dyssynergia and confirmed ability to expel rectal balloon;

- •Traditional treatment with dietary modification, laxatives (including osmotic and stimulant laxatives), and biofeedback tried over the past 6 months without success;
Exclusion Criteria
- •Bowel constipation due to innate factor (i.e. megacolon) or secondary interventions (i.e. drugs, endocrine, metabolic, neurologic or psychologic disorders);
- •History or evidence of gastrointestinal diseases (i.e. obstruction, cancer, inflammatory bowel diseases) ;
- •Previous abdominal surgery, except cholecystectomy, appendicectomy, tubal ligation and cesarean section;
- •Previous proctological or perianal surgery;
- •A constipation condition meeting the Rome III criteria for IBS or functional abdominal pain syndrome;
- •Pregnant or breast-feeding women;

- •Smoking or alcohol addiction within the last 3 months;
Arms & Interventions
Fecal microbiota transplantation (FMT)
On day 1-6, patients received 100ml fresh FMT by nasointestinal tube, once per day. The nasointestinal tube was placed in the patient's proximal jejunum through endoscopy. Then, donor fecal microbiota was infused within 5 minutes through nasointestinal tube.

Intervention: Conventional treatment
Conventional treatment
Conventional treatment was taken by both of two groups. If patients did not have a bowel movement for 3 or more consecutive days, they were permitted to take up to 20 g of Macrogol 4000 powder (Forlax®, Ipsen, Paris, France). If ineffective, an enema could be used.
