Fecal Microbiota Transplant
Participants will receive approximately 50 grams of human stool/150mL (approximately 107 microbes/mL of suspension) in saline, prepared as per standard collection, preparation, and screening protocols for FMT infusion developed by our institutional stool bank in accordance with recognized standards. Fecal microbiota transplant infused via existing enteral feeding tube or upper elective endoscopy (with infusion into the duodenum) x1.

Eligibility Criteria

The trial’s own eligibility text, word for word from the registry. Only the trial site can say who takes part.
Inclusion
- +Patients 3-18 years old
- +Patients will discontinue antibiotics for at least 1 week prior to FMT
- +A diagnosis of SIBO established through lactose breath test (LBT), and showing of symptoms of SIBO
Exclusion
- −Participants will not be permitted to start any new treatments (including antibiotics, probiotics, antacid treatments, or antimotility treatments) until Week 8, unless clinically indicated
- −We will exclude participants \<3yo to avoid potential concerns of microbial transmission in young children, and to ensure participants are developmentally able to perform LBT
- −All potential participants should request a referral through their primary, or subspecialty physician. We would be pleased to help facilitate this contact if needed, provided the appropriate contact information can be sent.
