Fecal microbiota transplantation via fluoroscopy-guided nasojejunal catheter placement: indications, technique, and the role of radiology

摘要

Clostridium difficile is a well-established cause of nosocomial gastrointestinal disease. Although antibiotics remain an effective first-line treatment for C. difficile colitis (CDC), relapse and recurrence are common. FMT has emerged as one of the safest and most effective known therapies available for recurrent or refractory CDC, which is likely due to restoration of the protective microbiotic barrier of the gastrointestinal tract. FMT varies greatly across institutions by route of delivery, dose, and protocol. We present our experience with FMT via fluoroscopic-guided nasojejunal catheter placement. The discussion will include indications and contraindications, protocol, and procedural technique, and include a case presentation incorporating original CT and fluoroscopic images. Specifically, we will address the advantages and disadvantages of image-guided FMT via the upper GI tract with respect to nasogastric-, colonoscopic-, and enema-based delivery. The efficacy of FMT for the treatment of C. difficile has been widely demonstrated in several prospective and case studies. We feel that nasojejunal FMT is an underutilized radiologic procedure which can benefit selected patients, particularly given the advantages in risk profile, cost, convenience, and lack of routine sedation.
