Severe refractory Clostridium difficile infection with good response to fecal microbiota transplantation: a case report.

A 49-year-old woman diagnosed with pseudomembranous enterocolitis was transferred to our hospital for medical treatment. She responded poorly to treatment with vancomycin hydrochloride and metronidazole, so she underwent fecal microbiota transplantation. Treatment effects were observed the next day, and the diarrhea disappeared within 3 days. Colonoscopy 4 days later revealed the resolution of pseudomembranes, and no recurrences were reported within the first year after discharge.
