Results of faecal donor instillation therapy for recurrent Clostridium difficile-associated diarrhoea.

We report a success rate of 83% with faecal donor instillation therapy (FDIT) in this retrospective study of 40 patients with recurrent Clostridium difficile-associated diarrhoea (CDAD), treated at a medium sized Norwegian hospital from 1994 through 2008. The stool transplant was instilled either in the duodenum through a gastroscope or in the colon through a colonoscope with next of kin or other household member as donor. In 29 cases (73%) the first treatment was successful, with no documented recurrence of diarrhoeal disease within 80 days. Of the 11 patients failing to respond to the first instillation treatment, 6 patients received a second instillation, 4 of which were successful. A total of 33 patients (83%) were successfully treated with FDIT. Of the 7 non-responders, 5 were seriously ill due to long lasting diarrhoeal disease and co-morbidity and died within 80 days after the procedure, and 2 were believed to have inflammatory bowel disease with response to corticosteroid treatment. No adverse effects of FDIT were observed. In our experience the procedure is easy to perform, well tolerated, effective, and may be a valuable treatment option in selected cases.
