Autologous faecal microbiota transplantation via double barrel stoma to treat chronic diversion colitis.

Diversion colitis is a common phenomenon affecting patients after defunctioning ileostomy. We present a complex case of diversion colitis where the patient was deemed unsuitable for restorative surgery due to multiple areas of stricturing in a long defunctioned colonic segment. Despite initial treatments with rectally administered topical mesalazine, butyrate enemas and topical steroid therapy, the patient remained symptomatic with rectal bleeding and mucus discharge. Furthermore, the appearance of colitis could be appreciated on endoscopy and radiological investigations with changes in histology consistent with moderate-severe diversion colitis. This article describes our experience in the use of autologous faecal transplant administered via the efferent loop of a double-barrel ileostomy to successfully treat diversion colitis refractory to standard topical therapy.
