Microscopic ileitis in diverted and non-diverted enteric segments: an under-recognized condition with a multifactorial etiology

Microscopic ileitis has been infrequently reported in the literature with the few reported cases usually associated with concurrent microscopic colitis. Having encountered a case of collagenous ileitis involving the diverted distal limb of a loop ileostomy and sparing the proximal limb, we examined additional cases of loop ileostomy, end ileostomy, colostomy, and the accompanying diverted colorectal segment for features of microscopic ileitis and colitis. A total of 101 cases of diverted and non-diverted enteric segments were examined from 37 loop ileostomies, 16 end ileostomies and 12 colostomies status post Hartmann's procedure.
