Three examples of WSC-SE performed via colostomy. a After recent Hartmann’s surgery, retrograde opacification of closed rectal stump (o) was performed prior to WSC-SE at the descending colostomy. b In a different patient, WSC-SE performed at the efferent limb of a double-barrelled colostomy at the left iliac fossa depicts the diverted rectosigmoid tract. c at the end of a WSC-SE study, contrast opacifies the vagina (arrowhead) indicating the presence of a rectovaginal fistula
