Signo de la cuerda en enfermedad inflamatoria intestinal

Authors: Drs. Tomás Cermenati B, Claudio Cortés A

The "String Sign” corresponds to an image displayed on oral contrast study of the gastrointestinal tract. It is seen as a thin strip of barium resembling a frayed cotton rope which results from a severe narrowing of the bowel loops. This radiographic finding is caused by irritability and ulceration associated with severe spasms, generally secondary to Crohn’s disease. It may appear in both stenotic and nonstenotic stages of the disease.
