He theorizes that the smooth muscle coats of the gut relax following injury to the overlying mucosa. The usual response to trauma is contraction.He refers to a case of razor blade ingestion, and leaves one with the impression that this is a relatively innocuous pastime.

An abdominal flat plate localized them in the gastric lumen. Laparotomy and gastrotomy yielded the fragments plus a good deal of bright red blood, as well as a 4-cm laceration of the gastric mucosa on the lesser curvature. This series of one case leaves me with a considerably
