Jejunal perforation possibly induced by slow-release potassium in a patient with Crohn's disease

A case of small bowel ulceration and perforation possibly due to therapy with Klotrix in a patient with Crohn's disease is presented. Following emergent surgery with creation of a diverting loop jejunostomy, subsequent reestablishment of intestinal continuity was carried out with excellent clinical results. Gastrointestinal mucosal lesions possibly due to wax-matrix potassium chloride preparations are reviewed.
