title: Perforated jejunal diverticulum in the use of mycophenolate mofetil.
abstract: BACKGROUND
  Jejunal diverticulosis is a rare disease. Common acute complications include diverticulitis, intestinal obstruction, bleeding and perforation. Gastrointestinal tract perorations have also been rarely observed in the use of mycophenolate mofetil.
  
  
  METHODS
  We report a 44-year-old man with end-stage renal disease post failed kidney transplant on low-dose mycophenolate mofetil who presented with acute onset of abdominal pain. He was successfully given the diagnosis of perforated jejunal diverticulum. The patient successfully underwent a segmental jejunal resection and anastomosis. He unfortunately developed a recurrent jejunal perforation a month later and again had the second segmental jejunal resection operation. Mycophenolate mofetil then was discontinued.
  
  
  CONCLUSIONS
  The present case illustrates jejunal diverticulum perforation in the use of mycophenolate mofetil. Physicians should increase the awareness of this association of perforated jejunal diverticulum in patients using mycophenolate mofetil.
