title: Oxidized regenerated cellulose presenting as a postoperative cyst: a case report.
abstract: BACKGROUND
  Barriers placed intraabdominally may aid in hemostasis and help prevent adhesion formation.
  
  
  METHODS
  A 17-year-old woman presented with acute pelvic pain and a complex pelvic mass. A laparotomy was performed. To ensure hemostasis, Surgicel (Johnson & Johnson Medical, Arlington, Texas) was placed, and Seprafilm (Genzyme Corp., Cambridge, Massachusetts) was used for adhesion prevention. Within the first postoperative day the patient's status deteriorated, with increasing pain and significant pyrexia. Computed tomography was highly suspicious for a bowel injury. Repeat laparotomy found no injury. The Surgicel was removed and the abdomen irrigated. The remaining postoperative course was uneventful.
  
  
  CONCLUSIONS
  Seprafilm has been associated with acute reactions, and Surgicel has mimicked many radiologic abnormalities. It is imperative to inform the radiologist of the intraoperative use of these agents to allow use of a proper imaging modality in the postoperative period and to avoid unnecessary repeat surgeries.
