title: Abdominal catastrophe: visceral injury as a cause of peritonitis in patients treated by peritoneal dialysis.
abstract: OBJECTIVE
  Peritonitis is considered an acceptable and controllable risk in patients undergoing chronic peritoneal dialysis (PD). In contrast, peritonitis due to visceral leakage represents a true "abdominal catastrophe" because of striking morbidity and mortality. To delineate the incidence, causes, and outcomes of catastrophic peritonitis, we compared patients who developed peritonitis due to documented visceral leakage with patients who developed peritonitis due to enteric organisms without evidence of visceral leakage.
  
  
  METHODS
  Retrospective chart review.
  
  
  METHODS
  PD Unit located in tertiary care referral center.
  
  
  METHODS
  230 patients treated by PD between January 1988 and June 1996.
  
  
  METHODS
  All episodes of PD-related peritonitis occurring over an 8-year period. Hospital course of all patients with or without renal failure who were treated at University Hospitals of Cleveland for ischemic bowel disease, cholecystitis, viscus perforation, or diverticulitis.
  
  
  RESULTS
  Anatomically documented visceral injury caused 32.5% of episodes of enteric bacterial peritonitis in 72 patients between January 1988 and June 1996. The overall incidence of this "abdominal catastrophe" was 11.3%, or 26 of a total of 230 patients treated by PD. Of the 26 patients, 50% died, 30.7% survived but switched permanently to hemodialysis, and only 19.2% remained on, or returned to, PD. Compared to renal failure patients treated by hemodialysis or transplantation and to non-renal failure patients, the incidence of abdominal catastrophe was 20-60 times greater in patients treated by PD.
  
  
  CONCLUSIONS
  Evidence for injury of an abdominal organ should be sought in all patients treated by PD who develop peritonitis with enteric organisms. Surgical intervention is definitive for diagnosis, and if performed early may reduce morbidity and mortality.
