title: Acute acalculous cholecystitis following coronary artery bypass surgery.
abstract: BACKGROUND
  Significant gastrointestinal complications following cardiac surgery requiring cardiopulmonary bypass (CPB) are relatively infrequent but are associated with high morbidity and mortality rates. Acute acalculous cholecystitis (AAC) may be a devastating complication if the diagnosis is missed or management delayed.
  
  
  OBJECTIVE
  We present two cases of AAC that followed coronary artery bypass graft (CABG) surgery.
  
  
  RESULTS
  In one case a cholecystectomy was performed whereas percutaneous drainage was utilised in the second case. The application of these two different individualised treatment options lead to successful outcomes in both cases.
  
  
  CONCLUSIONS
  Awareness with vigilance enables early diagnosis and treatment. The clinical state of the patient at the time of diagnosis ultimately determines the management strategy in the post cardiac surgery patient.
