CytoSorb in a case of caecum perforation and fecal 4-quadrant peritonitis

Friedrich Nestler, Hospital Erlabrunn


This case study reports on a 76-year-old male patient who underwent emergency laparotomy due to an acute abdomen after a previous total hip replacement surgery.


Case presentation

  • Intraoperatively confirmed colon perforation with 4 quadrant fecal peritonitis
  • On admission to ICU after preceeding surgery the patient was in septic shock with need for high catecholamine doses and mechanical ventilation
  • Due to concomitant onset of renal failure with highly elevated inflammatory and infection markers (leucocytes 18.3, PCT 14.2, IL-6 >5000, CRP 459), the patient was started on renal replacement therapy in combination with CytoSorb


  • Three consecutive CytoSorb treatment sessions of 24 hours each over a total period of 72 hours
  • Cytosorb was used in conjunction with CRRT (Baxter BM11a/BM14) in CVVHF mode
  • Blood flow rate: 140 ml/min
  • Anticoagulation: citrate
  • CytoSorb adsorber position: pre-hemofilter


  • IL-6, PCT, CRP, leucocytes
  • Demand for catecholamines
  • Renal function (diuresis, creatinine, urea)


  • Hemodynamic stabilization of the patient with significantly decreased needs for catecholamines
  • Effective reduction of IL-6 levels down to 200 pg/ml after the last treatment
  • Declining plasma levels of CRP and PCT during the three CytoSorb sessions
  • Marked improvement of renal function with onset of spontaneous diuresis and decreasing retention parameters

Patient Follow-Up

  • In the further course secondary wound infection with local abdominal wall infection, requiring intraabdominal lavage, debridement and ultimately secondary abdominal wall closure
  • Delayed weaning, critical illness polyneuropathy
  • Successful transfer of the patient to a neurologic rehabilitation unit in the further course


  • Treatment with CytoSorb resulted in a significant stabilization of hemodynamics with declining needs for catecholamines, an effective reduction of inflammatory markers as well as a considerable improvement of kidney function
  • Handling of the absorber was safe and easy after an initial training phase
