Acute pancreatitis is a common gastrointestinal disease. Supportive therapy is sufficient for treating acute pancreatitis in most cases without complication. However, few severe acute pancreatitis patients require intensive care with high mortality rate. We herein report a patient with hypertriglyceridemia-induced acute pancreatitis that progressed to multiple organ failures including septic shock, acute kidney injury, and acute respiratory distress within 72 hours. The condition of the patient was improved and released from ICU after treating with plasma exchange, continuous venous-venous hemofiltration, and extracorporeal membrane oxygenation. Serum level of triglyceride had been significantly reduced after plasma exchange treatment. Therapeutic plasma exchange can be an effective complementary therapy for patients with acute pancreatitis associated with hypertriglyceridemia.
