Management of asparaginase induced hemorrhagic pancreatitis complicated by pseudocyst.

Asparaginase induced hemorrhagic pancreatitis is a rare but serious development occurring in less than 0.5% of patients treated with this drug. Severe pancreatitis with progressive abdominal distention, toxemia, hypotension and respiratory insufficiency occurred in an 18-year-old patient with acute lymphoblastic leukemia following treatment with asparaginase. There was a dramatic response to high flow peritoneal lavage with rapid recovery within 24 hours from a moribund state. The subsequent development of a pseudocyst, with progressive increase in size and development of obstructive symptoms, required surgical decompression. Transgastric cystogastrostomy was successfully carried out.
