Acute obstructive suppurative pancreatic ductitis (AOSPD) in pancreatic cancer treated by nasopancreatic drainage.

An 80-year-old woman with pancreatic cancer was admitted with fever and abdominal pain. Blood examinations showed an elevated CRP level. On computed tomography (CT), a pancreatic tumor with a dilated upstream main pancreatic duct (MPD) was seen. Endoscopic retrograde cholangiopancreatography (ERCP) showed the strictured part of the MPD at the head of the pancreas with upstream dilatation. A nasopancreatic drainage tube was placed. Through the tube, purulent pancreatic juice was discharged and culture of the pancreatic juice grew Klebsiella pneumoniae. On the day after ERCP, the patient's condition and the laboratory results improved. The patient's disorder was diagnosed as acute obstructive suppurative pancreatitis with pancreatic cancer.
