A rare case of acute obstructive suppurative pancreatic ductitis (AOSPD) which developed pyogenic spondylitis.

Acute obstructive suppurative pancreatic ductitis (AOSPD) is an acute suppuration of the pancreatic duct. Endoscopic retrograde cholangiopancreatography (ERCP) drainage and intravenous antibiotics treatment is the mainstay of therapy. Herein we describe an extremely rare case of AOSPD leading to pyogenic spondylitis. A 61-year-old male with a past medical history of chronic pancreatitis and diabetes mellitus presented to our hospital with abdominal and dorsal pain, fever, and shock status. Laboratory data showed severe inflammation, disseminated intravascular coagulation, and normal pancreatic enzymes. Computed tomography showed dilated main pancreatic duct and surrounding pancreatic abscesses. Spinal abnormalities were not detected at this point. He was initially diagnosed as infected pancreatic pseudocyst, but did not respond well to conservative intravenous antibiotic treatment. ERCP performed one week later revealed purulent pancreatic juice and the diagnosis was changed to AOSPD. Upon ERCP, we experienced technical difficulty in passing obstructing calculi. However, successful pancreatic drainage was achieved using new dilation and penetration devices. The patient responded quickly to drainage, but later developed pyogenic spondylitis. Our case highlights the difficulty of diagnosing AOSPD, the usefulness of new devices in urgent endoscopic drainage, and underscores the possibility of progression of pyogenic spondylitis even after adequate treatment.
