閉塞性黄疸および十二指腸狭窄を合併した膵仮性嚢胞に対し超音波内視鏡ガイド下経消化管的嚢胞ドレナージ(EUS-CD)が奏効した1例

Abstract A 40-year-old man was admitted to our hospital because of epigastralgia and vomiting. His condition was diagnosed as acute pancreatitis with a pancreatic pseudocyst, obstructive jaundice, and duodenal stenosis. Because he had fever, abdominal pain, and elevated levels of C-reactive protein (CRP), endoscopic ultrasound-guided transmural cyst drainage (EUS-CD) was performed with a nasocystic tube on the 6th day. After the cyst was reduced and the patient recovered from the obstructive jaundice and duodenal stenosis, the nasal drainage tube was replaced with a plastic stent. Because a short extent of stenosis in the main pancreatic duct in the pancreatic head was found by endoscopic retrograde cholangiopancreatography (ERCP), a 5Fr pancreatic stent was placed to prevent pancreatitis. No recurrence of pancreatitis and the cyst occurred after removal of both stents 5 days later.
