BACKGROUND Stent insertion is widely performed to restore biliary drainage in hepatic, biliary, and pancreatic obstructive conditions. Intestinal perforation due to the migration of these stents is an extremely rare late-term complication that is associated with a high rate of mortality. The current report aimed at presenting the radiological findings of a case of extraluminal biliary stent mig...

dominal pain and jaundice for 2 months. Computed tomography (CT) revealed a huge mass at the pancreatic head causing distal common bile duct (CBD) obstruction with superior mesenteric vein and superior mesenteric artery encasement (●" Fig. 1). The man underwent endoscopic retrograde cholangiopancreatography (ERCP), but we could not pass the duodenoscope through the duodenum because of tumor inv...

Hemorrhage from ruptured pseudoaneurysm is a rapidly progressing and potentially fatal complication after pancreaticoduodenectomy (PD). Stent graft placement for hepatic artery pseudoaneurysm has recently been reported as a valid alternative to transcatheter arterial embolization (TAE). We report a case of pseudoaneurysm of the common hepatic artery (CHA) with distal arterial stenosis treated b...

For patients recovering from acute pancreatitis, the development of a pancreatic fluid collection (PFC) predicts a more complex course of recovery, and introduces difficult management decisions with regard to when, whether, and how the collection should be drained. Most PFCs resolve spontaneously and drainage is indicated only in pseudocysts and walled-off pancreatic necrosis when the collectio...

We report here the case of a 37-year-old woman and her daughter (now 12 years old) with genetically proven hereditary cationic trypsinogen (PRSS1) deficiency pancreatitis. The two patients were treated in a similar manner: endoscopic extraction of large obstructive stones located mainly in the head of the pancreas upstream of a stricture of the distal (cephalic) pancreatic duct and associated w...

Obstructive chronic pancreatitis in children occurs as a result of congenital or acquired stricture of the pancreatic duct. The prominent histologic changes are characterized by periductal fibrosis and subsequent ductal dilatation. Diagnosis is usually made by imaging studies such as endoscopic retrograde cholangiopancreaticography, ultrasonography, and pancreatic function testing. Eosinophilia...

Duodenal malignant stenosis can be caused by primary duodenal cancer or pancreatic cancer involving the duodenum [1]. Current treatment options include laparoscopic bypass and palliative duodenal stent placement under endoscopic or radiographic guidance. Both methods have their advantages and disadvantages. Surgical methods will cause greater trauma to patients, while a duodenal stent might rem...

A 51-year-old man with abdominal pain was admitted for treatment of alcoholrelated chronic pancreatitis with acute exacerbation. The acute episode was caused by a large impacted stone of 1.1cm in diameter within the proximal main pancreatic duct (●" Fig.1). Stricture of the duct downstream from the stone was noted on initial endoscopic retrograde cholangiopancreatography (ERCP) (●" Fig.2). A st...

Endoscopists are keenly aware of bleeding risks during and immediately after cystgastrostomy and reduce this risk by endoscopic ultrasound guidance to avoid manipulation near major vessels. Bleeding risk associated with cystgastrostomy stent removal after resolution of a pancreatic fluid collection, however, is less evident. We present our experience with bleeding during cystgastrostomy stent r...

Endoscopic placement of a single plastic stent (PS) to the main pancreatic duct (MPD) is awidely accepted treatment method for symptomatic strictures in patients with chronic pancreatitis [1,2]. Although adequate stent placement in the dominant stricture will relieve pain in the majority of patients [3–5], stents cannot be definitively removed in approximately one-third of patients because of p...
