Radiopaque Short Pancreatic Stents Reliably Migrate in Nearly All Patients When Inserted for Prevention of Pancreatitis.

Placement of a pancreatic duct (PD) stent for prevention of post-endoscopic retrograde cholangiopancreatography (ERCP) pancreatitis (PEP) often necessitates a second procedure for stent removal, generally within 2-4 weeks to avoid stent occlusion or injury to the duct. These procedures are associated with increased costs and may result in procedure-related complications. Stents without internal anchoring flaps were developed to allow spontaneous migration into the duodenum, thus obviating the need for a repeat procedure.

Acute Mesenteric Ischemia Caused by Rare Cardiac Tumor Embolus.

Acute mesenteric ischemia (AMI) is a rare vascular emergency associated with a high mortality rate. The most common cause of AMI is cardiac emboli from thrombi associated with atrial fibrillation or following myocardial infarction. We present a case of AMI caused by a unique source of emboli, confirmed as an embolization of a cardiac sarcoma to the small bowel by matching biopsies obtained from the superior mesenteric artery (SMA) and the embolic source.

Multidisciplinary diagnostic and therapeutic approaches to pancreatic cystic lesions.

Pancreatic cystic lesions are commonly encountered today with the routine use of cross-sectional imaging modalities such as computed tomography (CT) and magnetic resonance imaging (MRI). The majority of patients discovered to have a pancreatic cyst are completely asymptomatic; yet the presence of such a finding instills fear in the minds of both patient and physician, as the concern for malignant transformation to pancreatic cancer is great despite the relatively low overall likelihood of cyst progression. Not all cysts in the pancreas represent pancreatic cystic neoplasms (PCNs), and not all PCNs have significant malignant potential.
