Background Long-term maintenance of arterial duct patency by a catheter technique would be a valuable nonsurgical method of palliation for duct-dependent circulations. We used a new method: percutaneous radiofrequency thermal balloon angioplasty of neonatal lamb arterial ducts. Methods and Resuls Radiofrequency balloons 5 or 6 mm in diameter were introduced via the femoral vein of 32 neonatal l...

The routes of spread of pathogens into the pancreas in acute pancreatitis were investigated. Four experiments were performed: (1) cats with and without acute pancreatitis were given 10(7) Escherichia coli (E coli) intravenously, (2) in cats with acute pancreatitis 10(8) E coli was placed in the colon. In half of them the colon was then enclosed in an impermeable bag to prevent transmural spread...

Primary neuroendocrine carcinoma of the gallbladder is extremely rare because normal gallbladder mucosa does not contain neuroendocrine cells. Neuroendocrine cells can be detected at sites of intestinal metaplasia induced by chronic inflammation, which may be the initial step in the development of neuroendocrine tumor of the gallbladder. Anomalous union of the pancreaticobiliary duct (AUPBD) is...
