Phytobezoar is a rare cause of gastro-intestinal tract obstruction. Common sites of phytobezoar are the stomach and small bowel. Naturally, extrahepatic duct phytobezoar is near impossible due to anatomical structure and location such as ampulla of vater, common bile duct and bifurcation of bile duct. Here, we present an extremely rare case of extrahepatic duct phytobezoar that resulted in abdo...

Exocrine and endocrine pancreatic function was studied in the rat after occlusion of the pancreatic ducts with acrylate or prolamine, respectively. After 5 months the effect of these procedures was a clear-cut exocrine insufficiency as evidenced by reduced enzyme activities in pancreatic tissue and in intestinal content, while the endocrine function was not impaired. The insulin secretory respo...

The purpose of this study was to compare histologic subtype and growth pattern, including invasion and intraductal spread to branch ducts, in main duct-type intraductal papillary-mucinous carcinoma (IPMC) by histopathology and immunohistochemistry. Five surgically resected samples of main duct-type IPMC from five patients, were studied. Main lesions, invasive components, and adjacent secondary ...

background: t ranscatheter closure of patent ductus arteriosus (pda) has become an alternative treatment to surgery. we evaluated the long-term results of the transcatheter closure of pda with the amplatzer duct occluder (ado) in children. methods: between may 2004 and october 2012, 138 children with pda (43 males and 95 females) underwent transcatheter pda closure. clinical, electrocardiograph...

Cysts whose walls reproduce completely or incompletely the structure of gut, whether discovered in the wall of the gut, attached to the gut, or even more or less remote from the gut, must have been derived from the gut (Evans, 1929). They originate either in the vitello-intestinal tract or in diverticula normally found in the developing embryonal entoderm (Lewis and Thyng, 1908). One or more of...

The nasopalatine duct (NPD) is a bilateral, epithelium-lined oronasal communication formed in the early fetal period. It connects the oral cavity with the nasal cavity within the primary palatal process. Mostly, the NPD obliterates during prenatal development and only epithelial remnants can be found after birth. A persistent NPD is therefore considered a developmental abnormality that often ex...

The association of a right aortic arch with an ipsilateral patent ductus arteriosus is rare, especially when there are no other intracardiac anomalies. We report three female patients aged 26, 35 and 9 years with this combination in whom previous attempts at surgical closure by thoracotomy and sternotomy were unsuccessful and who subsequently underwent successful percutaneous closure of the def...

Background: To investigate the effects of bile duct stricture on the pharmacokinetics of the immunosuppressant tacrolimus, the pharmacokinetics of tacrolimus in rats with bile duct ligation were evaluated and the effects of the amount of intestinal bile on intestinal tacrolimus absorption were determined. Methods: In vivo pharmacokinetic studies and in vitro metabolic studies in rats with bile ...
