We report a case of a 70-year-old man with acute acalculous cholecystitis caused by Giardia lamblia. Contrast-enhanced computed tomography (CT) showed distention of the gallbladder due to a pericholecystic abscess without gallstones. Magnetic resonance cholangiopancreatography and drip infusion cholecystocholangiography-CT demonstrated a stricture of the hilar bile duct and cystic duct obstruct...

We describe here a case of intraductal tubular carcinoma of the main pancreatic duct. Gadolinium-enhanced pancreas magnetic resonance (MR) imaging showed an enhancing mass that was confined in the dilated main pancreatic duct of the pancreatic body, along with dilatation of the upstream main pancreatic duct and chronic pancreatitis that was due to obstruction. MR cholangiopancreatography and an...

884 CMAJ, May 15, 2012, 184(8) © 2012 Canadian Medical Association or its licensors Gallstone disease is responsible for about 1.8 million ambulatory care visits and more than 700 000 cholecystectomies yearly in the United States. In Canada, the adjusted annual rate of elective cholecystectomy was 260.8 per 100 000 population during the period 1992–2000. Gallstone disease is the second most com...

UNLABELLED The aim this study was to analyse our management bile duct injuries following laparoscopic cholecystectomy. PATIENTS AND METHODS This prospective-retrospective study presents six cases of major bile duct injuries that occurred in our first 1000 laparoscopic cholecystectomies. Neuhaus et al. classification was used in this study. RESULTS Bile duct injuries following laparoscopic c...

Vertebrate kidney tissue exhibits variable morphology that in general increases in complexity when moving from anterior to posterior along the body axis. The nephric duct, a simple unbranched epithelial tube, is derived in the avian embryo from a rudiment located in the anterior intermediate mesoderm (IM) adjacent to somites 8 to 10. Using quail-chick chimeric embryos, the current study finds t...

INTRODUCTION Mixed adenoneuroendocrine carcinomas (MANECs) of the distal bile duct are extremely rare, and only a few cases have been reported in the English literature. PRESENTATION OF CASE An 82-year-old man was referred to our hospital for increasing biliary enzymes. Abdominal computed tomography (CT) showed enlargement of the intrahepatic bile ducts and stenosis of the distal bile duct. E...

BACKGROUND Biliary duct injury (BDI) is one of the most common complications in laparoscopic cholectecystomy (LC), in this study, we have tried to place an illuminating optical fiber via endoscopy in the CBD during LC, the biliary duct anatomy can be clearly delineated, thus CBD injury is avoided. METHODS Sixteen patients with chronic cholecystitis or/and cholelithiasis from February 2007 to ...

A 73-year-old woman was admitted because of obstructive jaundice. Computed tomography revealed a stricture in the lower bile duct with enhanced bile duct wall. Endoscopic retrograde cholangiopancreatography (ERCP) revealed a tapering stenosis at the lower bile duct. Transpapillary histological biopsy using biopsy forceps through ERCP was performed; the diagnosis of signet ring cell carcinoma (S...

BACKGROUND Nitric oxide is a potent dilator of the pulmonary vasculature. There have been no previous reports on the action of nitric oxide on the arterial duct. OBJECTIVES To determine the responses of isolated post-term arterial duct rings from lambs to oxygen, prostaglandin E2 (PGE2) and the nitric oxide donor, 3-morpholinosydnonimine (SIN-1). SETTING Experimental laboratory. SUBJECTS ...

cystic duct and stone removal were performed under a preoperative diagnosis of chronic cholecystitis (adenomyomatosis) and stone-induced dilated cystic duct. Macroscopically, the gallbladder showed chronic cholecystitis with segmental adenomyomatosis ( fig. 2 ). The cystic duct retained the spiral valve, but was significantly dilated with wall thickening. Histopathologically, chronic cholecysti...
