External Biliary Fistula
We report 210 cases of external biliary fistula treated in our clinics between 1970–1992. In 7 cases, fistulas were formed after iatrogenic bile duct injury, in 4 cases after exploration of common bile duct, in 4 cases due to disruption of biliary-intestinal anastomosis, and in 2 cases due to liver trauma. In 85 cases bile leak was observed after cholecystomy, in 103 cases after hydatid disease surgery, and in 4 cases after the passage of P.T.C. catheter. In one patient the appearance of the fistula was due to spontaneous discharge of a gallbladder empyema. 173 cases were managed conservatively, and 37 cases surgically
Intrabiliary rupture of liver hydatid cyst: a case report and review of the literature
Herein, we report a 66 year old woman who was diagnosed to have intrabiliary rupture of liver hydatid cyst with demonstrative computed tomography, magnetic resonance imaging, and magnetic resonance cholangiopancreatography findings, with a review of the literature
Formalin-induced experimental sclerosing cholangitis in the rat
The few reported cases of sclerosing
cholangitis following removal of an echinococcus cyst are
thought to be a consequence of the chemical action of
formalin used for sterilization of the residual cavity. The
aim of this study was to assess this hypothesis.
We injected 0.15ml of 2% buffered formalin solution
into the central hepatic lobe of five rats, after a midline
laparotomy. At 6, 12, 18 and 24 weeks after formalin
injection al1 rats were reoperated upon and a sample of
hepatic parenchyma from both the central and the left
hepatic lobe was obtained for microscopic evaluation.
Our findings, dilatation of portal tracts and bile
canaliculi, thickening of the pericanalicular cytoplasm,
portal and periportal inflammatory cell infiltration and
fibrosis and enlargement of the perisinusoidal space of
Disse, suggest that 2% formalin solution leads to the
development of essential phenomena of cholestasis and
sclerosing cholangitis in the rat, so thus it should be
avoided in liver hydatid disease surgery
Federation of internet of things testbeds for the realization of a semantically-enabled multi-domain data marketplace
The Internet of Things (IoT) concept has attracted a lot of attention from the research and innovation community for a number of years already. One of the key drivers for this hype towards the IoT is its applicability to a plethora of different application domains. However, infrastructures enabling experimental assessment of IoT solutions are scarce. Being able to test and assess the behavior and the performance of any piece of technology (i.e., protocol, algorithm, application, service, etc.) under real-world circumstances is of utmost importance to increase the acceptance and reduce the time to market of these innovative developments. This paper describes the federation of eleven IoT deployments from heterogeneous application domains (e.g., smart cities, maritime, smart building, crowd-sensing, smart grid, etc.) with over 10,000 IoT devices overall which produce hundreds of thousands of observations per day. The paper summarizes the resources that are made available through a cloud-based platform. The main contributions from this paper are twofold. In the one hand, the insightful summary of the federated data resources are relevant to the experimenters that might be seeking for an experimental infrastructure to assess their innovations. On the other hand, the identification of the challenges met during the testbed integration process, as well as the mitigation strategies that have been implemented to face them, are of interest for testbed providers that can be considering to join the federation. © 2018 by the authors.
