A 9-Year Retained T-Tube Fragment Encased within a Stone as a Rare Cause of Jaundice
2008
Biliary diseases such as cholangitis may cause jaundice and liver damage. Here, we report on an unusual cause of jaundice in an 84-year-old man 9 years after cholecystectomy. Ultrasound analysis revealed unclear extrahepatic cholestasis and subsequent ERCP showed a large biliary stone sourrounding a T-tube fragment that had remained in the common bile duct for more than 9 years after surgery. The tip of the drainage and the stone could be successfully removed using Dormia baskets. This case suggests that plastic material accidentally left in the common bile duct favours the development of large biliary casts when present over long periods of time.
Management of retained bile duct stones: a prospective open trial comparing extracorporeal and intracorporeal lithotripsy.
1996
Abstract Background: Endoscopic management of common bile duct stones has become the approach of choice, especially in patients with high surgical risk. Problems are encountered if there are large stones or a duct stenosis. For these difficult stones, shock wave technology serves as an alternative to surgical intervention. Methods: A total of 125 patients with common bile duct stones in whom conventional endoscopic treatment had failed were selected and treated either by extracorporeal piezoelectric lithotripsy (ESWL, n=79) or intracorporeal electrohydraulic lithotripsy (EHL, n=46). The average age of our patients was 70 years. Results: In the ESWL group visualization of the stones by ultra…
Prospective, randomized, single-center trial comparing 3 different 10F plastic stents in malignant mid and distal bile duct strictures.
2003
Abstract Background: The aim of this study was to determine whether patency rates differ with respect to the material, design, and surface texture of 3 different plastic stents. Methods: A total of 120 patients (median age 70.5 years; interquartile range 62-78 years) with malignant mid or distal bile duct strictures, seen between March 1996 and May 1999, were prospectively randomized to receive a 10F polyurethane stent, a Teflon Tannenbaum stent, or a hydrophilic hydromer-coated polyurethane stent. The primary study outcome measure was the interval between stent insertion and the first episode of clogging (or the presence of jaundice at death without stent exchange). All 3 types of stent we…
Risk factors for extrahepatic biliary tract carcinoma in men: medical conditions and lifestyle: results from a European multicentre case-control stud…
2007
OBJECTIVES: To identify risk factors of carcinoma of the extrahepatic biliary tract in men. METHODS: Newly diagnosed and histologically confirmed patients, 35-70 years old, were interviewed between 1995 and 1997 in Denmark, Sweden, France, Germany and Italy. Population controls were frequency-matched by age and region. Adjusted odds ratios and 95%-confidence intervals were estimated by logistic regression. RESULTS: The analysis included 153 patients and 1421 controls. The participation proportion was 71% for patients and 61% for controls. Gallstone disease was corroborated as a risk factor for extrahepatic biliary tract carcinoma in men (odds ratio 2.49; 95% confidence interval 1.32-4.70), …
Mobile Communities in Developing Countries
2010
The number of mobile devices has exceeded four billions and is still growing. Especially in developing countries mobile devices are often the only access to Internet and digital services. In the most developed countries laptops, Wi-Fi and faster and faster wireless telecom networks have for long time made mobile access to various digital services possible while on the move. Still, large and instant mobile communities can only rely on more portable devices, such as mobile phones. In this paper we will analyze various mobile communities and the support they are offered by the social media sites. We will discuss the phenomena encountered in developing countries, like how the mobile technology …
PRICE CONVERGENCE IN THE EUROPEAN CAR MARKET
2008
International audience; This paper examines price convergence in the European Union car market over the period 1995-2005. We find that there is a clear evidence of price convergence among the EU15 countries, but not before 1999. Moreover, countries of the Economic and Monetary Union (EMU) started convergence previously to the EU15 as a whole. Finally, exchange rate changes have significantly contributed to price dispersion over time across countries. The results provide significant evidence that trade liberalization and the EMU have enhanced the process of regional integration in the European automobile industry, even though there is room for further measures to promote integration.
Marketing communication strategy of Finnish and Japanese mobile game developers and publishers
2017
Both the marketing communication strategy of mobile game industry and the industry itself have been drastically evolving in the past years since the development of computation, data transfer and communication technology on mobile devices. Marketing communication has been considered a significant part in marketing strategy, but the marketing communication strategy, activity and channels were not well investigated so far. In this study, 9 SMEs Finnish and Japanese mobile game developers and publishers provided their experience on how they built up marketing communication strategy for their targeting markets, which marketing communication channels they have used and how they chose the channels…
Positive and negative word of mouth (WOM) are not necessarily opposites: A reappraisal using the dual factor theory
2021
Prior research has not systematically investigated the enablers and inhibitors in conjunction to measure consumer behavior toward mobile wallets (m-wallets), focusing either on the adoption or the resistance perspective only. Similarly, antecedents and consequences of the dichotomous nature of word of mouth for m-wallets have also remained obscure so far. The present research proposes to address this void in the accumulated learnings by examining both enablers and inhibitors of mobile wallets (m-wallets) as antecedents of valence of word of mouth (positive and negative; PWOM and NWOM, respectively). Grounded in Dual Factor Theory, this study aims to explore consumers’ continued use intentio…
Message-driven factors influencing opening and forwarding of mobile advertising messages
2015
This work aims to analyse the influence of message-driven factors -informativeness, ubiquity, frequency and personalization- on consumer attitude and behaviour -opening and forwarding- towards mobile advertising messages. A theoretical model was developed and empirically tested using a sample of 355 Spanish teenager mobile users. Findings show that frequency is the dimension accounting the most -and significantly- of the four message-driven factors analysed on attitude toward mobile advertising. Attitude has a significant effect on acceptance of mobile advertising messages. Message-driven factors – in a direct way and indirectly through attitude toward mobile - lead to consumer opening and …
Understanding complaint channel usage in multichannel retailing
2019
Abstract This study aims to understand customer patterns of channel usage to voice complaints to multichannel retailers. Data were collected from multichannel shoppers for apparel in Spain by means of an online survey. Latent Class Analysis on complaint channel (store, website, mobile app and social media) usage was performed. The analysis identifies four customer segments that use complaint channels differently. Channel dependencies emerged, particularly related to mobile app usage. The study then explores how the identified patterns are related to channel usage for information search and purchase and to the quality of the relationship with the retailer. Results provide theoretical and man…
