OBJECTIVE To evaluate the prognosis of different ways of drainage for patients with obstructive jaundice caused by hilar cholangiocarcinoma. MATERIALS AND METHODS During the period of January 2006- March 2012, percutaneous transhepatic catheter drainage (PTCD)/ percutaneous transhepatic biliary stenting (PTBS) were performed for 89 patients. According to percutaneous transhepatic cholangiogra...

OBJECTIVE The fundamental role of video-assisted thoracic surgery (VATS) in the treatment of spontaneous pneumothorax is generally acknowledged today. This study intends to evaluate whether VATS is justified at the onset of a first spontaneous pneumothorax through analysis of parameters tested on two group of patients treated respectively with pleural drainage and VATS. PATIENTS/METHODS The s...

Effective gas management is vital to the success of the longwall mining in the Bulli seam, in the Southern Coalfield, Sydney Basin, NSW, Australia. The evolution of gas drainage methods and practices are discussed with respect to gas type, gas drainage lead time and prevailing geological conditions. Both underground to inseam drilling and surface to inseam drilling techniques are described at b...

The difference between average pressures of two immiscible fluids is commonly assumed to be the same as macroscopic capillary pressure, which is considered to be a function of saturation only. However, under transient conditions, a dependence of this pressure difference on the time rate of saturation change has been observed by many researchers. This is commonly referred to as dynamic capillari...

global warming, as a consequence of greenhouse gases accumulation, has exerted significant impacts on biosphere. methane, a product of reduction processes of organic carbon in anaerobic conditions, is mainly emitted from paddy fields. the aim followed in this research is to evaluate the impact of midseason drainage on methane emission from paddy fields. the research was conducted with three tre...

This paper explores the use of graphics processing units (GPUs) for combined numerical analysis and visualization. Using an implementation of the O’Callaghan and Mark (1984) drainage accumulation algorithm, it explores the advantages and challenges that this environment brings to real-time, frame-by-frame production of spatial modeling products and their visualization. Modern GPUs employ massiv...

It is very difficult to define today the place of EUS-guided pancreatic duct drainage; in our experience, the best indication is anastomotic The development of interventional EUS has provided better access to the region of the pancreas. Just as pancreatic fluid collections, such as pseudocysts, can be successfully drained from the stomach or duodenum by endoscopic cystenterostomy or cystgastros...

Studies are on-going to establish the suitability of tire shreds in the landfill bottom drainage layer, to minimize clogging. Four experimental columns were constructed in which were 500 mm long and 200 mm in diameter. They were filled with different fillers and with a different amount of tire shreds. The most important problem with drainage filler in landfills is clogging. Over long periods of...

OBJECTIVE Published evidence indicates that surgical drainage of the pancreatic duct was more effective than endoscopic drainage for patients with chronic pancreatitis. This analysis assessed the cost-effectiveness of surgical versus endoscopic drainage in obstructive chronic pancreatitis. DESIGN This trial-based cost-utility analysis (ISRCTN04572410) was conducted from a UK National Health S...
