Hilar cholangiocarcinoma has an extremely poor prognosis and is usually diagnosed at an advanced stage. Palliative management plays an important role in the treatment of patients with inoperable hilar cholangiocarcinoma. Surgical, percutaneous, and endoscopic biliary drainage are three modalities available to resolve obstructive jaundice. Plastic stents were widely used in the past; however, se...

BACKGROUND We present a case to illustrate controversies in percutaneous drainage of infected, perinephric haematoma in a tetraplegic patient, who had implantation of baclofen pump in anterior abdominal wall on the same side as perinephric haematoma. CASE PRESENTATION A 56-year-old male with C-4 tetraplegia had undergone implantation of programmable pump in the anterior abdominal wall for int...

From 1978 to 1985 96 patients with their first spontaneous pneumothorax were randomised into three groups, receiving either treatment with simple drainage (34 patients), drainage with tetracycline pleurodesis (33 patients), or drainage with talc pleurodesis (29 patients). There were 58 men and 38 women, aged 18-88 years. There was no significant difference between the three groups in the mean t...

In these notes on drainage design procedure, three drain spacing formulae are considered suitable for designing sub-surface drainage systems. The Hooghoudt and the Kirkham-Toksoz formulae have been developed for steady state conditions and the Glover formula is applicable to the transient state condition. The steady state condition implies that the surface inflow is equal to the outflow through...

However, we have reservations regarding the routine use of central venous catheters to drain pleural effusions. Several manufacturers (including the Sims-Portex Seldinger Chest Drainage Kit and Cook Quick-Thal Chest Tube) have specific chest drainage systems that take advantage of the Seldinger dilator over a wire method of insertion. These have the advantage of having a number of side ports (t...

introduction: better use of water and soil resources in paddy fields, increase in rice production and farmer's income, installation of subsurface drainage system is necessary. the main goalof these systems, are aeration conditions improvement prevention of water logging, yield increase, land use increase and multiuse of the land. in different countries, installation of subsurface drainage cause...

gully erosion has an important role in fars province due to sediment production and enormous damages to land, roads and infrastructures. in this research, 15 gullies were selected to measure their morphometric characteristics. the length, depth, top and bottom width and volume of gully erosion were then measured. influential factors on the sediment production and gully development were analyzed...
