BACKGROUND Acute cholecystitis can be the result of retention of bile in the gallbladder with possible secondary infection and ischaemia. The aim of the present study was to investigate whether internal drainage of the gallbladder could protect against the development of acute cholecystitis in a pig model. MATERIALS AND METHODS Twenty pigs were randomized to either internal drainage (drained)...

Crystalline pipe plugging in tunnel drainage systems is one of the causes lining cracking and water leakage. Therefore, effective prevention crystalline blockage very important to ensure safety stability structure during operation. Combined with theories fluid mechanics, structural mechanics basic physics, flocking anti-blocking mechanism was comprehensively analyzed by using method mathematica...

The anatomical and functional status of the epifascial and subfascial lymphatic compartments was analyzed using two compartment lymphoscintigraphy in five groups of patients (total 55) with various forms of edema of the lower extremities. Digital whole body scintigraphy enabled semiquantitative estimation of radiotracer transport with comparison of lymphatic drainage between those individuals w...

In the process of tunnel construction, water inrush disaster is one main engineering geological disasters. karst strata, different types water-bearing structures or bodies develop and occur in soluble rock layer, excavation easily forms new drainage channels, resulting tunnel. Based on project Huali Highway Banyanzi Tunnel, this paper studies characteristics, mechanism, treatment measures Accor...

This report summarizes the results of 64 percutaneous catheter drainage of abdominal abscesses and fluid collections in 56 patients. Aspiration and drainage was guided with computed tomography in 34 patients and with ultrasound in 30 patients. Success rate was 90%. Infected collections were successfully drained in 94% and noninfected collections in 72% . Partial success was achieved in two...

Second, we believe that to compare the two surgical techniques, there must be a certain consistency in the two study groups. The authors only indicate the age and sex distribution of both groups, however it is very important to know several things that make the series are not significantly homogeneous and therefore the results may be biased. It is important to know that the degree of clinical s...

An automated process for the delineation of drainage basins, using as input only the vector based drainage network, is described which provides an alternative to DEM based methods. The procedure involves an approximation of the line Voronoi diagram for the network using a constrained Delaunay triangulation of the network's Planar Straight Line Graph. The constrained triangulation, which include...

Primary pneumatization of the frontal bone occurs in first year life, but further continues until 18 years age. Elongation ethmoidal infundibulum and recess, or upwards migration anterior cells has been proposed as a mechanism sinus development. The drainage pathway is displaced posterior direction depending on pattern frontoethmoidal cells. Also, sinuses can be connected to directly middle mea...
