Magnetic continent colostomy device.
For patients, the principal drawback of a colostomy is the loss of faecal continence. To achieve a continent colostomy has long been the goal of surgeons. A magnetic stoma seal became feasible when a strong, light, durable magnet made of samarium-cobalt became commercially available in 1972. This metal compound has the highest magnetic energy per unit volume and loses only a few per cent of its...
متن کاملContinent colostomy by means of a new one-piece disposable device. Preliminary report.
A study was established concerning a continent colostomy system consisting of a new one-piece disposable plug. Twenty patients participated: 13 men and 7 women, who ranged in age from 35 to 87 years. All patients had an end colostomy located on the left lower quadrant. The colostomy age ranged from 2 months to 7 years. Of the 20 participants, 17 found the new procedure to be safer and more comf...
متن کاملMagnetotelluric Studies of Active Continent–Continent Collisions
Continent–continent collisions are an important tectonic process and have played a fundamental role in the evolution of the modern continents. A combination of geological and geophysical data has provided new constraints on the structure and temporal evolution of these orogens. Magnetotelluric (MT) studies have been an important part of these studies since they can constrain the fluid content a...
متن کاملDiarrhoea after continent ileostomy.
To determine the nature and frequency of malabsorption in patients with continent ileostomies, faeces and urine from 42 patients with ileal pouches and from 19 patients with conventional ileostomies were analysed and compared. The patients with conventional ileostomy were matched with patients with ileal pouches. Thirteen of the patients with pouches were found to have excessive faecal volumes ...
متن کاملA Stratospheric "Drain over the Maritime Continent
Operational wind data are used to show that the time-averaged mass flux near the tropopause is downward over the maritime continent (Indonesia) region during both summer and winter. The air descends within a layer above the convective level of neutral buoyancy (despite mean upward motion below and above this layer) and must rise through the mean tropopause elsewhere, contradicting the common vi...
