Special enema series
barium introduced to left colic flexure, then tip removed and patient evacuates,tip reinserted and barium introduced to sigmoid and air instilled, position altered to coat mucosa, spot radiographs taken as needed
closed system in which patient remains on table for entire procedure
does not require removal and reinsertion of enema tip
single stage closed system method
barium introduced by bag position, air introduced by bag inversion or by manual compression of sphygmoanometer bulb
