[Simple and efficient cleansing of the large intestine for colonic radiography].

A clinical trial documented the excellent cleansing effect of a single low dose of the oral laxative sodium picosulphate. To achieve good preparation of the colon it is essential to ensure a combined regimen including simple diatary restrictions and liberal fluid intake during the two days preceding the radiological examination. An additional mechanical washout lavage is time-consuming and uncomfortable, and usually unnecessary for outpatients.
