[Feasibility of methods of outpatient preparation for proctologic examination. Comparison of phosphate and sorbit enemas in a randomized double-blind study].

Phosphate and sorbite enemas for preparing a patient for rectoscopy and flexible endoscopy were compared in a randomised double-blind study on 60 patients. Side effects were low and equally rare in both groups of patients. There was no statistically significant difference in the cleansing quality of both enemas. Phosphate enemas produced reliable onset of action in a significantly shorter time, and the cleansing depth was also significantly better.
