[Orthograde intestinal lavage in the preparation for colonoscopy]

Thirty-eight proctological patients were prepared for colonoscopy by drinking 2l of aqueous solution of polyethylene glycol-4000 and electrolytes, so that additional purgatives, cleansing enemas, and waste-free diet are not needed. Control of hemodynamics, clinical and biochemical blood tests, and plasma electrolyte content revealed no significant changes in these parameters after preparation for the examination. Colonoscopy was conducted to a full measure in 94% of cases. This method was preferred rather than the use of purgatives and enemas by 82% of patients. Intestinal lavage with polyethylene glycol and electrolyte solution is a simple and effective method, it is convenient for the patient and does not cause marked side effects.
