[Intestinal preparation for colon enema with fleet sodium phosphate: comparative study with the conventional method].
OBJECTIVE
To evaluate the possible optimization of a well-tolerated and versatile method of intestinal preparation able to adequately free the lumen and consequently improve diagnostic results with a lower risk of prolonged hospital stay for incorrectly prepared patients.


METHODS
We examined 40 patients, namely 20 men (mean age 70 years, range 52-87) and 20 women (mean age 68 years, range 49-81) referred to the Institute of Radiology of the Università Cattolica del Sacro Cuore, Gastrointestinal tract Unit, to undergo double contrast colonic enema. The patients were divided into two groups by one-to-one randomization: group 1 was prepared with the conventional method and group 2 with the new protocol for intestinal preparation. On the two days before the examination a low-residue diet was administered; the day before the examination a phial of Fosfo-soda fleet was administered in two times (at 8 am and 4.30 pm), which was diluted with half a glass of water. Bread, pasta and vegetables were strictly forbidden at lunch and soup or milk at supper; the patients were fasted on the examination day. Two evaluations were performed: one to assess tolerance to the preparation and the other, a radiographic study, to assess the grade of intestinal preparation, the presence of secretions/bubbles, and the degree of painting.


RESULTS
Of the 20 patients given X-prep, 3 had to discontinue it and 4 exhibited severe side-effects, but completed the treatment; tolerance was satisfactory in the remaining 13 patients. The grade of intestinal preparation, the presence of secretions/bubbles, and the degree of painting were considered satisfactory in 9, 17 and 16 patients respectively. None of the patients given Fosfo-soda fleet had to discontinue it and tolerance was satisfactory in 19 patients. The grade of intestinal preparation, the presence of secretions/bubbles, and the degree of painting were considered satisfactory in 15, 18 and 18 patients respectively. The statistical analysis of all data was performed with Wilcoxon test.


CONCLUSIONS
Intestinal preparation with Fosfo-soda fleet appeared to be definitely better than the conventional method relative to tolerance (p = .02, a statistically significant difference), while providing similarly satisfactory data relative to the other parameters.


CONCLUSIONS
Our results, coupled with the versatility of Fosfo-soda fleet (possible application in colonoscopy) and its ease of use recommend this preparation not only for inpatients but also for outpatients in whom self-administration is feasible.
