[Bowel preparation for colonoscopy with sodium picosulphate and magnesium citrate in children and adolescents]. / Preparo intestinal para colonoscopia com picossulfato sódico e citrato de magnésio em crianças e adolescentes.

BACKGROUND: The efficacy of colonoscopic examination depends directly on bowel cleansing preparation. There are few studies in the medical literature about bowel preparation in children. AIM: To determinate the efficacy of picosulphate sodium with magnesium citrate as a bowel preparation in children and adolescents. PATIENTS AND METHODS: In an open prospective and consecutive trial, we included all children above 1 year of age submitted to colonoscopy for different indications. All patients received the drug the day before the procedure and was allowed no solid food but a liberal intake of clear fluids. The adequacy of the preparation was graded as follows: gI--excellent, gII--good, gIII--fair and gIV--poor. RESULTS: Forty-six patients were included. The age ranged from 12 months to 16.1 years (median = 6.6y), 54.3% were males. Bowel preparation was made according to instructions in 37/46 (80.4%) of patients, 9 patients did not adhere to diet of clear liquids and 22/46 (47.8%) had side effects. The adequacy of the bowel preparation was: gI in 41.3%, gII in 52.2%, gIII in 6.5% and none in gIV. CONCLUSION: Bowel preparation with picosulphate sodium and clear fluids provides an effective, practical method of preparing the bowel for colonoscopy in children and adolescents and could be recommended.
