    Background: Colonoscopy is a well established diagnostic and therapeutic procedure in pediatrics. Aim: To evaluate colon preparation alternatives for colonoscopy or sigmoidoscopy, type of sedation, clinical indications and findings. Patients and methods: Prospective study of 123 children referred for colonoscopy. Demographic data, type of colon preparation, sedation, type of endoscope and endoscopic results were obtained. The following day, a phone interview was carried out inquiring about duration, quality and adverse effects of the sedation and procedure. Results: Seventy one boys (58%) and 52 girls (42%) with a mean age of 6.7±4.4 years, were recruited. The main indication was lower gastrointestinal bleeding (71%). The different colon preparations produced elimination of clear liquid stools in 50%, non transparent liquid in 23%, semi liquid in 22% and solid in 6% of the patients. Most common side effects were abdominal distension (20%) and nausea (16.8%). The most commonly used drugs were midazolam (76%) and demerol (43%). The average duration of the procedure was 18.3 minutes (range: 4-50). The most common findings were rectal polyps (18.7%) and hemorrhagic colitis (14.6%). In 77% of cases, the sedation was considered very good or good. Colon visualization was described as very good (51%) or good (36%). Seventy three percent of children had complete amnesia. The most common adverse effect was vomiting (7.5%). Conclusion: Lower endoscopies are feasible procedures to carry out in children, in an ambulatory basis, with intravenous sedation and minimum adverse effects.
