OBJECTIVE: The objective of this study is to analyze risks factors of morbidity on colonoscopy. METHOD: From March to June of 2009, 170 patients were examined and analyzed prospectively. Risks factors as age, sex, indication of exam, ambulatory or hospital exam, adverse events and quality of intestinal preparation, endoscopic procedure, diagnoses and incident before, during or after procedure were analyzed. RESULTS: The average age was 60,16±14,69 years old, with majority of female. The prevalent indication of exam was post-operative. Three exams were inconclusive due to bad colonic preparation. From the rest, 36,53% were normal exams and the majority of the abnormal ones were polyps, adenomatous predominantly. In relation of morbidities, 48,82% of patients present some morbidity, Arterial Hypertension as the most common. Only 22,94% of patients have been some adverse event with the intestinal preparation. Colonic preparation was clean on 65,88% of exams and when compared with morbidity there were significant relation. Other significant factor was the presence of endoscopic procedures (44,7% of exams), the majority polypectomies. Morbidity was 16,47%, with dehydration more prevalent. There was no mortality. CONCLUSION: Quality of intestinal preparation and endoscopic procedures are factors directed related with colonoscopy morbidity.
