Introduction: Chronic abdominal pain occurs on a frequent basis and interferes with the quality of life of the child; know its true prevalence in the consultation helps to improve the diagnostic approach and clarify the organic or functional cause to indicate specific treatment. Objective: determine the prevalence of organic and functional chronic abdominal pain in gastroenterology consultation. Patients and methods: A descriptive, retrospective and longitudinal study (January 2014-March 2015). Defintion of chronic abdominal pain, organic and functional. Rome III criteria. Variables: age, sex, clinical features, laboratory, ultrasound and upper endoscopy. Results: 137 children with chronic abdominal pain of a total of 1194 patients evaluated, for an overall prevalence in the consultation of 11.45% (99% CI: 9.10 to 13.85). Average age 9.8 years (range 4-19), 56.20% female and 43.8% male; the most affected age group 10-15. Upper endoscopy was performed at 64.96%, an abdominal ultrasound was altered in 11.67%. Abdominal pain of organic origin was found in 92/137 (67.15%) for a real prevalence of 7.71% (99% CI: 5.72 to 9.69), causes: gastroduodenitis with or without Helicobacter pylori infection 71/92 (77.17%), allergic enteropathyn  12/92 (13.04%), parasitosis 5/92 (5.43%), other causes 4/92 (4.36%). Functional abdominal pain 45/137 (32.85%) with a prevalence 3.77% (IC99%: 2.32 to 5.19), the most frequent was constipation, 30/45 (66.66%), dyspepsia 8/45 (17.78%) and irritable bowel syndrome 7/45 (15.56%). Conclusions: chronic abdominal pain is a significant prevalence in the consultation, the organic cause was more common than functional, and use of clear definitions allowed for better patient assessment, identify the cause and indicate the specific treatment.
