ABSTRACT
In recent years, along with advancement in medical technology including endoscopic techniques have played an important role in the etiology of recurrent abdominal pain [RAP]. The aim of this study was to evaluate the role of upper endoscopy and gastrointestinal biopsy in the children with RAP. This cross sectional study took place in Zahedan [IRAN] in 2005- 2007. Chronic abdominal pain was defined as three episodes of pain occurring in a period of 3 consecutive months with a severity in routine functioning. After taking history and physical examination, patients underwent upper endoscopy. Sections of biopsy were evaluated by a pathologist. Informed consent was taken. Then, data were gathered and analyzed with SPSS. From 80 children in this study, 58 cases had gastritis [22 cases with HP gastroduodenitis], 13 cases had esoghagogastritis and 23 cases had chronic nonspecific gastritis. Celiac disease in 5 cases and normal results in 3 cases were found. The most remarkable symptom was night abdominal pain [52%].Upper endoscopy has an important role in finding etiologies in children with RAP
