Recurrent abdominal pain and upper gastrointestinal endoscopy findings in children and adolescents presenting at the Lagos University Teaching Hospital

INTRODUCTION: Recurrent abdominal pain (RAP) is a common reason for referral to the paediatric gastroenterology unit and the attending physician needs to be able to rule out an organic cause when evaluating any child with this condition. The aim of this study was to describe the endoscopic findings in children who presented to the paediatric gastroenterology unit of the Lagos University Teaching Hospital (LUTH) with RAP. METHODS: This was a prospective descriptive study which was conducted from January 2015 to July 2018 at the Paediatric Gastroenterology unit of the department of Paediatrics and the endoscopy unit of the LUTH, Lagos, Nigeria. All children and adolescents ≤ 19 years old with recurrent abdominal pain who were referred for upper GI endoscopy during the study period, were recruited. Baseline sociodemographic data, dyspepsia and alarm symptoms if present were documented. Results of other investigations namely stool examination for ova, parasites, occult blood and faecal antigen for Helicobacter pylori and abdominal scan were also documented. RESULTS: A total of 113 children with recurrent abdominal pain was referred during the study period and 87 (76.7%) of them had upper GI endoscopy done. Out of the participants, 38(43.7%) were boys and 49(56.3) girls. Alarm features were present in 15(17.6%) and dyspepsia was seen in 22(25.3%) of the subjects. The main endoscopic findings were: gastritis in 39 (44.8%), gastric erosions in 14(16.2%), hiatus hernia in 7(8.1%), duodenitis in 6 (6.9%), gastric polyp in 4 (4.6%). CONCLUSION: Upper GI endoscopy remains an invaluable tool in the tool in evaluating RAP in children as it enables accurate diagnosis of GI causes of RAP. There is a need to advocate for easier access to this procedure in the developing countries.
