Histopathological study of gastrointestinal endoscopic biopsies in pediatric patients

Abstract

Abstract Background Non neoplastic GI lesions in pediatrics are variable and differ in types and prevalence among each pediatric age group. Helicobacter pylori is an important pathogen that can cause gastritis and peptic ulcers in adults as well as in children. Celiac disease is a gluten-dependent autoimmune disorder which affects individuals having genetic susceptibility. Eosinophilic gastrointestinal diseases are disorders that primarily affect the gastrointestinal tract with eosinophil-rich inflammation in the absence of known causes for eosinophilia. Inflammatory bowel disease (IBD) is a chronic inflammatory disorder, mainly affecting the gastrointestinal tract with extraintestinal manifestations and associated immune disorders. It seems that it is one of the most common gastrointestinal diseases affecting children in the developed countries. Aim of the work To study different types of paediatric non neoplastic gastrointestinal lesions from gastrointestinal endoscopic biopsies received at the Pathology Department in Ain Shams University hospital during a period of 2 years (2017-2018), and to correlate them with the clinicopathological presentations and endoscopic findings. Patients and Methods A cross sectional study was conducted on all pediatric gastrointestinal biopsies received at Pathology Department in Ain Shams University Hospital during the period of two years (2017- 2018). Only cases with information for all the covariates (n = 580) were selected and the results were statistically analyzed. Results Total 580 pediatric cases were enrolled according to inclusion criteria. Nonspecific gastrointestinal inflammation represented (47.1%), Helicobacter pylori associated gastrointestinal inflammation represented (43.5%), Eosinophilic gastrointestinal disease represented (3.8%), Inflammatory bowel disease (IBD) represented (3.7%), Celiac disease represented (1.9%). Conclusion This is the first study conducted in Ain Shams University Hospitals to assess the different types of pediatric non neoplastic gastrointestinal lesions received with clinicopathological and endoscopic correlation. The most common pediatric non neoplastic GI lesion is Helicobacter pylori infection. The diagnosis of pediatric non neoplastic GI disorder necessitates interdepartmental teamwork between GI pediatricians and pathologists.
