AB Gastritis  is  an  inflammatory  process  associated  with  gastric  mucosal  injury.  It  is  usually  classified  by  histologic  features  (atrophic  or  non-atrophic,  chemical,  granulomatous,  eosinophilic,  lymphocytic,  etc.),  time  course  (acute  versus  chronic),  etiology  (Helicobacter  pylori,  bile,  non-steroidal  anti-inflammatory  drugs  (NSAIDs),  Crohn’s  disease,  etc.),  and  proposed  pathophysiology.  Peptic  ulcers  are  deep  mucosal  ulcerations  that  penetrate  into  the  muscularis  mucosa  of  the  stomach  or  duodenum.  Peptic  erosions  are  superficial  mucosal  lesions;  they  do  not  involve  the  muscularis  mucosa.  Peptic  ulcers  and  erosions  are  relatively  uncommon  in  children,  found  in  less  than  25%  of  children  undergoing  upper  gastrointestinal  endoscopy  for  abdominal  pain.1H.  pylori  is  by  far  the  most  common  etiology  for  gastritis  and  peptic  ulcer  disease  (PUD)  in  the  pediatric  age  group.
