title: Antral gastritis caused by Helicobacter pylori infection in the pediatric age group is associated with increased mesenteric lymph node dimension observed by ultrasonography.
abstract: BACKGROUND
  To find out if transabdominal ultrasonography (US) may have a predictive role for detection of antral gastritis and Helicobacter pylori (HP) infection in the antrum of pediatric age group.
  
  
  METHODS
  A total of 91 (63.6%) patients and 52 (36.4%) controls were allocated into two groups as follows: Group 1 (n=91): patients with complaints and endoscopic findings consistent with gastritis and documented HP infection; Group 2 (n=52): patients with complaints and endoscopic findings consistent with gastritis in the absence of documented HP infection. These two groups were compared in terms of demographics and biggest mesenteric lymph node detected, muscularis mucosa thickness, submucosal thickness, muscularis propria thickness, and total gastric wall thickness.
  
  
  RESULTS
  The two groups exhibited no statistically significant difference with respect to age (P=0.747), and presenting symptoms (P=0.982). However, the mesenteric lymph node dimension was significantly increased in Group 1 (P=0.039). Median mesenteric lymph node dimension was 12.9 (±15.4) mm in Group 1, while 11.0 (±12.8) mm in Group 2. No significant difference was observed between groups in terms of muscularis mucosa thickness (P=0.243), submucosal thickness (P=0.174), muscularis propria thickness (P=0.356), and total gastric wall thickness (P=0.223).
  
  
  CONCLUSIONS
  Antral gastritis caused by HP infection in the pediatric age group is associated with increased mesenteric lymph node dimension observed by US.
