Comprehensiveness

On this resource, the following formatting is used for comprehensiveness:

  • Minimal depth
  • (Moderate depth)
  • ((Comprehensive))

Microscopic evaluation

Generally screen for:

  • Gastric adenomas and adenocarcinomas. Further information: Stomach tumor

Microscopy report

Example in case of normal findings:

(Stomach, biopsy:) Gastric (oxyntic/antral) mucosa without significant histopathologic changes.
(Negative for Helicobacter ((pylori)) organisms on H&E slide.)
