Direct examination of Helicobacter pylori

Direct examination of Helicobacter pylori refers to the detection of Helicobacter pylori by direct smear, staining, tissue section staining and bacterial culture by gastroscopic examination of gastric mucosa (mostly gastric antrum mucosa). The doctor inserted a 1 meter long biopsy forceps from a dedicated tunnel in the body of the gastroscope. The size of the jaws has been carefully studied and can only be bitten into the gastric mucosa without significant damage to the stomach wall. The doctor in the pathology department cuts the tissue block into thinner sections, and then processes the pathological slides that are seen by dyeing, and then observes the presence or absence of Helicobacter pylori characteristics by microscopy. Basic Information Specialist classification: Digestive examination classification: endoscope Applicable gender: whether men and women apply fasting: fasting Tips: Not suitable for the crowd: poor coagulation. Normal value No Helicobacter pylori was observed. Clinical significance Abnormal results H. pylori was observed to be a unipolar, multi-flagellate, blunt-ended, spiral-curved bacterium.

The size of the jaws has been carefully studied and can only be bitten into the gastric mucosa without significant damage to the stomach wall. In order to make the diagnosis more accurate, it may take more than two tissues and store them in a small glass bottle containing the preservation solution. The doctor in the pathology department cuts the tissue block into thinner sections, and then processes the pathological slides that are seen by dyeing, and then observes the presence or absence of Helicobacter pylori characteristics by microscopy.
