Is a Reporting System for Gastritis or Duodenitis (Modified Lanza Scale) Reproducible?
The modified Lanza scale (Lanza FL, 1984) has been widely utilized to grade the degree of gastritis and duodenitis. However, the inter-rater or intra-rater reproducibility of this scale has never been validated. As a quality improvement program, it is important to study the reproducibility of the scale between different operators and the operators himself.
Method: During upper endoscopic examinations, one investigator performed the procedure and the second investigator look at the endoscopic image. The degree of gastritis and duodenitis is graded. The results of the grading are blinded to the other investigator.
The endoscopic video is stored for reassessment to determine the intra-rater reliability. The patient identifier is stored in serial number. The investigator will not retrieve the report of the first assessment during the second assessment.

Medical and Biotech [MESH] Definitions
GASTRITIS with atrophy of the GASTRIC MUCOSA, the GASTRIC PARIETAL CELLS, and the mucosal glands leading to ACHLORHYDRIA. Atrophic gastritis usually progresses from chronic gastritis.
GASTRITIS with HYPERTROPHY of the GASTRIC MUCOSA. It is characterized by giant gastric folds, diminished acid secretion, excessive MUCUS secretion, and HYPOPROTEINEMIA. Symptoms include VOMITING; DIARRHEA; and WEIGHT LOSS.
Inflammation of the GASTRIC MUCOSA, a lesion observed in a number of unrelated disorders.
A vitamin found in green vegetables. It is used in the treatment of peptic ulcers, colitis, and gastritis and has an effect on secretory, acid-forming, and enzymatic functions of the intestinal tract.
A species of HELICOBACTER that colonizes in the STOMACH of laboratory MICE; CATS; and DOGS. It is associated with lymphoid follicular hyperplasia and mild GASTRITIS in CATS.
