Gastritis Clinical Trial
Official title:
Reproducibility of Modified Lanza Scale for the Reporting of Gastritis and Duodenitis
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.
