Objectives

Narrative objectives1

To confirm whether the mucosa of incisura angularis belongs to fundic or pyloric gland region, we conducted a retrospective study which was additively designed to the previous prospective multicenter studies by the expert endoscopists and pathologists in Japan.

Number of participants that the trial has enrolled

270

Results

A total of 270 subjects were analyzed. The strictest criterion consists of serum antibody=<3.0 U/mL, endoscopic atrophy C-1 and histological grade 0 in all of the five items in Updated Sydney System. The numbers having fundic, transitional and pyloric mucosa at incisura angularis under the strictest criterion were 13 (50%), 13 (50%) and 0, respectively. The probability that the type of mucosa at incisura angularis would be pyloric was almost zero (97.5% confidence interval 0-0.132).

Endoscopic atrophy was diagnosed by visibility of the vascular pattern and rugal atrophy, and graded into 8 (C-0 to O-p). Five biopsy specimens were taken and histologically evaluated according to the Updated Sydney system. Gastric glands in incisura angularis (IA) were classified into three types: fundic, pyloric and transitional. Serum antibody to H. pylori was measured. We combined histological grading, endoscopic atrophy and serum antibody to diagnose non-infected normal stomach. We examined 5 criteria for diagnosing normal stomach, and evaluated gastric gland type of IA. In conclusion, the mucosal type of incisura angularis of normal stomach is either fundic or transitional, but not pyloric mucosa.
