[The changes of gastric diseases during the past twenty five years].

OBJECTIVES

To study the changes of duodenal ulcer, gastric ulcer, gastric cancer and Helicobacter pylori (Hp) infectious status, according to the clinical data of endoscopy in our hospital during the past 25 years.

METHODS

The patients with duodenal ulcer, gastric ulcer and gastric cancer diagnosed by endoscopy and pathology had been selected, 104 987 general endoscope cases during the period from Jan. 1980 to Dec. 2004. The general cases were divided into 8 age groups as follows: 10-< 20 years old, 20-< 30 years old, 30-< 40 years old, 40-< 50 years old, 50-< 60 years old, 60-< 70 years old, 70-< 80 years old and > or = 80 years old.

RESULTS

The average detected rate of duodenal ulcer, gastric ulcer, and gastric cancer are 13.03%, 4.19% and 1.68% respectively. The detected rate of gastric ulcer was decreased after 1996. The detected rate of duodenal ulcer was decreased after 1999. The gastric cancer detected rate fluctuate between 1.02% and 2.36%. The average ages of duodenal ulcer, gastric ulcer and gastric cancer are 41.8, 50.7 and 59.4 respectively. The tendency of average age shows ascendant. In all patients, the detected rate of Hp showed slightly descendent after 1999.

CONCLUSIONS

The diagnostic age of duodenal ulcer, gastric ulcer and gastric cancer shows ascendant tendency; The detected rates of duodenal ulcer, gastric ulcer show descendent tendency; There is no apparent change in the detected rate of gastric cancer. The Hp detected rate shows descendent tendency slightly.
