Objective To explore the features of peptic ulcer disease, and analyze difference of incidence in difference months. Methods Gastroscopy results were collected and analyzed in our hospital. Results A total of 8592 cases of peptic ulcer were collected, including 6875 cases of duodenal ulcer, 1121 cases of gastric ulcer and 596 cases of compound ulcer, the detection rate were 12.72%, 2.07% and 1.10% respectively. Duodenal ulcer presented significantly more than gastric ulcer, the ratio was 6.13∶1. As to season changed, the detection rate of duodenal ulcer and gastric ulcer in the months when autumn turns winter were higher than in the months when winter turns spring. The detection rate of duodenal ulcers in winter and spring were higher than summer and autumn. Compound ulcer had highest incidence in winter and lowest in autumn. As to predilection site, gastric ulcer was mainly in gastric antrum, followed by gastric angle, duodenal ulcer was mainly in anterior wall. The peak age of duodenal ulcer, gastric ulcer and compound ulcer were 30~39, 40~49, and 40~59 years old. Conclusion Duodenal ulcer was remarked more than gastric ulcer. The detection rate of duodenal ulcer and gastric ulcer in the months when autumn turns winter was high than in the months when winter turns spring.
