Abstract:
Objectives To investigate the clinical characteristics and the regularity of seasonal changes that influence peptic ulcer (PU) in Nanehang area and to provide a theoretical basis for the treatment and prevention of PU.Methods Data collected from patients with PU diagnosed by clinic and gastroendoseopy between October 2003 to May 2008 were retrospectively analyzed.The PU was further divided into gastric ulcer,duodenal ulcer and complex ulcer.The lesion of gastric ulcer was calculated by five locations that were antral,angular,corporal,pyloric canal,fundic and cardia.The lesion of duodenal ulcer was calculated by five locations that were anterior wall of bulb,posterior wall,lesser curvature, greater curvature and postbulbar.The climate changes that influnced the incidence of PU disease were also observed.The detective rates of different types of PU were analyzed and its association with gender,age, lesion locations,seasons,Helicobacter pylori (Hp) infection and complications were also investigated. Results Among 83 888 patients who underwent endoscopy,PU was found in 21 308 patients (25.4%) including 66.33% duodenal ulcer,24.88% gastric ulcer and 8.79% complex ulcer.The male and femal ratio was 2.44 : 1 in PU,2.53 : 1 in duodenal ulcer,2.26 : 1 in gastric ulcer,and 2.33 : 1 in complex ulcer.The average age of patients with gastric ulcer was 48.0 years that was about 6.7 years higher than that of patients with duodenal ulcer.The prevalence of duodenal ulcer and gastric ulcer peaked in the 30- 39 years and 50-59 years,respectively.PU was more common from December to February (30.17%) and less common from June to August (22.54%) (P＜0.01) .The 57.43% of duodenal ulcer was found on anterior wall of bulb,18.26% on greater curvature,13.21% on lesser curvature,7.34% on posterior wall and 3.76% on postbulbar.The 45.69% of gastric ulcer was found on antral,20.54% on angular, 15.54% on corporal,9.36% on pyloric canal,and 8.87% on fundic and cardia.The 91.83% (12 318/ 13 414) of patients were positive for Hp infection.There was no significant difference of Hp infection among patients with different types of PU.The complications in patients with PU were bleeding (4.94%),pyloric obstruction (3.51%) and chronic perforation(0.04%).Conclusions The detective rate of PU in Nanchang area is 25.4%,which is higher than that in northern area of China.The incidence of PU is highly associated with sex,age,seasons and ulcer locations,with high Hp infections and a low incidence of complications.
