Objective:To investigate the clinical characteristics,and diagnostic and curative performance of patients with peptic ulcer disease(PUD)in Lhasa region.Methods:A retrospective analysis was conducted on 237 PUD patients who received diagnosis and treatment at Lhasa People's Hospital between September 2017 and December 2019.The general information of demographics,clinical presentations,treatment and outcomes of patients were investigated and analyzed.Results:In the PUD patients of this region,180 cases were male patients(75.9%),which was more than 57 female patients(24.1%),and 89 cases(37.6%)had smoking history with long term and 70 cases(29.5%)had history of heavy drinking.In the common comorbidities,39 cases(16.5%)were chronic liver disease,24 cases(10.1%)were hypertension,and 8 cases(3.4%)were arthritis(gout).Clinical symptoms presented in 234 PUD patients(98.7%),and the most common symptoms were respectively abdominal pain(200 cases,84.4%),hematemesis or melena(122 cases,51.5%),heartburn(90 cases,38.0%),and abdominal distension(84 cases,35.4%).The number of patients with multiple ulcers was 131 cases(55.3%),which was more than that of patients with single ulcers(106 cases,44.7%).The distribution of ulcer locations,from most to least frequent,was as follows:gastric angle(124 cases,52.3%),gastric body(72 cases,30.4%),antrum(69 cases,29.1%),pylorus(48 cases,20.3%),duodenal bulb(29 cases,12.2%)and gastric fundus(14 cases,5.9%).In the 235 patients whose treatment plans could be tracked,229 cases(97.4%)received standard acid-suppressive therapy and gastric mucosal protectant.In the 237 PUD patients,166 cases received follow-up,and 161 PUD patients provided feedbacks for symptom.The result showed that the symptoms of 158(98.1%)patients were alleviated or disappeared.In the 166 patients who received follow-up,49 cases underwent reexamination of endoscopy,and 11 cases(22.4%)of them appeared recurrence of ulcer.During the period of study,7 patients(4.2%)of 166 patients who received follow-up re-admitted to hospital due to PUD,and 7 patients(4.2%)died,and the main reasons of death involved to gastrointestinal bleeding,gastric cancer,stomach-related diseases,liver cancer,and coronary heart disease.Conclusion:The result of this study provided important information of clinical characteristics of PUD in the Lhasa region.The prognostic research of that is helpful to better understand the epidemiological characteristics and the status of clinical management for PUD in this region.However,this study still need larger sample size and further research to confirm and expand these results.
