To explore the detection and clinical characteristics of esophagus diverticulum by electronic gastroscopy.

The data of 155 patients with esophageal diverticulum diagnosed by electronic gastroscopy from January 2012 to October 2018 in Digestive Endoscopy Center of Ningxia Hui Autonomous Region People′s Hospital were retrospectively analyzed, including age, sex, diverticulum location, number and complications.

In the 48 850 patients undergoing electronic gastroscopy, both the prevalence and detection rate of esophageal diverticulum were 0.3%, of which 97.45% were single diverticulum, 2.55% were multiple diverticulum, and the proportion of asymptomatic diverticulum was 89.03%.In the incidence of esophageal diverticulum, chronic gastritis and peptic ulcer were most common in 61 to 70 years old, and the incidence rates were 94.2% and 9.7% respectively.The incidence rate of reflux esophagitis was only 7.1%.In different parts of the esophageal diverticulum with gastroesophageal reflux disease, the incidence rate of gastroesophageal reflux disease in the upper diaphragmatic diverticulum was up to 45.45%(5/11), followed by the middle esophagus 36.36%(4/11)and pharyngoesophagus 18.18%(2/11), with statistically significant difference(χ²=47.50, P<0.05). gastroscopic presentation of fungal esophagitis was in 4 cases(2.6%)and early middle esophageal cancer in 1 case(0.6%).

Electronic gastroscopy has diagnostic value for esophageal diverticulum, and it is worthy of clinical application.
