Analysis of the endoscopic screening results of Beijing-Tianjin-Hebei Region Gastrointestinal Endoscopy Medical Association from 2016 to 2020 / 中华消化内镜杂志

ABSTRACT

Objective:To evaluate the development and application of gastrointestinal endoscopy technology in Beijing-Tianjin-Hebei (BTH) region from 2016 to 2020, and the impact of the corona virus disease 2019 (COVID-19) epidemic on gastrointestinal endoscopy screening and lesion detection rate of medical institutions.Methods:Data of gastroscopy and colonoscopy cases from 26 cooperative institutions in BTH Region Gastrointestinal Endoscopy Medical Association from January 2016 to December 2020 were collected by questionnaire. The number of gastrointestinal endoscopy, the detection of main lesions (including upper gastrointestinal malignant tumors, early gastric cancer and colon cancer), and the number of endoscopic treatment were retrospectively analyzed by year.Results:From 2016 to 2019, the number of gastroscopy and colonoscopy showed a yearly increasing trend with an annual growth rate of over 10%. Compared with 2019, the number of gastroscopy and colonoscopy decreased by 10.86% and 8.29%, respectively, in 2020 due to the impact of the epidemic. The annual detection rates of upper gastrointestinal malignant tumors, early gastric cancer and colon cancer were on a rise, from 7.22%, 1.49% and 8.98% in 2016 to 9.87%, 2.71% and 12.04% in 2020, respectively. The number of gastroscopic mucosal resection, submucosal dissection and colonoscopic endoscopic submucosal dissection increased yearly, from 2 132, 300 and 217 cases in 2016 to 5 466, 872 and 560 cases in 2020, respectively.Conclusion:The Medical Association has promoted the expansion of endoscopic screening and the application of endoscopic treatment techniques, resulting in a continuous increase in the endoscopy detection rate and early cancer diagnosis rate in the BTH region. The sharp decrease of gastrointestinal endoscopy procedures and the increase in the lesion detection rate in 2020 reflect the impact of epidemic COVID-19 on detection of gastrointestinal cancers.
