Methods The study involved patients who visited at the department of endoscopy center at Hospital (Dongguan, China). Retrospective analysis of patients undergoing endoscopic removal of foreign bodies in the upper gastrointestinal tract from May 1, 2017 to May 1, 2020. We analyzed the patients' clinical data and compared the diagnosis and treatment effect between the painless gastroscope group and normal gastroscopy group. Results A total of 357 patients were included, 372 times of removal of foreign body under gastroscope were conducted. A total of 99 cases in painless gastroscope group were treated by painless gastroscope with painless sedation, 273 cases in normal gastroscopy group were treated by normal gastroscopy, among them, 15 cases were failed to removal the foreign body treated by normal gastroscopy, and turned into the painless sedation gastroscopy. Finally, 10 patients with foreign bodies were not removed and transferred to surgical department or higher level hospitals. In the treatment of endoscopic foreign body removal, the success rate of painless gastroscope group was higher (P<0.05), the complication incidence of mucosal injury, bleeding and perforation and cost per capita were lower than that of normal gastroscopy(P<0.05). Following painless sedation, the blood oxygen saturation, blood pressure dropped (P<0.05) and heart rate increased (P<0.05), the effect of the sedatives on the elderly was the most obvious (P<0.05), but it did not affect the patient's endoscopic operation, and the heart rate, blood oxygen saturation and blood pressure (P>0.05) after awakening.

Objective To explore the scientific evidence in optimization of diagnosis and treatment process for patients' convenience, we evaluated the clinical effect of gastrointestinal endoscopy with sedation on the safety, feasibility and advantage. Methods We enrolled 140 patients who came to our hospital for gastrointestinal endoscopy from June 2017 to March 2018. We used the convenience sampling method that the patients were randomly divided into two groups: observation group of 70 patients with combined endoscopy, and the control group of 70 patients with seperate endoscopy. We recorded and compared the two groups of patients of appointment time, inspection time, pain degree, patient satisfaction, and cost. Results The two groups were different in the appointment time, inspection time, heart rate changes after endoscopy, patient satisfaction and the costs (P<0.05), while no significant difference was found in blood pressure, blood oxygen degree, sedation, pain degree and discomfort reaction(P>0.05). Conclusion Combined sedative gastrointestinal endoscopy is safe and feasible in clinical application, with the advantages of low cost, less time, good patient cooperation, in line with the wishes of patients, and high satisfaction, which is worthy of popularization.
