Abstract:Abstract Objective To explore the effect of conventional gastrointestinal endoscopy and painless gastrointestinal endoscopy in the diagnosis of digestive tract diseases.Methods 62 patients with gastrointestinal diseases admitted to our hospital from October 2018 to October 2019 were selected and randomly divided into routine group (31 cases) and painless group (31 cases) according to the random number table method.The routine group patients were given routine gastrointestinal endoscopy for examination,and the painless group patients were given painless gastrointestinal endoscopy for examination.The routine group was given routine gastrointestinal endoscopy for examination,and the painless group was given painless gastrointestinal endoscopy for examination.After the examination,the examination-related indicators and patient satisfaction of the two groups of patients were compared.Results The excellent and good rate of patients in the painless group is higher than that of the conventional group.The intraoperative and postoperative heart rate,systolic blood pressure,diastolic blood pressure and other indicators are better than those of the conventional group.The incidence of adverse reactions and throat reflexes is lower than that of the conventional group.the above differences were statistically significant (P＜0.05).There was no significant difference in blood oxygen saturation between the two groups of patients after operation (P ＞0.05).Conclusion Compared with routine gastroscopy,painless gastroscopy has better examination effect,patient satisfaction and adaptability,fewer adverse reactions and higher safety.
