Abstract:Objective To select a better gastroscopy program by a comparative study of general gastroscopy with differential cardia and gastric fundus examination sequences.Methods The patients with general gastroscopy from January 2021 to April 2021 were divided into pre group and post group according to the examination sequence of cardia and gastric fundus, then divided into subgroups according to the amount of mucus Lake gastric juice. The duration of gastroscopy, visual field clarity, nausea of patients and satisfaction level of operators were compared. The application effect of pre cardia and gastric fundus pathway was analyzed.Results When there was less gastric juice, there was no significant difference in the duration and clarity of gastroscopy between pre and post groups. However, when there was more gastric juice, the duration of gastroscopy in pre group was significantly shorter than that in post group (P < 0.05). When there was more gastric juice, visual field clarity of fundus, body of stomach, angular incisures in pre group was better than that in post group (P < 0.05). In pre group, there was no significant difference in the duration and clarity of gastroscopy with more or less gastric juice. However, in post group with more gastric juice, the duration of gastroscopy was significantly longer than that with less gastric juice (P < 0.05), and visual field clarity of cardia, fundus, body of stomach was worse than that with less gastric juice (P < 0.05). When there was more gastric juice, the nausea reaction of pre group was lighter than that of post group (P < 0.05). The satisfaction level of pre group was higher than that of post group (P < 0.05), especially when there was more gastric juice (P < 0.01).Conclusion Pre cardia and gastric fundus pathway shortens the duration of gastroscopy, improves the clarity of visual field, reduces the range of gastroscope movement, reduces the occurrence of discomfort such as nausea, increases the satisfaction level of operators, especially when there are more gastric juice. It is worth promoting.
