Abstract：Objective To explore the application and operation analysis of umbrella type spray tube and original straight head spray tube in endoscopic hemostasis with medical glue in patients with upper gastrointestinal bleeding.Methods A total of 202 patients with upper gastrointestinal bleeding who underwent endoscopic hemo-stasis with medical glue in Beijing Anzhen Hospital,Capital Medical University from January 2022 to December 2024 were retrospectively analyzed.According to the spray tube used,they were divided into straight head spray tube group(control group,147 cases)and hemostatic umbrella spray tube group(observation group,55 cases).The spraying effect data and endoscopic blockage of the two groups were analyzed.Results There was no significant difference in the treatment examination time between the observation group and the control group(P＞0.05).The spraying and observation time of the observation group was longer than that of the control group(P＜0.001).In the observation group,after spraying medical glue on the bleeding site of duodenal bulb ulcer and cardia laceration,the umbrella was retracted into the outer sheath tube,and the wound after spraying could be clearly observed.In the control group,after spraying medical glue,the lens was blurred,and the lens was withdrawn immediately.There were 52 cases of excellent lens clarity and 3 cases of good lens clarity in the observation group after medical glue spraying,there were 76 cases of excellent lens clarity,22 cases of good lens clarity and 49 cases of poor lens clarity in the control group,and the difference between the two groups was statistically significant(x2=31.954,P＜0.001).The proportion of rubber tube blockage in the observation group was lower than that in the control group[0(0/55)vs 7.5％(11/147)](x2=4.362,P=0.037).In recent 3 years,the number of endoscopic repairs due to the blockage of medical glue after spraying in the control group was 11 times,and the cost was 54 893 yuan.The medical glue was not blocked in the observation group,and the cost was 0 yuan.Conclusions The umbrella type spray tube used in endoscope can clearly observe the spraying effect of medical glue on the wound after bleeding,and the plug rate in the lumen and maintenance cost are lower than those of the control group.
