Objective:To explore the effects of restricting swallowing combined with gargling strategy before examination on the quality of gastric preparation for magnetically controlled capsule gastroscopy.Methods:A total of 300 patients who underwent magnetically controlled capsule gastroscopy in Binzhou Medical University Hospital from March 2022 to August 2023 were selected and randomly divided into the control group of 150 cases and the intervention group of 150 cases at a ratio of 1∶1. Gastric preparation was conducted in the control group before the examination in accordance with the guidelines for magnetically controlled capsule gastroscopy. Restricted swallowing combined with gargling was added to the intervention group before the examination. The intragastric cleanliness, the degree of gastric mucosal visualization, the lesion detection rate, and the gastric examination time were used as evaluation indices.Results:Compared with the control group, the intervention group had significantly better scores in intragastric cleanliness (20.15±1.20 points VS 18.28±1.39 points, t=-21.884, P<0.001) and the degree of gastric mucosal visualization (20.30±6.67 points VS 18.80±1.04 points, t=-28.545, P<0.001), also showed higher lesion detection rate [94.7% (142/150) VS 77.3% (116/150), χ2=18.720, P<0.001], and lower gastric examination time (28.00±10.31 min VS 32.01±11.69 min, t=-2.328, P=0.023). Conclusion:Restricted swallowing combined with gargling strategy before examination can effectively improve the quality of gastric preparation for magnetically controlled capsule gastroscopy.
