Study on the Effects of Different Dietary Preparation Methods on Capsule Endoscopy

Background: Capsule endoscopy (CE) examination has become the first-line diagnostic method for small bowel disease, and intestinal preparation is a key factor affecting the quality of CE examination. At present, there is no uniform standard for dietary preparation methods before CE at home and abroad, and there are few systematic comparative studies on the choice of dietary methods. Objective: To explore the best method of preparing diet for capsule endoscopy (CE) examination. Methods: 93 Patients who underwent CE examination in the digestive endoscopy center of Wuhan union medical college hospital in October 2019 were randomly divided into 3 groups. Group A (n = 31): 1 day before the examination; a diet with low-residue was given, and 1 day before the examination, fasting was started at 8 p.m. until the examination was completed. Group B (n = 30): a clear liquid diet was followed 1 day before the examination, and fasting was started at 8 p.m. 1 day before the examination until the examination was completed. Group C (n = 32): followed an ordinary diet 1 day before the examination, and began fasting at 8 p.m. 1 day before the examination until the examination was completed. Intestinal preparation of the same drug was performed in 3 groups, and the incidence of side effects and intestinal cleanliness of each group were compared. Results: There was no significant difference in cleanliness between the three groups (P > 0.05). The incidence of side effects in the three groups was 28.13%, 70.00% and 21.88%, respectively. The difference between group A and group B, group C and group B is statistically significant (P < 0.05). Conclusion: The three diet preparation methods of low-residue diet, clear liquid diet and ordinary diet can all achieve good intestinal cleansing effect. Clear liquid diet can not obviously improve the cleanliness of the small intestine, and there are relatively many side effects.
