OBJECTIVE: To systematically evaluate the application effect of simethicone combined with polyethylene glycol electrolyte powder for intestinal preparation before capsule endoscopy. METHODS: Pub Med
EMBase
Ovid
the Cochrane Library
Web of Science
Wanfang database
CNKI
CBM and VIP database were retrieved to collect the randomized controlled trial or clinical controlled study of simethicone combined with polyethylene glycol electrolyte powder for intestinal preparation before capsule endoscopy( the study group was given simethicone combined with polyethylene glycol electrolyte powder for intestinal cleaning
the control group was treated with polyethylene glycol electrolyte powder for intestinal cleaning).The retrieval time was from the establishment of the database to Dec.2019.Rev Man 5. 3 software was used for Meta-analysis.RESULTS: Eleven studies were included in this study
including 9 randomized controlled trials and 2 clinical controlled trials.A total of 1 198 patients were enrolled
with 598 patients in the study group and 600 patients in the control group. Meta-analysis results showed that intestinal bubble volume in the study group was less than that in the control group
and the proportion of patients with grade A intestinal bubble volume in the study group was significantly higher than that in the control group
the difference was statistically significant( OR = 3. 37
95%CI = 1. 96-5. 78
P < 0. 000 01). The intestinal cleaning in the study group was significantly better than that in the control group
and the proportion of patients with intestinal cleaning level 1 in the study group was significantly higher than that in the control group
the difference was statistically significant( OR =1. 48
95% CI = 1. 06-2. 08
P = 0. 02). The gastric passage time of capsule endoscopy in the study group was significantly longer than that in the control group
and the difference was statistically significant( MD = 3. 02
95%CI =0. 74-5. 30
P = 0. 009). There was no significant difference in the passage time of small intestine through capsule endoscopy between two groups( P = 0. 57). CONCLUSIONS: Simethicone can reduce the amount of bubbles in the intestinal tract and may improve the cleaning of intestinal tract
yet it does not increase the passage time of small intestine through the capsule endoscopy.
