The Effect of Transcutaneous Electrical Acustimulation on Small Bowel Preparation for Capsule Endoscopy

Transcutaneous elctroacupuncture(TEA) at ST36 can improve gastrointestinal motility. Therefore,the investigators hypothesized that if TEA is applied to the preparation of small bowel capsule endoscopy, the small bowel peristalsis of patients can be regulated by electrical stimulation at (ST36). On the one hand, it can be used in combination with compound polyethylene glycol electrolyte powder, which is conducive to the discharge of small bowel contents and improve the imaging quality. On the other hand, it can improve the diagnostic rate by adjusting the intestinal transit time, And the completion rate of the examination can be improved by accelerating the gastric emptying time of capsule endoscopy. Therefore, in order to explore the effect of TEA stimulation at ST36 combined with polyethylene glycol powder on preparation for small bowel capsule endoscopy, the investigators designed this study.
