The longer the observation time is after the injection of the corking solution into the anus, the better. This is because corkage mainly stimulates the mucous membrane of the rectum, and increases the peristalsis of the intestine through rectal stimulation. For constipated patients or patients with flatulence in the intestine, promoting peristalsis can resolve the gas in the intestine, thus promoting its discharge or the discharge of fecal residue or fecal lumps. Cecelia is a drug that promotes intestinal motility, which is stimulated to the rectum and plays a role. The longer the stimulation of the rectum, the better the effect of promoting gastrointestinal dynamics, so after the injection of Cecelia into the anus, try to persist for as long as possible, and generally the effect will be obvious after 5 minutes. If constipation often occurs, the open plug only solves the symptoms, can not effectively relieve the disease, but also need to improve the colonoscopy to further assist diagnosis and treatment.
