Filter by:The goal of this observational study is to learn about Influencing factors of intestinal microecological changes before and after colonoscopy. The main questions it aims to answer are: - [question 1] The process of colonoscopic gas insufflation affects the intestinal microecology. Will the use of carbon dioxide gas insufflation can reduce the changes of intestinal microecology after colonoscopy? - [question 2] Can the appendix act as a reservoir for microorganisms to accelerate the recovery of intestinal microecology after colonoscopy？ Participants will be asked to accept colonoscopy for once. Group 1(Control group) will be insufflated air during the colonoscopy; Group 2(Carbon dioxide group) will be insufflated carbon dioxide during the colonoscopy; Group 3(After appendectomy group) will be insufflated air during the colonoscopy. Since Group 1 is comparison group, the investigators will compare Group 2 to see if carbon dioxide gas insufflation can reduce the changes of intestinal microecology after colonoscopy. Meanwhile, compare Group 3 to see if the appendix can accelerate the recovery of intestinal microecology after colonoscopy.
Observation study comparing patient symptoms of bloating, pain, and nausea between CO2 insufflation vs. O2 insufflation in anterograde balloon enteroscopy.
It has been reported that carbon dioxide (CO2) insufflation can reduce patient pain and abdominal discomfort during and after colonoscopy. Its safety and efficacy during colonoscopy even under sedation has been already assessed in some earlier trials. Air insufflation is still the standard method, however, due a lack of suitable replacement of equipment or technical improvement in colonoscopy. The investigators use radio frequency identification (RFID) technology to record the number of times and duration in the toilet of the patient after colonoscopy examination. These data may be proxies for discomfort. With application of CO2 insufflation, the times and duration in the toilet after examination will decrease as well as patient's discomfort after procedure, and further improvement of patient compliance can be anticipated.
