About this study
Up to now, many studies has showed that compared with air insufflation colonoscopy, water-related colonoscopy could shorten the cecal intubation time and relieve the pain of the patients,especially for training the beginners,the investigators conduct this study to preform the "air assisted" water injection colonoscopy in experienced endoscopists.
Read the detailed description
In order to further develop water skills and apply the water assisted colonoscopy technique more flexibly, the investigators designed this study.
- Conditions
- Colon Disease;, Rectal Disease
- Being tested
- Air insufflation, Water injection, " Air assisted" water injection.
- Medical subject headings
- Colonic Diseases, Rectal Diseases
What participants receive
What participants receive. In a randomised study each person is assigned to one group by chance.
Air insufflationOther
Air is inflated into the bowel to help searching the cavity while advancing the colonoscope until reaching the cecum.
Water injectionOther
Water was injected through the working channel instead of air to follow the intestinal cavity until reaching the caecum .
" Air assisted" water injection.Other
Cut off air inflating before examination. Water was injected through the working channel to follow the intestinal cavity until reaching the splenic flexure, small amount of air inflating could be given to help searching the cavity until reaching the cecum.
| Study group | Role | What they receive |
|---|---|---|
| Air insufflation colonoscopy | Active comparator | Air insufflation colonoscopy is the conventional colonoscopy,which is inflating air to help searching the bowel cavity while advancing the colonoscope until reaching the cecum.All the patients were examined without sedation during the whole procedure. Receives: Other: Air insufflation |
| Water injection colonoscopy | Experimental | Water injection colonoscopy : Cut off air inflating before examination. Water was injected through the working channel to follow the intestinal cavity until reaching the caecum .The mucosa was observed by inflating the bowel with air while withdrawing the colonoscope.All the patients were examined without sedation during the whole procedure. Receives: Other: Water injection |
